Hey I'm the maker of ILTER, launching on Product Hunt next Tuesday and I wanted a place to actually talk with you before then, not just pitch.
Quick what-it-is: ILTER is a self-hosted AI gateway that sits between your app and AI providers. Any OpenAI-compatible client routes through ILTER to 9 different providers. Single binary, zero config, embedded dashboard. ./ilter serve and it's running.
Hey Product Hunt! 👋
I'm Yusuf. I built ILTER because every time I wanted to put AI safely in front of an app, I ended up stitching together five different tools just to get basic cost control and privacy. ILTER is a single download that sits between your app and any AI provider (OpenAI, Anthropic, and others) and gives you all of that out of the box:
🧩 MCP Gateway & Marketplace — connect your AI to internal APIs, your CRM, or MCP server, no changes needed
⚡ Smart Router — sends easy questions to cheap models and hard questions to powerful ones automatically
🌐 Smart Fallback — if one AI provider goes down, it switches to another automatically, nobody notices
🧠 Semantic Cache — recognizes when a question's basically already been asked and reuses the answer
🛡️ Prompt Guardrails — blocks prompt injection and toxic content before it becomes a problem
💰 Budget Control — set a hard dollar limit per API key so nobody wakes up to a surprise bill
🪪 PII Guard — strips emails, phones, and credit cards out of requests before they ever reach an AI provider
🌀 Agent Loop Detector — catches runaway AI agents stuck in a loop before they burn through your budget overnight
⏱️ Cron Engine — schedule recurring AI tasks like daily summaries or reports with zero extra infrastructure
📡 Observability — see exactly what your AI is doing: costs, requests, errors, all in one dashboard
📊 Dashboard — a clean web UI baked right into the binary, nothing extra to install
It's fully open source (Apache 2.0) and ships as one file — download it, run it, done.
Would love to hear what you think, and happy to answer anything about how it works! 🙏
