SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

OSS-Fuzz provides distributed infrastructure for continuous fuzz testing of open-source projects, simplifying enrollment and ongoing verification.

Core Features & Use Cases

  • OSS-Fuzz automates fuzzing infrastructure setup, harness creation, and test execution across languages.
  • It offers a formal enrollment workflow, project management, and dashboards for coverage and bug tracking.
  • It enables local testing and repro steps via helper.py and project-specific Docker images.

Quick Start

Enroll your project with OSS-Fuzz using the official enrollment guide, then use the helper tooling to build, run, and inspect fuzzing results.

Frequently Asked Questions about ossfuzz

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up continuous fuzzing for an open source project?▼

OSS-Fuzz automates continuous fuzzing for open-source projects through a formal enrollment workflow. You configure project.yaml and Docker-based build scripts, enabling the infrastructure to automatically run fuzzing, track bugs, and analyze coverage across supported languages.

What is a fuzzing harness and how do I manage it locally?▼

A fuzzing harness exposes code paths to generated inputs for testing. You develop and manage these harnesses locally using helper.py and project-specific Docker images to execute reproducible fuzzing workflows before integrating with continuous testing.

Does OSS-Fuzz require Docker for local testing and build scripts?▼

Yes, Docker is required. OSS-Fuzz relies on Docker-based build and run scripts to create project-specific images, ensuring that local testing via helper.py produces reproducible fuzzing workflows identical to the distributed continuous testing infrastructure.

How do I track bugs and coverage analysis after running fuzz tests?▼

You track bugs and analyze code coverage by integrating with fuzz-introspector dashboards. OSS-Fuzz automatically routes continuous fuzzing results to these dashboards, providing detailed bug tracking and coverage analysis for your enrolled open-source project.

Can I use continuous fuzzing for projects written in multiple programming languages?▼

Yes, OSS-Fuzz automates fuzzing infrastructure setup, harness creation, and test execution across various programming languages. By configuring project.yaml and developing language-specific harnesses, you can continuously test multi-language open-source projects.

What are the limitations of local fuzz testing with helper.py?▼

Local fuzz testing with helper.py is limited to reproducible build and run steps within your environment. It lacks the distributed execution scale and automated continuous integration coverage analysis provided by the full OSS-Fuzz infrastructure.
