# Introduction
Vibe coding is about building quickly, staying focused, and keeping momentum without constantly thinking about usage limits or costs.
If you are using Claude Code through the API, the billing can grow very quickly. Frequent iterations, debugging, and experimentation make API-based workflows expensive for long coding sessions. This is one of the main reasons Claude Code Pro and Max subscriptions have become popular among vibe coders and engineers, as they provide direct access to the models without per-request pricing.
