Can I use my Claude subscription in other apps?

Yes, as long as the app runs the official Claude Code and you log in to Claude Code yourself. Anthropic's terms allow that, including when another app or platform hosts Claude Code for you. What they do not allow is an app offering its own "Sign in with Claude" or asking for your Claude session token. Usage through the permitted route counts toward the same limits as Claude chat and Claude Code.

This page lists the answer for the apps people ask about most, each with the source. Checked on 3 October 2026; the rules changed four times this year, so check the date.

What Anthropic's terms say

The rule is on Anthropic's Claude Code legal and compliance page. Subscription login "is intended exclusively for purchasers of Claude Free, Pro, Max, Team, and Enterprise subscription plans and is designed to support ordinary use of Claude Code and other native Anthropic applications."

For app makers: "Anthropic does not permit third-party developers to offer Claude.ai login into their own applications, or to route requests through Free, Pro, or Max plan credentials on behalf of their users. Moreover, developers may not collect, store, or intermediate Claude.ai credentials or session tokens."

And the exception that makes other apps possible: the rule does not "prevent an end user from signing in to the unmodified Claude Code binary with their own Claude subscription, including where a platform hosts Claude Code."

Put plainly: the app may run Claude Code. You log in to Claude Code. The app never handles your Claude login.

App by app: does it work on your Claude plan?

App	Works on your Claude plan?	How	Source
Claude Code (terminal, desktop, web)	Yes	Anthropic's own product	Anthropic help
VS Code, JetBrains IDEs	Yes	Claude Code extension, same login	Anthropic help
Cursor	Only through Claude Code	Claude Code extension or claude in the terminal. Cursor's own models bill your Cursor plan	Anthropic help ("Cursor and other VS Code forks")
Antigravity	Only through Claude Code	Same as Cursor: it is a VS Code fork. Claude models in Antigravity's own picker come with your Google plan, not your Claude plan	Anthropic help
Zed	Yes	Claude Agent (via ACP) or Claude Code in a terminal thread. Zed's built-in agent has no Claude plan option	Zed docs
Cline	Yes	Claude Code provider; needs Claude Code installed and logged in	Cline docs
OpenClaw	Yes, through Claude Code	"Claude CLI" route reuses your Claude Code login. Avoid its community "Claude Max API proxy"	OpenClaw docs
Hermes Agent	Yes, experimental	Official plugin drives the unmodified Claude Code CLI; needs Hermes 0.21.4 or newer	Hermes plugin page
Conductor, T3 Code, Happy, Munder Difflin	Yes	They drive the Claude Code logged in on your computer	Each listing quotes the maker
OpenCode	No	Removed at Anthropic's request; OpenCode says Anthropic "explicitly prohibits" the plugins that add it back	OpenCode docs
GitHub Copilot	No	Copilot's Claude agent runs on your Copilot subscription. Running Claude Code through a proxy to Copilot is unofficial	GitHub docs
Pi	Not on your plan limits	Pi's own Claude login shows Anthropic's notice that third-party usage "draws from extra usage and is billed per token". Community extensions that change this are unofficial	Pi issue #3372

The full list of apps that run on your plan, ranked by how often people open them, is on apps that use your Claude subscription.

What changed in 2026

• 20 February. Anthropic updated its legal page to say consumer-plan login may not be used in other products (The Register). OpenCode removed Claude Pro and Max sign-in.
• 4 April. Claude plans stopped covering third-party harnesses such as OpenClaw that used a Claude login directly; that usage moved to extra usage, billed separately (VentureBeat).
• 13 May. Anthropic announced that from 15 June, Agent SDK, claude -p and third-party app usage would move to a monthly credit billed at API rates (Zed's summary).
• 15 June. Anthropic paused that change. Its help page now says: "For now, nothing has changed: Claude Agent SDK, claude -p, and third-party app usage still draw from your subscription's usage limits." It says it will share any new plan before it takes effect.
• By late September. OpenClaw and Hermes Agent both document routes that run the official Claude Code instead of a direct Claude login.

Some pricing articles dated September 2026 still describe the 15 June credit as live. Anthropic's own page says it is not.

Does it cost extra?

Not for the model, while you are inside your plan's limits. Anthropic says Pro and Max limits are shared across Claude and Claude Code, and usage through Claude Code in another app counts toward them. Past your limit, work stops until the limit resets, unless you turn on usage credits, which are billed at API rates. The app may charge separately for its own features. For the maths of plan versus API, see the cost comparison.

How to tell if an app is on the permitted route

1. It sends you to Claude Code's login, or asks you to install Claude Code first. Good sign.
2. It opens its own "Sign in with Claude" window or asks you to paste a token. That is the pattern Anthropic's page prohibits.
3. It asks for an Anthropic API key. Allowed, but that is pay-per-token API billing, not your plan.
4. Check your own machine. If ANTHROPIC_API_KEY is set, Claude Code uses it instead of your subscription, Anthropic warns. Remove it and run /login.
