Using LibFuzzer or Honggfuzz?

Automate your fuzzing workflow with CI Fuzz — from generating harnesses to debugging crashes.

P.S. No need to give up your existing fuzzing engine — just let it find bugs with minimal effort from you.

LibFuzzer & Honggfuzz’s Limitations How CI Fuzz Can Help
Manual entry point identification ✅ Automatically identifies the most important functions to fuzz
Manual fuzz harness creation ✅ Fuzz tests are created, executed, and validated automatically using large language models (LLMs)
Every fuzz test has to be launched manually each time ✅ Executes fuzz tests until they reach the specified code coverage goal without human intervention
No built-in regression testing ✅ Built-in regression testing
Manual implementation of code coverage report ✅ Calculates line-by-line code coverage and aggregates results from multiple fuzz tests into a unified project overview
No crash triage or deduplication ✅ Automated bug deduplication. Integrates with test framework GTest
CI/CD integration is manual ✅ Supports any CI solutions, including GitHub Actions, Jenkins, GitLab
No built-in support of build systems ✅ Integrates with CMake and Bazel

Level Up LibFuzzer and Honggfuzz with AI Automation

CI Fuzz can use LibFuzzer or Honggfuzz as fuzzing engines and automate manual tasks associated with whitebox fuzzing, so you can start finding bugs with just one command.

 

CI Fuzz leverages AI Test Agent to:

  • Automatically identify entry points in your code
  • Generate and run fuzz harnesses (tests)
  • Monitor fuzz tests until desired coverage is achieved

All in one CLI command.

AI Test Agent

What our clients say about Code Intelligence

From 0 to 80 in 2 seconds. Code Coverage with CI Fuzz.

CI Fuzz analyzes code as it runs. Just like a unit test, but with AI support to efficiently cover all paths through the code.
Bug Find truly relevant and hidden issues and dig deeper every minute

Resolve issues seamlessly with instant access to a full stack trace at your fingertips.

Find truly relevant issues
Uncover real bugs in real time and say goodbye to theoretical issues and false positives. Find real issues with all the information needed to quickly reproduce and fix them.
Watchly Boost efficiency and reduce the number of tests needed

Let CI Fuzz automatically search for issues in the code and dig deeper every minute.

Boost efficiency
Conduct real-time code analysis with CI Fuzz. Take unit tests to the next level. It employs AI for comprehensive code path coverage and automatic generation of thousands of test cases.
Monitor Fix business critical bugs early in the development process

Maximize pipeline performance that doesn't compromise software integrity.

Fix business critical bugs
Test your code with maximum code coverage and automatically detect typical security relevant bugs like injections and remote code executions automatically in one go. Get fully covered to deliver highest quality software.
