Railo
Auto-writes the security Fix PR. Not just the alert.
Security scanners find bugs. Your team still has to fix them. Railo closes that gap; it takes your open findings and automatically opens deterministic, test-passing Fix PRs for Python and TypeScript. No LLMs. No hallucinations. Deterministic AST engine + Z3 formal verification proves the exploit path is eliminated before any PR is created. Already patched HTTPie (34k★) and BentoML (9k★) in production. Free plan · Pro $49/mo · Team $199/mo
Hey Product Hunt!
I'm Zarif, a solo founder, building Railo from Bangladesh.
Here's the problem that kept me up at night:
Security scanners are incredible at finding bugs.
But they stop there. The alert lands. Engineers ignore
it. It piles up. Audit comes. Panic.
Nobody is fixing the actual bug.
So I built Railo.
Instead of another Jira ticket, Railo opens a verified
Fix PR directly in your GitHub — deterministic AST
transformation, Z3 formal proof that the exploit path
is eliminated, full test run. All before the PR is created.
Real proof, not demos:
→ HTTPie (34k★): PR #1942 — cross-platform path bug, fixed automatically
→ BentoML (9k★): PR #5704 — CWE-22 path traversal, eliminated
Both automated. Both pass CI. Zero false positives.
Zero LLM hallucinations.
Free plan is live right now. Connect your GitHub repo
in 60 seconds.
If you have a Python or TypeScript repo with security
debt sitting in your backlog — drop your repo URL below.
I'll personally walk you through your first scan.
