PromptForge review
A low-cost prompt API with version control, routing, templates, and provider support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PromptForge is a web-based prompt management service from Mavity for developers and production teams that need to keep text-based AI prompts outside application code. It stores immutable sequential versions, supports reusable templates with dynamic variables, and serves rendered prompts through REST API endpoints. Teams can route stable, latest, or pinned versions and manage prompts across supported model providers, including OpenAI, Anthropic Claude, Google Gemini, Mistral, xAI Grok, Groq, DeepSeek, Ollama, Meta Llama, Cohere, Together AI, Azure OpenAI, and AWS Bedrock.
Version control is the product’s central strength. Line-by-line diff review, rollback, staged promotion from latest to stable, and environment-scoped API key management give teams a defined path from prompt changes to production delivery. The public prompt gallery and sharing features also support collaboration, while the web and API access fit teams that want prompt operations separated from application deployments. PromptForge is focused on managing and serving prompts rather than executing, generating, analyzing, or training AI models within the app.
Pricing is structured for teams that want to start small. The free Hobby Plan includes 1 production prompt, 1,000 API requests per month, stable/latest channel routing, and no credit card requirement. Starter costs $9 per month and adds 10,000 requests, 5 prompts, unlimited versions, dynamic variables, version pinning, and API key management. Pro costs $29 per month with 100,000 requests and 25 prompts, while Business costs $49 per month with 500,000 requests and 100 prompts; both retain the listed Starter capabilities. PromptForge suits teams building prompt APIs with modest or growing request volumes. Teams seeking in-app AI execution should choose a different type of tool.
