I originally built it for demos. But people have been using it for knowledge sharing, teaching, documentation, and even debugging sandboxed agent workflows in the cloud. Pretty cool to learn about these use cases.

Since then: Cursor and Codex CLI support, Docker, --watch live mode, custom redaction, and two new ways to use it:

- Web UI, drag and drop a session file, no install needed: https://es617.dev/claude-replay/

- Local editor, run claude-replay to launch a full editor in your browser: browse sessions, edit prompts, exclude turns, add bookmarks, live preview

The output is still a single self-contained HTML file — step through prompts, tool calls, and reasoning. Zero dependencies, works on mobile, embeddable via iframe.
