Feature Request: Multi-Account Support with Automatic Failover #8864

Feature Request

Description

I would like to request a feature that allows users to configure multiple accounts for the same provider. When one account reaches its session or weekly rate limit, the system should automatically switch to the next available account.

Use Case

When using AI providers like Claude / Claude Code, accounts often hit rate limits (session limits, weekly limits, etc.). Currently, this interrupts the workflow and requires manual intervention to switch accounts.

With multi-account support and automatic failover:

• Users could configure multiple accounts (e.g., personal + work accounts)
• When the primary account hits a limit, the system automatically uses the next account
• This ensures uninterrupted workflow and better utilization of available quotas

Proposed Behavior

1. Allow configuration of multiple accounts per provider (e.g., multiple Anthropic API keys or Claude accounts)
2. Detect when an account reaches its rate limit (session/weekly/monthly)
3. Automatically failover to the next configured account
4. Optionally notify the user when a switch occurs
5. Rotate back to the primary account when limits reset

Example Configuration (conceptual)

[providers.anthropic]
accounts = [
  { name = "primary", api_key = "..." },
  { name = "secondary", api_key = "..." },
]
failover = "auto"

Benefits

• Uninterrupted workflow during rate limits
• Better utilization of multiple subscriptions/quotas
• Improved developer experience

Thank you for considering this feature!
