ClusterFuzzLite - Simple Continuous Fuzzing That Runs In CI


ClusterFuzzLite is a continuous fuzzing solution that runs as part of Continuous Integration (CI) workflows to find vulnerabilities faster than ever before. With just a few lines of code, GitHub users can integrate ClusterFuzzLite into their workflow and fuzz pull requests to catch bugs before they are committed.

ClusterFuzzLite is based on ClusterFuzz.


Features

  • Quick code change (pull request) fuzzing to find bugs before they land
  • Downloads of crashing testcases
  • Continuous longer running fuzzing (batch fuzzing) to asynchronously find deeper bugs missed during code change fuzzing and build a corpus for use in code change fuzzing
  • Coverage reports showing which parts of your code are fuzzed
  • Modular functionality, so you can decide which features you want to use


Supported Languages

  • C
  • C++
  • Java (and other JVM-based languages)
  • Go
  • Python
  • Rust
  • Swift

Supported CI Systems

  • GitHub Actions
  • Google Cloud Build
  • Prow
  • Support for more CI systems is in-progess, and extending support to other CI systems is easy
