What we found

MXC
github.com

A sandboxed code-execution system; commenters praise permission discovery and agent-harness integration.

Source discussion: MXC - a sandboxed code execution system

“I like the ‘learning’ mode for figuring out what perms/config a runtime needs, the MIT license, the clear optional telemetry disclosures, and somewhat light and still readable documentation.”

“I agree! I can't comment on the design of the SDKs but from the looks of it this is a great option to integrate into agent harnesses/pipelines. The "audit" and "debug" mode are specially useful.”

“It's very handy (I find myself reaching for it as if it's a built-in) and I appreciate its design (I learned a few things reading it)!”

exe.dev
Seen 2 times
exe.dev

Persistent Linux VMs for development; a user keeps worktrees and preview sites running.

Source discussion: Ask HN: What do you run on a $5 VPS that's worth keeping online 24/7?

“Checking out a git repo in a Linux VM and hosting prod elsewhere (automatically deployed via a push to GitHub) seems like a nice pattern. Since exe.dev doesn’t charge anything to leave the dev machines running, I leave them running.”
