# Best AI Agent Sandboxing Tools 2026

## TL;DR

The best AI agent sandboxing tools in 2026 isolate generated code, shell commands, files, package installs, browser work, and long-running agent sessions from your host system. E2B is the safest default for AI code-interpreter products; Modal wins for Python, ML, batch, and GPU workloads; Daytona and CodeSandbox fit full development environments; Blaxel targets low-latency stateful agents; Northflank fits enterprise/BYOC deployment; Cloudflare Sandbox SDK and OpenAI Sandbox Agents are best inside their own ecosystems.
