Stoplight

Stoplight is a collaborative, design-first API platform providing a visual editor for OpenAPI specifications, interactive hosted documentation, automatic mock servers, API style guides and governance, and open-source tools including Prism (mock server), Spectral (JSON/YAML linter), and Elements (documentation components). Acquired by SmartBear in 2023, Stoplight is now positioned within SmartBear's API Hub solution group alongside SwaggerHub, with Spectral, Prism, and Elements progressively integrated into the unified API Hub experience. The platform supports OpenAPI v3.1, v3.0, v2.0, Arazzo v1.0, and AsyncAPI v2.x, with integrations for GitHub, GitLab, Bitbucket, and Azure DevOps. The Stoplight status page now redirects to stoplight.status.smartbear.com, confirming the operational consolidation under SmartBear.

Stoplight publishes 7 API contracts indexed on the APIs.io network, including Versions API, and 6 more. Tagged areas include API Design, API Documentation, API Governance, AsyncAPI, and Design-First.

The Stoplight catalog on APIs.io includes 1 JSON-LD context and 5 Spectral governance rulesets.

Stoplight’s developer surface includes developer portal, documentation, pricing, engineering blog, support, signup flow, getting-started guide, and 62 more developer resources.

What people ask Stoplight 1

The questions people put to an LLM, and the jobs they hand an agent, that Stoplight's APIs answer — each one linked to the operation that does it. Generated by API Evangelist

Stoplight Versions API Publish API docs anonymously to api-docs.io “Can I publish a Swagger or RAML spec as public docs without a Stoplight account?” Export an API version as OpenAPI, RAML or Stoplight “How do I download my Stoplight API version as an OpenAPI YAML file?” Import a spec into an existing API version “How do I sync my externally maintained Swagger file into an existing Stoplight version?” Re-publish docs for an API version “Can my CI pipeline automatically re-publish the docs after I import a new spec?”

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.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against 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 65 points between them, because both conditional facets apply and carry 35 points together. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 65% 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
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

Stoplight is an area vendor: providers adopt it to run part of their developer surface. This is the Kin Score checks its features can move for a provider that adopts it, what each one really earns, and what it earns nothing for.

Stoplight’s distinctive lift is Spectral: its OpenAPI ruleset flags missing info contact and description, operation descriptions, tags, operationIds, success responses and servers, which is a real route into Contract Quality, and a published Spectral ruleset is exactly what rules_present reads. The hosted docs add the usual reference, try-it and quick-start pointers. Every one of those needs the provider to act (fix the flagged spec, publish the ruleset, declare the pointers), and Stoplight contributes nothing to Agent Readiness beyond a code-sample link fallback; no llms.txt, MCP server, skills or agent card are offered.

Across 8977 providers that publish a contract, adopting Stoplight would move 8977. Median lift: composite +7.4 (90th percentile +10.0), agent readiness +1.2 (+1.3). Conditional rows excluded.

What Stoplight ships that earns nothing (3)

Hosted API documentation and developer hub — No Stoplight page claims llms.txt generation, and Stoplight’s own docs host returns 404 for /llms.txt.
Prism mock server (open source) — Prism serves the examples a document already has (or generates them dynamically); it writes none into the contract.
Platform style guides — A style guide kept inside the Platform is private; nothing is counted until the provider publishes the ruleset, and then the rules_present row applies.

A model, not a score. Adopting this vendor changes a provider's Kin Score only when the provider publishes the resulting artifacts on its own surface; nothing here writes a score, and no sponsorship or partnership can. The rating is not for sale → · Full vendor facets artifact

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Content, Documentation and Design Platforms	standard	26.8 (thin)	-	-
API Management (gateways, portals, service mesh, proxies)	standard	26.8 (thin)	-	-
APIs.guru OpenAPI Directory (API definition directory)	standard	26.8 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

AsyncAPI

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
