Bumpwise is an IntelliJ IDEA plugin that compares your code with the last published release of your library. It flags every change that would break your users, while you type, and shows you how to keep it compatible.
When a public method changes, Bumpwise highlights it and offers the fix that keeps old callers working, such as keeping the previous signature as @Deprecated and delegating to the new one.
Breaking on purpose? Bump the version updates your pom.xml, Gradle build, package.json or Cargo.toml in one step, keeping your format: 1.4.0-SNAPSHOT becomes 2.0.0-SNAPSHOT.
Each warning says what changed, which release it breaks and which version it requires. No build is needed: Bumpwise reads your source code directly.
Tools | Check API Compatibility lists every change with its impact, calculates MAJOR, MINOR or PATCH and drafts the changelog. Copy a summary for your pull request or save a SARIF report for code scanning.
When a commit breaks the published API without a version bump, Bumpwise asks before it goes in, or blocks it if your team prefers. Intended changes can be accepted with a reason in a shared .bumpwise.yml.
New required parameters, removed exports, interface methods and stricter types are found the same way, with each ecosystem's own conventions, such as /v2 module paths in Go.
Nexus, Artifactory and GitHub Packages. Credentials come straight from your Maven settings.xml, including encrypted passwords and tokens.
Commit a .bumpwise.yml to exclude internal packages, accept intended changes with a reason and decide what fails a check.
Coding agents connected to the IDE can ask Bumpwise whether their change breaks the API, through the IDE's built-in MCP server.
