How it works

GitHub stays in charge.

Manzanita replaces only the machine underneath your existing job. Workflows, secrets, caches, logs and artifacts stay on GitHub.

01

Install the GitHub App

Grant access only to the repositories that need macOS CI.

02

Change one runner label

runs-on: manzanita-standard. Nothing else in the workflow changes.

03

Get a clean Mac every job

Each job starts in a prewarmed macOS VM that is destroyed afterward.

Flat-rate pricing

not build minutes.

Free trial: one Standard runner for 14 days or 300 build minutes, whichever comes first. No card. Add runners for parallel jobs. Usage above 15,000 minutes per runner in 30 days starts a conversation, never a surprise charge. Early-access pilot without a contractual SLA · pilot terms.

Security

Trust the lifecycle,
not a black box.

The control plane never sees your source or build logs. A disposable VM checks out from GitHub with short-lived credentials, uploads logs and artifacts back to GitHub, then is destroyed. Runners are Manzanita-owned Apple Silicon in Menlo Park, California, operated by the people who answer support.

run by real people.

Manzanita is an operator-run service from Second Loop. Pilot customers work directly with the team that runs the hardware.
