DEMIX · microservice cluster mode
Borz actors on Firecracker microVMs.
DEMIX is DE:LIGHT's medium-isolation execution mode — between a nanokernel and a full VM. Borz actors run on a thin Linux guest inside Firecracker microVMs. State replication uses Borz's distributed state framework (see borz.ai).
- Sandbox spawn P50
- 78 ms
- Source language
- Borz
What this mode gives you
- Sandbox spawn around 78 ms
- Supervised handler lifecycle
- gRPC fabric between actors; HTTP gateway out
- Signed receipt per spawn
- State replication via Borz's distributed state framework (borz.ai)

Where we focus
DEMIX is the medium-isolation tier in DE:LIGHT's spectrum, not a general-purpose sandbox platform. Borz actors get supervised lifecycle, gRPC fabric, and a signed receipt per spawn — useful when you want isolation, but the workload is small enough that a full Linux VM is overkill.
