Gitar

Gitar is an AI code review platform that goes beyond commenting on pull and merge requests — it automatically fixes broken builds, failing tests, linting errors, and code-review findings, and validates every change against your CI pipeline before it is pushed. It works directly in the GitHub and GitLab PR interface, analyzes CI failures, deduplicates flaky tests, and runs natural-language repository rules from a .gitar/rules directory. Built by engineers from Uber's development stack and acquired by Sonar (SonarQube), Gitar is used by teams including SoFi, DeepL, and Altruist. It exposes a Bearer-token External API (api.gitar.ai/v1) on the Enterprise plan for installation health checks and GitLab project onboarding, and integrates with Buildkite, CircleCI, Bitrise, Jira, Linear, and Slack.

Gitar publishes 4 API contracts indexed on the APIs.io network, including GitLab MR Status API, GitLab Projects API, Installation Health API, and 1 more. Tagged areas include Company, Developer Tools, Code Review, CI/CD, and Code Quality.

The Gitar catalog on APIs.io includes 1 Spectral governance ruleset.

Gitar’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, support, and 24 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

8 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 53.8 — up to +11.6 composite points
Operational Transparency scores 18.4 — up to +10.6 composite points
Developer Ergonomics scores 58.9 — up to +8.2 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/gitar/apis.yml: open an issue on github.com/api-evangelist/gitar to ask a question or point us at an artifact you publish.
