Tiekai Guardian is an AI doctor for your servers. When your site goes down, slows to a crawl, or a service crashes, it connects, reads the logs, finds the cause, and repairs it only after you approve each step. FREE TO START - One-tap health check: load, disk, memory and failed services at a glance (SSH servers) - One-tap basic maintenance: restart failed services, clean up logs and caches, renew expiring SSL certificates. Each action waits for you to tap Run (no AI, no points) - No sign-up, no credit card SUBSCRIBE FOR THE AI DOCTOR - Describe the problem in your own words ("my site returns 502") and Guardian checks status and logs to find the root cause - Read-only diagnostics run automatically; anything that changes your server (restarts, deploys, config changes) always stops and asks you first - Colour-coded risk labels on every command: green read-only, amber write, red dangerous - A full audit log of what was proposed, approved, denied and executed - 24/7 monitoring for websites and cloud services, with alerts and a first AI diagnosis THREE PLANS, SAME FEATURES, DIFFERENT ALLOWANCES - Basic: 1,000 points per month, monitor 2 targets - Pro: 3,500 points per month, monitor 5 targets - Max: 12,000 points per month, monitor 20 targets Run out?
