Bump.sh vs Mintlify

Bump.sh is a hosted API documentation platform built by a small, fully remote French team led by CEO Sébastien Charrier. It takes OpenAPI and AsyncAPI definitions from your repository, turns them into fast reference docs, and diffs every new version so breaking changes are flagged and a changelog is generated automatically. It is docs-as-code for teams that treat the API contract as the source of truth.

Every commit or pull request can deploy or preview docs through the CLI or GitHub Action, and API hubs group many APIs into one portal with a custom domain. Pro adds branch management, an API Explorer, release rollback and the automatic changelog. There is no free plan: Basic costs $50 per month for 10 API docs, Pro $120 per month for 30 docs with a 14-day trial, and Custom adds SSO, embed mode and a 99.99% SLA. Open source projects can request free Pro access.

Bump.sh suits platform teams publishing many internal or public APIs, especially event-driven ones, since AsyncAPI support is first class. It is weaker for long guides and marketing-style portals. ReadMe and Mintlify are stronger for narrative docs, Redocly offers similar OpenAPI tooling with more linting and self-hosting, and Stoplight focuses on design-first editing.

The biggest recent change is its new managed MCP platform: Bump.sh generates and hosts MCP servers from API definitions and Arazzo workflow files, with auth and observability, so AI agents can call your API safely. Note that Basic includes only five MCP tools.

Mintlify is a documentation platform from a San Francisco startup backed by Y Combinator. It turns MDX and OpenAPI files stored in a Git repository into a polished, fast documentation site that deploys automatically on every push, and it has become the default docs choice for many AI and developer-tool companies.

Writers use MDX components such as cards, tabs, code groups and callouts, while OpenAPI files generate an API reference with an interactive playground. A web editor lets non-developers contribute without touching Git. Built-in search, analytics and reader feedback show what people look for, and an AI assistant answers questions from the docs content; Mintlify also publishes docs in formats that LLMs and AI agents read easily, such as llms.txt. The free Starter plan includes five editor seats, a custom domain, the web editor, authentication and an MCP server; Pro adds unlimited editors, the AI agent and assistant, automations and preview deployments, and Enterprise adds SSO, SCIM and a performance SLA.

Mintlify suits API-first and developer-tool companies that want great-looking docs in days rather than weeks. Pro pricing is steep for small teams, it is hosted only, and deep customization is harder than in a self-built site. Docusaurus is free and fully controllable, ReadMe offers deeper API usage analytics, and GitBook is broader for general product documentation.
