Sandbox Agent SDK: One HTTP API to Control Claude Code, Codex, and Every Other Coding Agent
Rivet’s open-source Sandbox Agent SDK normalizes the APIs of Claude Code, Codex, OpenCode, Amp, and Cursor behind a single HTTP/SSE interface. A 15MB Rust binary runs inside any sandbox provider (E2B, Daytona, Docker, Vercel) and exposes standardized session management, event streaming, and permission handling. This post covers the architecture, supported agents, real-world deployment patterns, and how it compares to building direct integrations.
