BlastRadius
Speed up Java CI by skipping unaffected tests safely.
Stop running your entire 45-minute test suite for a 2-line code change. BlastRadius uses a precise Java agent to map exact runtime dependencies, dropping your CI test times by 45% to 71% with zero flakiness heuristics.
I built BlastRadius after having to watch CI pipelines burn compute time (and company money) running the same static tests over and over again for isolated code changes.
Most Test Impact Analysis tools fail because they are either too complex to self-host or rely on predictive models that miss critical bugs.
BlastRadius takes a deterministic approach using a Java agent to track actual runtime class loading.
We replayed thousands of real-world commits against large Open Source projects and safely cut down test loads by up to 71% without a single missed test!
It's completely open-source, supports Maven/Gradle + JUnit 5, and plugs into your existing GitHub Actions or GitLab caches natively.
I'd love to hear your thoughts, answer any architectural questions, or help you figure out how to drop it into your current Java/Kotlin repos!
