What is stackrunner?
A managed X.509 CA service designed around the assumption that every cert has a defined expiry that the issuer enforces, not a soft policy you have to remember. Free tier hands you 25 certs on a shared intermediate; Dev tier provisions a per-customer intermediate in Google Cloud KMS and unlocks batch minting, scoped credentials, EST enrollment, and a self-signed birth cert for your own service mTLS.
Source lives in a public GitLab monorepo. This site documents the
public API surface and the credential model. Internal session
handoffs, runbooks, and pre-release notes stay in the repo’s
docs/ directory and aren’t published here.
