## Summary

ReadMe is an API documentation platform with live in-browser API testing, personalized developer hubs, and usage analytics showing which endpoints developers actually call.

## Company Overview

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.

## Frequently Asked Questions

### What makes ReadMe different from static API doc tools?
ReadMe goes beyond static publishing by providing a live API explorer where developers authenticate and make real calls from the docs, personalized code samples injected with actual API keys, and usage analytics that show which endpoints and pages drive successful integrations.

### What is ReadMe?
ReadMe is an interactive API documentation platform that transforms OpenAPI and Swagger specs into developer hubs with live in-browser API testing, personalized code samples with real API keys injected, and usage analytics showing which endpoints developers actually call.

### How does ReadMe's live API explorer work?
ReadMe's API explorer lets developers make real API calls directly from the documentation page, authenticated with their own API credentials, without switching to Postman or curl. This removes friction during API evaluation and onboarding.

### Does ReadMe support OpenAPI and Swagger?
Yes. ReadMe imports OpenAPI 3.0 and Swagger 2.0 specifications to generate reference documentation automatically, and allows teams to enrich generated docs with custom prose, tutorials, and changelogs through a combined editor.

### What are ReadMe's developer analytics?
ReadMe tracks which documentation pages developers visit, which API endpoints they test in the explorer, and where onboarding sequences drop off — allowing API providers to treat their developer portal as a product and prioritize documentation improvements based on actual usage data.

### Can ReadMe personalize documentation for each developer?
Yes. ReadMe injects each developer's actual API key and account-specific values into code samples and the API explorer when they are logged in, so developers see working code they can copy and run immediately rather than placeholder values.

### Does ReadMe support versioning for APIs with multiple releases?
Yes. ReadMe supports multiple API versions simultaneously, allowing teams to maintain documentation for older versions while publishing new ones, with version selectors that let developers navigate between releases.

### What customization options does ReadMe offer?
ReadMe allows extensive branding customization including logo, colors, custom domains, CSS overrides, and custom landing pages, so developer portals match the company's brand identity rather than looking like generic documentation tools.
