PromptHub

Overview

PromptHub is a web and API platform for discovering, organizing, versioning, testing, and deploying prompts. It suits people who want to collaborate on prompts and check changes against test cases; its public-prompt sharing and Git-based history are balanced by private prompts being a paid-plan feature.

Its strongest case is a workflow that connects prompt changes to evaluations and event-triggered checks. Account for request and enhancement caps, and for model-provider token charges outside the subscription.

Key features

Shared prompts and version history

Free users can publish unlimited prompts to the community, while keeping prompts private with teammates requires a paid plan. That makes the free tier useful for public prompt work, but unsuitable for confidential projects. Git-based versioning and an API for managing and deploying prompts give teams a way to track changes rather than treating each prompt as a one-off.

Evaluations and pipelines

Evaluations compare outputs across test cases, including side-by-side comparisons. Pipelines can run evaluator workflows on commits or merges and check for secret leaks, profanity, and regressions. This makes PromptHub more compelling for teams that want checks tied to prompt changes; request and enhancement quotas still shape how much work each plan can handle.

Providers, integrations, and security

Testing spans OpenAI, Anthropic, Azure, Google, Meta, Bedrock, and Mistral. Deployment options include the API, shareable forms, and Zapier. Customers supply their own LLM API keys and pay providers separately for token use, so subscription prices do not cover model usage.

PromptHub says prompts, variables, and outputs are encrypted at rest and in transit using AES-246, TLSv1.2+, and regularly rotating keys. Enterprise lists SSO and SAML, with SOC 2 in progress. Data exports can be requested through [email protected]; Team includes a private Slack support channel.

Pricing

PromptHub is freemium. The Free plan costs nothing and allows unlimited team members and public prompts, 2,000 requests/month, and 10 prompt enhancements/month, with limited API access. It excludes private prompts, so it is best for public experiments rather than private team projects.

Pro costs $12 a month, billed $12/month, for a single user. It adds unlimited public and private prompts, 10,000 requests/month, 200 prompt enhancements/month, and full API access. The single-user limit makes it a fit for individual prompt work, not shared team ownership.

Team costs $20 a month, billed $20/user/month. It includes unlimited team members and public and private prompts, 50,000 requests/month, 500 prompt enhancements/month, team and user permissions, and private Slack channel support. This is the clearest fit for collaborative work, though the per-user price and monthly quotas matter as a team grows.

Enterprise has custom pricing, with SSO and SAML, custom limits and roles, custom model support, and dedicated support and feedback; SOC 2 is in progress. Choose it for organization-specific controls or support needs. The listed paid-from price is $9/user/mo (annual), so confirm the term and plan price before budgeting. Model-provider token costs remain separate on every plan.

Platforms

PromptHub supports web and API access. Full API access is included with Pro and higher; Free has limited API access.

Who it's for

PromptHub is a strong candidate for individuals and teams who need prompt version history, multi-provider testing, and evaluations that can run when changes are committed or merged. Free suits public prompt sharing, Pro suits a solo user needing private prompts and full API access, and Team suits shared private work with permissions. It is a weaker fit for anyone who needs private prompts on a free tier or wants model token charges included in the subscription.

Pros and cons

• Pro: Git-based versioning, evaluations, and event-driven checks connect prompt changes with review and regression checks.
• Pro: Public prompt sharing is unlimited even on Free, and provider testing covers seven named ecosystems.
• Con: Free excludes private prompts, and its 2,000 monthly requests and 10 monthly enhancements constrain ongoing use.
• Con: Pro is single-user; teams need the per-user Team plan for shared permissions and private collaboration.
• Con: API keys and provider token charges are separate, so subscription pricing is not the full operating cost.

Verdict

Choose PromptHub if you want prompt version control and collaboration joined to evaluations and checks that run on commits or merges. Its Team plan is the most natural fit for shared private workflows; look elsewhere if private prompts must be free or if you need provider token costs bundled into the subscription.
