Alternatives to Depot's remote agent sandboxes

Depot's remote agent sandboxes offer persistent cloud environments with Git integration designed for AI coding tools like Claude Code, focusing on productivity while lacking robust security features for untrusted workloads. Alternatives to Depot include Northflank, which provides production-grade microVMs with enterprise features and supports multiple languages, and GitHub Codespaces, which offers native GitHub integration but is limited to the GitHub ecosystem. Modal is optimized for Python-based machine learning tasks with serverless architecture, while E2B.dev and Vercel Sandbox focus on quick, isolated AI agent execution with Firecracker microVMs. Depot's sandboxes are beneficial for specific Claude Code workflows but are not suitable for secure, multi-tenant runtime environments, making Northflank a more comprehensive solution for production applications requiring higher security and persistence.
