Mintlify

Mintlify is an AI-native documentation platform for developer-facing products. It generates and maintains docs from MDX, source code, and OpenAPI specs, with automatic API reference generation, AI chat search, syntax highlighting across many languages, and Git-based publishing. In 2026 it added AI writing and maintenance agents and a metered AI-credit pricing layer. It is used by leading developer companies and suits engineering and developer-experience teams building polished, maintainable documentation.

Mintlify (mintlify.com) is an AI-native documentation platform used by developer-facing companies to build, publish, and maintain technical docs. It works from MDX content, source code, and OpenAPI specifications to generate polished documentation sites, including automatic API reference pages, syntax highlighting across many languages, AI-powered chat search, and Git-based publishing workflows that fit engineering teams. Mintlify has become a category leader, powering docs for well-known developer companies. In 2026 it introduced AI agents for writing and maintaining documentation and shifted toward a metered AI-credit pricing model layered on top of its plans. It raised a Series B in April 2026 that pushed total funding into the tens of millions at a valuation reported around half a billion dollars. Mintlify competes with Fern (now part of Postman), ReadMe, and open-source doc frameworks. Its strengths are design quality, developer ergonomics, and AI features that keep docs current. The main considerations are cost, since the AI-credit system and higher tiers can add up, and the fact that deeper AI usage is now billed separately from base plans.
