Claude Code rate limits: why they happen and 6 ways to fix them

You're deep in a refactoring session. Claude Code is rewriting your auth module, running tests, fixing failures. Then:

Error: rate_limit_error - Too many requests
Enter fullscreen mode Exit fullscreen mode

Everything stops. Your flow is broken. Here's why this happens and how to fix it.

Why Claude Code hits rate limits

Claude Code is token-hungry by design. A single session can easily consume:

  • 10,000+ tokens reading your codebase
  • 5,000+ tokens per complex refactor
  • 2,000+ tokens per test-fix cycle

Anthropic's API has per-minute and per-day token limits. Heavy Claude Code sessions hit these fast.

Fix 1: Switch to a proxy via ANTHROPIC_BASE_URL

This is the real fix. Instead of hitting Anthropic's API directly, route through a proxy with higher or no limits:

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

The proxy handles rate limit management so Claude Code never sees a limit error. This is the approach that actually works for heavy daily users.

Fix 2: Use --model to pick a less rate-limited tier

Opus hits limits fastest. Sonnet is more generous:

claude --model claude-sonnet-4-5
Enter fullscreen mode Exit fullscreen mode

For tasks that don't require maximum intelligence (formatting, renaming, simple refactors), Sonnet often works just as well.

Fix 3: Use /compact aggressively

Context bloat drives token consumption. Run /compact before every major task boundary:

/compact
Now refactor the payment module
Enter fullscreen mode Exit fullscreen mode

This compresses the conversation history, dramatically reducing tokens per turn.

Fix 4: Use .claudeignore to shrink your context

If Claude Code is indexing node_modules, build artifacts, or test fixtures, you're burning tokens on files that don't matter:

# .claudeignore
node_modules/
dist/
build/
*.min.js
coverage/
.next/
Enter fullscreen mode Exit fullscreen mode

This can cut your token usage by 50%+ on large projects.

Fix 5: Split sessions by scope

Instead of one giant Claude Code session for "refactor the whole app", split into bounded sessions:

# Session 1: Auth module only
cd src/auth && claude

# Session 2: Payment module only  
cd src/payments && claude
Enter fullscreen mode Exit fullscreen mode

Each session starts fresh with a small context. No rate limits from accumulated history.

Fix 6: Use CLAUDE.md to avoid re-explaining

If you're re-explaining your codebase every session, you're burning tokens on context-building:

# CLAUDE.md
## Architecture
- Next.js 14 app router
- PostgreSQL via Prisma
- Stripe for payments
- Auth via NextAuth v5

## Conventions
- All API routes in /app/api/
- DB queries in /lib/db/
- Never use any, always type everything
Enter fullscreen mode Exit fullscreen mode

Claude reads CLAUDE.md automatically at session start. No more re-explaining = fewer tokens burned.

The real solution for heavy users

If you're hitting rate limits regularly, it means you're using Claude Code heavily enough that the per-API limits are genuinely constraining you. The right fix is a proxy that handles limits at the infrastructure level.

# Set once in your .bashrc or .zshrc
export ANTHROPIC_BASE_URL=https://simplylouie.com/api/proxy

# Now claude works without rate limit interruptions
claude
Enter fullscreen mode Exit fullscreen mode

This is the workflow for developers who use Claude Code as their primary coding environment, not just occasionally.
