What PromptOps Manager is

PromptOps Manager is a free, self-hosted, open-source registry for versioning, testing, and promoting large-language-model prompts. Every change receives a numbered version, preserving earlier versions, and selected versions can move independently through development, staging, or production. An asynchronous test runner supports contains, not_contains, regex, and llm_judge assertions. The llm_judge check makes a second LLM call to grade a response and explain its reasoning. Documented providers are OpenAI and Anthropic, with a fake provider for hardcoded responses. Applications and scripts can retrieve prompts through a public resolve endpoint, and the project describes an n8n workflow that fetches a production prompt. Resolve is intentionally unauthenticated, while per-consumer read tokens are planned. The MIT-licensed project uses Docker Compose for its quick start, requiring Docker 24.0 and Docker Compose v2. Its described architecture includes Laravel 11, React 18, PostgreSQL, and Redis. Team and workspace roles, a CLI, and GitHub Actions integration are roadmap items. The self-hosted plan costs nothing.

Good

  • Preserves every prompt change as a numbered version
  • Promotes versions independently across environments
  • Includes asynchronous prompt assertions and LLM judging
  • Provides API access for apps and scripts
  • MIT licensed and free to self-host

Watch out

  • Resolve endpoint requires no authentication by design
  • Team roles, CLI, and GitHub Actions are not available yet
  • Deployment requires Docker Compose and Docker prerequisites

Who it suits

PromptOps Manager suits developers who want to run their own prompt registry and control prompt promotion across environments. It is useful for teams integrating OpenAI or Anthropic prompts into apps and automations.

Verdict

PromptOps Manager offers a focused, self-hosted workflow for prompt versioning, testing, and environment promotion at no software cost. Its unauthenticated resolve endpoint and roadmap-only team features require careful consideration before production use.
