Otari
Mozilla AIOpen, self-hosted OpenAI-compatible LLM gateway from Mozilla AI. It puts one endpoint in front of many providers with virtual API keys, budget enforcement and usage tracking, and ships server-side model-agnostic tools including sandboxed code execution in a Docker-isolated Python REPL. Built on Mozilla AI's any-llm, with a hosted platform running on the same core.

- hosted Otari.ai platform on the same core
Otari's gateway is Apache-2.0 and self-hostable via Docker Compose, and Mozilla AI's hosted Otari.ai platform runs on that same published code rather than on a separately licensed piece. A hosted convenience alongside a complete open core is not the same as gating: nothing in the source is withheld or paywalled.

The runtime modes page says standalone "serves the full API, stores keys, budgets, and usage locally" and that "Multi-provider fallback is therefore available without otari.ai when you configure a policy."

Adoption
1 low confidenceOtari's repository is very new and its star count remains low, so the adoption signal here is thin; no download, deployment or customer figure has appeared yet. Mozilla AI's any-llm library, which Otari is built on, has far more traction, but it is a separate product.
