ShareBit moves coding-agent output from your terminal into a browser without making it public. Pair an agent once, then ask it to share a plan, log, JSON response, code review, or Markdown report. Review the preview, approve it, and get a private link that expires in 30 minutes by default (up to 24 hours). It has a deliberately small MCP/API surface: create a share, list active shares, and read one back. No public mode, no ads, and no tracking pixels.
