## Summary

Bump.sh is an API changelog and breaking change detection platform that automatically diffs OpenAPI specs on every deploy and notifies API consumers of changes.

## Company Overview

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.

## Frequently Asked Questions

### How does Bump.sh detect breaking API changes?
Bump.sh integrates with CI/CD pipelines to compare the current OpenAPI or AsyncAPI spec against the previously deployed version on every commit. It automatically classifies the diff by severity — breaking changes like removed fields or changed required parameters are flagged separately from additive changes — and can block a pull request merge or post a notification to API consumers before the change reaches production.

### What API specification formats does Bump.sh support?
Bump.sh supports OpenAPI 2.0, 3.0, and 3.1 specifications for REST APIs, as well as AsyncAPI 2.x for event-driven and message-based APIs. Both JSON and YAML formats are accepted.

### How does Bump.sh fit into a CI/CD workflow?
Bump.sh provides a CLI and GitHub Actions integration that compares the current API spec against the deployed version on each commit, generates a diff report, and posts results as a pull request comment — blocking merges for breaking changes or notifying API consumers about non-breaking changes automatically.

### Can API consumers subscribe to change notifications from Bump.sh?
Yes. Bump.sh allows API consumers to subscribe to a documentation page and receive email notifications whenever the API spec is updated with new breaking or non-breaking changes, keeping downstream teams aware without manual communication.

### Does Bump.sh render interactive API documentation for developers?
Yes. Bump.sh automatically generates and hosts a rendered documentation page from the OpenAPI or AsyncAPI spec, providing a browsable reference for API consumers with endpoint details, request/response schemas, and code examples.

### How is Bump.sh different from Stoplight or Readme for API documentation?
Bump.sh focuses specifically on API change management and automated changelog generation as first-class features, whereas Stoplight and Readme focus more broadly on API design and developer portal experiences. Bump.sh is the specialist choice for teams who need to communicate spec changes clearly across many consumers.

### Can Bump.sh handle multi-API or multi-version documentation setups?
Yes. Bump.sh supports organizing multiple APIs and multiple versions within a single account, allowing API-first companies to manage documentation and changelog for their entire API portfolio from one platform.

### Is there a free plan for Bump.sh?
Yes. Bump.sh offers a free plan for public APIs with one documentation hub. Paid plans starting at €149/month unlock private API documentation, multiple hubs, custom domains, and team collaboration features.
