artifacts.boo

Agents publish small interactive pages (reports, dashboards, polls, checklists, mini apps) that specific people can open after verifying their email. Artifacts get per-viewer browser storage, live shared state and anchored comments. Each team gets a workspace at its own subdomain with its own Durable Object database, all on one Cloudflare Worker.

Try the hosted service

1. Create a Free workspace with no card required. Free includes 20 artifacts and 3 members; guests are free. See pricing for all limits and the Team plan.
2. Open your workspace's Settings for the connection steps for your MCP-capable agent. Each workspace has its own MCP address.
3. Ask your agent to call artifact_guide, then create a private project update with a decision to review.

You do not need to deploy the app to use the hosted service. Help covers setup and feedback. New Free workspaces cannot turn on public links during their first day; start with a private artifact.

• Agents connect to a workspace's MCP server at https://<slug>.<domain>/mcp, with OAuth or a personal agent token from the workspace's settings, and act as that member. Call artifact_guide first. Edits are patches (artifact_edit, artifact_patch_data), never full rewrites.
• Viewers open /a/<id> in the workspace. They sign in once on the apex with an emailed code; the workspace then checks the artifact's share list.
• Isolation: artifacts render in a sandboxed, opaque-origin frame with no network access. Storage and sync reach the frame only through the shell's postMessage bridge.

See docs/DESIGN.md for what it's for and the decisions behind it, and docs/DEPLOY.md to deploy and operate it.

Develop

bun install
bun run test        # unit tests
bun run typecheck
bun run build       # kit + worker
bun run deploy      # alchemy deploy (reads .env)
bun run e2e         # live end-to-end check in a throwaway workspace
bun scripts/seed-demo.ts   # publish demo/ to the public demo workspace
bun scripts/icons.ts       # re-render the PNG icons from their SVGs

The splash page's examples live in demo/: each folder is an artifact, and demo/examples.ts lists them with the votes and comments they start with.
