Qorel¶
PLCs and SCADA were built to talk to a control-room screen a few metres away, not to a database, a cloud platform, or an AI agent.
Getting that data out reliably, continuously, and without losing any of it during the outages that are the normal condition at most real industrial sites, is a problem the software industry has been chipping away at for twenty years, mostly with tools designed before modern data streaming existed.
Qorel's bet is that this deserves the same technology the rest of the data industry already trusts for reliability at scale: not a bespoke buffer bolted onto legacy SCADA software, but a real, general-purpose streaming backbone, running at the very edge, on the gateway itself, so that no single point of failure, not the network, not the cloud, not a hard power cut, causes data loss.
Everything else here is either a consequence of that bet, or built on top of it.

Technical and market reference
The full picture: what it does, what runs today, and where it is headed. Start here if you are reading one document.

The operator interface, in screenshots.
-
How the gateway, control plane, adapters and sinks fit together.
-
Fifteen architecture decision records, with the reasoning and the alternatives that were rejected.
What runs today¶
Reusable adapter, sink and deployment objects. Protocol-aware configuration for Modbus TCP, Modbus RTU, MQTT and OPC UA. TimescaleDB, Kafka-compatible, HTTP and alert-routing sinks. A gateway runtime with local stream processing, validation, aggregation, health and overflow control. Gateway enrollment with Ed25519 device identity and operator approval. An always-on edge historian that backs operator history independently of any sink. Production Compose packaging for both the control plane and the edge gateway.
What does not¶
Qorel is not a finished product. The documents here are deliberately explicit about the difference between what ships and what is designed but unbuilt, and the decision records say so individually. The AI and MCP tooling layer described in ADR-010 is a recorded direction, not a shipped subsystem.
