01Why we built this
We managed NixOS fleets for years before we built NixFleet. The four crises listed on the home page are not academic. They were the daily texture of operations: configuration drift on infrastructure we could not prove was identical, sovereignty exposure on cloud control planes we did not control, security bolted on by detection tools we could not reason about, and compliance produced as PDFs by humans rather than as signed evidence by the system.
NixFleet is the framework we wanted: the signed-artifact chain end-to-end, magic rollback as a protocol property, compliance as a release gate. The point is not novelty. The point is that each of these properties already exists in the Nix model. We assembled them.
02Why now
NIS2 transposition deadlines have passed. DORA is applicable to financial entities since January 2025. ANSSI BP-028 v2.0 is the reference for French infrastructure hardening. Operators under these regimes need declarative tooling that produces signed evidence as a side effect of normal operation, not a separate compliance project layered on top of an imperative stack.
03What this is not
- Not a startup story. No funding round, no valuation, no IPO trajectory. The open core funds itself through Pro and Enterprise tiers. The surplus funds open-source work.
- Not AI-anything. NixFleet is a systems framework. The trust model relies on cryptographic primitives, not on probabilistic inference.
- Not VC-backed. Independent, EU-based, sovereignty-first by design and by economics.
- Not pretending to be 50 people. Founder plus ecosystem. The framework benefits from the broader NixOS community. Commercial work is delivered by a small core.
