One Fox key

A durable credential for your local tools.

Usage visible

01

Stop rotating fragile credentials.

Your application key stays put while Fox maintains the account connection behind it.

02

See where the requests go.

Clear usage totals make experiments visible without adding a monitoring stack.

03

Keep your account in its lane.

Every connection is isolated, with explicit controls around how it can be used.

02 / From zero to request

Four steps.
No scavenger hunt.

The entire setup happens in one guided path. No dashboard maze, mystery credentials, or hand-built refresh logic.

One account.
One boundary.

Fox is designed around explicit connections, not pooled credentials or invisible account sharing.

  • Account connections stay isolated.
  • Application keys can be revoked independently.
  • Usage totals remain visible to you.

04 / Before you connect

The obvious questions.

Do I need a Claude Max account?

Yes. Fox connects an eligible Claude Max account that you already control.

Does this replace my Claude subscription?

No. Your provider subscription remains separate and must stay active and eligible.

Can I revoke an application key?

Yes. Application credentials are separate from the underlying account connection and can be revoked independently.

Is this signup form live?

Yes. Submitting your address sends a verification link by email. Fox retains the signup record needed to issue and secure that link.

Ready when you are

One connection away.
