I Cancelled Claude Code. Here's What I Use Now
Claude Code is the best coding agent I've used, and I still cancelled it. Here's why: the price and the limits, and the fine print (and the Navier–Stokes story). Then what I switched to, whether an open model will hack your PC, a live attempt to break it, and a head-to-head test on four real jobs, including where it lost.
