Here's a sampling of stuff I've semi-recently encountered on Github that all spy on you by default. For some, it's undocumented, for others it's a minor subsection in the docs. (Some of them are source-available not free, I didn't keep track as I collected the URLs.) https://github.com/zed-industries/zed https://github.com/microsoft/vscode https://github.com/keystonejs/keystone https://github.com/meilisearch/meilisearch https://github.com/hasura/graphql-engine https://github.com/manticoresoftware/manticoresearch/ https://github.com/coder/code-server https://github.com/loft-sh/devpod https://github.com/quickwit-oss/quickwit https://github.com/rilldata/rill-developer/ https://github.com/hocus-dev/hocus https://github.com/firezone/firezone Here's a write-up of how bad it gets -- it's pretty obnoxious: https://www.roboleary.net/tools/2022/04/

I didn't want to go into all the technical details, but we have another write-up that goes into details about RAM management: https://github.com/hocus-dev/hocus/blob/main/rfd/0003-worksp... Other than making sure we release unused memory to the host, we didn't customize QEMU that much. Although we do have a cool layered storage solution - basically a faster alternative to QCOW2 that's also VMM independent. It's called overlaybd, and was created and implemented in Alibaba. That will probably be another blog post. https://github.com/containerd/overlaybd

We do, and we'd love to use it in the future. We've found that it's not ready for prime time yet and it's missing some features. The biggest problem was that it does not support discard operations yet. Here's a short writeup we did about VMMs that we considered: https://github.com/hocus-dev/hocus/blob/main/rfd/0002-worksp...

If you’d rather use a self-hosted alternative, we are building Hocus [0]. It’s still in alpha, but already supports prebuilds, VSCode, shared environment variables, and more. [0] https://github.com/hocus-dev/hocus
