InstaBox: Free Cloud Sandboxes for AI Agents — Honest Notes After a Week of Testing

说明与用途

InstaBox 为 AI 代理提供免费云沙箱，支持浏览器自动化和网络实验，并提供持久存储，但受限于空闲暂停、最长 8 小时运行时间以及无公共 IPv4。

问题

Running AI agent browser automation locally limits persistence, scalability, and remote accessibility.

结果

InstaBox provides a free, persistent cloud sandbox for AI agents, enabling browser automation and network experiments without local machine constraints, though it is limited to short-term use and lacks public inbound IPs.

工作流

• 1. Join the InstaBox beta and activate the Free plan.
• 2. Spin up to 5 machines (4 vCPU / 8 GiB RAM / 20 GiB disk each).
• 3. Deploy AI agent code to the machine.
• 4. Use the provided HTTPS links or SSH gateway to interact with services.
• 5. Let the machine pause after ~30 minutes idle or stop after ~8 hours continuous run.

证据

InstaBox (instabox.sh), built by InsForge, is a cloud sandbox service made for AI agents — instead of running agent browser/automation work on your own machine, you spin up cloud machines and let the agent work there.

Up to 5 machines; the agent-browser template is 4 vCPU / 8 GiB RAM / 20 GiB disk per machine

来源

Files live on a persistent volume and survive pause, shutdown and reboot (only deleting the machine wipes them)

来源

Machines auto-pause after ~30 minutes idle, and there is a max continuous run of ~8 hours — it is a workbench, not a 24/7 server

来源

As a free workbench for AI-agent experiments, I have not found anything else like it.
