Darnly

Darnly is a free Chrome extension for people who build apps with AI coding agents. When something on the page looks wrong, press one key, click the broken part and type what you expected. Darnly writes a report into your project's .darnly/inbox/ folder: a screenshot with the broken part boxed in red, the element's details, the page address, and console errors and failed requests from the last 60 seconds. Then tell Claude Code, Codex or Cursor "fix my bugs". Code in the cloud? An optional private inbox and MCP server let your agent pick bugs up from there. No account needed, and passwords, tokens and API keys are hidden before anything is saved. There's also a free Mac app.
