Kelvane helps you bring legacy software into the agentic era securely It features an open-source Rust WebAssembly runtime to sandbox untrusted neural policies with zero ambient authority and strict CPU/memory caps Additionally, our platform compiles outdated backend code into clean Next.js + Postgres dashboards featuring built-in Model Context Protocol (MCP) tools Hot-swap policies mid-flight, and try it live with 10 free daily UTC credits
Hello Hunters! 😺
I'm excited to share Kelvane with the Product Hunt community today!
We built Kelvane because connecting AI agents to real-world code is currently a security and engineering nightmare. If you let an LLM write and execute guest plugins on your host system, you risk massive exploit vulnerabilities. On the other hand, if you try to connect an AI tool to a 10-year-old operational order desk, you find out it was never designed for structured API audit trails—let alone modern Model Context Protocol (MCP) schemas.
Kelvane solves both sides of this equation:
Our Open-Source Rust Wasm Sandbox (kelvane-runtime) gives you a safe, highly-restricted space to run untrusted neural policies with a hard per-call CPU/memory budget, zero ambient authority, and host-owned inference.
Our Modernization Compiler reads legacy zips or specs and instantly maps them to a modern Next.js + Postgres dashboard preview that is native-ready to serve as an agentic tool via built-in MCP
.
🎁 Free Credits for Hunters
We want you to try compiling your own apps or sandbox your custom policies. Every single day, you get 10 free credits (up to 40 free per month) in your UTC day grant—no credit card required
. First builds use 10 credits, and interactive edits/follow-ups use just 3.
Try the Live Platform: https://kelvane.dev
(The compiler runs on Fly.io's private network hosting, displaying live, compiled preview workspaces!)

We are pre-1.0 and actively looking for feedback from developers, security engineers, and founders. How are you handling the transition from legacy setups to agentic tools? What features would make Wasm sandboxing easier for your team?
I'll be here all day to answer your questions, dive into the architecture, or help you map your legacy setups!
Happy Hunting!
