Fuzz Testing
for Developers

Generate & run millions of inputs against your code. Catch 20+ types of bugs including: memory corruption, denial of service, and race conditions.

Fuzz test your code with 3 commands

Download the CLI, run 3 commands and start finding bugs

All signal, no noise

As soon as you add a test, Fuzzbuzz starts generating and running inputs against your code, searching for critical bugs & vulnerabilities that other testing tools simply cannot find.

Detailed, reproducible bug reports

Get notified of bugs as soon as they're detected.
All bug reports are developer-friendly and come with a reproducible test case that you can run in your environment to cut down on wasted time.

Made for Developers

Fuzzbuzz is built from the ground up to be trivial to use and stay out of your way.

Other fuzzers require a deep understanding of your build and hours of configuration. With Fuzzbuzz, a fuzz test is not much harder to add than a unit test. Learn how →

$ fuzzbuzz build

Add Fuzzbuzz to your project without modifying your environment

$ fuzzbuzz generate

Generate fuzz tests for any function in your codebase

$ fuzzbuzz check

Validate your fuzz tests before committing code changes to CI/CD

How it works

The only fuzz testing tool that integrates into the developer workflow at every step: from dev environment to CI/CD

01

Configure & test locally

The Fuzzbuzz CLI makes it easy (like, 3-steps easy) to configure, generate and validate fuzz tests for any project

02

Push up to GitHub (or GitLab)

Once you've added a couple of fuzz tests, simply push your changes up to CI/CD


Learn more →
03

Fuzz in the cloud

The Fuzzbuzz platform hooks into your CI/CD and runs your tests as soon as changes are detected


Learn more →

Enterprise-ready

Fuzzbuzz is built to support enterprises of all sizes. Capable of being deployed completely on-prem, airgapped, with SOC2 Type II & ISO 27001 certifications to guarantee compliance.
