OneFuzz

A self-hosted Fuzzing-As-A-Service platform

Project OneFuzz enables continuous developer-driven fuzzing to proactively harden software prior to release. With a single command, which can be baked into CICD, developers can launch fuzz jobs from a few virtual machines to thousands of cores.

Build Status

Features

Composable fuzzing workflows: Open source allows users to onboard their own fuzzers, swap instrumentation, and manage seed inputs.
Built-in ensemble fuzzing: By default, fuzzers work as a team to share strengths, swapping inputs of interest between fuzzing technologies.
Programmatic triage and result de-duplication: It provides unique flaw cases that always reproduce.
On-demand live-debugging of found crashes: It lets you summon a live debugging session on-demand or from your build system.
Observable and Debug-able: Transparent design allows introspection into every stage.
Fuzz on Windows and Linux: Multi-platform by design. Fuzz using your own OS build, kernel, or nested hypervisor.
Crash reporting notification callbacks: Including Azure DevOps Work Items and Microsoft Teams messages
