Description
I think in-process key management is the right abstraction for multi-key LLM setups. Not LiteLLM, not a Redis queue, not a custom load balancer.The failure modes are well-understood: a key gets rate-limited, you wait, you try the next one. Billing errors need a longer cooldown than rate limits. This is not a distributed systems problem — it's a state machine that fits in a library. The problem is everyone keeps solving it with infrastructure instead. Spin up LiteLLM, now you have a Python service to maintain. Reach for Redis, now you have a database for a problem that doesn't need one. key-carousel manages a pool of API key profiles with exponential-backoff cooldowns: 1min → 5min → 25min → 1hr for rate limits, 5hr → 24hr for billing. Falls back to OpenAI or Gemini when Anthropic keys are exhausted. Optional file persistence. Zero dependencies.

Could you build this?
Yes key-carousel is a simple in-process API key rotation and cooldown management library handling HTTP status code errors and rate limits.
Discussion

Competitors mentioned: LiteLLM, OpenClaw
Concerns raised: Operational overhead for infrastructure approach not justified vs simple retry logic, Key exhaustion behavior when all profiles in backoff - blocking vs error handling unclear
