Great question, happy to answer!

There are a couple of differences: Garph is easier to use than Pothos, Garph fully supports circular references (no workarounds!) and Garph solves type-safety for clients without the need for code-gen. We also offer a compatible client for React/Next.js based on GQty (formerly GQless) for the best experience

Pothos is great for backend-only applications and if you need advanced features such as Relay right now. Garph is great if you want the best possible developer experience and type-safety on both ends of your stack
