Hi Product Hunt!
I'm Louis, solo founder of Skint Labs. Today I'm launching WonderwallAi, an open-source AI firewall SDK I built because LLM apps are way too easy to abuse.
The problem is simple. Once you ship a product with an LLM in it, bad actors find ways in fast. Prompt injection, data leaks, jailbreaks, off-topic abuse. Most teams find out the hard way after something embarrassing ends up in a screenshot on X.
WonderwallAi sits between your users and your LLM and blocks four things. It catches prompt injection before it reaches the model, enforces topic boundaries so people can't jailbreak it, scans responses for API keys and personal data leaking out, and strips EXIF and GPS metadata from any uploaded files. It runs locally, makes zero external API calls, and adds under 2ms of latency.
It's MIT licensed. Run pip install wonderwallai and you're protected in 3 lines of code. There's also a hosted version with a dashboard, audit logs, and team controls if you'd rather not run it yourself.
Product Hunt exclusive: use code PRODUCTHUNT at checkout for an extra 25% off, on top of the 50% early bird deal that runs for the first 300 customers. Combined that's 75% off. Valid until Sunday May 3.
Would love your feedback, especially from anyone who's been burned by prompt injection in production. Ask me anything, happy to dig into the technical side. ✌️

Who hunted WonderwallAi?
WonderwallAi was hunted by Louis Constant. 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.
