01 / Install

The installer checks the download’s checksum and installs gripui, with grip and gu as short aliases.

curl -fsSL https://gripui.com/install.sh | bash

irm https://gripui.com/install.ps1 | iex

macOS arm64 / x64 · Linux x64 · Windows x64. Firefox also needs geckodriver on your PATH.

02 / Activate your licence

Browser actions require a paid licence. Choose Solo Dev or Pro Runner, then use the key from your licence email:

gripui license activate <your-key>

Replace <your-key> with your key. Run gripui license status to check activation. See licence help for renewals and moving machines.

03 / Teach your agent

From your project directory, run:

gripui teach

This installs the skill for Claude Code, Codex, Gemini CLI, Copilot and Grok. Start a new agent session so it can discover the skill, then ask it to use gripui.

04 / Start a session

Ask your agent to attach a named profile for the job, open a public page, and read it with gripui hud. You can also try the commands yourself:

gripui attach work

gripui go https://example.com

gripui hud

Run one command at a time and read the result. For sites that require sign-in, use a human handoff. Start with only the accounts the task needs.

Prefer MCP?

gripui mcp exposes one tool over stdio. It uses the same commands, licence, profiles and browser session as the CLI.

claude mcp add gripui -- gripui mcp

For Codex, add this to ~/.codex/config.toml:

[mcp_servers.gripui]
command = "gripui"
args = ["mcp"]

For another MCP client, use gripui as the command and mcp as its argument. Ask the agent to attach a named profile before browsing, or pass an explicit profile in its calls.

Updating

Run the installer again. The next browser command upgrades the daemon while retaining its browser session; an active command finishes before replacement.
