鐵鎧守護神

No laptop, server down, fix it NOW? Guardian links to your server with top-tier AI — rescue from one phone. Read-only auto-runs; risky commands need approval.

You're out, no laptop in sight, and a server goes down that has to be fixed right now to stay up? With Tiekai Guardian, no panic — the app connects directly to your server, powered by the most capable AI. One phone is your entire on-call setup.

Free forever. Bring your own AI key. An AI server doctor that lives in your pocket and works over SSH.

Tiekai Guardian connects your AI provider to your own servers and lets it do the boring, critical work: scheduled maintenance and emergency troubleshooting over a direct SSH session. Read-only diagnostics run on their own. Anything that changes your system stops and waits for you.

BUILT FOR PEOPLE WHO RUN SERVERS Developers, sysadmins, DevOps, self-hosters, homelab tinkerers, indie hackers, and anyone with a VPS on Linode, AWS, GCP, DigitalOcean, Hetzner, or a box under the desk.

BRING YOUR OWN KEY (BYOK)

• Use your own Anthropic Claude, OpenAI, Google Gemini, or any OpenAI-compatible endpoint.
• The app is free. You pay your AI provider directly, so there is no subscription and no markup.
• No ads. No in-app purchases. No telemetry games.

THE SAFETY MODEL IS THE WHOLE POINT

• Read-only diagnostics (df, top, journalctl, systemctl status, and friends) auto-run so you get answers fast.
• ANY write or dangerous command requires explicit, per-command human approval. Nothing destructive happens behind your back.
• A local risk classifier independently re-grades every command and always takes the higher risk rating.
• Full audit log of every command that was executed, when, and why.

THE AI STAYS IN ITS LANE Its job is fixed to maintenance and troubleshooting, not building features or rewriting your stack. It diagnoses, proposes, and waits.

YOUR SERVER, YOUR CONTROL

• SSH credentials and your API key are stored only in the iOS Keychain, on-device.
• Connections go device to your server and device to your AI provider, directly. No third-party relay sits in the middle.

ONE-TAP QUICK ACTIONS

• Health check
• Emergency troubleshoot
• Disk cleanup
• Security sweep

Add a server, point it at your AI key, and let Guardian handle the 3 a.m. pages and the weekly housekeeping. You stay in control of every keystroke that matters.
