ElevenLabs Rate Limits

Overview

Handle ElevenLabs rate limits with plan-aware concurrency queuing, exponential backoff, and quota monitoring. ElevenLabs uses two rate limit mechanisms: concurrent request limits (per plan) and system-level throttling. The key insight is that a 429 means two different things depending on its detail.status — and each demands the opposite response.

Prerequisites

• ElevenLabs SDK installed (@elevenlabs/elevenlabs-js)
• Understanding of your subscription plan's limits
• p-queue package (recommended): npm install p-queue
