Browser automation CLI for AI agents - reliable element targeting through accessibility tree refs

browse-now

Browser automation CLI for AI agents. Control your real browser from the command line with reliable element targeting through accessibility tree refs.

Part of Nowledge Mem - Personal memory for AI agents.

Now a compiled binary. browse-now ships the Rust-built browse-now binary instead of a Python module. pip install browse-now downloads a platform wheel that contains the compiled CLI and puts browse-now on your PATH. No Python runtime requirement beyond pip, and no Python dependencies. It drives your browser through the Nowledge Mem Exchange extension over the local WebSocket bridge the Nowledge Mem app already serves. The command surface is unchanged.

Why browse-now?

• Low overhead: No tool definitions loaded into LLM context (unlike MCP)
• Reliable targeting: Uses accessibility tree refs (@e1, @e2) for high click reliability
• AI-agent optimized: Designed for the snapshot → click → repeat workflow
• Multi-browser support: Works with Chrome, Arc, Edge, and other Chromium browsers

Installation

pip install browse-now

The wheel bundles the compiled browse-now binary for your platform (macOS arm64/x86_64, Linux x86_64/aarch64, Windows x64). It must still run on the same machine as the Nowledge Mem app and the connected browser extension.

Prerequisites

1. Nowledge Memory Exchange Chrome extension installed and active
2. Nowledge Mem app running on the same machine (provides the local browser bridge)

Quick Start

# Navigate to a page
browse-now open https://example.com

# Get interactive elements with refs
browse-now snapshot -i
#   textbox "Search" [e1]
#   button "Submit" [e2]

# Click by ref
browse-now click @e2

# Fill input
browse-now fill @e1 "AI agents" --submit

# Show version
browse-now --version

Core Workflow

1. browse-now open <url>           # Open page (isolated agent tab)
2. browse-now snapshot -i          # Get refs [e1], [e2]...
3. browse-now click @e5            # Click by ref
4. browse-now fill @e3 "text"      # Fill by ref
5. (If page changed) → snapshot -i again

Local-only security model

browse-now talks to the browser bridge endpoints exposed by the Nowledge Mem app. Those endpoints are intentionally local-only: they are not exposed through Access Anywhere, Cloudflare tunnels, or other remote-access paths.

• browse-now must run on the same machine as the Nowledge Mem app
• the controlled browser must also be on that same machine with the Exchange extension active
• publishing to PyPI makes the CLI easier to install, but does not turn browser automation into a remote-access surface
