We’re building Windows virtual machines that can be operated by computer-use agents (CUAs). You can spin up persistent Windows instances in seconds and operate them with CUAs. We’ve created a built-in agent, or you can plug in your own with the API + SDK.

Skylight works best to automate apps and legacy software that don’t have APIs, such as Microsoft Office and ERP systems.

We built this because deploying CUAs in production is way harder than it should be, and we packed in all the things we needed 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

If you need to run agents that use desktop software (not just browsers), come check us out (for free).
