In their own words
PromptForge
PromptForge is a web and API platform for building, testing and deploying multimodal prompts. Its workbench includes chat, image and video, speech, transcription and embeddings modes, with a model catalog, streaming previews and version history. Teams can batch-test prompts on datasets using evaluators, A/B tests and scheduled regression runs. Release gates enforce a configured pass-rate threshold through the app, APIs or CLI tools, including GitHub Actions. Versioned deployments offer environment pins, invoke URLs, optional schedule guards and API keys. A visual builder links prompt steps, HTTP calls and logic into versioned flows. Production and test logs provide cost, latency and quality signals. The media library stores uploaded and generated images, video and audio with metadata, bulk actions and links to prompts. BYOK connections support providers including OpenAI, Anthropic and Google. The free plan is free for one user, three projects, 200 test runs monthly and 1 GB storage.
