Can I use my Claude subscription with multiple coding agents?
Short answer
Yes for Claude Code: every Claude Code session you start, in as many terminals or worktrees as you like, runs on the same Claude Pro, Max or Ultra plan and shares its usage limits. Other vendors' agents need their own plan, so Codex uses a ChatGPT plan or OpenAI API key, and Cursor bills Claude models at API list price outside its plans.
How the limits work with several sessions
Claude Code is included in every paid Claude plan and shares the same usage limits as the rest of the plan. Your chats on the web, the desktop and mobile apps and Claude Code all draw from one pool that resets every 5 hours, with weekly limits on top. Three Claude Code sessions running at once all draw on that one pool, and Claude Code's docs note that parallel sessions multiply token usage.
If you hit the limit often, Max gives 5x Pro usage for $100 a month, and Ultra removes the 5-hour limit and gives 10x Pro usage each week for $200.
Using Claude models in other tools
- In Cursor, Claude models are available on Premium and above at API list price, billed separately from Cursor's plan. Your Claude subscription doesn't cover them.
- Setting
ANTHROPIC_API_KEYand approving it in Claude Code switches billing to per-token API rates instead of your plan.
In Zoltbot
Zoltbot runs Claude Code through its own CLI and reuses your existing login, so every Claude Code chat and task in every project uses your one Claude plan. It never asks for your password or copies your credentials. Codex, Cursor and Antigravity run on their own logins next to it.
