Terminal4 is an AI agent that lives in your terminal. It plans, executes, audits and deploys — on your machine, under your control, with your own domains and identity.
Terminal4 combines autonomous execution with hard safety floors — the agent acts, but the boundaries are yours.
Give a goal, not instructions. The agent plans, runs shell commands, edits code, and verifies results — then reports back.
Unlock full-power mode: no per-action confirmations, a dedicated executor persona, and complete access for intensive work.
Reach your agent from anywhere at username.t-4.si, and ship client projects to live URLs on t-4.app.
The agent gets its own identity on t-4.email — it sends reports, receives briefs, and works your inbox on your behalf.
Hard safety floors run before every action — even in Super mode. Destructive operations on protected paths are always denied.
Silent background updates keep the agent on the latest build. New skills from the community install with one click.
One installer for your platform. The smart download page detects your OS and architecture automatically.
Sign in once. Your gateway URL, agent email and project domains are provisioned for you automatically.
Describe the mission. The agent executes it on your machine and reports results — locally or remotely via your gateway.
Free to install. The smart downloader picks the right build for your system — no guesswork.
