What is Promptmetheus?
Promptmetheus is a prompt engineering IDE for developers and teams building LLM-powered applications, agents, and workflows. It lets users compose structured prompts from text and data blocks, iterate on block variants, and test prompts against 150+ models from providers such as OpenAI, Anthropic, and DeepMind. Features include automatic evaluators, test datasets, prompt variables, completion ratings, versioning with changelogs, cost estimation, and real-time sync. It is sold with a free Playground plan, a Single plan with a 7-day free trial, and a Team plan with shared workspaces; inference is billed separately through the user's own API keys.
