Novita Agent Sandbox alternatives
The 6 alternatives below are grouped by kind of sandbox, and each says what it does differently from Novita Agent Sandbox. Start from whatever made you look: missing GPUs, session limits, self-hosting, pricing or isolation.
Why teams look beyond Novita Agent Sandbox
An inexpensive, well-documented lifecycle on an undocumented isolation boundary, best for cost-sensitive US workloads.
- Isolation technology is not documented
- US regions only
- No documented network allow/deny controls
- Free tier limited to 1-hour sessions and 5 concurrent sandboxes
Novita Agent Sandbox alternatives, by kind
Hosted sandbox platforms
SDK-driven sandboxes you create, run code in and destroy through an API.
Blaxel
Perpetual microVM sandboxes for AI agents that drop to standby when idle and resume with memory intact, plus volumes, batch jobs and MCP hosting.
- MicroVM
- BYOC
- Pause/resume
How it differs: Always-available agents that sit idle most of the time and need near-instant resume. A strong design for always-on, mostly-idle agents; watch how the Baseten acquisition shapes the roadmap.
Cloudflare Sandbox SDK
A TypeScript SDK for Cloudflare Workers that runs untrusted code in Linux sandboxes backed by Cloudflare Containers and Durable Objects.
- MicroVM (Containers)
- Open source
- Snapshots
How it differs: Teams building on Cloudflare Workers that want per-user sandboxes with egress and credentials controlled in code. A strong, programmable option for Workers developers; less suited to Python-first agent stacks.
Daytona
Stateful sandboxes for AI-generated code — Linux containers, Linux and Windows VMs, macOS and GPU sandboxes — with snapshots, volumes and preview URLs.
- Containers or VMs
- BYOC
- GPU
- Pause/resume
How it differs: Long-lived, stateful agent workspaces that need many SDK languages, GPUs, or Windows and macOS sandboxes. The strongest choice for stateful coding-agent workspaces and breadth of sandbox types; note the shift away from open source.
E2B
Open-source cloud sandboxes for AI agents, each a Firecracker microVM, with pause/resume, snapshots and forking.
- Firecracker microVM
- Open source
- Self-hostable
- BYOC
- Pause/resume
How it differs: Code interpreters and short-to-medium-lived agent tasks that need microVM isolation, with an open-source self-host path. The safe default for most agent builders: mature, open source, microVM-isolated and widely supported.
HopX
Firecracker microVM sandboxes from Bunnyshell with template-based sizing, memory-preserving pause, VNC desktop automation, an MCP server and $200 of free credits.
- Firecracker microVM
- Pause/resume
How it differs: Pay-per-second microVM sandboxes with desktop automation and no session limits. A simple per-second Firecracker sandbox with desktop tooling, documented more thinly on security and regions than its larger peers.
Compute platforms with sandboxes
General serverless or app platforms that also offer sandboxes, often with GPUs.
Beam Sandboxes
Serverless AI compute platform whose sandboxes are gVisor-isolated containers with memory snapshots, optional GPUs and an open-source, self-hostable runtime.
- gVisor
- Open source
- Self-hostable
- BYOC
- GPU
- Pause/resume
How it differs: Teams that want an open-source, self-hostable sandbox runtime with GPU access. A cost-effective GPU sandbox with an open runtime; best for trusted or semi-trusted code.
