Redmine Claude Syncer

Redmine Claude Syncer

A Ruby application that archives your Claude history in Redmine as a complete, browsable backup. It imports two things into the same Redmine project:

• Claude.ai conversations — from your account export ZIP (chats and Projects)
• Claude Code sessions — your local agentic coding sessions (the ~/.claude/projects transcripts)

Each conversation/session becomes a Redmine issue with every message as a note, so even after Claude Code compacts its context the full history lives safely in Redmine. Built to be run repeatedly (e.g. weekly): it's incremental and only adds what's new.

Features

• Imports both Claude.ai conversations and Claude Code coding sessions as a complete backup
• Renders the full message content as notes: text, thinking, tool calls and tool results
• Uploads all attachments and artifacts: user documents, Claude artifacts, created files (final version after edits), inline code blocks, and oversized blocks as files
• Imports Claude Projects (description, custom instructions and knowledge docs); coding sessions also attach the raw .jsonl transcript for full fidelity
• Tags issues by source for easy filtering: claude/web, coding-session/claude-code/, claude/project
• Sets issue start_date and leads each note with its original timestamp (Redmine can't backdate created_on)
• Creates issues oldest-first so issue IDs follow the conversation timeline
• Supersedes partial older imports: creates a complete new issue and closes (never deletes) the old one
• Idempotent: tracks conversations by content version and attachments by key, so re-runs don't duplicate
• Tracks conversation, attachment and project state in SQLite
• Handles retries and error recovery, skipping (and logging) any item that fails

Requirements

• Ruby 4.0 or later
• Redmine instance with API access, plus:
  • the redmine_tags plugin (for source tags)
  • the Start date standard f
