1Password for Agents lets supported AI agents sign in to your accounts without ever seeing your passwords. When an agent hits a login, it asks 1Password.

Termi is a 3D room where your real coding agents (Claude Code, Codex, Gemini, OpenCode and more) work at their own desks. You watch every file read, command and edit live, not a scrolling log.

A boss agent splits one goal across your team. Deleted agents go to a trash. Now on macOS, Windows and Linux.

Agent Hunt is a live leaderboard of the tools AI agents actually use. Every place is earned by real calls agents make through Monid.
