PromptHub is a collaborative platform for managing AI prompts as real engineering assets: git-based versioning, side-by-side output comparison across models from OpenAI, Anthropic, Azure, Google, Meta, Bedrock and Mistral, no-code prompt chaining, and deployment as an API, a shareable form, or through Zapier and pipeline guardrails. A public community layer lets teams browse and share thousands of prompts alongside the private team workspace.
Treating prompts with the same version control and testing discipline as code – rather than as text pasted into a chat window and forgotten – is the real shift this enables for a team actually building on top of LLMs: a prompt that silently regresses after a model update is a genuine production problem, and git-based versioning with side-by-side comparison catches that before it ships. Named enterprise customers (WSJ, Shopify, Adobe, Cisco, Accenture) back this as production-grade infrastructure, not a hobbyist tool.
This is built for teams with real prompt-engineering workflows, not casual one-off prompt writing – the versioning and deployment tooling is overhead a single user experimenting occasionally doesn’t need. Specific pricing wasn’t shown on the homepage checked beyond a free starting tier.
