List of Permanent Free LLM API (API Keys)

Open-source LLM router & AI cost optimizer. Routes simple prompts to cheap/local models, complex ones to premium — automatically. Drop-in OpenAI-compatible proxy for Claude Code, Codex, Cursor, OpenClaw. Saves 40-70% on AI API costs. Self-hosted, no middleman.

Streamline your workflow with Lynkr, a CLI tool that acts as an HTTP proxy for efficient code interactions using Claude Code CLI.

A local OpenAI- and Anthropic-compatible proxy that brings your Claude Pro/Max subscription to Cursor, Cline, Aider, and the Agent SDK. Session-affinity routing, multi-account pooling, and live drift detection keep long agent runs stable across tools.

Route LLM requests to the best model for the task at hand.

High-performance lightweight proxy and load balancer for LLM infrastructure. Intelligent routing, automatic failover and unified model discovery across local and remote inference backends.

The model router that continuously improve your agentic workflows, works with any harnesses, any models, any loops.

Open-source AI gateway for local agent clients: publish fusion-style multi-model workflows as OpenAI/Claude-compatible virtual models with traces, tokens, latency, and cost visibility.

Self-hosted AI Gateway — connect Claude Code, Codex, Gemini CLI and any SDK to any model provider with protocol translation.

SmarterRouter: An intelligent LLM gateway and VRAM-aware router for Ollama, llama.cpp, and OpenAI. Features semantic caching, model profiling, and automatic failover for local AI labs.

Unified management and routing for llama.cpp, MLX and vLLM models with web dashboard.

Intelligent multi-LLM router with task-aware routing strategies, cost optimization, and production safety controls — drop-in OpenAI-compatible API

RouterArena: An open framework for evaluating LLM routers with standardized datasets, metrics, an automated framework, and a live leaderboard.

Route inference across providers.

Free, self-hosted AI model router. OpenRouter / ClawRouter alternative using your own API keys. 14-dimension classifier routes to the right model (Anthropic/OpenAI/Kimi) automatically. No middleman, no markup. Built for OpenClaw.

Open-source AI gateway for LLMs & AI agents, built in Rust. One OpenAI-compatible API for OpenAI, Anthropic, Gemini, Bedrock & more — routing, guardrails, caching, rate limits, observability.

⚡ Awesome AI Gateway — pick an AI gateway from 100+ (LiteLLM, OpenRouter, Portkey, Kong, Higress, new-api, Bifrost) by cost, security & compliance, learn how they actually work from an 8-chapter handbook, and verify every number yourself. Reproducible benchmarks, bilingual, updated daily.

A self-hosted LLM proxy and failover gateway supporting OpenAI & Gemini compatible endpoints. Routes requests dynamically across 12+ LLM platforms with automatic fallback, key scheduling, rate-limit tracking and encrypted credential storage.
