gittan.

How gittan works

Push code. Pipeline runs. Results stream to your terminal. No tabs, no waiting, no ceremony.

GitHub Actions

~90s

overhead before your code even starts running

  • Provision VM from scratch
  • Pull Docker images every run
  • Install dependencies every run
  • Sequential step execution

gittan

<1s

from push to first step executing

  • Pre-pulled images, warm runners
  • Sub-second container start
  • Layer caching across runs
  • Parallel DAG execution

Pipeline flow

What happens when you run git push origin main

git push

GitHub vs gittan

Ship a change to main.

GitHub

11 steps
  1. Create feature branch
  2. Push branch to remote
  3. Open pull request
  4. Wait for CI to start (~90s)
  5. CI runs, review requested
  6. Wait for reviewer
  7. Address review comments
  8. Re-request review
  9. Get approval
  10. Merge PR
  11. Delete branch

gittan

1 step
git push origin main

Pipeline runs during push. If it passes, main is updated. If it fails, push is rejected. Done.

Pipeline config layers

Three layers merge into a single pipeline. Org policies are enforced, team templates provide defaults, repos can add their own steps.

Injected

Org policy

Security gates, license scanning, image signing. Teams cannot remove these steps.

# org-policy.yaml (managed by platform team)
steps:
  - name: license-check
    image: gittan/license-scanner:20260601
    enforced: true
  - name: sign-image
    image: gittan/cosign:20260601
    enforced: true

Terminal feedback

Pipeline results stream to your terminal during git push. No browser needed.
