Promptmetheus
Prompt engineering IDE for composing and testing LLM prompts
Promptmetheus is profiled here as a Prompt Management tool for engineering teams. Read about features, pricing, and how it compares to related options in the tools directory.
Description
Promptmetheus is a prompt engineering IDE that helps developers compose, test, and optimize prompts for large language models. The tool splits each prompt into reusable blocks so teams can adjust individual pieces and watch how every change moves the output. It connects to dozens of models across OpenAI, Anthropic, Google, Mistral, and local runtimes, which gives one workspace for comparing behavior across providers before a prompt ships.
Key Capabilities:
Block-based prompt composition that separates context, instructions, and examples into editable units
Cross-provider testing across OpenAI, Anthropic, Google, Mistral, and self-hosted models
Cost estimation that calculates token spend for a prompt before a production run
Prompt versioning with a traceable history of edits and their outputs
Datasets and scoring that grade prompt variants against fixed test inputs
Shareable prompt collections that let a team reuse and review work together See Promptmetheus pricing details
