OmniTroops is the mobile cockpit for your self-hosted OmniTroops gateway — the multi-agent AI platform that runs on your own hardware, with your own models. Drive your fleet from anywhere: • CHAT WITH ANY AGENT — streamed responses, markdown, images, file diffs, and live plan cards, rendered natively. • GET PINGED WHEN IT MATTERS — push notifications when a long-running mission finishes, fails, or an agent has a question only you can answer. Tap the notification and land directly in that conversation. • YOUR WHOLE FLEET — switch between agents and teams, watch sub-agents spawn and report back, resume any session. • ZERO-CONFIG ON YOUR NETWORK — gateways on your LAN are discovered automatically (Bonjour). Away from home, connect through your own secure remote URL (Cloudflare Tunnel, Tailscale, or reverse proxy — wss:// TLS). • SPEAK YOUR MISSIONS — push-to-talk dictation straight into the composer. • ATTACH AND BROWSE — send photos to your agents and browse your gateway's documents and plans. • YOUR DATA STAYS YOURS — the app talks only to the gateway you point it at. No analytics, no tracking, no third-party data collection. OmniTroops requires a running OmniTroops gateway (free download at omnitroop.com). It is a companion app — bring your own fleet.
