Herdr Browser

terminal-browser is a command-line browser that renders Chromium inside a terminal window. It uses terminal graphics protocols such as Kitty to display Chromium's GPU-rendered pixels, captures mouse, keyboard, and operating-system input, and sends synthetic events back to Chromium. Its outer interface is built with a Rust graphics engine and a custom React renderer, with the browser content and interface drawn on a shared canvas. The CLI launches and opens URLs, supports split-pane display, lists open browser instances, and provides an agent-browser-compatible action interface for coding-agent control. It can route network requests through a remote server over SSH, allowing previews of sites running on remote machines. The project provides installation instructions for macOS and Linux and lists support for terminals including Ghostty, Kitty, cmux, and VS Code.

Browser Use Pi is a TypeScript web agent built on Pi Mono. It combines a persistent V8 REPL with raw Chrome DevTools Protocol control: the agent writes JavaScript, uses accessibility-tree data and screenshots, and builds browser helpers as needed. It supports persistent sessions, saved logins, workspaces, streaming, hooks, typed results, follow-up tasks, and cloud browsers or a user's own Chrome; runs can be limited by steps, time, or cost, with partial work retained. Interaction highlights, recordings, and GIF exports can show the agent's work. It is distributed as the @browser_use/pi package for Node 22.19+ or Bun 1.3.14+, and its quickstart uses Browser Use Cloud without requiring a local Chrome installation.

herdr is a terminal multiplexer and persistent runtime for coding agents, developed as a Rust binary. It runs a background server that keeps agent terminals and sessions available across terminal disconnections, SSH reconnections, network loss, lid closure, and machine restarts; users can reattach from another terminal and use tmux-style keyboard controls or mouse interactions to split, move, and manage panes. Each pane is marked working, blocked, or idle, and agents can control herdr through its CLI and socket API to spawn panes, prompt other agents, and wait for an agent that is blocked. It hosts existing tools such as Claude Code, Codex, Cursor, OpenCode, and Grok without wrapping or replacing them, and supports plugins for extending panes and workflows. The project provides installation scripts and package-manager installation, documents remote use and session state, and is licensed under the Apache License 2.0.

Herdr GPUI is a native Rust/GPUI desktop client for a separately installed Herdr daemon. It displays the daemon's terminal sessions, split panes, workspaces, Git worktrees, and agent activity without running another terminal emulator or wrapping the TUI. The daemon owns terminal processes and session state. Herdr GPUI connects to its local or saved remote daemon through the Herdr client socket, receives binary protocol frames and surface patches, renders the terminal surfaces, and sends semantic input back; closing the GUI leaves the daemon and its sessions running. The project is distributed from the repository as a signed, notarized macOS app through Homebrew, with additional Linux packages, experimental Windows builds, Nix support, and source-build instructions. The daemon must be installed separately. It is licensed under Apache-2.0.

Lightpanda Browser is a headless browser built from scratch in Zig for AI agents and web automation. It is not based on Chromium, Blink, or WebKit; its implementation includes an HTML parser, V8 JavaScript support, a DOM tree and APIs, network loading, cookies, form input, proxy support, network interception, and optional robots.txt compliance. It can dump pages as HTML, Markdown, PNG, or PDF, or expose a Chrome DevTools Protocol and WebDriver BiDi server for clients such as Puppeteer and Playwright. Its native agent mode uses an LLM to navigate pages, click through flows, fill forms, and extract structured data. Sessions can be exported as deterministic, token-free PandaScript JavaScript and replayed without a model at runtime. The browser also provides an MCP server over stdio or HTTP, with isolated or shared browsing sessions for multiple agents. The project distributes nightly binaries for Linux and macOS, Docker images for Linux amd64 and arm64, and packages for Homebrew and the Arch User Repository. It can also be built from source with Zig and its V8, Libcurl, and html5ever dependencies.
