Agents
on Cloudflare's
edge.
Open Think is the open-source runtime for building stateful, streaming agents on Durable Objects, Workers AI, MCP, Browser Rendering, and the rest of Cloudflare's stack. Plugin-first. Tool-use native. Built in public.
Four primitives.
One plugin bus.
The same Cloudflare stack that powers the biggest sites on the internet now powers agents. Open Think wires it together so you can ship one on a weekend.
Durable by default
Every agent is a Durable Object with its own SQLite database. Sessions, fibers, and tool-call history survive Worker restarts. Hibernate when idle, wake instantly on the next turn.
Any model, one bus
Workers AI, Anthropic, OpenAI, Groq, Google, and 19 more providers behind a single plugin interface. Stream tool-use natively. Swap providers without touching your agent code.
MCP out of the box
Every agent is an MCP client the moment you deploy. Point it at Cloudflare's own MCP and you have a chat-first control plane for your whole account — with approve-to-run exhibits and rollback.
The Conductor reads your runtime and plans the next move.
Ask plain questions. The Conductor queries your live plugin catalog, proposes skill invocations as approve-to-run exhibits, or — in auto mode — runs the whole plan end-to-end with native tool-use streaming.
Three modes · propose · selective · auto — pick per-call.
Free to run.
Pro when you need hands.
Open Think is Apache-2.0 forever. Deploy it to your own Cloudflare account in a single click — zero cost when idle, generous free tier for Workers AI and Durable Objects out of the gate.
For teams who want a managed instance with priority support, or a one-shot concierge to configure everything live, we sell hands and time — not software.
"Durable, distributed, structurally safe, and serverless."
— Cloudflare, Project Think announcement
Cloudflare's Project Think laid out the third wave of agents: durable execution, fibers, facets, session APIs, and a sandboxed execution ladder. Open Think is a community reading of that vision — plugin-first, multi-provider, and deployable today by anyone with a Cloudflare account.
