About
One maintainer, no team, no investors.
Totally Lean is a free Lean Business Model Canvas tool that runs in your browser. Nine sections, drag-and-drop, version history, shareable URLs, a 90-second voiced pitch generator, three local AI agents, and a published file format. No account. No server. No marketing motion.
Who builds it
Viraf Sarkari. One maintainer. No team. No investors. The maker uses Totally Lean for his own work, then ships the rest of you the keys for free.
There is no startup behind this product. There is no investor deck. There is no growth target on a quarterly basis. The development cadence is "fix the thing that annoyed me yesterday, ship it when it's ready, ignore everything else."
Why local
The whole product runs in your browser. The canvas you write lives in your browser's local storage. The AI runs on your machine via WebGPU or your own Ollama daemon. None of it touches a server I operate.
This is not a marketing claim. There is no server I operate. The site you're reading is a Vercel-hosted static export with no API surface for canvas data. I have no way to read what you write because there is no place where what you write would be readable.
Why no account
Sign-ups are friction in service of a business model I don't have. If I asked for your email, what would I do with it?
I'm not running a CRM. I'm not running a sales motion. I'm not building toward an enterprise tier. I've never written a "thanks for signing up!" email and I never want to.
What's stable
The .leancanvas file format is documented at /file-format. JSON Schema published. Versioned. If Totally Lean disappears tomorrow, your canvas opens in any text editor as plain JSON. You don't need me, this domain, or this tool to read what you wrote.
What you can ask for
Feature requests, bug reports, and editorial PRs land at github.com/viraf-pro/totally-lean. I read every issue. I sometimes go two weeks without responding. I will respond.
If you've used a Lean Canvas in a real business and want to write a worked example for /lean-canvas/examples, file a PR. Editorial commentary welcome. Real businesses preferred over hypotheticals.
What to expect
The roadmap is whatever annoyed me on a recent Tuesday. The release cadence is irregular. The bug-fix latency is short. The marketing budget is zero. The privacy posture is the only thing that's never going to change.
If that's reassuring, you're in the right place. If that worries you, Canvanizer and Strategyzer are also good tools.
