Spec0

Ship with confidence

Governance & Quality

Spec0 diffs every change against the published spec, flags backward-incompatible changes, and runs lint and quality checks in CI — so a breaking change is caught in the PR that introduces it, not in a consumer's incident channel.

Before it ships

Catch breaking changes in the PR.

spec0 diffs every change against the published spec and flags anything backward-incompatible — a removed field, a tightened type, a deleted endpoint. Wire it into CI and a break is caught in the pull request that introduces it, not in a consumer's incident channel.

On every push

Quality gates that run themselves.

Enforce your own Spectral ruleset on every publish — naming, descriptions, error shapes, whatever your org standardises on. Bad specs are blocked before agents or consumers ever see them, so the catalog stays consistent as it grows.
