Show HN: Takumi – An AI Security Engineer that found 10 zero-days (Vim, Next.js)

After hundreds of manual pen-tests we wondered: could an LLM-powered agent handle almost all the work of a security engineer? Takumi was the answer: a resounding yes. He is always available on Slack, just like another other colleague:

- Leave it to Takumi—no prompt-tweaking needed: he auto-researches, analyzes code, and delivers concise reports - Works 24/7 to discover the logic-level flaws that SAST tools often miss, such as broken access control and auth bypasses - Has already filed real CVEs during private internal tests (Vim and Next.js being two major examples)

Takumi is a SaaS product only costing $500/month. If you're an open-source developer, we also provide a program that lets you use it free of charge!

We are eager to receive feedback, so please do not hesitate to share your experience with us! In addition, please feel free to comment if you have any questions whether its about the setup, the security reports, or anything else!

Thanks a lot of taking a look!
