The control plane for trusted enterprise agents and models
See the performance of every agent and predictive model in a single pane of glass, with every action, token and dollar traceable by user and team.
Fiddler Centor Models power policy enforcement and continuous evaluation inside your network, avoiding external LLM API calls and their hidden costs.
Detects and redacts PII, PHI and secrets on the same request path — before a prompt reaches the model and before a response reaches the developer — with sub-80ms latency.
Keeps a living inventory of every connected agent and records each enforcement decision, with who triggered it and what happened, ready for GRC and AI regulation audits.

Instantly play, create and remix interactive mini-apps
A constantly updated feed of trending creations, top creators and curated categories such as meme, relax, strategy, action and puzzle.
A studio that lets you build a playable mini-app, then publish it to the community in minutes.
Take any published creation, change it and re-release your version — the engine behind most of the catalogue.
Everything runs in the browser with no install, and the same creations work on iPhone and Android through the Sekai app.
