Pilion

A desktop browser for ACP agents — connect yours locally or over SSH, and let it drive the browser through MCP: approvals, takeover, session resume.

Browse, chat, collaborate — in three panes

Manage tabs and work history on the left, browse normally in the middle, talk to an agent on the right. Via MCP, the browser hands your tab to the agent: browser_snapshot, browser_screenshot, navigate, click, type.

Any ACP agent, locally

Claude Code, Codex, Gemini CLI, Grok Build, OpenCode, Pi, Orca, Blade — locally installed agents work out of the box, running foreground or silently in the background.

Or run your agent remotely

Connect to agents on a remote server over SSH with exactly the same experience — heavy lifting stays on the server, interaction stays in the browser.

Approve first, take over anytime

Every sensitive agent action goes through inline approval first: inspect the exact step, approve, edit or reject. Sessions can be resumed, and you can take over anytime.

Inline approval: confirm the agent's next action in page context. 点击放大

Skill recording: you show it once

Record a web flow once in the browser; the agent distills it into a reusable skill. Replays go through the same tool path as the agent, with a single confirmation on first replay per task.

Record

You perform the flow once, as a human.

Narrow windows & background mode

Collapse to two panes when the window narrows, and let “background” windows run agent tasks silently without interrupting your work.

Install notes

The macOS build is signed and notarized by Apple — just open it. Windows and Linux builds aren't signed yet; see the notes for yours.

Drag to Applications and open

  1. Open the dmg and drag Pilion to Applications
  2. Open Pilion from Applications

Signed with a Developer ID and notarized by Apple, so macOS won't say it “can't verify the developer”. Pick arm64 for Apple silicon, x64 for Intel.

Getting past SmartScreen

  1. Run the downloaded Pilion-<version>-win-x64.exe
  2. Click “More info” in the SmartScreen dialog
  3. Click “Run anyway” to continue

The exe isn't signed yet, so Windows SmartScreen will warn — that's expected.

AppImage / deb

  1. Download the AppImage or deb
  2. AppImage needs the executable bit set first
  3. Install the deb with your package manager
chmod +x Pilion-linux-x86_64.AppImage

Both AppImage and deb are unsigned; each file on the Releases page lists its SHA-256 if you want to verify it first.
