Built by the founder. Beta-tested by real users. Enter a task and Y0 plans, browses, codes, connects, and executes it on a machine of its own. Currently under maintenance — returning.

[ 01 ]What Y0 is
Task in, work out
A clean frontend where you enter a task in plain language. Y0 plans it, executes it, and shows its work — every step traced, nothing hidden.
- ↳Plain-language tasks
- ↳Autonomous planning
- ↳Full execution traces
- ↳Live progress
A machine per chat
Every chat gets its own configured virtual machine — and a new chat in the same session gets a fresh one. Isolated, disposable, yours for the run.
- ↳Dedicated VM per chat
- ↳Fresh machine per new chat
- ↳Built-in browser
- ↳Isolated workspaces
Connected to everything
Thousands of MCP server connections plus automations reaching 10,000,000+ apps. Crons for the work that repeats; one-off runs for the work that doesn't.
- ↳1,000s of MCP connections
- ↳10,000,000+ app automations
- ↳Scheduled crons
- ↳Webhooks & triggers
Built to research and build
Multiple web-search APIs, paper search, company search, legal search, browsing, and scraping — alongside full coding and development capability.
- ↳Web, paper & company search
- ↳Legal search
- ↳Browsing & scraping
- ↳Coding & development
[ 02 ]The engine room
Y0 routes each step across frontier model tiers — Opus-class for hard reasoning, Sonnet-class for the long middle, Haiku-class for the fast edges — backed by a research stack of web, paper, company, and legal search.

[ 03 ]Where it stands
Y0 shipped as a free beta and earned a working cohort of real users running real tasks. That is the only proof we trust — not a waitlist, not a demo video.
It is currently offline for maintenance while we rebuild the foundation underneath it — this site is the first brick. When Y0 returns, the people on the early-access list hear first.
