I'm Jordan. I work @cloudflare on the agent experience team.

I build small tools for AI agents.. memory, sandboxes, control surfaces, browser automation, Cloudflare stuff. I write about it at coey.dev.

• loop: a chatbot that builds working Svelte widgets while you talk. One long session per account. Older messages roll into a vector store. Reset if you want to start over.
• vibe-cdn: a Cloudflare game stack for heavy browser games. Drag a .glb onto the page, get an edge-cached URL back. Multiplayer arena, leaderboards, saves. Live demo.
• cloudbox: synthetic cloud computers for training and evaluating long-horizon agents on Cloudflare. Persona, filesystem, artifacts, collaborators, simulation, retrospective.
• deja: persistent memory for agents. Agents learn from failures. Deja remembers.
• capa: turn an OpenAPI spec into a Cloudflare Worker service binding. Every call returns the upstream result plus a proof bundle you can act on. Stripe, GitLab, Jira so far.
• terrarium: one-level orchestration harness for composable AI subagents.

Some of my favorites from coey.dev/blog.

• Patience: You've Never Controlled Anything: what Memento taught me about prompting agents.
• Campfire: The Oldest Protocol: every storytelling medium had a context window. We've always been writing prompts, we just called them stories.
• Prompts Are Wishes: every prompt is a hypothesis. The guardrails are somewhere else.
• Liquid Primitives: five parts of your stack to hold loosely.
• Worker Loaders as a Place: Dynamic Workers clicked when I stopped thinking about the API and started thinking about the room.

More at coey.dev/blog.

• lab: sandboxed isolates on Cloudflare Workers with typed capabilities. Effect + Worker Loaders.

• cloudshell: your personal terminal in the cloud. Deploy in seconds, access anywhere.
• filepath: personal Cloudflare-hosted development environment. Work lives in conversations, not terminal tabs.
• agent-human-bridge: auditable agent and human software-building protocol designed to pass a human safety review.
• living-artifact: physical and digital artifacts and tiny devices.

• unsurf: turn any website into a typed API. Scout, replay, auto-heal.

• t2t: voice-to-text with MCP support and system-wide dictation.
• machinectl: MCP server that lets AI control your machine from any device.
• cloudterm: DOM-rendered web terminal emulator.
• firestore-mcp-kit: build secure, typed MCP tools backed by Firestore with explicit Zod schemas.
• inbox.dog: OAuth for email, simplified. Gmail access tokens without implementing OAuth yourself.
• anytoolhq: generate tools for AI agents on demand.
• gateproof: E2E testing harness. Observe logs, run actions, assert results.

• remote: bun create remote-app my-app. SvelteKit, auth, DB, Cloudflare deployment.
• UserDO: per-user Durable Objects as data pods.
• blaze: real-time documents on Cloudflare. Firestore feel, Cloudflare price.

• flue-snippets: real, runnable Flue agents on Cloudflare. Every snippet ships an E2E test that deploys, asserts, and tears down.
• optkit: email subscriber management for Cloudflare Workers.

• vet: CASA Tier 2 / OWASP ASVS security scanner.
