PromptHub

PromptHub is a prompt management platform for teams. It gives AI builders one home for prompt engineering. You can discover, manage, version, test, and deploy prompts from one place. The platform works for solo builders and whole teams. Public prompts can be shared with the community. Private prompts stay inside your team. PromptHub supports major models, including OpenAI, Anthropic, Google, Meta, and Mistral. It is built by Tethered Software Inc. You can get started for free, and paid team tiers unlock more.

Key Features

Prompt versioning and branches

Track every prompt change like code. Run the latest commit from any branch, so each environment always uses the most up-to-date prompt.

Side-by-side model testing

Compare model outputs on one screen before you ship. PromptHub tests prompts across OpenAI, Anthropic, Google, Meta, Bedrock, and Mistral.

Guardrails on every commit

Automated evaluator pipelines run on every commit or merge. They catch secret leaks, profanity, and regressions before they reach production.

Public prompt library

Host and share unlimited public prompts with the community. Build a portfolio, grow your reputation, and learn from other AI builders.

API deployment

Deploy prompts with a POST request to the PromptHub API. Inject variables and metadata straight from your app data.

Shareable forms

Turn any prompt into a shareable form with a few clicks. Control access, embed it anywhere, and give teammates prompt power.

Zapier integration

Push prompts into your workflows through Zapier. Pass variables, log requests, and keep every prompt in one place.

Conclusion

PromptHub turns prompt engineering into a team sport. Versioning, testing, guardrails, and one-click deployment keep prompts reliable from first draft to production. The free tier is enough to start building, and model coverage is broad. For teams shipping AI features, it ends the chaos of scattered prompts and saves real engineering time. Setup is simple enough for small teams too.
