PromptForge

What PromptForge is

PromptForge is a prompt development and deployment platform for teams working with multiple model providers. Its workbench supports chat, image and video, speech, transcription, and embeddings, with a curated model catalog, streaming previews, and version history. Users can batch-test prompts against datasets, run evaluators and A/B tests, and schedule regression checks. Configurable release gates can require a pass-rate threshold before release, using the app or APIs and CLI tools such as GitHub Actions. Versioned deployments can use environment pins, invoke URLs, optional schedule guards, and API keys. A visual flow builder combines prompt steps, HTTP calls, and logic into versioned deployments. PromptForge also reports cost, latency, and quality signals from test and production logs. Its shared media library holds uploaded and generated images, video, and audio, with metadata, bulk actions, and links to saved or draft prompts. Users can 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 of storage; paid plans add capacity and collaboration controls.

Who it suits

PromptForge suits people building, evaluating, and deploying prompts across multiple models, especially when dataset tests and pass-rate release gates are part of their workflow. Teams needing shared workspaces, access controls, or enterprise identity options can consider its higher plans.

Limits

The free plan covers one user, three projects, 200 test runs per month, and 1 GB of storage. Pro allows 5,000 test runs per month and one deployment endpoint; Team allows 25,000 test runs per month and five endpoints.

1. Open the PromptForge web app.
2. Sign up for the free plan without a credit card.
3. Connect a model provider using your own key.
4. Create a project and use a workbench mode to build a prompt.
5. Run dataset tests, then configure a release gate or deployment.

Verdict

Choose PromptForge if you need a place to test, gate, version, and deploy prompts across model providers. Its free plan includes core testing and BYOK, while teams needing more runs, collaboration controls, or enterprise features will need a higher plan.
