What is a coding proxy?

A coding proxy sits between an AI coding tool — Claude Code, Cursor, Cline, or an IDE plugin — and the model providers behind it, speaking the same OpenAI- or Anthropic-compatible API. It lets you swap in a different or cheaper model, pool many API keys, and enforce spend limits without changing the assistant itself. Many also log, cache, and rate-limit every request that passes through.

What coding proxies do

  • Drop-in OpenAI- or Anthropic-compatible API endpoint
  • Route requests to any model or provider
  • Aggregate and rotate multiple API keys
  • Per-key budgets, quotas, and rate limits
  • Request logging, caching, and usage dashboards
  • Fallback and load-balancing across backends

Who uses a coding proxy

01

Cut model costs

Point Claude Code or Cursor at cheaper models to lower per-token spend on the same workflow.

02

Self-hosted key gateway

Teams centralize provider keys behind one endpoint with quotas, rotation, and audit logs.

03

Access blocked models

Reach a model or provider through a relay when it is unavailable in your region or account.

04

Observe and debug agents

Inspect prompts, tokens, and latency for every call an AI coding agent makes.

How a coding proxy works

You point your coding assistant at the proxy's base URL instead of the provider's, using a key the proxy issues. The proxy receives each request, picks a backend model and real API key by your rules, forwards it, and streams the response back unchanged. Along the way it can log the call, count tokens, cache repeats, and retry on a different provider if one fails.
