Tensorlake Sandboxes alternatives
The 6 alternatives below are grouped by kind of sandbox, and each says what it does differently from Tensorlake Sandboxes. Start from whatever made you look: missing GPUs, session limits, self-hosting, pricing or isolation.
Why teams look beyond Tensorlake Sandboxes
A feature-rich microVM platform for agent harnesses at scale, with open-source and BYOC options that most hosted peers lack.
- Hypervisor is not named in the docs
- GPU sandboxes are by request only and use gVisor rather than a VM
- No published region list
- Free plan allows one 1 vCPU sandbox with 2-hour sessions
Tensorlake Sandboxes 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.
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.
Persistent VMs and agent computers
Full, long-lived virtual machines that an agent keeps, forks and returns to.
Morph Cloud
VM-based cloud computers for AI agents built on “Infinibranch” snapshot, branch and restore, plus persistent Devboxes.
- VM
- Pause/resume
How it differs: Workloads that branch a running environment many times — parallel search, RL and evaluation rollouts. Purpose-built for branching workloads; a specialist pick for search, RL and evals.
Compute platforms with sandboxes
General serverless or app platforms that also offer sandboxes, often with GPUs.
Modal Sandboxes
Sandboxes on Modal’s serverless compute platform for running untrusted code at very high scale, with GPUs, snapshots and tunnels.
- gVisor or VM
- GPU
- Pause/resume
How it differs: High-concurrency and GPU-backed sandboxes — RL rollouts, evals and coding agents at scale. The best fit when scale or GPUs matter most, especially for teams already on Modal.
Namespace
Isolated Linux, macOS and Windows VM instances and persistent Devboxes on a developer-compute cloud, with an SDK, egress policy and SOC 2 Type II.
- KVM virtual machine
- Pause/resume
How it differs: Teams that want macOS, Windows and Linux VMs for agents and CI from one SDK, plus persistent Devboxes for coding agents. A CI-grade compute cloud whose VMs and Devboxes suit teams needing macOS or Windows and compliance more than minimal per-sandbox cost.
