OneFuzz is a self-hosted Fuzzing-As-A-Service platform that lets developers launch continuous fuzzing jobs from a few VMs to thousands of cores, with built-in ensemble fuzzing, crash triage, and de-duplication. It was open sourced by Microsoft but was archived in late 2023 as development moved to an internal service.
Use cases
- run fuzzing at scale in ci/cd
- find crashes in my software automatically
- self-host a fuzzing service
- triage and dedupe fuzzing crashes
- run ensemble fuzzing across fuzzers
- debug crashes found by fuzzers on demand
When to choose
- you need scalable, developer-driven fuzzing integrated into CI/CD on Windows or Linux
- you want programmatic crash triage, de-duplication, and notification callbacks
- you're comfortable forking and maintaining the project yourself
When to avoid
- you want an actively maintained project - it was archived in September 2023
- you need turnkey hosted fuzzing without self-managing Azure infrastructure
- you only need a simple local fuzzer rather than an orchestration platform
