Hermes is a tool to own your data. It can parse exported data from different sources and collect them in a JSON, Obsidian flavoured markdown, or SQLite/remote Datasette format on your own computer.

Partially ✨Vibe coded✨ with Cursor, Claude Code and Cline

Other

Most API data is cached locally just to be a good API citizen

• Initial Steam import might take a while, you need to restart every few hours
• OMDB has a 1k/day limit, so bigger lists may take a few days to fully process
