What is it?

PromptHub keeps prompts, SKILL.md skill files and project-level AI coding assets in one local workspace. A skill can be installed into more than a dozen AI coding tools, including Claude Code, Cursor, Codex, Windsurf and Cline, either as a shared symlink or as an independent copy per platform.

Beyond distribution, it covers prompt version history with diffs and rollback, template variables written as {{variable}}, and side-by-side testing of one prompt across multiple models. Data stays on the user's machine by default, and it can sync through WebDAV or S3 or back up full snapshots to a self-hosted web instance.

The project is built with Electron, React and SQLite for macOS, Windows and Linux, and includes a separate command-line tool for scripting imports, exports and scans.
