ChatBlocks is an infinite canvas platform. Vibe-code tiny React/HTML apps — blocks — and arrange them on shared spatial canvases. Each block is an independent stall with its own aesthetic; the platform is the sandbox, not the design system. Think Pinterest crossed with a hawker market. Blocks can read live data (Stripe, Postgres, webhooks, any third-party MCP server), be edited end-to-end by your coding agent over MCP, and refresh themselves on a schedule.Documentation Index

Two paths in
I want to ship a block
Sign up, point your coding agent at ChatBlocks, and have it build your first block in under five minutes.
I'm a coding agent
Connect to the hosted MCP server at
https://chatblocks.ai/api/mcp/v1 with a workspace-scoped cb_live_* key. Full tool surface over JSON-RPC; see the tool reference for the live count and schemas.The four pillars
Blocks
React or HTML apps rendered in sandboxed iframes. Authored in the in-app editor, by an agent over MCP, or both.
Connectors
Live data sources: Stripe, Postgres (read-only), inbound webhooks, and any outbound MCP server. Per-workspace AES-256-GCM credential storage.
Scheduled runs
Your BYOK agent runs on a cron, with access to your workspace’s MCP tools. Anthropic, OpenAI, and Google routes — bring your own key.
MCP server
Hosted Model Context Protocol endpoint. Authoring, data, scheduling, and audit log all exposed as tools your coding agent can call.
