# Best AI coding plan for vibe coding

Verified 2026-10-14. Every figure is copied from the official vendor page; unknown means the vendor does not publish it.

Vibe coding means describing what you want and letting an agent write most of the code. That burns through agent allowance, so the limit model matters more than the entry price.

## Where each agent runs

- Cursor (editor): Cursor (VS Code fork)
- Claude Code (terminal): Terminal / any editor
- OpenAI Codex (terminal+cloud): CLI, IDE extension, web, Codex app
- GitHub Copilot (extension): VS Code, Visual Studio, JetBrains, Neovim, Xcode, Zed, Eclipse, CLI
- Windsurf (now Devin Desktop) (editor): Devin Desktop (formerly Windsurf, VS Code fork) + JetBrains plugin


## How agent usage is metered

- Cursor: Shared AI usage pool across Cursor and Grok; allowance refreshes weekly; third-party models billed separately at API list price; top-offs available.
- Claude Code: Rolling 5-hour session window plus weekly limits on paid plans; Claude Code shares the pool with Claude chat; no fixed message count published; optional usage credits at API rates.
- OpenAI Codex: Included in ChatGPT plans. Plus: estimated local messages per 5-hour window (e.g. GPT-6.1 Sol 15-160, GPT-6 Astra 5-45), weekly limits may apply. Pro: no 5-hour limit currently. Credits extend usage.
- GitHub Copilot: Monthly GitHub AI Credits (1 credit = $0.01) = base + variable flex allotment; resets monthly; completions unlimited on paid plans; overage at $0.01/credit with a budget.
- Windsurf (now Devin Desktop): Quota allowance refreshing daily and weekly; extra usage at API pricing. windsurf.com/pricing now redirects to devin.ai/pricing (checked 2026-10-14 18:15 CT).
