Otari by Mozilla AI: your open-source gateway for AI governance

Otari is an open-source gateway that connects your agents or applications to any model, open-weight or closed. Give open-weight models the tools they’re missing, see where every token goes, and keep control of what you spend.
Open source on GitHub
They cost less, but without web search and code execution they struggle with real coding work.
You get every model, on someone else’s terms, with your keys and data on their side.
Once agents run every day, spend is spread across keys, teams and providers.
Use any model, open-weight or frontier, and switch without getting pulled into one provider.
Give open-weight models web search and code execution, and they come close to frontier capability at a fraction of the cost.
See where your tokens go, what your agents did and where they failed, and keep spend in check.
Open source you can run yourself, from Mozilla AI, which has no models or platforms to sell.
Plug an open-weight model into your coding agent and give it web search and code execution. Close to frontier on real tasks, at a fraction of the cost.
One open-source gateway for the whole team: every model, shared keys and budgets, and a view of what each agent did.
Cut model spend without cutting capability. See where every token goes, by team, model and agent, and run it yourself if you need to.

Point your coding agent at Otari’s OpenAI-compatible endpoint and choose an open-weight model. Turn on web search and code execution so the model can handle real coding tasks. The quickstart on otari.ai takes you through it in under 30 minutes.
Give each person, team or agent its own key in Otari. The activity view shows tokens and cost by key, model and month, and budgets let you set a limit for each team.
Yes. The code is on GitHub and you can run it on your own infrastructure. otari.ai is the hosted version, run by Mozilla AI.
A hosted router gives you many models on the provider’s terms. Otari is open source, so you can run it yourself and keep your keys and data under your control, and it adds server-side tools that bring open-weight models close to frontier capability.
