Stoplight

API design and OpenAPI governance, now part of SmartBear.

By SmartBear Software · Founded 2014 · Austin, TX · pe backed

Stoplight is the API design and governance specialist, best-in-class visual OpenAPI editor, style guides, and design-first workflows. SmartBear (PE-owned by Vista Equity Partners) acquired Stoplight in 2024, bringing it into the broader API tooling portfolio alongside ReadyAPI, SwaggerHub, and Pact. Best fit for teams that want design-first API governance and OpenAPI linting at scale, typically before they hand the contract to a runtime gateway. Trade-offs: not a runtime gateway, post-acquisition roadmap uncertainty as SmartBear consolidates with SwaggerHub, and pricing model has been in transition since the acquisition.

Best for

API platform teams (50-5,000 developers) implementing design-first workflows, OpenAPI style guides, and contract governance at scale, typically before runtime gateway selection.

Worst for

Pure runtime gateway needs (Kong, Apigee, cloud gateways), teams already standardized on Postman for design (overlap), or organizations sensitive to PE-backed roadmap uncertainty.

Vendor Trust is scored independently of product quality. A great product from an unfair vendor still earns a low trust score.
