ILTER
Self-hosted AI gateway in a single binary
ILTER is a self-hosted AI gateway that runs as a single downloadable file — no extra servers to set up. Put it in front of any AI provider (OpenAI, Anthropic, and others) and instantly get spending limits, automatic PII protection before data leaves your network, smart routing between cheap and expensive models, and support for connecting AI to your own tools via MCP. Everything's managed from a built-in dashboard. Fully open source, free to run yourself.
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! 🙏
