Stop paying for the same AI mistake twice.

One self-serve paid path for solo operators. Teams start with workflow scope so shared enforcement is mapped before checkout.

Free
$0
Block repeated mistakes daily. Forever free for solo devs.
  • 5 feedback captures/day (25 total) — enough to see the value
  • Up to 3 active prevention rules
  • All MCP integrations (Claude Code, Cursor, Codex, Gemini, Amp)
  • PreToolUse hook blocking with built-in safety checks
  • Runs 100% local — no account, no signup, no data leaves your machine
Install free
Pro
$19/mo
Don't buy a tool — buy hosted sync + compatibility insurance. The free CLI runs your gates locally, but Pro is what we operate for you: secure SQLite sync across all your machines (saving you from managing database migrations manually across developer boxes) and active adapter maintenance to stay compatible with weekly breaking updates in Claude Code, Cursor, and Cline.
  • Hosted lesson sync — corrections follow you across machines, no manual export
  • Managed adapter matrix — we track runtime changes in Claude Code, Cursor, Codex, Gemini, Amp so you don't
  • Hosted dashboard — see every blocked action, every rule that fired, without running your own server
  • Unlimited prevention rules — free caps at 3 auto-promoted rules
  • DPO + HuggingFace export — training data from your real corrections
  • Auto-connect — new agent surfaces appear automatically after setup
  • 7-day refund window. Cancel anytime.

Enterprise
Custom / scoped after intake
Shared enforcement for the whole team and regulated workflows. One engineer's save protects every agent.
  • Everything in Pro, for every developer and agent
  • Shared lesson database — one engineer's fix protects every agent on the team
  • Org dashboard — visibility across all agent surfaces and developers
  • Dialogflow CX fulfillment guard — put ThumbGate's pre-action gate in front of your Dialogflow CX webhook fulfillment, in your own GCP tenant, so risky or repeat turns are blocked before they touch a DB, CRM, or billing system (white-glove design-partner pilot)
  • Vertex AI / VPC gating — route agent checks through Gemini in your own Google Cloud project (npx thumbgate setup-vertex)
  • Regulatory gate templates — legal intake, financial compliance, healthcare
  • Custom policy layers, compliance audit export, approval boundaries, SSO, and dedicated onboarding with SLA
  • Rollout starts only after workflow and proof review are explicit

Custom pricing, scoped through intake so the workflow is explicit before checkout.

Questions

What does Pro add over the free CLI?
Free gives you 5 captures/day and 3 active rules, running entirely on your machine. Pro is the hosted layer: unlimited captures, unlimited rules, lesson sync across machines, a dashboard without self-hosting, managed adapter updates, and DPO export. You're paying for infrastructure we run, not features we hide.
Why not just use an enterprise AI control plane?
Enterprise control planes govern agents from a server-side gateway, sold to platform teams on a Fortune-500 timeline. ThumbGate runs local-first, in the PreToolUse hook on your machine, and ships enforcement for the coding agents developers actually use today — Claude Code, Cursor, Codex, Gemini, Amp, Cline, OpenCode — with an npm install and minutes to value, not a procurement cycle.
Does ThumbGate send my code to the cloud?
No. The CLI is local-first and no source code leaves your machine. Pro and Enterprise add hosted sync for dashboards and shared lessons, but your code stays local.
When should I pick Enterprise over Pro?
When one engineer's correction should protect the whole team. Enterprise shares the lesson database across the org so a fix in one repo prevents the same mistake in every repo.
Can I cancel anytime?
Yes. Pro and Enterprise are month-to-month with a 7-day refund window on the first charge. Cancel from the billing portal and your subscription ends at the period close.
What happens if I stop paying?
You keep the free CLI with 5-rule cap. Your existing rules and captures stay on your machine. You lose dashboard access, lesson search, exports, and auto-connect.
