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! 🙏
