What PromptForge is
PromptForge manages prompt templates and makes them available through a REST API, for AI developers who want to change prompt text without redeploying application code. Templates can include reusable placeholders written with {{variable}} syntax. Each edit creates an immutable version, and applications can request a stable, latest, or specifically chosen version. Users can compare line-by-line differences and roll back to an earlier version. The API uses Bearer token authentication and GET or POST requests to retrieve prompts. Listed integrations include OpenAI, Anthropic Claude, Google Gemini, Grok, Groq, Mistral, Vercel AI SDK, Ollama, Cohere, Together AI, Azure OpenAI, and AWS Bedrock. PromptForge stores, organizes, versions, and shares text prompts; it does not perform AI execution, generation, analysis, or training. The free Hobby plan allows one production prompt and 1,000 API requests per month. Starter costs $9/month, Pro $29/month, and Business $49/month. The terms state that there is no export feature or formal SLA or uptime credits.
Good
- Immutable versions with diff and rollback tools
- Reusable template variables
- REST API supports GET and POST requests
- Integrations span multiple listed providers and tools
Watch out
- No export feature
- No formal SLA or uptime credits
- Does not perform AI generation or analysis
Who it suits
PromptForge suits AI developers who want to manage prompt versions and serve them to applications through an API. It is not for users seeking a service that runs prompt generation or analysis.
Verdict
PromptForge focuses on versioned prompt storage and API delivery rather than AI execution. Its free tier has one production prompt and 1,000 monthly requests; paid plans provide larger listed allowances.
