Windows Virtual Machines for Computer-Use Agents

Free2,571 impressions#8 of its week

Skylight builds and hosts virtual Windows computers that can be operated by computer-use agents. You can spin up a persistent Windows instance in seconds and run an agent to automate any desktop apps, including Microsoft Office, ERP systems, EHR software, or any legacy software that runs on Windows. We integrated in a custom agent that hits SOTA performance, or you can plug in your own using our API + SDK. We're a team of DeepMind Scholar + PhD AI engineers who built this because we found it weirdly hard to deploy CUAs in production. We included the features we wanted for ourselves: - Persistence – pause and resume VMs without losing progress - Interactive Live Streaming – watch agents work in real time and take control if needed - Multiple Instances – run multiple VMs at once and coordinate across them - File Downloads – pull files from VMs to your local machine - Knowledge Base – agents retain context of past actions - Human-in-the-Loop – guardrails for important and irreversible actions To start your first Windows WM, run (in Python): pip install skylight-sdk from skylight_sdk import Skylight skylight = Skylight(apikey="your_api_key") instance = skylight.windows.start() For Typescript and SDK + API Reference, check out the docs: https://docs.launchskylight.com/introduction HN devs - would love honest feedback on the SDK/API design and whether this solves your Windows VM pain points.

Skylight provides on-demand virtual Windows machines that can be controlled by AI agents via API/SDK.

Skylight FAQ

How do I start a Windows instance?+

Install the skylight-sdk, create a Skylight object with your API key, and call skylight.windows.start().

Can I use my own AI agent?+

Yes, you can plug in your own agent via the API/SDK or use Skylight’s built-in agent.

What happens to a VM when I pause it?+

The instance is hibernated; you can resume later without losing progress.

Is there a cost for idle VMs?+

Active computers cost $0.005 per minute, hibernated computers $0.0005 per minute.

How are destructive actions handled?+

The human-in-the-loop guardrail requires user confirmation before irreversible steps.

What support is available on the free tier?+
