FreeRouter AI is a lightweight, on-device smart AI proxy and router designed for developers, researchers, and creators. Route prompts from coding assistants, IDEs, and SDKs to optimal AI models in millisecondsβcutting API bills by 60% to 80% with zero quality loss.
WHY FREEROUTER AI?
Every AI query is different. Why pay maximum flagship prices for simple questions, boilerplate code, or quick summaries? FreeRouter AI evaluates prompt intent in single-digit milliseconds on your device and routes each request to the best model tier:
β‘ Instant Fast Tier: Handles simple lookups, formatting, and routine queries via lightning-fast, ultra-low-cost models (DeepSeek Chat, Claude 3.5 Haiku, GPT-4o Mini, Gemini Flash).
π§ Standard Code & Creation Tier: Routes programming tasks, code reviews, and reasoning prompts to top-performing models (Claude 3.5 Sonnet, GPT-4o, Gemini 1.5 Pro).
π¬ Deep Reasoning Tier: Directs complex mathematical proofs, deep logic, and architecture planning to frontier reasoning models (DeepSeek R1, OpenAI o1/o3, Claude Opus).
Key Features
β’ 1-Click Local Proxy Server: Runs entirely on your Android device. Connect over USB or local Wi-Fi LAN with zero latency.
β’ Seamless IDE & Client Compatibility: Drop-in replacement for Cursor, Claude Code, Cline, Roo Code, Continue.dev, and standard OpenAI / Anthropic SDKs.
β’ Automatic Fallback Chains: Never encounter API downtime. If a provider is rate-limited (429) or unreachable, FreeRouter instantly retries with your backup model chain.
β’ Universal Provider Support: Works with Anthropic Claude, OpenAI, DeepSeek, Google Gemini, Groq, Mistral, Moonshot Kimi, OpenRouter, and local offline models via Ollama & vLLM.
β’ Zero Cloud Data Storage: Your prompts, API keys, and configurations remain 100% on your device. FreeRouter does not operate external proxy servers or log user prompts.
β’ Real-Time Savings Tracker: Monitor real-time request counts, response latency, and dollar savings saved on every routed token.
β’ Built-In AI Playground: Test provider keys and prompt latency directly inside the app with rich Markdown rendering and voice input.
β’ Encrypted Backup & Restore: Safeguard your custom provider endpoints and configurations with password-protected AES-256-GCM encryption.
