DE:LIGHT The lightweight application server.
DE:LIGHT is the Decent Edge application server for small, message-driven workloads. Programs are written in Borz — a separate language project — and execute in one of two modes: DENSE (KVM-direct nanoservices, ~200 µs warm dispatch on the reference voting workload) or DEMIX (Firecracker microVM clusters). Every invocation produces a signed receipt. Run it on your own hardware, or use one of our managed services.
Same actor source. Two isolation models. Pick per workload.
KVM nanoservice mode
Borz actor compiles to a 2 KB flat binary that boots directly as a KVM guest. No Linux guest. Microsecond cold starts. Per-actor hardware isolation.
Microservice cluster mode
Borz actors on Firecracker microVMs with a thin Linux guest. Supervised handler lifecycle. gRPC fabric between actors. State replicates via Borz's distributed state framework (borz.ai).
DE:LIGHT runs Borz.
Borz is the actor-based language whose programs DE:LIGHT executes. It is a separate project under its own brand — borz.ai — and compiles to several targets including DENSE and DEMIX. Its distributed state framework is part of the same project. Decent Edge operates the server, not the language.

Every DE:LIGHT dispatch and every LLM call routed through the EU AI Gateway produces an Ed25519-signed receipt with payload hashes, host identity, and timestamps. EU AI Act Article 12 and GDPR Article 22 become a side-effect of normal operation. The full chain is documented on the attestation page.
