Show HN: Drop – a rootless Linux sandbox with gVisor support
↗
Drop provides a rootless Linux sandbox using gVisor for process isolation without requiring root privileges.
Engineers can isolate untrusted code safely within their existing Linux environment, preventing accidental or malicious access to host resources while maintaining workflow continuity.

Drop enables rootless sandboxing that isolates programs without leaving the user's familiar environment.
gVisor integration adds an extra isolation layer to prevent direct kernel access and reduce vulnerability exploitation risks.
Disposable environments with configurable TOML settings allow precise control over exposed files, directories, and network services.
THE READ
What the cluster adds up to.
The core innovation is rootless isolation using Linux user namespaces, eliminating the need for root access while providing process, mount, network, and cgroup namespace separation.
Adopting Drop requires no infrastructure changes, as it leverages the user's existing distribution and pre-installed packages without Docker/Podman setup.
The sandbox fails to protect against kernel-level exploits when gVisor is not used, and its security depends entirely on the host system's namespace implementation.
Unlike container-based solutions, Drop's approach avoids container runtime overhead but lacks the ecosystem maturity of established isolation tools.
The TOML configuration model offers flexible exposure control but introduces a learning curve for users accustomed to traditional sandboxing workflows.
