There is no in-app purchase and no subscription. - This release focuses on SSH servers. - Read-only diagnostics still run automatically; every write action still requires your per-command approval. - Clearer connection error messages, with troubleshooting hints shown in the session. - Stability and interface fixes.

- Now completely free: every maintenance capability (including restart and redeploy with your approval) is free, and in-app purchases have been removed. - AI is performed through Tiekai's secure gateway, so you no longer need to bring your own AI key. - Every write action still requires per-command approval; dangerous commands are clearly flagged. - Stability improvements.

Major update: Guardian is now BYOK and fully free. - Bring your own AI key: Anthropic Claude, OpenAI, Google Gemini, or any OpenAI-compatible endpoint. - Now completely free. You pay your AI provider directly. No subscription. - Your key and SSH credentials are stored only in the iOS Keychain, on-device. - New multi-language interface. - More reliable SSH connectivity across networks, with automatic port fallback. - Smarter auto-detection of read-only commands so safe diagnostics run faster. - Redesigned chat with syntax highlighting and clear diffs for proposed changes. As always: read-only diagnostics auto-run, every risky command needs your approval, dual risk gating re-grades each command, and every executed command is logged. Thanks for running servers with us.
