vibe-replay

Turn Claude Code and Cursor sessions into shareable, interactive replays.

The problem

AI agents write code in long, complex sessions — dozens of tool calls, hundreds of file edits, thousands of lines of reasoning. When the session ends, all that context disappears. Your PR diff shows what changed, but reviewers can't see why. Teammates can't learn from your prompting. You can't even replay your own session next week.

The fix

One command. One self-contained HTML file. Every prompt, every thought, every tool call — animated and interactive.

npx vibe-replay

Also available as a Claude Code plugin — your agent generates replays automatically during PR creation.

What You Get

All your sessions, one place

Launch with npx vibe-replay -d and see every Claude Code and Cursor session across all projects — with activity heatmaps, cost totals, and project analytics.

Watch the full replay

Pick a session and step through every prompt, thinking block, tool call, and code diff with animated playback. Three view modes — All, Compact, and Custom.

Deep insights for every session

Auto-generated analytics: token burn & cost over time, context window usage, cache hit rates, tool call distribution, model breakdown, and per-turn breakdowns.

Your AI coding wrapped

GitHub-style activity heatmap, streaks, weekly trends, top projects, model usage, and cost tracking across all your sessions. See how your coding patterns evolve over time.

Claude Code Plugin

vibe-replay is also available as a Claude Code plugin. Once installed, your agent learns how to generate replays autonomously — it can find the current session, produce GitHub-ready artifacts, and embed them in PRs, all without you running any CLI commands.

What the plugin gives your agent

• Auto-discover sessions — finds the current session's JSONL file via $CLAUDE_SESSION_ID
• Generate PR artifacts — markdown summary + animated GIF + SVG, ready for PR descriptions
• Generate HTML replays — self-contained interactive replay files
• PR workflow integration — agent automatically embeds replay context when you create PRs

Install (recommended)

/plugin marketplace add tuo-lei/vibe-replay
/plugin install vibe-replay@vibe-replay

Manual install (single file)

If you prefer not to install the full plugin:

mkdir -p ~/.claude/skills/replay
curl -o ~/.claude/skills/replay/SKILL.md \
  https://raw.githubusercontent.com/tuo-lei/vibe-replay/main/skills/replay/SKILL.md

Usage examples

# Slash command — generate a replay of the current session
/vibe-replay:replay

# Natural language — agent auto-triggers during PR creation
"Create a PR with session replay"
"Create a PR for this change, include an animated GIF of the session"

# Direct replay
"Generate an interactive replay of this session and open it"

Features

• Zero config — one command, no setup, no account. Works instantly with existing sessions
• Single HTML file — self-contained, works offline, zero external requests. Drop it in Slack, email it, open it anywhere
• Claude Code + Cursor — both providers auto-discovered, including multi-file and resumed sessions
• Share & export — GitHub Gist, animated SVG, GIF, markdown summary, or cloud upload. Secret redaction built in
• Sub-agent visualization — see delegated tool calls and sub-agent trees rendered inline
• Comments — leave notes on any scene. Comments persist in the HTML and travel with the replay

How It Works

AI session files  →  vibe-replay  →  self-contained HTML
(Claude Code,        (discover,       (animated viewer,
 Cursor)              parse,           insights panel,
                      redact,          offline-ready,
                      transform)       shareable)

The CLI auto-discovers sessions on your machine, parses conversation data from all sources, and packages everything into a pre-built React viewer — one HTML file that works anywhere.

After generation:

• Open in Editor — annotate scenes, get AI feedback, export to multiple formats
• Quick preview — open in browser instantly
• Publish to Gist — shareable link on vibe-replay.com
• Export for GitHub — markdown + animated SVG for PRs

Use Cases

• Vibe coding review — replay your AI-assisted coding sessions to spot prompting patterns and improve your workflow
• Team knowledge sharing — show teammates how you built something, not just the final diff
• PR context — attach a replay link to PRs so reviewers understand the reasoning behind changes
• Teaching & onboarding — create replayable walkthroughs of real coding sessions for documentation or training
• Cost tracking — see exactly how many tokens each session burns, track costs across projects

Security & Privacy

• Self-contained HTML — generated replay files embed all assets inline. When opened from disk they make zero external requests — works offline, behind firewalls, on an airplane. (Gist/cloud-backed replays fetch data from GitHub or vibe-replay API on load)
• Secret redaction — API keys, tokens, PEM keys, and sensitive paths are automatically detected and redacted before generation
• Local by default — vibe-replay reads session files from your machine and generates a local HTML file. Data only leaves your machine when you explicitly publish (Gist or cloud upload), or if you log in — in which case aggregated session insights (counts, durations, costs — no conversation content) sync daily to the cloud
• No wrappers, no proxies — vibe-replay does not modify, intercept, or wrap Claude Code or Cursor. It reads existing session logs after the fact

Development

git clone https://github.com/tuo-lei/vibe-replay.git
cd vibe-replay
pnpm install
pnpm dev              # Viewer (Vite HMR) + CLI (auto-restart) — full HMR
pnpm dev:website      # Website (Astro HMR) + Viewer (Vite HMR)

CLI usage requires Node.js >= 20. The website package uses Astro 6 and requires Node.js >= 22.12.0. When nvm is available, website scripts will try nvm use from website/.nvmrc automatically.
