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
# Add Fuzzbuzz without modifying your build$ fuzzbuzz build
# Auto-generate a fuzz test$ fuzzbuzz generate MyFunc
# Run fuzz test and find bugs$ fuzzbuzz check FuzzMyFunc

What is Fuzz Testing?
Deep-dive into what makes fuzzing the most effective way to find bugs
Learn MoreAll 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.

Fuzz testing in your CI/CD pipeline
Fuzzbuzz integrates with your CI/CD pipeline to ensure your latest changes are always tested, and bugs get caught before they reach production.

Real-time code coverage data
Fuzzing runs millions of inputs against your code. Cut through the noise by tracking your fuzz tests' progress with real-time code coverage reports.
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 →
Supported Languages
How it works
The only fuzz testing tool that integrates into the developer workflow at every step: from dev environment to CI/CD
Configure & test locally
The Fuzzbuzz CLI makes it easy (like, 3-steps easy) to configure, generate and validate fuzz tests for any project

Push up to GitHub (or GitLab)
Once you've added a couple of fuzz tests, simply push your changes up to CI/CD
