PromptForge

What PromptForge is

PromptForge is a platform for building, testing, and deploying prompts and multimodal workflows. Its workbench includes chat, image and video, speech, transcription, and embeddings modes, with a model catalog, streaming previews, and version history. Users can run prompts against datasets in batches, apply evaluators and A/B tests, and schedule regression checks. Release gates can enforce a configured pass-rate threshold in the app or through APIs and CLI tools, including GitHub Actions. Deployments support environment pins, invoke URLs, optional schedule guards, and API keys. A visual builder combines prompt steps, HTTP calls, and logic into versioned flow deployments. The platform reports cost, latency, and quality signals from test and production logs, and its shared media library stores uploaded and generated images, video, and audio with metadata and links to prompts. Users connect providers with their own keys, including OpenAI, Anthropic, and Google. The Free plan includes one user, three projects, 200 test runs per month, and 1 GB storage.
