Sandbox-agent: Remote Control Server for Coding AI Agents via HTTP
By
NathanFlurry
A baker's-dozen of insight crammed into one ring.
Summary
Sandbox-agent is a server tool that enables remote control of coding AI agents (Claude Code, Codex, OpenCode, Cursor, Amp, Pi) within sandboxed environments via HTTP. It solves challenges with existing SDKs that assume local execution, SSH issues with TTY handling, and inconsistent APIs across different coding agents. The tool provides streaming events, permission management, session handling, and includes experimental features like Gigacode for using OpenCode's TUI with any coding agent.

· 4 pulledRun Coding Agents in Sandboxes. Control Them Over HTTP.
Running coding agents remotely is hard. Existing SDKs assume local execution, SSH breaks TTY handling and streaming, and every agent has a different API.
A server that runs inside your sandbox. Your app connects remotely to control Claude Code, Codex, OpenCode, Cursor, Amp, or Pi — streaming events, handling permissions, managing sessions.
Experimental: Gigacode — use OpenCode's TUI with any coding agent.
