We’ve been working with automating coding agents in sandboxes as of late. It’s bewildering how poorly standardized and difficult to use each agent varies between each other.

We open-sourced the Sandbox Agent SDK based on tools we built internally to solve 3 problems:

1. Universal agent API: interact with any coding agent using the same API

2. Running agents inside the sandbox: Agent Sandbox provides a Rust binary that serves the universal agent API over HTTP, instead of having to futz with undocumented interfaces

3. Universal session schema: persisting sessions is always problematic, since we don’t want the source of truth for the conversation to live inside the container in a schema we don’t control

Agent Sandbox SDK has:

- Any coding agent: Universal API to interact with all agents with full feature coverage

- Server or SDK mode: Run as an HTTP server or with the TypeScript SDK

- Universal session schema: Universal schema to store agent transcripts

- Supports your sandbox provider: Daytona, E2B, Vercel Sandboxes, and more

- Lightweight, portable Rust binary: Install anywhere with 1 curl command

- OpenAPI spec: Well documented and easy to integrate

We will be adding much more in the coming weeks – would love to hear any feedback or questions.
