Jazzberry Launches: AI Bug Finding with Real Code Execution
"Jazzberry is creating the best AI agent for bug finding."
Founded by Mateo Perez & Marco Dewey
Hello everyone, meet Mateo and Marco. They're excited to introduce Jazzberry, an AI agent for finding bugs. Jazzberry is powered by running your code in a secure sandbox and integrates directly into your pull request workflow on GitHub.

Why Jazzberry was built
AI code generation has dramatically increased the amount of code that is written without the tools for bug finding keeping up, leading to a world with more buggy code that is hindering developers. To improve bug finding, the founders created an AI agent with the ability to run snippets of your code. Jazzberry is not just flagging potential issues based on code patterns; its observing the real behavior of your software. Here’s how it works.
- When you create a pull request, Jazzberry gets to work.
- Your repository is cloned into a microVM.
- The Jazzberry AI agent examines the contents of the pull request to guide its search. It can write and execute code in the microVM as it looks for bugs.
- Jazzberry returns a clear markdown table directly as a comment.

Real Bugs, Real Impact
The founders have already seen Jazzberry make a tangible difference for the company's early users. So far, Jazzberry has:
- Successfully identified a SQL injection vulnerability.
- Discovered a critical logical error in API key validation.
- Found an incorrect page navigation (see below, we are formerly known as Prophet)
