Description
Prompt Workbench is a local, open-source developer application for creating, versioning, testing, comparing and publishing LLM prompts and linear prompt chains. Develop and compare prompts locally, then ship the exact versions you tested as ordinary, portable files that any language can load — with no cloud account and no vendor lock-in.
