In production

Private, self-hosted S3-compatible object storage

Lockwell is S3-compatible object storage that runs as one container with one volume. Encryption at rest is always on, every tenant has its own keys, and there are no public buckets.

Developer tools

Sentinel

In development

A self-hosted CI engine in Rust

Sentinel runs your pull request checks on your own machines, in rootless containers, and reports them back as native GitHub checks. It is in early development; sub-minute warm checks are a goal, not a measured result.

Business software

Desktop apps
