Sled is a voice interface that allows developers to interact with their coding agents remotely from their phones. It solves the problem of coding agents sitting idle when developers step away from their desks by providing voice-based communication that works securely over tunneling services.

Sled provides notifications when your agent finishes a task or hits a wall, telling you what happened. It offers voice input that handles camelCase and function names, and voice output with 300+ voices to choose from. The system works away from your desk, supports hands-free operation with AirPods, keeps code local on your machine, uses secure tunneling with ngrok or Tailscale, and is fully open source.

Sled works by transcribing your voice input and sending it to your agent over a secure tunnel. Your coding agent runs locally on your computer, ensuring code never leaves your machine. Responses are then converted to speech so you can hear what the agent accomplished.

The main benefit is enabling developers to continue coding while away from their desks - on the couch, in bed, or walking around. It provides hands-free operation where you can keep your phone in your pocket and AirPods in without needing to look at a screen.

Sled targets developers who use coding agents like Claude Code, OpenAI Codex, and Gemini CLI. It requires ngrok or Tailscale for mobile access and is designed as experimental software that developers can fork, modify, and self-host.
