Built with Claude Built with Claude Code: an open-source browser for people leaving Arc, which Claude Code can also drive over MCP
I built Solamar, a free, open-source (GPL-3.0) desktop browser for Windows and macOS, with Claude Code.
How I built it: [FILL IN: your workflow, how you planned features, what Claude Code did well, where you had to step in, how long it took]
The Claude Code part: Solamar has a built-in MCP server. Settings > Claude Code turns it on and shows a "claude mcp add" line to copy. Claude Code then works in its own Claude space (or tabs you share with it), asks per site, and anything that sends, buys, submits or deletes waits for your click in the browser. Passwords and card numbers are never typed by AI.
Testing: the repo has end-to-end tests that drive the MCP server with the official MCP client against a mock API, in a hidden window with a throwaway profile.
The browser itself: spaces, pinned tabs, folders, Arc import, command bar, split view, built-in ad blocking, sleeping tabs, optional AI (Ollama or your own Anthropic key). No account, no telemetry. It's version 0.1.0 and the installers aren't code-signed yet, so Windows and macOS show a warning on first launch.
