Some variation of this is the way.

You should not get dependent on one black box. Companies will exploit that dependency.

My version of this is having CC Pro, Cursor Pro, and OpenCode (with $10 to Codex/GLM 5.1) --> total $50. My work doesn't stop if one of these is having overloaded servers, etc. And it's definitely useful to have them cross-checking each other's plans and work.

This more or less mimics a flow that I had fairly good results from -- but I'm unwilling to pay for both right now unless I had a client or employer willing to foot the bill.

Claude Code as "author" and a $20 Codex as reviewer/planner/tester has worked for me to squeeze better value out of the CC plan. But with the new $100 codex plan, and with the way Anthropic seemed to nerf their own $100 plan, I'm not doing this anymore.
