# Developer documentation for Indie SaaS

> Documentation platforms for API and developer-tool companies — Mintlify, GitBook, ReadMe, and the docs-as-marketing decision.

## TL;DR

Documentation tools for dev-tool indie SaaS now compete on aesthetic as much as feature set. Mintlify is the modern challenger with the docs aesthetic that defines the category (Anthropic, Cursor, Resend); GitBook is the broader knowledge-platform option; ReadMe serves enterprise API platforms with metering and developer-hub features. For new API docs in 2026, Mintlify is the default; the alternatives serve specific niches.
