| Blaze vs GitHub Actions

GitHub Actions is the default CI/CD for GitHub repositories. The default runners are billed by the minute.

Blaze is a drop-in replacement that gives each macOS job its own 4-core Apple Silicon VM at a fixed monthly cost, with unlimited minutes.

On GitHub you pay for minutes. On Blaze you pay for how many jobs can run at once: each macOS unit is one job at a time, on its own 4-core, 12 GB VM, for €125 a month however long it runs.

At $0.062 a minute, €125 buys about 39 hours of GitHub-hosted macOS a month. Below that, GitHub is cheaper.

What Blaze won't do is run more at once than you've bought. If ten jobs arrive on three units, three start and seven wait. GitHub starts all ten and bills every minute. Coding agents open more pull requests, and every pull request runs your workflows. On Blaze that means a longer queue, not a bigger bill. When the wait starts to matter, add a unit.

Switching from GitHub Actions to Blaze takes one line change:

# Before
runs-on: macos-latest

# After
runs-on: blaze/macos-latest

That's it. Everything else stays the same—your workflow steps, caching, artifacts, and secrets all work exactly as before.
