Sol Browser

Sol Browser is a San Francisco startup (Y Combinator Fall 2025) building a browser designed to work as a developer's IDE. It lets engineers run multiple AI coding agents - Claude Code, Codex, Cursor - in parallel from browser tabs, alongside terminals, diff viewers, running apps, docs and pull requests. The company began as Inspector, an AI IDE that connected the browser to the codebase so agents could see the same visuals, elements and logs a developer sees, then expanded that idea into a full browser workspace. Founded by Quentin Romero Lauro and Michael Klikushin, it operates as Sandbox Technologies, Inc.
