Bump.sh generates interactive API docs from OpenAPI/AsyncAPI specs with automatic changelogs. See pricing, features, pros, cons, and FAQs.
Bump.sh is a docs-as-code API documentation platform that renders OpenAPI, AsyncAPI, and Arazzo specification files into hosted, interactive reference sites. Instead of manually writing and updating API documentation, teams commit their spec files and let Bump.sh regenerate the docs automatically whenever the spec changes.
The company was founded in 2020 by CEO Sebastien Charrier in Angers, France, after he experienced the pain of maintaining hand-written API docs while rewriting a payment API at a previous company. Bump.sh operates as a small, fully remote team based in France.
Core capabilities include server-side rendering built to handle very large OpenAPI files, an automated changelog that flags breaking changes between spec versions, an in-doc API Explorer with OAuth auto-fill for testing endpoints directly from the documentation, and Hubs for publishing a catalog of multiple related APIs under one portal.
Bump.sh also supports CLI and Git-based CI/CD integration (GitHub, GitLab) so documentation updates ship as part of the normal deployment pipeline, plus branch previews, release rollback, and Slack notifications on higher-tier plans. More recently the company added MCP (Model Context Protocol) tooling so AI coding agents can query API references programmatically.
Bump.sh has no permanently free public tier; pricing starts at $50/month for the Basic plan (10 API docs, 3 internal users, 20 guests). The Pro plan is $250/month with a 14-day free trial and adds the API Explorer, private MCP servers, and full CI integration. An Enterprise/Custom plan adds SSO, an SLA, and unlimited users at custom pricing.
Verified open-source projects can apply for free access to the Pro plan, which is a notable exception to the otherwise fully paid pricing model.
