What PromptHub is

PromptHub is a platform for discovering, organizing, versioning, testing, and deploying prompts. Users can publish public prompts for the community, while keeping prompts private with teammates requires a paid plan. Git-based versioning tracks prompt changes, and an API supports prompt management and deployment. Evaluations run against test cases and let users compare outputs side by side. Pipelines can run checks on commits or merges for secret leaks, profanity, and regressions. Listed model providers for testing include OpenAI, Anthropic, Azure, Google, Meta, Bedrock, and Mistral. Prompts can be deployed through the API, shareable forms, or Zapier. The Free plan permits unlimited public prompts and team members, but excludes private prompts and provides 2,000 requests per month with limited API access. Pro is $12/month for one user; Team is $20/user/month. Customers need their own LLM API keys and pay model providers' token costs separately.

Who it suits

PromptHub may suit individuals or teams who need to organize and evaluate prompts across multiple model providers. Teams wanting private prompts, shared permissions, or broader API access can consider its paid plans.
