Note: This is the Vercel-optimized version of the sandbox-coding-agent example. It uses the hono/vercel adapter and is configured for Vercel deployment.

Sandbox Coding Agent

Example project demonstrating a Rivet Actor chat UI backed by the new rivetkit/sandbox actor.

Getting Started

git clone https://github.com/rivet-dev/rivet.git
cd rivet/examples/sandbox-coding-agent-vercel
pnpm install
pnpm dev

Features

• Uses rivetkit/sandbox instead of constructing SandboxAgent clients directly
• One sandbox actor per agent key
• Built-in transcript persistence through the sandbox actor
• Provider selection with SANDBOX_PROVIDER=docker|daytona|e2b
• Live UI updates via Rivet Actor events

Prerequisites

• On Vercel, use SANDBOX_PROVIDER=daytona or SANDBOX_PROVIDER=e2b
• For Daytona, set DAYTONA_API_KEY
• For E2B, set E2B_API_KEY
• Set the model provider credentials needed inside the sandbox, such as OPENAI_API_KEY, ANTHROPIC_API_KEY, or CODEX_API_KEY

Implementation

The example keeps a thin UI-facing agent actor, but the sandbox lifecycle and sandbox-agent API now live behind sandboxActor(...).

• Sandbox actor integration (src/actors.ts)
• Frontend orchestration (frontend/App.tsx)
• Server entry point (src/server.ts)
