Radius GTM brain

Radius is a macOS browser for developers to run coding agents alongside browser tabs, terminals and code review.

category

Agentic developer browser

market profile

  • text: Developers running parallel coding agents need to coordinate worktrees, terminal sessions and browser context.
  • text: Radius uses existing Claude Code, Codex and Cursor accounts rather than requiring another agent subscription.

personas

  • title: Software engineer using coding agents
    pains:
    • Switches between IDE, pull requests, docs and localhost while managing agents
    • Parallel worktrees and sessions lose context across windows
  • title: Technical founder building web products
    pains:
    • Wants multiple coding agents to work on separate tasks without constant window management
    • Needs quick access to diffs, terminals and live previews
  • title: Engineering lead evaluating developer tools
    pains:
    • Developers already pay for agent subscriptions
    • Wants clarity on where credentials and worktree data reside

icp

  • text: Mac-based software engineers and small product teams already using supported coding agents, especially on browser-heavy web development.
  • text: Teams experimenting with parallel agent tasks and Git worktrees; a company size or industry requirement is not stated.

message pillars

  • text: Unify browser and development work.
  • text: Keep agents, terminals and other work in tabs.
  • text: Organize concurrent work by project and worktree.

objections

  • objection: Do I need another agent subscription?
    response: Radius says it uses existing Claude, Codex or Cursor accounts without an additional Radius subscription; provider costs still apply.
  • objection: Where do credentials and agent state live?
    response: The site says sessions and keys are stored locally and agents authenticate with their providers directly; review this against your organization's policy.
  • objection: Can the whole team use it on any operating system?
    response: The current download supports macOS only, so assess platform coverage before rollout.

competitors

  • name: Cursor
    why: AI coding editor competes for the developer's primary agent workspace and is also a supported agent.
  • name: Arc
    why: Browser workspace alternative referenced in the founder's launch description.
