Draw pipelines on a visual graph
Plan with Claude, fan out to Claude Code and Codex, gate the merge behind a human checkpoint.
Branch the graph, run both sides at once, and pipe the outputs into a review node.
Find the node that broke and what it received — without rerunning the whole pipeline.
Claude, Codex & APIs, PTY-streamed
A planner on Claude, a coder on Codex, a cheap reviewer on @fast — pinned per node.
True PTY streaming from each CLI session, character by character.
No copy-paste between terminals — edges carry the artifacts.
Filesystem-based, versioned with your repo
Agents are markdown with frontmatter — diff the persona, comment, merge.
Drop the same .claude/agents file into any repo; the canvas picks it up.
git restore the file. That is the whole rollback story.
Two-way JSON Canvas sync
Design in your vault, then open the same .canvas file in Futsu and run it.
Plain JSON Canvas files version like everything else you write.
Round-trips are lossless — unknown fields survive, and the diff proves it.
AES-GCM keys, user & workspace scopes
Workspace-scoped secrets decrypt per run; plaintext never lands on disk.
User-scoped entries stay yours, even on shared canvases.
Scan the repo, find real keys, import them into ciphertext in one click.
One balance, every model
No card and console per provider — multipliers are published, the meter is live.
The run halts mid-pipeline when the ceiling is hit — not in tomorrow’s report.
Tokens never expire, and bigger packs auto-unlock lower rates.
Futsu is in early access. We don't have customer quotes yet — and we will never invent them. Here is what we can show you instead, today.
A testimonial says “trust them”. An artifact says “check yourself”. We prefer the second kind.
Download an actual .futsu/runs/ artifact — state.json + events.ndjson with the engine's real schema — and grep it before you sign up. futsu-sample-run.tar.gz (2 KB)
Early access is instant — no waitlist, no sales call. The fastest review is the one you write yourself after your first run tonight.
No support portal theatre — the builder reads every mail at hello@futsu.cloud. Broken things get fixed; promises get kept or withdrawn.
I run coding agents all day, and I was tired of babysitting five terminals with no pipeline between them. Futsu is the canvas I wanted: agents wired together, every run a folder I can grep. It's early — the canvas, runners, live streaming, the vault and cost caps work today; SSO and SLAs don't exist yet. If you try it and something breaks, tell me. That's what early access is for.
