What you get before you pay anything
The free tier is the product with one flow live, not a countdown. These are the three things that decide whether the first afternoon goes anywhere.
The canvas rejects the flow the runtime would
Unknown blocks, mismatched ports and cycles fail on the graph rather than at run time. The validator drawing your flow is the one the API versions it with, so a canvas that accepts it is a deploy that works.
One live flow on the free tier, indefinitely
No card, no trial window, and the deploy cap is the only thing that separates it from Starter. Delete a deployment and the slot comes back the same second.
MCP is a block, not an integration project
Point the block at any Model Context Protocol server over HTTPS and its tools are a step in your flow. Credentials stay in the secret store — the graph the composer reads holds a reference, never a token.
Where this sits on the ladder
Free while it is a weekend project, Starter once it has users. Both run the composer and the runtime in full.
Your first flow is fifteen minutes away
Four blocks, one deploy, a live URL on Cloudflare’s edge. Nothing to stand up first, and nothing to take down if you change your mind.
Free tier, no card, no expiry.
