Prefer not to subscribe? Buy Standard once for ¥45,000. It includes the same support and upgrades; there is no recurring bill. Choose Buy on the Standard plan above.

Standard includes the local server stack, up to 10 linked servers and 3 Macs, one-server-at-a-time diagnostics, AI diagnosis, KVM and power controls, and the audit log. Add a 10-pack if you need more device slots.

Full Fleet removes every limit and adds the many-at-once tools: Fleet Run, push to production, fleet security audits, cloud and SaaS boards, external AI control over MCP, iPhone remote control and team administration.

FrontierStack AI

FrontierStack includes free use of FrontierStack's AI servers for now, so you can run the AI Harness without supplying a provider key. The default Qwen3 engine runs through Enfour's AI Cloud. Availability, limits and pricing may change in the future.

Zero retention is required and attested on every response
Provider credentials and upstream endpoints remain on Enfour servers
Prompts are deterministically redacted before leaving your Mac
Strict Harness guard-rails, tool restrictions and action approvals remain enabled

FrontierStack AI is optional. You can instead bring your own key from a major AI platform or run a local model with Ollama, LM Studio, Apple Intelligence, or another compatible local engine.
