GitLab’s developer platform for building new services
Every new service starts with weeks of setup that has nothing to do with the feature it is meant to deliver. Theseus does that part once, for everyone.

- 1Scaffold One template generates a three-layer repo with CI already green
- 2Instrument Logging, metrics, and tracing are wired in from the first commit
- 3Declare You say what the service needs; the platform generates the chart
- 4Run anywhere The same artifact runs on a laptop, in CI, and in production
or scaffold one right now:
copier copy https://gitlab.com/gitlab-com/gl-infra/common-template-copier.git my-service --trustOne platform, every environment
Services declare what they need; the platform provides it — identically on a laptop, in CI, on GitLab.com, Dedicated, and Self-Managed.
Scaffold in minutes
Everything a new service needs — testing, deployment, a working local setup — is ready before you write a single line of actual feature code.
Monitoring for free
Your service is automatically watched and measured from day one. Nothing to configure.
Test locally, ship confidently
Run and debug your service on your own laptop with the exact same setup it uses in production. What works locally works for real.
Deployment, handled for you
Describe what your service needs; the platform turns that into a working, deployable setup automatically.
Secure by default
Security checks and compliance evidence are built in from the start, not something you have to remember to add later.
Weeks to hours
Setup that used to take weeks, for every team, now takes almost no time at all.
