Being in the same boat as you I switched to OpenCode with z.ai GLM 4.7 Pro plan and it's quite ok. Not as smart as Opus but smart enough for my needs, and the pricing is unbeatable
Ditto. It is very very slow but I never hit quota limits but people on Discord are complaining like mad it is slow even on the Pro plans. I tend to use glm-*air a lot for planning before using 4.7
I've also see OpenCode around, but have yet to try it. I wonder how it compares to Roo Code
