Claude Pro and Max look cheap, but heavy coding can hit limits fast

Claude users are debating whether the $20 Pro plan is still a good deal when usage limits can arrive quickly. Tools such as Codex Bar show how much a session would cost if the same work were paid for directly with API tokens, and that comparison can make a subscription look much cheaper than pay-as-you-go API use. For solo builders using Claude Code, Cursor, or similar coding tools, Pro or Max can still offer strong value when the work would otherwise create a large API bill.

The concern is that Sonnet 5 appears to use many tokens while giving fast and careful answers. For complex architecture work in a large codebase, it may examine many possible paths instead of jumping into the first likely answer, which can be useful but expensive. One reported test question ran for about 19 minutes and used 28% of a 5-hour Pro usage window, even though the answer was considered good.

Another pattern is that running two coding sessions at once can burn through a Pro window in about 1 to 1.5 hours and reach weekly limits within a few days. People spending around $1,000 a month on Anthropic API credits are now comparing that habit against the Max plan to see whether the subscription is the cheaper route.
