Franklin

Franklin is an open-source, wallet-native AI agent that combines autonomous task execution with real spending power. Unlike traditional coding agents, Franklin holds a USDC wallet, selects the best model per task from 55+ providers, and pays for APIs, data, images, and web search — all autonomously. Built in TypeScript under the Apache 2.0 license, it ships as a single npm package with zero signup, zero credit card, and zero KYC required.

Franklin introduces the YOPO (You Only Pay Outcome) pricing model: you pay provider cost + 5% per action settled in USDC, with no monthly fees, no rate limits, and no overdraft — your wallet balance is the hard cap. Every paid action routes through the x402 micropayment protocol and settles against your own non-custodial wallet on Base or Solana.

Key features include:

• Smart Router — Trained on 2M+ real requests, the router classifies every task (coding, trading, reasoning, research) and selects the optimal model from 55+ LLMs including Anthropic, OpenAI, Google, xAI, DeepSeek, and NVIDIA free-tier models. Four profiles: auto, eco, premium, and free.
• YOPO Micropayments — HTTP 402 native payments via EIP-712 signed USDC micropayments. Non-custodial; your keys never leave your machine. No subscriptions, no rate limits, no overdraft.
• 16+ Built-in Tools — Read, Write, Edit, Bash, Glob, Grep, WebFetch, WebSearch, Task, ImageGen, VideoGen, MemoryRecall, AskUser, SubAgent, TradingSignal, TradingMarket, TradingPortfolio, and more.
• Trading Signals — Fetches live crypto price data and computes RSI, MACD, Bollinger Bands, and volatility locally via CoinGecko. No API key needed.
• AI Image & Video Generation — Calls DALL-E / GPT Image directly from the CLI or VS Code extension, paid from your wallet.
• Persistent Sessions — Every turn is streamed to disk with metadata. Resume any session by ID; survives crashes and reboots.
• Telegram Remote Control — Run Franklin on an always-on machine and drive it from your phone via a Telegram bot, with session resumption and slash commands.
• VS Code Extension — The same agent ships as a VS Code extension with a chat panel, model picker, wallet balance display, and inline diff cards.
• Plugin SDK + MCP — Extend Franklin with new workflow verticals via the plugin SDK or discover external tools automatically through MCP server auto-discovery.
• Cost Insights — franklin insights provides spend breakdowns, trends, and projections per model and task category.
• Free Tier — Start with zero dollars using free NVIDIA models (Qwen3 Coder + Llama 4 Maverick) with no wallet funding required.
