Obscura
The open-source headless browser for AI agents and web scraping. Lightweight, stealthy, and built in Rust.
Unlike stateless sandboxes,
OpenComputer offers persistent VMs.
Your data survives across sessions, eliminating the need for constant re-installs. Enjoy a continuous workflow with the ability to scale resources instantly.
Firecracker consists of 83k lines of Rust, boots in 125ms, and powers AWS Lambda.
QEMU is a 1.4m-line C beast capable of emulating anything from a modern processor down to a Sound Blaster 16.
While most agent sandboxes opted for Firecracker, we chose QEMU. As agent capabilities become 100x more ambitious, simple function runtimes simply won't suffice.
We’re building the actual computers they need.

I am building a cloud - 2026-04-22
Today’s cloud is broken: rigid abstractions, overpriced networking, and bottlenecked SSDs. I’m building exe.dev to fix it.
A cloud designed for the era of AI agents where you control your resources, not the vendor.
Back to basics, back to computing.

Cube Sandbox is a high-performance, out-of-the-box secure sandbox service built on RustVMM and KVM.
creating a hardware-isolated sandbox environment with full service capabilities in under 60ms, while maintaining less than 5MB memory overhead.
Claude Mythos could root many shells, apparently.
Auto mode is a middle path that lets you run longer tasks with fewer interruptions while introducing less risk than skipping all permissions
Auto mode provides a safer long-running alternative to --dangerously-skip-permissions.
