# 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.

## Products & services

- **Sol Browser** — A macOS browser (Apple Silicon and Intel) built to function as an IDE. Developers run multiple coding agents - Claude Code, Codex, Cursor - in parallel across browser tabs, alongside terminals and diff viewers. Tabs can be split, reordered and arranged, with 'groups' and 'spaces' for organizing git worktrees. Free to use.
- **Sol SDK** — Programmable primitives that let developers customize how tabs, agents and workspaces are organized inside Sol Browser.
- **Inspector** — The company's original product: an AI IDE for front-end development that connected the browser to the codebase. It offered DOM-aware screenshots that snap to elements, visual element selection linked to exact code locations, and terminal/DevTools output attached directly to agent chats - giving coding agents the same runtime context (visuals, elements, logs) a developer has. Launched November 2025; evolved into Sol Browser.
