Self-hosted infrastructure and apps
Self-hosted object storage, a self-hosted CI engine, business software and desktop apps, built in Portugal.
Lockwell
In productionLockwell 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.
Sentinel
In developmentSentinel 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.
TangibleShift
In developmentA Portugal-first SaaS ERP for small and medium businesses, their accountants and owner-operators, with IVA, invoicing and SAF-T (PT) handled correctly from the start.
Small, focused software for Windows and the desktop, and open-source projects we look after.

Company
Lockwell object storage, the Sentinel CI engine, the TangibleShift ERP, the Komorebi email client, two game tools and a Pico CSS fork: what each is for.
What the products share
Storage, CI, business software and desktop apps built in Portugal, each one clear about what it does today and what is still a goal.
Lockwell and Sentinel run on hardware you control. Lockwell is one container and one volume, with no external database, broker or cache.
When we publish a number, we say where it was measured, like Komorebi's beta notes. Targets, like Sentinel's sub-minute PR checks, are labelled as goals.
Komorebi and Vaulter are GPL-3.0, and Sentinel, Scribe and Pico Reforged are MIT licensed. An MIT-licensed source release of Lockwell is planned.
