Promptmetheus is a prompt engineering IDE for developers building LLM-powered apps, agents, and workflows. Its Archery app breaks prompts into block sections like Context, Task, Instructions, Samples, and Primer so you can vary each piece without rewriting the whole thing. You test completions against 150+ models from 15 API providers, rate outputs, and track changes across projects. A free Forge playground handles lighter local OpenAI testing.

Where provider playgrounds stop at one-off chat tests, Promptmetheus treats prompt design like structured software work. Datasets let you rerun the same prompt against different inputs, automatic evaluators flag constraint violations on each completion, and version history logs every edit in the chain. That focus on repeatability and team libraries sets it apart from general code assistants that embed prompts inside application code without a dedicated testing loop.

It fits prompt engineers, AI developers, and product teams shipping LLM features who need shared workspaces and traceable experiments. Consultants and university groups use Team accounts for real-time collaboration on prompt libraries. Anyone who already has API keys can plug them in, since subscriptions cover the IDE only, not inference spend.
