claudebin: share and embed Claude Code sessions

February 2026

Claude Code sessions are high-value artifacts that live and die in the terminal. You spend an hour debugging a race condition with an agent, arrive at a clean solution, and then… it’s gone. The JSONL files in ~/.claude/projects/ aren’t something you can easily share with a colleague or link in a PR.

claudebin is the “share button” for Claude Code.

/claudebin:share

The plugin authenticates via GitHub OAuth, extracts the current session, and returns a shareable, embeddable web URL. Full fidelity: prompts, responses, tool calls, bash outputs, and file edits are all preserved with syntax highlighting and structured formatting.

The Technical Archaeology

Building claudebin required reverse-engineering how Claude Code manages local state. Sessions aren’t stored with human-readable names; they’re normalized project paths.

I found that /Users/vlad/projects/my-app maps to -Users-vlad-projects-my-app in the filesystem. Every non-alphanumeric character is a dash. Inside those folders, claudebin has to filter out ephemeral agent-* sub-sessions and pick the correct default.jsonl by mtime.

This is the “messy middle” of building for agentic tools. claudebin handles the project path normalization (Regex), file discovery, and memory-safe JSONL parsing so you don’t have to.

Embedding & Resuming

Embed Everywhere: select a message range and drop it into a blog post or documentation. The embed renders the conversation exactly as it appeared in the terminal.

Resumable Sessions: Every shared thread includes a command to resume it locally. See a cool approach? One command, and you’re picking up where the original author left off in your own local terminal.

Architecture

  • Web App: Next.js, Supabase, Vercel. Handles rendering, search, and the embed API.
  • MCP Server: A Node.js plugin that Claude Code pipes JSON-RPC to over stdio.
  • Title Generation: An LLM pipeline analyzes the first few messages to generate a relevant, searchable title.
