 1. **Coding agents need sandboxes** — You can't let AI execute arbitrary code on your production servers. Coding agents need isolated environments, but existing SDKs assume local execution. Sandbox Agent is a server that runs inside the sandbox and exposes HTTP/SSE.
 
-2. **Every coding agent is different** — Claude Code, Codex, OpenCode, and Amp each have proprietary APIs, event formats, and behaviors. Swapping agents means rewriting your integration. Sandbox Agent provides one HTTP API — write your code once, swap agents with a config change.

 3. **Sessions are ephemeral** — Agent transcripts live in the sandbox. When the process ends, you lose everything. Sandbox Agent streams events in a universal schema to your storage. Persist to Postgres, ClickHouse, or [Rivet](https://rivet.dev). Replay later, audit everything.

 - **Streaming Events**: Real-time SSE stream of everything the agent does — tool calls, permission requests, file edits, and more
 - **Universal Session Schema**: [Standardized schema](https://sandboxagent.dev/docs/session-transcript-schema) that normalizes all agent event formats for storage and replay
 - **Human-in-the-Loop**: Approve or deny tool executions and answer agent questions remotely over HTTP
