Claude Code: subscription or API billing?
For heavy Claude Code use, is a subscription plan or pay-as-you-go API billing the better deal? And how do you keep usage under control either way?
It depends on how steady your use is. A subscription is a fixed monthly price with usage limits; API billing charges per token with no fixed cap. Check Anthropic's current pricing pages, because plans and limits change.
Steady daily use usually favours a subscription. Bursty or automated use (scripts, CI, many parallel runs) is often easier to reason about on the API, where every run has a visible cost.
Either way, most waste comes from long, unfocused sessions. Planning first, keeping tasks small and starting fresh sessions for new tasks cut usage more than any plan switch.
Subagents help too: a focused subagent with a short brief does not drag the whole conversation history along.
