Free LLM-based Vulnerability Scans for Open Source Projects

Written by Gadi Evron | Mar 2, 2026 3:16:47 PM

AI is transforming vulnerability discovery for attackers and defenders alike. AI agents are now finding and exploiting vulnerabilities autonomously, at machine speed, and the open source projects the world depends on are squarely in the crosshairs. 

The cost of finding vulnerabilities is collapsing toward zero for attackers. It's time defenders get there too.

Introducing OpenAnt

That's why we're launching a free scanning program for open source projects using OpenAnt, our LLM-based vulnerability discovery tool (which we've also released as open source). 

OpenAnt from Knostic doesn't just flag potential issues; it uses LLMs to actually attack your code before reporting it vulnerable, cutting through the noise of false positives. It supports Python, JavaScript, TypeScript, Go, PHP, and C/C++.

Leveling the Playing Field: Free AI-Powered Vulnerability Scanning for Open Source

Open source maintainers are already stretched thin. They shouldn't have to face an AI-powered vulnerability onslaught without AI-powered tools of their own. That's why we'll scan open source projects for free - first come first serve.

Request a scan

Contact us at oss-scan@knostic.ai to tell us about your open source project and request a scan, or clone the GitHub repo and run it yourself.
