AgentBay alternatives
The 6 alternatives below are grouped by kind of sandbox, and each says what it does differently from AgentBay. Start from whatever made you look: missing GPUs, session limits, self-hosting, pricing or isolation.
Why teams look beyond AgentBay
The broadest environment mix of the cloud-native options, with transparent compute pricing, but an undocumented isolation layer.
- Isolation technology is not documented
- Sessions default to a 30-minute maximum and lose all data on release unless Contexts are configured
- Compliance certifications and GPU support are not documented; pause/resume and Context Mount are beta or whitelist-only
- Account prerequisites (Alibaba Cloud account, trial not available to RAM users) add friction outside China and Southeast Asia
AgentBay alternatives, by kind
Hosted sandbox platforms
SDK-driven sandboxes you create, run code in and destroy through an API.
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.
Cloud provider code execution
Managed code-execution tools from AWS, Azure, Google Cloud and OpenAI.
AWS Bedrock AgentCore
AWS’s managed agent platform: a Code Interpreter tool for running agent-generated code and a Runtime that hosts each agent session in its own microVM.
- MicroVM (Runtime)
How it differs: Teams already on AWS that need IAM- and VPC-integrated code execution for agents. The natural default for AWS-centric teams; less attractive if you want portability or a provider-neutral SDK.
Browser and desktop sandboxes
Hosted browsers and full desktops that computer-use agents click, type and browse in.
Browserbase
Hosted headless Chromium sessions for web agents, driven over CDP with Playwright, Puppeteer, Selenium or the Stagehand SDK, with Contexts for persisted logins and four regions.
- Isolated Chromium session
How it differs: Web agents that need managed Chromium at scale with persisted logins and stealth. A mature managed-Chromium service for web agents, with strong SDK and framework coverage but an undocumented isolation boundary.
Cua
Open-source computer-use infrastructure: Linux sandboxes as gVisor containers and macOS or Windows sandboxes as VMs, run locally, in your own cloud account or as shared "Spaces".
- gVisor container or VM
- Open source
- Self-hostable
- Pause/resume
How it differs: Teams that want open-source computer-use sandboxes on their own Macs, servers or cloud accounts, including macOS VMs on Apple silicon. The broadest open-source option for computer-use sandboxes across macOS, Linux and Windows, now firmly a self-run toolkit after the hosted cloud shut down.
Scrapybara
Hosted Ubuntu, browser and Windows desktop instances for computer-use agents, driven through Python and TypeScript SDKs with pause and resume.
- Not documented
- Pause/resume
How it differs: Computer-use agents that need a ready-made Ubuntu or Windows desktop with a browser, bash, filesystem and Jupyter tools in one API. A compact computer-use desktop API with good tooling, but undocumented isolation and pricing and a parent company that has pivoted make it one to evaluate carefully.
Open-source runtimes to self-host
Open-source sandbox runtimes you run on your own servers or Kubernetes.
OpenSandbox
Apache-2.0 sandbox runtime for agents that starts on Docker, scales on Kubernetes and offers a Firecracker "Fast Sandbox" with pause/resume.
- Containers or Firecracker
- Open source
- Self-hostable
- Pause/resume
How it differs: Teams that want an open, multi-language sandbox API they can run from a laptop Docker daemon up to a Kubernetes cluster. The most broadly supported open sandbox API of this batch, with real microVM isolation available once you are on Kubernetes.
