Find critical bugs, with ease
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.
- Bugs found at runtime; no false positives
- 20+ types of bugs (and adding more)
- Consistently reproducible bug reports
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.Learn more about the Fuzzbuzz workflow
Fuzzing 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.Learn more about the Fuzzbuzz workflow
See progress in real-time
With millions of inputs being run through your code, it can be hard to know how effective your fuzz tests are. 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
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 projectLearn more
Push up to GitHub (or GitLab)
Once you've added a couple of fuzz tests, simply push your changes up to CI/CDLearn more
Fuzz in CI/CD
The Fuzzbuzz platform hooks into your CI/CD and runs your tests as soon as changes are detectedLearn more
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.Schedule a Demo
