OpenBrod is the home of a small family of developer tools: a long-standing archive library, a mocking framework for code you can't redesign, and a migration framework that proves your database schema. Free to use, open to contributions.
Each project solves a hard, concrete problem in real-world Java code bases, and is documented, tested and released like a product.
The real 7-Zip engine, bound to Java.
Extract and create archives with native 7-Zip performance, in-process through JNI. Streaming, callback-driven I/O, one jar for Windows, Linux and macOS.
Mock the code you can't inject into.
A mocking framework for JUnit 5 that changes classes in place: statics, private methods,
final classes, objects created with new and JDK types — no redesign for testability.
Schema migrations you can prove.
A migration framework for PostgreSQL and Hibernate that migrates a database with real data and proves the result matches the schema your application expects.
Open source doesn't mean unfinished. Every OpenBrod project follows the same rules.
Tools come out of long-running production projects, not from a whiteboard.
Clear behaviour, readable failures, and no surprises for the people who maintain the code.
Extensive test suites, CI on every change, and documentation written as a guide.
Open-source licenses, public issue trackers, releases on Maven Central.
Why “OpenBrod”? In Slavic languages, brod means a ford — the shallow place where you can safely cross a river. That's what these tools are for: getting your project safely across the hard parts, one stepping stone at a time.
Found a bug, missing a feature, or want to help? Every project has a public issue tracker, and pull requests are reviewed with care.
