Bump.sh

Bump.sh is a Paris-based API documentation and change management platform founded in 2020 that addresses one of the most painful operational problems in API-driven development: communicating breaking and non-breaking changes to the developers who depend on your API. The platform integrates into CI/CD pipelines and monitors OpenAPI or AsyncAPI specification files on every commit, automatically generating a structured diff that categorizes changes as breaking, non-breaking, or deprecated and publishes a human-readable changelog that API consumers can subscribe to. When a breaking change is detected — such as a required field being removed or a response schema changing — Bump.sh surfaces it in pull request checks before the change is deployed, giving API teams a last-chance gate to evaluate the impact and notify consumers proactively. Bump.sh also generates and hosts versioned API reference documentation from the same specs, providing API providers a single tool that covers both documentation publishing and lifecycle communication. The company raised seed funding and serves API-first companies, platform engineering teams, and companies with external developer ecosystems where breaking API changes carry customer retention and contractual risk. Bump.sh competes with Redocly, Stoplight, and conventional changelog tools, with its focus on automated change detection and consumer notification differentiating it from pure documentation platforms.
