Software engineering has entered the agentic era. Tools like Cursor IDE, Claude Code CLI, Cline, and Windsurf make writing code 10x faster. But as anyone running autonomous agents knows, token bills add up quickly. A single refactoring loop or bug reproduction can easily burn 300,000+ tokens.

At standard Anthropic rates ($3/M input and $15/M output for Claude 3.5 Sonnet), software engineers easily rack up $100 to $300 every month on personal credit cards.

Recently, two open-source projects have gained viral traction in the developer community:

  1. tashfeenahmed/freellmapi (38.6k stars): Aggregates 34 free provider tiers and pools 635 model endpoints behind a single OpenAI/Anthropic /v1 endpoint, managing 7.4 billion tokens per month.
  2. diegosouzapw/OmniRoute (79.1k stars): A high-performance AI gateway that dynamically routes prompts to free high-speed models (Llama 3.3 70B, DeepSeek V3, Qwen 2.5 Coder 32B) and fails over seamlessly in under 15 milliseconds.

1. The Multi-Provider Routing Architecture

Major cloud providers (Cerebras, Groq, Cloudflare Workers AI, GitHub Models, Together AI, HuggingFace) offer generous free developer tiers:

  • Cerebras: Up to 1M free tokens/day at 1,800 tokens/second.
  • Groq Cloud: Free high-speed Llama 3.1 & 3.3 inference with zero latency.
  • GitHub Models / Azure: Free developer tier with GPT-4o-mini and Claude-compatible routing.

The bottleneck has always been managing 30+ separate API keys, diverse SDK specifications, and sudden HTTP 429 rate limits.

FreeLLMAPI and OmniRoute solve this with a 3-tier proxy:

  1. Smart Model Mapping: When your IDE asks for claude-3-5-sonnet, OmniRoute maps it to the best available free reasoning model (e.g., DeepSeek R1/V3 or Qwen 2.5 Coder 32B).
  2. Dynamic Failover: If Provider A returns a 429 rate limit or 503 gateway timeout, the proxy retries on Provider B within 15 milliseconds.
  3. Zero IDE Interruptions: Your editor never encounters connection crashes.

2. Quickstart with Docker Compose

You can launch the complete gateway locally in less than 2 minutes:

# 1. Clone the repository git clone https://github.com/tashfeenahmed/freellmapi.git cd freellmapi # 2. Setup your environment cp .env.example .env # 3. Spin up the container docker compose up -d

The gateway will now be live on http://127.0.0.1:8000/v1.

3. Connecting to Cursor IDE & Claude Code CLI

A. Cursor IDE

  1. Open Cursor Settings > Models.
  2. Turn on OpenAI API Key and enter any string (e.g. sk-free-token-2026).
  3. Set Override OpenAI Base URL to: 
http://127.0.0.1:8000/v1
  1. Add model names: claude-3-5-sonnet-20241022, deepseek-chat, or qwen-2.5-coder-32b.

B. Claude Code CLI

In your PowerShell or Bash terminal:

# PowerShell $env:ANTHROPIC_BASE_URL="http://127.0.0.1:8000/v1" ; claude # Bash / Zsh export ANTHROPIC_BASE_URL="http://127.0.0.1:8000/v1" claude
