Running autonomous coding agents locally is terrifying. One hallucination and they can delete your database or overwrite critical files. StuntDouble wraps any AI agent (like Aider or Claude Code) in a hardware-isolated Docker MicroVM. It injects eBPF C-code into your Linux kernel to silently drop destructive outbound network packets, and uses Git plumbing to allow instant, zero-copy filesystem rewinds if the AI deletes your code.
👋 Hey Product Hunt! I'm Rohan, the creator of StuntDouble.
A few weeks ago, I was running an autonomous AI coding agent on my laptop. It hallucinated, got confused, and almost dropped a local Postgres database I was
actively using for another project.
I realized that relying on "prompt engineering" (telling the AI "please don't delete my files") isn't real security. These agents have full root access to our
local filesystems and networks.
So I built StuntDouble. It’s a zero-trust wrapper that acts as a bodyguard for your local AI tools.
Here’s the cool tech behind it:
🛡️ eBPF Kernel Hooks: StuntDouble injects raw C-code into your Linux kernel to monitor every outbound network packet the AI sends. If it tries to hit a
destructive port (like Postgres or Mongo), the kernel silently drops the packet before it even leaves the virtual interface. The AI thinks it succeeded, but your
host is untouched.
⏪ Zero-Copy Time Travel: Before the agent spins up, StuntDouble uses Git's low-level core object database (git write-tree) to take an instantaneous,
cryptographic snapshot of your working directory. If the AI messes up your code, you just type stuntdouble rewind and your filesystem instantly reverts—without
polluting your commit history!
🌐 StuntNet Swarm: You can spin up an entire fleet of agents (stuntdouble swarm coder tester) isolated inside a custom Docker bridge network that hard-blocks
external internet access.
It works out of the box with Aider, Claude Code, and Ollama.
I built this entirely in Go, and it’s 100% open source. I'd love to hear your thoughts on using eBPF and kernel-level intercepts for AI safety. I’ll be hanging
out in the comments all day to answer any technical questions! Cheers! 🍻

Who hunted StuntDouble?
StuntDouble was hunted by Rohan Balsaraf. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
