ILTER

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.
