Everything you need.
Nothing you don't.

Cyphir is built for developers who use AI agents seriously. Every feature is purpose-built for the command and control of autonomous coding workflows.

▶
REMOTE SESSION CONTROL
Start, monitor, and stop AI coding sessions from your phone. Choose your working directory, select your tool, and dispatch — from anywhere.

TOOL APPROVAL ENGINE
Set approval policies by pattern. Shell commands, file writes, network requests — Cyphir intercepts them and waits for your decision before anything executes.
▣
MULTI-MACHINE DASHBOARD
All your connected computers in one view. See what's running, switch machines instantly, and track last-active times across your full setup.
⌕
SESSION HISTORY SEARCH
Every session is stored and searchable. Full-text search across all your AI agent conversations — find any file edit, any command, any result.
↯
OFFLINE COMMAND QUEUE
Issue commands even when your computer is temporarily offline. Cyphir queues them locally and delivers automatically when the connection is restored.
⚿
END-TO-END ENCRYPTED
All connections are TLS-encrypted. Authentication is JWT-based with token invalidation. Secured by Veridian Shield™.
