0.1
Find the real constraint.
Start with the system, the people operating it, and the failure that matters. A clear boundary is more useful than a broad promise.
Bordeaux / software systems
Built below the noise.
Quavern is a Bordeaux software studio building and running open-source AI, developer tools and public-data systems.
Four services are in operation. The latest release is QuavernOS Aurora 2026.0.
01 / Services
What we run.
Everything below is live and can be opened today.
- Marl The Quavern AI assistant, in the browser.
- Marl Code Agentic coding in the terminal, for macOS, Linux, Windows and NetBSD.
- QuavernOS A calm, NetBSD-based operating system for amd64 and arm64.
- Quavblok A multi-game Minecraft: Java Edition network.
- myQuavern One account for plans, consents and devices across every service.
02 / Method
Work the hard layer first.
Technology choices follow the constraint, not the fashion cycle.
0.2
Open the core.
Keep the important logic inspectable where openness creates reuse, confidence, and a credible route beyond one vendor.
0.3
Run the service.
Use hosted software where shared operation is the useful part: deployment, maintenance, collaboration, or live public data.
0.4
Leave a maintainable system.
Prefer legible interfaces, open formats, measured behaviour, and documentation that survives the first release.
03 / Practice
Four disciplines. One standard.
Every decision should be visible in the work, not only in the pitch.
| Practice | Quavern stance | Evidence to leave behind |
|---|---|---|
| AI | An implementation material, used when it improves the system. | Evaluations, failure cases, cost, and a non-magical fallback. |
| Open source | A way to make the durable core inspectable and reusable. | A licence, readable code, contribution paths, and releases. |
| SaaS | Shared operation where running the service creates value. | Clear boundaries, export paths, service status, and ownership. |
| Public data | Maps and transit treated as living systems, not decoration. | Sources, update dates, geometry, provenance, and accessibility. |
04 / Company
Run from Bordeaux.
“Open by default. Useful at street level. Maintained for the long run.”
