Codemagic vs GitHub Actions
Codemagic and GitHub Actions bill differently, which matters more than feature parity here — Codemagic sells a subscription from $0 / month with a free tier, while GitHub Actions bills on usage (from $0.008/min (Linux)). Codemagic is CI/CD specialized for Flutter and mobile apps with Fastlane and code signing. GitHub Actions is GitHub-native CI/CD driven by YAML workflows inside the repo. Pick Codemagic when the job is conversion optimization and you accept medium lock-in; pick GitHub Actions when it is conversion optimization and you accept medium lock-in. The data we have shows Codemagic at mostly transparent pricing and docs with a polished developer experience, and GitHub Actions at mostly transparent pricing and docs with a polished developer experience. The honest trade-off: neither is universal — Codemagic is a poor fit for internal projects, and GitHub Actions is a poor fit for internal projects. Match the pricing model and lock-in level to how your team actually works, not the feature list.
Quick take
Codemagic is for CI/CD specialized; GitHub Actions is for GitHub-native CI/CD driven by YAML workflows inside; decide based on pricing model fit.

Frequently asked questions
Is Codemagic cheaper than GitHub Actions?
Codemagic starts at $0 / month on a subscription model; GitHub Actions starts at $0.008/min (Linux) on a usage model. That makes the sticker comparison depend on usage — a low entry price can get expensive once volume ramps, so price at your actual workload.
Can I migrate from Codemagic to GitHub Actions?
Migration is possible in either direction. Codemagic carries medium lock-in and GitHub Actions carries medium lock-in, so plan for meaningful but not blocking rework. Run both in parallel before you fully cut over.
Which has better developer experience?
Both Codemagic and GitHub Actions rate the same on developer experience (5/5). The decision on DX then comes down to taste — which CLI, UI, or workflow matches your team's habits. A short side-by-side trial is the quickest way to tell.
Is GitHub Actions a good alternative to Codemagic?
Yes — GitHub Actions is a reasonable alternative to Codemagic for conversion optimization. The practical differences are subscription-vs-usage billing and medium-vs-medium lock-in. If those fit your constraints better, treat GitHub Actions as a credible swap.
