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

What it solves

PromptHub is a local-first workbench designed to centralize the management of prompts, skills (SKILL.md files), and AI programming assets. It eliminates the need to manually copy-paste assets across different AI coding tools and provides a structured way to version, test, and sync these assets across devices.

How it works

The application operates as a desktop client (built with Electron, React, and SQLite) that stores data locally by default. It allows users to organize prompts with variables and tags, import skills from a built-in store or local directories, and "one-click install" these skills into the configuration directories of various AI platforms (such as Cursor, Claude Code, and Windsurf) using either symbolic links or direct copies. It also includes a self-hosted web version for immutable backups and remote access via Docker.

Who it’s for

It is primarily for developers and AI power users who use multiple AI coding assistants and need a consistent way to manage their custom instructions, project-specific rules, and reusable AI skills across different environments.

Highlights

  • Multi-Platform Distribution: One-click installation of skills to 15+ AI tools including Cursor, Claude Code, and Cline.
  • Local-First Privacy: Data is stored on the user's machine with optional AES-256-GCM encryption for private folders and a master password.
  • Version Control: Automatic history tracking for prompts and skills, allowing for diff comparisons and one-click rollbacks.
  • AI Testing: Built-in support for parallel testing of the same prompt across multiple LLM providers (OpenAI, Anthropic, Gemini, etc.).
  • Asset Organization: Dedicated workspaces for MCP, Plugins, and Rules (.cursor/rules, CLAUDE.md) with support for project-level isolation.
  • Flexible Sync: Support for WebDAV, S3, and self-hosted web backups to keep assets synchronized across devices.
