一款包含了 Prompt管理，Skill管理，Agent管理的一站式AI工具箱，助你高效管理提示词，一键分发skills ，一站式管理Agent资产，并实现云同步，备份，版本管理 | An all-in-one AI toolbox for prompt, agent, and skills management. Reuse prompts, distribute skills with one click, manage agent assets, and support cloud sync, backup, and version control

PromptHub is a cross‑platform desktop application (built with Electron, React and Tailwind) that lets you store, version‑control and test the prompts and SKILL.md files you use with AI‑coding assistants (Claude Code, Cursor, Codex, etc.). All data lives on your computer by default, but you can sync it via WebDAV/S3 or a self‑hosted web version.

Key capabilities

  • Prompt manager – folders, tags, favourites, variable placeholders ({{var}}), full‑text search, markdown rendering and history/rollback.
  • Skill store – a built‑in catalogue of 20+ ready‑made AI‑coding “skills”, plus the ability to add custom sources (GitHub, local dirs, skills.sh). One‑click installs the skill into dozens of supported IDE/assistant platforms, either as a symlink (live edit) or a copy.
  • Rules workspace – centralised handling of rule files (.cursor/rules, .claude/CLAUDE.md, AGENTS.md, etc.) with version snapshots and import/export.
  • Project‑level workspaces – automatically scans a project’s .claude/skills, .agents/skills, skills, .gemini folders so you can keep project‑specific assets separate from your global library.
  • AI test & generation – run a prompt against multiple models (OpenAI, Anthropic, Gemini, Azure, custom endpoints) in parallel, compare results, and even generate new prompts or skill drafts with AI.
  • Versioning & backup – every edit creates a version; you can diff, roll back, or export a complete snapshot (.phub.gz). Backups can be stored locally, on WebDAV/S3, or in a self‑hosted PromptHub Web service.
  • Security – optional master‑password protects the app, with AES‑256‑GCM encryption for private folders (beta).
  • CLI – a command‑line interface for scripting bulk imports/exports, scanning, syncing and other admin tasks.

Who it’s for

  • Developers who use multiple AI‑coding assistants and want a single place to keep their prompts and skill definitions.
  • Teams that need to share and version‑control AI assets without relying on a cloud‑only service.
  • Power users who want to automate deployment of SKILL.md files to many tools at once.

How you get it

  • Pre‑built installers for Windows, macOS (Intel & Apple‑Silicon) and Linux (AppImage / .deb) are published on the GitHub releases page.
  • A Docker‑based self‑hosted web front‑end is also provided for browser‑only access or LAN‑only backups.

Roadmap highlights

  • Full plugin ecosystem, expanded MCP (Marketplace) management, tighter agent integration, and Cloudflare Workers deployment.

TL;DR – PromptHub is a local‑first, cross‑platform manager for AI‑coding prompts, SKILL.md files and related rule assets, with versioning, multi‑model testing, one‑click deployment to dozens of AI assistants, and optional cloud‑sync or self‑hosted web backup.
