What PromptVersions is
PromptVersions is a web workspace for creating, organizing, evaluating, and deploying prompts for large language models. It supports OpenAI, Anthropic, Google, DeepSeek, xAI, Mistral, and OpenRouter. Each save creates an immutable version with a commit message; users can compare versions or restore an earlier one. Ordered prompt chains let later steps use earlier outputs. Teams can define metrics and test cases, evaluate versions in batches, or run evaluations whenever a prompt is saved. Versions can be assigned to development, staging, and production environments, tested through A/B experiments, and called using an inference API. Workspaces offer owner, editor, and viewer roles, while signed webhooks cover deployments, stopped A/B tests, and evaluation runs. Users supply their own provider API keys, and provider usage is billed directly by those providers. The Free plan costs nothing, with no payment method or charges.

Prompt engineers can manage prompt versions and evaluations in one workspace. Product managers, writers, and analysts who edit prompts may also use it, with team roles for shared access.
