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.

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

Your Claude Pro/Max subscription in any tool — Cursor, Cline, Aider, Agent SDK — at subscription pricing, not per-token bills. One local endpoint that replays Claude Code's wire shape so your traffic stays in the subscription pool.

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 self-improving LLM router that optimize your agentic workflows with every runs, 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.
