PromptHub

PromptHub is an AI prompt management and collaboration platform designed to help teams build, test, version, and deploy prompts. It takes the form of a web-based utility that centralizes prompt engineering workflows through a community-driven ecosystem and developer APIs. The platform aims to solve the disjointed process of managing prompts by replacing spreadsheets with structured version control, side-by-side testing, and automated evaluation tools.

• Git-based version control for organizing and tracking prompt changes across branches
• Side-by-side output comparison for testing and tweaking chat prompts across different models
• Automated evaluations and CI/CD pipelines of evaluators to catch secret leaks, profanity, and regressions
• API deployment for running and retrieving the latest prompt commits from any branch
• AI-assisted prompt generation and enhancement tools
• No-code prompt chaining through a point-and-click interface
• Shareable prompt forms that can be embedded and distributed anywhere
• Community-driven ecosystem for discovering, sharing, and hosting public prompts

Pros

• Provides robust version control and branching for prompts, bringing software engineering practices to prompt management
• Enables side-by-side model output comparisons to quickly evaluate changes against multiple LLM providers
• Offers automated evaluation pipelines to run checks against regressions and secret leaks on every commit or merge
• Supports flexible team collaboration features, including private prompts, team permissions, and shared workspaces

Cons

• The Free tier limits users to 2,000 requests per month, 10 prompt enhancements per month, and zero private prompts
• The Pro tier is restricted to single users, preventing multi-user collaboration at that price point
• SOC 2 compliance is currently listed as in progress rather than fully achieved
• Request limits apply across all paid tiers unless an Enterprise custom plan is negotiated

PromptHub fits developer teams, prompt engineers, and cross-functional product groups looking to centralize their prompt libraries, run systematic evaluations, and collaborate on private or public prompts. It is well-suited for organizations that want to integrate prompt management directly into their development pipelines via API or Zapier. It is a poor fit for solo users or organizations that require heavy usage without upgrading past the limited free tier, or those needing strict compliance certifications that are still in progress.

PromptHub operates on a freemium model with monthly and yearly billing options, offering a 25% discount on yearly plans. The Free tier includes unlimited team members, unlimited public prompts, no private prompts, limited API access, 2,000 requests per month, and 10 prompt enhancements per month. The Pro tier costs $12/month when billed monthly (or $9/month with yearly billing) for solo users, providing single-user access, unlimited private prompts, full API access, 10,000 requests per month, and 200 prompt enhancements per month. The Team tier costs $20/user/month when billed monthly (or $15/user/month with yearly billing), offering unlimited team members, unlimited private and public prompts, 50,000 requests per month, 500 prompt enhancements per month, evaluations, pipelines, team and user permissions, and private Slack channel support. The Enterprise tier uses custom pricing for team

Unlike traditional spreadsheets or general documentation tools where teams often paste and track prompts manually, PromptHub treats prompts like code by implementing Git-based version control and branching. It differentiates itself from generic LLM chat interfaces by combining a prompt playground, automated evaluation pipelines, and programmatic deployment endpoints into a single collaborative workspace. Rather than just storing text, it integrates testing, version tracking, and deployment workflows directly into engineering cycles.

PromptHub is worth trying for teams and developers seeking to replace scattered spreadsheets with an organized prompt engineering lifecycle. The free tier lets users test out features and explore public prompts, though it lacks private workspaces and caps monthly requests. Teams needing robust collaboration, automated evaluation pipelines, and private prompt repositories will need to evaluate the Pro or Team paid tiers. Those requiring strict enterprise controls or custom model support can contact the provider for an Enterprise agreement.
