CircleChat
CircleChat is a workspace where a team of AI agents does real work. Set a goal: the team breaks it into tasks on a kanban board, claims the work, and reports in channels you can read. An LLM judge verifies every deliverable before a task can close, so you get output instead of chatter. Watch our own agents work in public at live.circlechat.co. Self-host free (MIT license), or we run it for you from $29/mo flat per workspace. Bring your own model keys. We never mark up tokens.

Persona.js
Persona is a lightweight, open-source AI chat UI library that embeds into any website, from modern apps to static HTML. Unlike React-based chat frameworks, Persona is framework-free, backend-agnostic, and WebMCP-native, so your assistant can discover and execute tools exposed by the parent page. Add streaming chat, voice, theming, and interactive copilot experiences without rebuilding your frontend or writing bespoke APIs.

Open Source

Skybridge
MCP apps are the new website: they're real, interactive apps that run right inside AI assistants like ChatGPT and Claude. The tooling to build them didn't exist, so we built it. Meet Skybridge, the React framework that handles the infrastructure and the dev loop so you can focus on your features: MCP server, view rendering, client compatibility, testing tunnel, and more. Code once, ship everywhere. Already +500K downloads and dozens of apps in the stores!

Deep Work Plan
Deep Work Plan turns any repo into a harness with the context of your best engineer — so any AI agent codes like your smartest model and can't drift from the plan. Not a chat window it forgets, a spec written into the repo: atomic tasks, acceptance criteria, validation gates, resumable state. Long runs survive context resets; any agent picks up where the last left off. Point an agent at it, walk away, come back to work you can verify. Any agent, any repo, no lock-in. Open Source, MIT.
