Frequently Asked Questions

Is ProtoForge free?
Yes! ProtoForge is completely free and open-source under the MIT license. You only need to provide your own API key for an AI provider (many have free tiers).
What API providers work best?
For free tier usage, we recommend Groq (very generous limits), Together AI, or SiliconFlow. All support free API keys that work great with ProtoForge.
Can I run this locally?
Absolutely. ProtoForge runs entirely on your machine. The backend is a Python server, and there's also a native macOS desktop app available as a .dmg download.
What kind of prototypes can I build?
Three modes: Software (web apps, APIs, scripts), Hardware (circuit diagrams, 3D models, BOMs), and Hybrid (combined hardware+software like IoT devices).
Do you store my API keys?
No. Your API keys are sent directly to the provider. ProtoForge never stores or proxies your keys.
