// pro replays your prompts overnight. tells you what to switch. ↓
Every Pro row is automation we built on the free primitives. You can DIY every one of them with ato dispatch, crontab, and your own LLM prompts — Pro buys you the button. Same model as GitLab, Sentry, Supabase.
If you've ever set a cron job to re-run your eval suite and Slack you when scores drop, you've built half of ATO Pro by hand. Here's what we ship.
methodology schedule create — pick a methodology, pick a cron, get a fresh Welch-t + 95% CI report on every wake. No bash, no crontab -e, no parsing JSON.
Free DIY: crontab + ato methodology run + a wrapper script.
methodology diagnose)Failed regression on Friday? Pro spawns a 3-LLM diagnose war-room over the weekend, proposes a concrete agent change (prompt, model, tool list), runs the A/B, and tells you which version won. Monday morning you have a verdict instead of a backlog.
Free DIY: 3 ato dispatch calls + your own merging prompts + a follow-up methodology run.
Every dispatch from every machine you use streams to ato-cloud (30-day retention). When tool success rate drops 17pp after a model swap, you get an alert — not a six-week-late realization. Cross-device by design: your laptop's evals and the CI box's are in one ledger.
Free DIY: nothing, this needs a server you'd have to run yourself.
When methodology diagnose finds the new version beats baseline at p<0.05, Pro opens the PR for you — agent file change, methodology results in the PR body, before/after numbers. When it loses, you get a revert PR instead.
Free DIY: GitHub API + parsing methodology JSON + churning out the PR body.
Run a methodology on your laptop at 3pm. Open ATO on the desktop at home, the run's there. Schedule an evaluator to fire nightly — Pro runs it in the cloud even when your laptop's closed. Your free tier still does everything locally; Pro just keeps the lights on while you're asleep.
Free DIY: sync a SQLite file across machines + run a self-hosted scheduler.
You can already use any provider as a judge with your own API key (free tier). Pro adds a hosted judge endpoint with retry, cache, rate-limit handling, and a managed prompt library — so your overnight evals don't crash on a transient 429.
Free DIY: ato dispatch with your own judge prompt + retry wrapper.
Team workspaces (shared agents + skills + methodologies, encrypted provider key store) live on the $49/mo Team tier. See the full tier table on the homepage →
Everything in Free, plus the six automations above.

Because the free tier needs you to be at your laptop. Pro is what runs while you sleep, alerts you on a real regression, and opens the fix PR. Same shape as Sentry free vs. Sentry paid: the SDK is free; the cron job, the alert routing, and the retention live in the paid plan.
Dispatch + compare across runtimes. War-rooms, sessions, replay, receipts. ato review with tool calls. The full methodology runner (Welch t + 95% CI). The MCP server with 27 tools. Tauri desktop, embedded terminal, skills marketplace, agent wizard. Local-first, MIT, bring your own keys. None of that moves to Pro — we don't even reserve the right to.
API keys never leave your desktop — even on Pro. Prompts and responses get encrypted at rest before they go to cloud retention; we use envelope encryption with a key only your desktop holds. See Privacy and the grounding architecture for the full story.
Adapter pattern is on the roadmap — every dispatch already emits a structured event internally; the missing piece is the output layer to common collectors. If you want to be the first design partner on that, open an issue and we'll talk shape.
Team is $49/mo — multi-user shared workspaces, the encrypted provider-key store, cron usage poller. Enterprise (SSO, audit retention, custom SLA) is in the roadmap; talk to us if you need it now.
One button in Settings → Cloud. We don't gate the cancel behind a sales conversation.
Free tier first — you don't pay anything until you decide the automations are worth $29. No credit card to install.
