PromptHub

PromptHub is an open-source AI prompt and skill management tool built as an all-in-one AI agent toolbox. It brings prompt management, skill management, and agent asset management into one place, with a local-first design intended for people who want to manage prompts and SKILL.md assets without switching between different agent tools.

Its core functions include a built-in skill store with more than 20 curated AI agent skills for tasks such as code review, documentation writing, and test generation. The tool can install SKILL.md to more than 15 platforms, including Claude Code, Cursor, Windsurf, Qoder, CodeBuddy, and Codex, using symlink, copy, or target-directory overwrite methods. PromptHub also supports parallel comparison of domestic and international large language models, version change tracking with diff comparison and one-click rollback, a {{variable}} syntax parser for reusable prompts, and dynamic forms for more complex input. In addition, it offers SQLite FTS5 full-text search, automatic scanning of local directories for existing SKILL.md files, preview and batch import, AI translation for imported skills, and export to JSON, YAML, or CSV.

The product is aimed at AI engineers and is described as local-first: all data is stored locally with AES-256 encryption, and it can be used offline without network connectivity. It is presented as a downloadable client and as a community-driven open-source project.
