Claude 4 is here but is is good at Convex?
Claude 4 just dropped from Anthropic—and it’s already sparking debates among developers building full-stack apps with modern backends like Convex. This video tests Claude 4’s real-world dev performance in two live builds: spinning up an Instagram clone in Chef and upgrading a local Tic-Tac-Toe game with Convex as the backend.
If you’re a developer comparing Claude 4 vs Claude 3.5 for agentic codegen, backend integration, or app workflows with Convex + Cursor, this is the walkthrough to watch. From schema generation to real-time photo uploads and environment variable debugging, you’ll see where Claude 4 shines—and where it still struggles compared to its predecessors.
This video doesn’t just look at benchmarks—it shows you how Claude 4 handles practical backend and fullstack coding tasks. You’ll see what works, what breaks, and where it still lags behind Claude 3.5, especially when Convex is in the mix.
Convex is the backend platform with everything you need to build your full-stack AI project. Cloud functions, a database, file storage, scheduling, workflow, vector search, and realtime updates fit together seamlessly.
