Claude Code rate limits: how to never hit them again

You're deep in a refactor. Claude Code is flying. Then:

Claude API rate limit exceeded. Please wait before retrying.
Enter fullscreen mode Exit fullscreen mode

Session dead. Context lost. Flow broken.

Here's everything I know about avoiding this.

Why rate limits happen

Claude Code burns tokens fast. Every file read, every tool call, every response — it all counts. A single complex task can consume thousands of tokens in minutes.

Anthropics rate limits are per-API-key, not per-session. So if you're running multiple Claude Code windows, they share the same bucket.

Fix 1: ANTHROPIC_BASE_URL (the real fix)

This is the one that actually works:

export ANTHROPIC_BASE_URL=https://simplylouie.com/api
export ANTHROPIC_API_KEY=your-key
claude
Enter fullscreen mode Exit fullscreen mode

This routes Claude Code through a proxy with higher throughput. The proxy handles rate limit queuing transparently — you never see the error.

I've been running this setup for months. Mid-session interruptions dropped to zero.

SimplyLouie proxy: $2/month, no limits on requests. Details at simplylouie.com

Fix 2: Compact aggressively

Before your context fills up:

/compact
Enter fullscreen mode Exit fullscreen mode

This summarizes the conversation history into a dense context block. You lose verbatim history but keep the important state. Claude Code can continue working without a full reset.

Do this proactively, not reactively. When the context bar hits 50%, compact.

Fix 3: Scope your tasks smaller

Rate limits are triggered by large unbounded tasks:

# BAD - this will burn your entire rate limit budget
claude "refactor the entire codebase to use TypeScript"

# GOOD - bounded scope, predictable token usage
claude "convert src/utils/helpers.js to TypeScript only"
Enter fullscreen mode Exit fullscreen mode

Smaller tasks = smaller token bursts = rate limits never triggered.

Fix 4: .claudeignore the noise

Every file Claude Code reads counts against your quota. Exclude what it doesn't need:

# .claudeignore
node_modules/
dist/
.git/
*.log
coverage/
.next/
Enter fullscreen mode Exit fullscreen mode

This alone can cut token usage by 40-60% on large projects.

Fix 5: One Claude Code window

Multiple terminal windows = multiple API streams sharing one rate limit.

Use parallel agents within a single session instead:

claude "spawn subagents to handle: 
  1. Write tests for auth.js
  2. Fix linting errors in utils/
  3. Update README
Run them in parallel, report results"
Enter fullscreen mode Exit fullscreen mode

Single window, parallel work, shared rate limit budget used efficiently.

Fix 6: Use hooks to skip unnecessary reads

Claude Code will re-read files it's already seen if you don't stop it. Add a hook:

// .claude/settings.json
{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Read",
        "hooks": [
          {
            "type": "command",
            "command": "echo 'Reading: $CLAUDE_TOOL_INPUT_FILE_PATH'"
          }
        ]
      }
    ]
  }
}
Enter fullscreen mode Exit fullscreen mode

This makes file reads visible so you can catch redundant reads and instruct Claude to skip them.

The real answer: remove the ceiling

All the above tips help. But they're workarounds for an artificial constraint.

The real fix is routing through a proxy that doesn't impose the same rate limits:

export ANTHROPIC_BASE_URL=https://simplylouie.com/api
Enter fullscreen mode Exit fullscreen mode

One env var. No rate limit errors. $2/month.
