About PromptForge

Build type-safe AI prompts with TypeScript

PromptForge is an open-source TypeScript toolkit for building production-ready AI prompts. Define prompts with type-safe schemas, validate inputs before expensive LLM calls, compose reusable prompt blocks, and compile prompts for multiple AI providers. Built for developers who want maintainable, scalable, and reliable prompt engineering workflows. MIT licensed and developer-first.

Next step: <p>PromptForge can be taken further from an open-source prompt-engineering toolkit into a complete AI developer platform. A buyer could build a hosted SaaS around the existing foundation with a visual prompt builder, prompt library and version control, team collaboration, analytics, evaluation/testing, model comparison, and API access. Additional opportunities include integrations with OpenAI, Anthropic, Gemini, and Ollama, enterprise features, usage-based or subscription pricing, and a marketplace for reusable prompts and workflows. The existing TypeScript architecture and CLI provide a foundation for expanding into a broader developer-focused AI tooling ecosystem.</p>
