Claude Max 20x can run out fast during serious SaaS coding
An AI-powered SaaS product used Claude for one fairly complex development workflow. In about 35 minutes, the session reached 94% usage, even though almost three hours remained before the limit reset.
The work included reviewing existing code and structure, following logic across several files, finding issues, suggesting fixes, implementing changes, and checking that the workflow worked. Claude completed a large amount of work quickly, but the usage limit dropped much faster than expected.
More context can make Claude more useful, but large codebases and long can burn through limits quickly. Smaller tasks, less unnecessary , and separate sessions for planning and may help control usage.
