Find and fix problems in your AI agents before users do
See every message, tool call and decision in a run, with inputs, outputs and durations, so you can pinpoint where a run broke down.
Recurring failures are grouped into issues with severity, affected users, last-seen time and a confidence score, instead of scattered alerts.
An agent investigates issues and automates follow-up across Slack, the web app and MCP, so debugging happens where your team already works.
Run scenarios against a change on a pull request and compare results with real traffic to catch regressions before merge.

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.
