But if your tooling is tight, it\u2019s hard to beat for speed.<br><\/li>\n\n\n\n<li>GitFlow gives control, but also inertia: Manual versioning, CI duplication, and staging \u2260 prod headaches.<br><\/li>\n\n\n\n<li>CI\/CD shifts with the model: TBD pushes everything through a single fast pipeline. GitFlow splits builds per branch type (feature, release, hotfix), which increases fragility unless you invest in templating and infra discipline.<br><\/li>\n\n\n\n<li>Code review patterns diverge: TBD favors fast feedback and atomic diffs. GitFlow creates bloated PRs that take forever to review and often merge at the worst possible time (see: Friday disasters).<br><\/li>\n\n\n\n<li>Migration isn\u2019t just git commands: It\u2019s a mindset shift. You can\u2019t half-do TBD. It breaks unless everyone\u2019s aligned on short cycles, solid pipelines, and merge-first thinking.<\/li>\n<\/ul>\n\n\n\n<p>You\u2019re not choosing between GitFlow and Trunk-Based Development because you like the syntax of git checkout -b more in one. You&#8217;re choosing a <strong>release culture<\/strong>.<\/p>\n\n\n\n<p>One says: <em>\u201cWe merge fast, we deploy often, we own what breaks.\u201d<\/em><em><br><\/em> The other says: <em>\u201cWe branch deep, test slow, and ship when it feels safe.\u201d<\/em><\/p>\n\n\n\n<p>Both are valid. But if your CI is fast, your tests are real, and you\u2019re not in the business of shipping tax filing software to banks, there\u2019s a good chance GitFlow is slowing you down.<\/p>\n\n\n\n<p>This piece isn\u2019t going to regurgitate what you already know about main, develop, or feature\/*. Instead, we\u2019re going to walk through where GitFlow still makes sense (yes, it\u2019s not dead). Why Trunk-Based is more than a CI pattern, it\u2019s a cultural contract. How CI\/CD pipelines, QA habits, and even code review behavior shift depending on what branching model you choose and what it <em>really<\/em> takes to migrate from GitFlow to TBD without throwing your team into chaos.<\/p>\n\n\n\n<p>This isn\u2019t for junior devs or managers who just discovered GitHub Flow. This is for engineers, DevOps folks, and tech leads who\u2019ve been burned by broken pipelines, long-lived zombie branches, and Friday deployments that went nuclear.<\/p>\n\n\n\n<p>Let\u2019s break it down, not with theory, but with actual real-world workflows, tooling setups, and tradeoffs you\u2019ll hit in production.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Understanding the Two Models<\/strong><\/h2>\n\n\n\n<p>At a high level, Trunk-Based Development and GitFlow define how developers collaborate via branching, merging, and deploying code, but their operational assumptions are starkly different.<\/p>\n\n\n\n<p>Trunk-Based isn\u2019t a branching strategy. It\u2019s a bet: <em>\u201cWe trust our pipeline. We trust our tests. We ship small, and we ship often.\u201d<\/em><\/p>\n\n\n\n<p>It\u2019s not about living on main all day, nobody\u2019s actually committing straight to production. It\u2019s about keeping branches so short-lived they barely have time to go stale. You spin one up in the morning, get a PR out before lunch, and if it\u2019s behind a flag, it\u2019s merged before you sign off.<\/p>\n\n\n\n<p>TBD forces you to build muscle where it matters: pre-commit hooks, CI that doesn\u2019t flake, observability that actually tells you if the deploy is broken. If you\u2019re scared to merge every day, maybe it\u2019s not the strategy that\u2019s wrong, it\u2019s the lack of test coverage and the monster PRs you\u2019re trying to land on Fridays.<\/p>\n\n\n\n<p>The hard part isn\u2019t the git part, it\u2019s the discipline. You don\u2019t get to hide in a month-long feature branch and drop 2,000 lines of code with zero rebases. You merge early. You merge often. And if it breaks, the blame points straight back to a single commit, not a tangled pile of rebase spaghetti.<\/p>\n\n\n\n<p>If that sounds risky, GitFlow\u2019s over there with its seven branch types and stale PRs waiting for a Monday sign-off.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.aviator.co\/blog\/wp-content\/uploads\/2025\/07\/branch-types.jpg\" alt=\"branch types and stale PRs\" class=\"wp-image-4634\" srcset=\"https:\/\/www.aviator.co\/blog\/wp-content\/uploads\/2025\/07\/branch-types.jpg 1024w, https:\/\/www.aviator.co\/blog\/wp-content\/uploads\/2025\/07\/branch-types-300x169.jpg 300w, https:\/\/www.aviator.co\/blog\/wp-content\/uploads\/2025\/07\/branch-types-768x432.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>GitFlow is the comfort food of branching strategies. It feels safe. Familiar. Predictable. You\u2019ve got develop, you\u2019ve got feature\/*, release\/*, hotfix\/*, and probably a custom test-env\/* branch someone forgot to delete. Everyone knows where the code is, until no one actually does.<\/p>\n\n\n\n<p>It looks great on a whiteboard. But in the real world? It\u2019s a time machine to 2012. You\u2019re managing merge conflicts from two-week-old feature branches, staging is always \u201cone hotfix behind prod,\u201d and the QA team is the only thing between a bug and your SLA going nuclear.<\/p>\n\n\n\n<p>GitFlow doesn\u2019t scale well in teams that deploy daily. It assumes a world where releases are events, not defaults. And the ceremony around releases, version bumps, changelogs, \u201cmerge release back into develop\u201d, is fine when you ship quarterly. But for most modern teams, it\u2019s just busywork.<\/p>\n\n\n\n<p>That said, it still has a place. You\u2019re working in healthcare, finance, defense? GitFlow makes sense. Do you need multiple levels of sign-off, audit logs, reproducible builds, and tagged releases that can survive FDA audits? GitFlow will save your ass.<\/p>\n\n\n\n<p>Just don\u2019t pretend it\u2019s efficient. It\u2019s deliberate. It\u2019s structured. It\u2019s heavy. And if your team\u2019s velocity is capped by how long it takes to coordinate merges into release\/2.1.5, the bottleneck isn\u2019t git, it\u2019s the process you\u2019ve wrapped around it.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"630\" height=\"576\" src=\"https:\/\/www.aviator.co\/blog\/wp-content\/uploads\/2025\/07\/gitflow-process.png\" alt=\"gitflow proccess\" class=\"wp-image-4635\" srcset=\"https:\/\/www.aviator.co\/blog\/wp-content\/uploads\/2025\/07\/gitflow-process.png 630w, https:\/\/www.aviator.co\/blog\/wp-content\/uploads\/2025\/07\/gitflow-process-300x274.png 300w\" sizes=\"(max-width: 630px) 100vw, 630px\" \/><\/figure>\n\n\n\n<p>The decision isn\u2019t binary, many teams evolve from GitFlow toward TBD as their tooling matures. But picking the right strategy upfront saves months of friction and process rewrites down the line.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Shipping Daily vs. Shipping Safely<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>SaaS Teams Running TBD at Scale<\/strong><\/h3>\n\n\n\n<p>Let\u2019s stop pretending \u201cmultiple times a day\u201d is meaningful. That could be twice a day or 200 times. If you want real numbers:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Netflix<\/strong> does thousands of production changes daily.<br><\/li>\n\n\n\n<li><strong>Airbnb<\/strong> pushes code live <strong>50+ times per day<\/strong>.<br><\/li>\n\n\n\n<li><strong>Facebook<\/strong> had a trunk-based model internally even before GitHub existed, and shipped new code to prod every few minutes.<br><\/li>\n\n\n\n<li><strong>Google<\/strong>, the spiritual home of TBD, ties all engineers to a shared mainline and ships from it continuously.<\/li>\n<\/ul>\n\n\n\n<p>There\u2019s no develop. No release\/1.7.4. Just one branch <strong>main<\/strong> backed by CI\/CD muscle, test gates, observability, and rollback mechanisms that actually work.<\/p>\n\n\n\n<p>A flow from any of these teams looks like this:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>git push origin feat\/adjust-reco-weights<\/code><\/pre>\n\n\n\n<p>CI kicks in, lint, typecheck, unit tests, visual diffs, preview env build, feature flag checks, metrics pipelines, and if everything clears, it merges to main and ships.<\/p>\n\n\n\n<p>The deploy? It\u2019s not gated by a manager or QA checkboxes. It\u2019s gated by signal: <strong>test pass + observability + feature flag off = green light<\/strong>.<\/p>\n\n\n\n<p>Early merge? Cool, hide it behind something like LaunchDarkly or Unleash:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>if (featureFlags.newDashboard) {\n  renderNewDashboard();\n} else {\n  renderOldDashboard();\n}<\/code><\/pre>\n\n\n\n<p>That\u2019s it. Risk stays off until you\u2019re ready. But mainstays deployable 24\/7. If you\u2019re shipping once a week from a staging branch and calling it CI\/CD, this isn\u2019t that.<\/p>\n\n\n\n<p>TBD isn&#8217;t about speed for speed\u2019s sake, it\u2019s about <strong>making the deploy pipeline boring<\/strong>, and pushing all the real decisions (should we turn it on? who sees it?) up the stack where they belong.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>GitFlow: Regulated Industries or Versioned Software<\/strong><\/h3>\n\n\n\n<p>Example: Healthcare platform like Cerner, or a banking product like Temenos<\/p>\n\n\n\n<p>These environments require manual validation, audit trails, and versioned releases.

It <em>feels<\/em> structured. But if you\u2019ve worked on any project longer than a quarter, you know what actually happens: the YAML turns into a spaghetti monster with three times the branching logic and zero guarantees it works the same across branches.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code># Simplified, until it's not\nfilters:\n  branches:\n    only:\n      - feature\/.*\n      - release\/.*\n      - hotfix\/.*<\/code><\/pre>\n\n\n\n<p>You know what that means? Copy-pasted pipeline logic. Slightly different environments. Staging builds that <em>aren\u2019t<\/em> quite production. And someone asking six months later why release\/1.8.2 didn\u2019t run the Cypress tests because \u201cthey\u2019re only in the main pipeline now.\u201d<\/p>\n\n\n\n<p>This model spreads your pipeline surface across time and human memory. One misplaced condition or forgotten environment variable in release\/* and you get a false sense of test coverage. Meanwhile, prod quietly burns.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Versioning \u2260 Automation<\/strong><\/h4>\n\n\n\n<p>In GitFlow, version bumps aren\u2019t optional, they\u2019re part of the ritual. But unless you\u2019ve got something like<a href=\"https:\/\/github.com\/semantic-release\/semantic-release\" target=\"_blank\" rel=\"noopener\" title=\"\"> semantic-release<\/a> wired in, you\u2019re doing this:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>npm version patch\ngit push origin release\/1.4.1 --tags<\/code><\/pre>\n\n\n\n<p>&#8230;and then someone manually writes the changelog, forgets a fix, and tags the wrong commit. Teams try to duct-tape this with changelog generators, version scripts, and post-merge bots, but it always ends up brittle.<\/p>\n\n\n\n<p>And if you\u2019re running regulated releases, you\u2019ll probably also get this Slack:<\/p>\n\n\n\n<p>\u201cHey, can you re-tag v1.6.2? We forgot to include the legal notice footer fix before merge.\u201d<\/p>\n\n\n\n<p>Now your tag doesn\u2019t match what actually shipped. Good luck explaining that to an auditor.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>GitFlow CI Drift Is Real<\/strong><\/h4>\n\n\n\n<p>Staging is <em>supposed<\/em> to match production. But in GitFlow, staging lives off release\/, prod lives off main, and they\u2019re run through two different pipelines with two different sets of secrets and test gates.<\/p>\n\n\n\n<p>Ask anyone who&#8217;s managed this:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You forget to update the test config in release\/<br><\/li>\n\n\n\n<li>main uses a new linter version but hotfix\/ doesn&#8217;t<br><\/li>\n\n\n\n<li>Environment secrets got rotated for main, but not for release\/<\/li>\n<\/ul>\n\n\n\n<p>Suddenly, prod breaks, but staging was green.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>CI in GitFlow Is a Lie of Structure<\/strong><\/h4>\n\n\n\n<p>It <em>feels<\/em> structured. There are rules. There&#8217;s a flowchart. But that structure decays fast when the team moves fast. And unless you&#8217;re investing serious hours into pipeline reuse, YAML templating, and branching hygiene, it just becomes a fragmented mess.<\/p>\n\n\n\n<p>This is why infra folks quietly hate GitFlow. You&#8217;re not managing one CI pipeline. You&#8217;re maintaining four, and pretending they&#8217;re the same.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Branching Hygiene &amp; Code Review Practices<\/strong><\/h2>\n\n\n\n<p>Your branching model silently shapes how your team thinks about code quality, urgency, and responsibility.

Long-lived branches are just fear in disguise.\u201d<\/p>\n\n\n\n<p>Short-lived branches are a pressure valve: they force integration, not because your CI says so, but because your entire workflow breaks if you don\u2019t.

Enforce required status checks, code reviews, and prevent direct pushes.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code># Example GitHub rule:\n# - Require PR review before merging\n# - Require status checks (tests, lint, build)\n# - Disallow force pushes<\/code><\/pre>\n\n\n\n<p><strong>Step 2:<\/strong> <strong>Introduce short-lived branches only for major features<\/strong><strong><br><\/strong><strong><br><\/strong>Instead of weeks-long feature branches, encourage developers to break work into incremental PRs that can be reviewed and merged daily.<br><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code># Feature branch lives for 1-2 days max\ngit checkout -b feat\/user-invite-flow<\/code><\/pre>\n\n\n\n<p><strong>Step 3: Integrate a feature flagging system<\/strong><strong><br><\/strong><strong><br><\/strong>This enables teams to merge incomplete or risky features into main without exposing them in production. Tools like LaunchDarkly, Flagsmith, or Unleash allow granular rollout control.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>if (flags.newUserInvitesEnabled) {\n  renderInviteUI();\n}<\/code><\/pre>\n\n\n\n<p><strong>Step 4:<\/strong> <strong>Educate the team on commit discipline and CI coverage<\/strong><strong><br><\/strong><strong><br><\/strong>Teams used to GitFlow may be accustomed to batch testing at the release stage. In TBD, each commit or PR must pass linting, unit tests, and integration checks. Introduce pre-commit hooks and CI enforcement to catch issues early.<br><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code># Example husky hook for local linting\n\"husky\": {\n  \"hooks\": {\n    \"pre-commit\": \"lint-staged\"\n  }\n}<\/code><\/pre>\n\n\n\n<p><strong>Step 5: Phased rollout: Start with one service or repo<\/strong><strong><br><\/strong><strong><br><\/strong>Avoid flipping your entire org in one shot. Start with a single microservice or frontend repo to pilot the process. Track metrics like deploy frequency, PR size, and review time.<br><br>Once the team builds confidence, apply trunk based development git org-wide, adapting pipeline configs, permissions, and release policies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Best Practices (Without the BS)<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Trunk-Based Development: It Only Works If You Trust Your Pipeline<\/strong><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Protect <\/strong><strong>main<\/strong><strong> Like It\u2019s Production, Because It Is<\/strong><\/li>\n<\/ol>\n\n\n\n<p>If your main isn\u2019t protected with CI gates and required reviews, you\u2019re not doing TBD, you\u2019re just YOLO\u2019ing into prod. Every commit that hits main should be:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Linted<br><\/li>\n\n\n\n<li>Type-checked<br><\/li>\n\n\n\n<li>Fully tested (yes, even the \u201charmless\u201d ones)<\/li>\n<\/ul>\n\n\n\n<p>Use branch protection rules. Block direct pushes. Set hard status checks. This isn\u2019t \u201cnice to have.\u201d It\u2019s survival.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code># GitHub Actions\njobs:\n  validate:\n    steps:\n      - run: npm run lint &amp;&amp; npm test<\/code><\/pre>\n\n\n\n<ol start=\"2\" class=\"wp-block-list\">\n<li><strong>Enforce Quality at the Developer\u2019s Machine, Not Just CI<\/strong><\/li>\n<\/ol>\n\n\n\n<p>Don\u2019t wait for CI to catch broken code. Use pre-commit hooks via Husky or Left Hook:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>\"husky\": {\n  \"hooks\": {\n    \"pre-commit\": \"lint-staged\"\n  }\n}<\/code><\/pre>\n\n\n\n<p>Make it impossible to push sloppy code. Local automation should mirror your CI as closely as possible.<\/p>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li><strong>Kill the Zombie Branches<\/strong><\/li>\n<\/ol>\n\n\n\n<p>Branches shouldn\u2019t live more than a day or two. If your branch has a Slack thread longer than the code it adds, you\u2019ve missed the point. Keep changes small. Merge fast. Delete immediately.<\/p>\n\n\n\n<p>Squash merge is standard, nobody wants to review 20 commits that just say \u201cfix\u201d or \u201cWIP\u201d.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>GitFlow: You Chose Complexity, Now Own It<\/strong><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Rebase Constantly or Prepare for Merge Purgatory<\/strong><\/li>\n<\/ol>\n\n\n\n<p>If you\u2019re using GitFlow, your feature\/* branches will rot in days if you don\u2019t stay synced with develop. Force your team to rebase early and often. Merge conflicts aren\u2019t an accident, they\u2019re the default when code diverges for too long.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>git checkout feature\/add-user-form\ngit fetch origin\ngit rebase origin\/develop<\/code><\/pre>\n\n\n\n<p>And if rebasing causes too much pain, it means your features are too large or too tangled. That\u2019s not Git\u2019s fault.<\/p>\n\n\n\n<ol start=\"2\" class=\"wp-block-list\">\n<li><strong>Name Like You Deploy<\/strong><\/li>\n<\/ol>\n\n\n\n<p>CI can\u2019t parse \u201cfinal-bugfix-done-finally-v2\u201d. Use patterns that mean something:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>release\/2.1.0<\/li>\n\n\n\n<li>hotfix\/login-button-crash<\/li>\n<\/ul>\n\n\n\n<p>It\u2019s not just about clarity, it\u2019s about automation. CI\/CD tools hook into these names to decide which jobs to run. A random name breaks the logic and deploys the wrong artifact.<\/p>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li><strong>Don\u2019t Let Staging Drift Into a Parallel Universe<\/strong><\/li>\n<\/ol>\n\n\n\n<p>Staging = production, or it\u2019s a lie. That means:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Same test suites<\/li>\n\n\n\n<li>Same secrets (or at least synced)<\/li>\n\n\n\n<li>Same CI config<\/li>\n<\/ul>\n\n\n\n<p>When staging runs from release\/* and production runs from main, it\u2019s shockingly easy to forget a test step or config tweak and ship something broken to users. If you\u2019re not syncing CI logic across branches, you\u2019re playing whack-a-mole with bugs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>When to Use Which? Decision Guide<\/strong><\/h2>\n\n\n\n<p>Choosing the right Git strategy comes down to your team\u2019s structure, release cadence, and appetite for process vs speed. Here&#8217;s a quick lookup table:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh7-rt.googleusercontent.com\/docsz\/AD_4nXdoakI66kXoxSRjjVKpOa2nte2oxP385nLLB0Fdlprpw-OGwkavskfPhSp1lS8JhvFx0nEwtKpvIEEYpfnRfa2Q2-mgWwNsjXSJ98gckV4RVgzHnQqYZMvv0-0X1fl-r8ZSnreDBQ?key=yTMH7XeTMjeAwX61tiMQ7Q\" alt=\"Git strategy\"\/><\/figure>\n\n\n\n<p>No model is inherently better, it\u2019s about aligning branching with your deployment and QA strategy. Many modern orgs even use a hybrid: Trunk-Based for internal services, GitFlow for client-facing or regulated products.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Conclusion<\/strong><\/h2>\n\n\n\n<p>The git model isn\u2019t the hard part. What matters is whether your team can ship safely without hiding behind release branches or praying to the CI gods. GitFlow works when the process is the product. Trunk-Based works when delivery is.<\/p>\n\n\n\n<p>Most teams don\u2019t need a perfect model, they need a consistent one that fits their tooling and release expectations. If your deployment pipeline is solid, your tests are honest, and your team doesn\u2019t fear shipping daily, GitFlow probably isn&#8217;t helping you, it\u2019s just comforting you.<\/p>\n\n\n\n<p>Pick the strategy your team can <em>actually sustain<\/em>, not the one that looks best in a slide deck.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>FAQs<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Can I combine both GitFlow and Trunk-Based Development?<\/h3>\n\n\n\n<p>Yes, many teams run a hybrid. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use Trunk-Based in internal services where speed is critical.<\/li>\n\n\n\n<li>Use GitFlow for public-facing SDKs, regulated modules, or components that follow a formal release cadence.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. How do I do hotfixes in Trunk-Based?<\/h3>\n\n\n\n<p>Trunk-Based doesn&#8217;t use hotfix\/* branches like GitFlow, but urgent fixes still follow a controlled process:<\/p>\n\n\n\n<p>Branch from main:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>git checkout -b fix\/payment-null-check main\n\n<\/code><\/pre>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Make the fix, open a PR with required checks.<br><\/li>\n\n\n\n<li>Merge to main and trigger deploy.<br><\/li>\n\n\n\n<li>If needed, use a feature flag or version tag to track the change.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">3. Why is GitFlow considered outdated by some teams?<\/h3>\n\n\n\n<p>GitFlow came from an era when:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Releases happened monthly or quarterly<br><\/li>\n\n\n\n<li>Deployments were manual and high-risk<br><\/li>\n\n\n\n<li>Feature flags and automated tests were rare<br><\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. Is TBD suitable for open-source projects?<\/h3>\n\n\n\n<p>Mostly not. In open source, contributions come from many distributed developers, and code often waits for review. Trunk-Based Development assumes Fast merges, Small, atomic commits, Continuous deployment.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.aviator.co\/flexreview\"><img decoding=\"async\" src=\"https:\/\/www.aviator.co\/blog\/wp-content\/uploads\/2024\/07\/blog-cta-8FR_CTA.svg\" alt=\"flexreview teams\" class=\"wp-image-2493\"\/><\/a><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Trunk-Based Development vs GitFlow isn\u2019t just about git commands it\u2019s about release culture.
