ReadMe

ReadMe is a San Francisco-based developer experience company founded in 2014 that builds interactive API documentation portals for software companies that want to give developers a best-in-class onboarding experience. The platform generates documentation from OpenAPI and Swagger specs and enhances it with a live API explorer that lets developers make real API calls directly from the documentation page, authenticated with their own credentials, removing the friction of switching to Postman or curl during evaluation. A standout differentiator is ReadMe's developer analytics dashboard, which shows API providers which endpoints are being called most, where developers drop off, and which documentation pages correlate with successful integrations, treating the dev portal as a product with measurable outcomes rather than a static publishing target. ReadMe also personalizes documentation experiences by injecting a developer's actual API keys and code examples into pages automatically, reducing copy-paste errors and accelerating time-to-first-call. The company raised $35M in a Series B in 2022 and serves customers including Cloudflare, Notion, and Intercom. Competitors include Stoplight, Redocly, and Mintlify, but ReadMe's analytics layer and personalization capabilities have established it as a preferred choice for developer-led growth teams that treat documentation as a revenue-driving channel.
