Sandbox as a Service A Chutes.ai project
Isolated sandboxes for running Agents and LLM generated code. Safe. Scaleable. Affordable.

Ultra-fast, production-grade sandboxes for safe, scalable AI execution. Run untrusted code without slowing agents.

Spin up isolated sandboxes in seconds, run code safely, and pay a fraction of typical prices. Designed for AI agents, build systems, and modern dev teams that refuse to overpay.

Why Sandy

Two core workflows need isolated execution.

Sandy protects both AI-generated code and autonomous agents at scale.

LLM-generated code must run safely

Models can produce helpful code, but they can also introduce risk. Sandy keeps execution isolated, captures output, and prevents surprises in production.

YOLO agents need safe autonomy

Agents are most efficient when they can run without constant approvals. By giving each agent a hardened sandbox, Sandy unlocks YOLO mode while staying secure and scalable.

LLM generated code isolated by Sandy

Create a sandbox in one call, stream output, and terminate cleanly.

Platform

Build faster with a modern sandbox stack.

Sandy is purpose-built for AI coding workflows and massive parallel test runs. Every sandbox includes deterministic build environments, shared caches, and low-latency IO.

Instant isolation

Launch hardened sandboxes in seconds, each with strict resource limits and clean workspaces.

  • Per-sandbox CPU/RAM limits
  • File operations + exec streaming
  • Fast terminate + cleanup

Shared cache plane

Reuse dependencies and datasets across sandboxes. Dramatically cut build times and bandwidth.

  • Read-only cache mounts
  • Explicit cache fetch API
  • Host-level cache budgets

Agent-ready runtime

Run CLI agents, compilers, and browsers inside the sandbox without fragile orchestration.

  • Streaming agent API
  • Built-in Playwright runtime
  • Zero-trust network defaults

Get running in 5 minutes

  1. Create your Sandy API key
  2. Spin up a sandbox with one request
  3. Exec code, stream output, terminate

Works with your existing LLM pipeline and CI tools.

API sample 2 requests 
curl -X POST https://sandy.sandbox-as-a-service.com/api/sandboxes \
  -H \"Authorization: Bearer $SANDY_API_KEY\" \
  -d '{\"enable_docker_socket\": false}'

curl -X POST https://sandy.sandbox-as-a-service.com/api/sandboxes/sb_72b4/exec \
  -H \"Authorization: Bearer $SANDY_API_KEY\" \
  -d '{\"command\": \"node --version\"}'

API docs

Everything is a simple HTTP call.

Authenticate once, spin up sandboxes, stream output, and ship.

Authentication

Send your Sandy API key as a bearer token on every request.

Authorization: Bearer $SANDY_API_KEY

Core endpoints

  • POST /api/sandboxes
  • POST /api/sandboxes/:id/exec
  • GET /api/sandboxes/:id/events
  • POST /api/sandboxes/:id/terminate

Lifecycle

  1. Create a sandbox with your runtime settings
  2. Run commands, stream logs, pull artifacts
  3. Terminate the sandbox and clean up

Advantage

Massive cost advantage, predictable performance.

Sandy runs on dedicated, optimized infrastructure. We pass the savings directly to teams that want reliable sandboxes at scale.

Security

Isolation-first, designed for production workloads.

Every sandbox is locked down by default. You can opt into elevated permissions only when you need them.

Hardened by default

CAP drop, no-new-privileges, and strict resource controls.

Zero trust networking

Outbound controls, per-sandbox host suffixes, and private ingress routing.

Full audit trail

Telemetry events stored in Postgres with export-ready history.

FAQ

Questions teams ask before switching.

How fast can I start a sandbox?

Cold start is typically 2-4 seconds. Prewarming can reduce this further.

Do you support Playwright and browsers?

Yes. The runtime ships with optional Playwright + Chromium builds.

Can we bring our own Docker images?

Yes. Enterprise plans support custom runtime images and internal registries.
