PromptHub

What is PromptHub?

PromptHub is a workspace where teams write, version, test and deploy the prompts behind their LLM features. Prompts are stored with Git-style branches and commits, so a team can review a change and ship it by calling an API endpoint that runs or returns the latest commit from any branch, which means no code redeploy for a prompt tweak. A playground compares outputs from OpenAI, Anthropic, Azure, Google, Meta, Bedrock and Mistral side by side, and chat, batch and dataset tests run across many cases. Evaluations use string rules or an LLM as judge, and pipelines run those checks on commits or merge requests so a version that fails does not ship. AI enhancers rewrite and improve prompts, and a community section lets people share public prompts. The Free plan has unlimited public prompts and 2,000 requests a month; Pro is $12/month, Team is $20 per user per month, and Enterprise is custom. You pay your model providers separately.

Why use PromptHub

• Prompt changes ship through an API call, so product teams can update wording without waiting on a release.
• Automated evaluations and pipelines catch regressions, secret leaks and profanity before a prompt reaches production.
• Non-technical teammates can use the playground and evals without writing code.
• Unlimited team members on the Free plan let a whole team try it before paying.
• Encryption protects your prompts, variables and outputs both when stored and while moving over the network.
