Radius Browser
Radius is a Chromium-based browser that functions as an IDE-like workspace, letting developers run coding agents like Claude Code, Codex, or Cursor in parallel alongside PRs, docs, terminals, and localhost servers. It automatically organizes worktrees into tab groups per project and operates local-first, storing agent state and credentials on the user's machine. The browser is free to use with existing agent subscriptions and currently supports macOS on Apple Silicon or Intel chips.

Problem
Developers often juggle multiple coding agents, pull requests, documentation, terminals, and localhost servers across separate windows and tools, fragmenting context and slowing workflows. Existing browsers and IDEs do not natively support running multiple agent sessions side by side with project-related resources in a cohesive workspace.
Solution
Radius is a Chromium-based browser designed as an IDE-like environment where developers can run coding agents in parallel alongside their PRs, docs, terminals, and localhost servers. It automatically creates new spaces for different projects and organizes worktrees into tab groups, keeping all project context in one place. The browser is local-first, meaning worktrees, sessions, and agent state live on the user's machine, and all credentials are stored locally. Radius works with existing Claude Code, Codex, or Cursor subscriptions, adding no additional cost or complexity for developers already using these agents.
Target Audience
Primary users are software developers who actively use coding agents like Claude Code, Codex, or Cursor and need a unified workspace to manage parallel agent sessions, code reviews, and project resources. The current version is designed specifically for macOS users on Apple Silicon or Intel chips.
