Decap CMS

Decap CMS (formerly Netlify CMS) is an open-source, Git-based headless content management system for static site generators and modern frontend frameworks. It provides a web-based editorial UI for managing content stored directly in Git repositories, supporting collections of entries and media files, rich-text editing, editorial workflows (draft/review/publish), and i18n. Content operations are proxied to Git hosting backends (GitHub, GitLab, Bitbucket, Azure, Gitea) via their respective REST and GraphQL APIs. Decap Turbo adds a managed cloud layer with a database proxy, centralized authentication, user roles, real-time collaboration presence, and priority support.

Decap CMS is listed with 1 API on the APIs.io network. Tagged areas include CMS, Headless CMS, Git-based CMS, Content Management, and Static Site Generator.

Decap CMS’s developer surface includes documentation, engineering blog, pricing, and 7 more developer resources.

scored 2026-11-06 · rubric v0.27.0
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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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):
  • Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
  • MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
  • Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
  • 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)
  • Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
  • A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
11 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
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/decap/apis.yml: open an issue on github.com/api-evangelist/decap to ask a question or point us at an artifact you publish.

  description: 'Decap CMS communicates with Git hosting providers (GitHub, GitLab, Bitbucket, Azure, Gitea) through their
    REST and GraphQL APIs to read, create, update, and delete content entries, manage media file uploads, and orchestrate
    editorial workflows. The Decap client library wraps these provider APIs; there is no standalone Decap REST API server
    — all operations pass through the configured backend. Decap Turbo augments this with a database proxy that caches content
    and reduces direct Git API round-trips for improved performance and reduced rate-limit exposure.
