Every package, one shelf.

The companion suite to uanetstandard-test-suite. Open62541-backed servers that cover the corners the .NET reference does not — full NodeManagement services and a second-implementation validation against the same scenarios. Non-overlapping ports (24840+), runs alongside the main suite.

OPC UA wired into Laravel with the idioms you already use — a service provider, the Opcua facade, config/opcua.php, log channels, cache stores, an Artisan command for the session-manager daemon. Switches transparently between the direct client and the daemon-backed managed client.

The terminal companion to opcua-client. Eleven commands — browse, read, write, watch, explore, trust, endpoints, code-generation and more — every one with --json output for pipelines. Ships as a Composer dep, a PHAR, or a static binary.

The foundation: a pure-PHP OPC UA client. Speaks the binary protocol over TCP, manages secure channels and sessions, ships the cryptography (10 security policies, RSA + experimental ECC) and emits 47 PSR-14 events at every lifecycle point. Synchronous, single-threaded, zero native dependencies beyond ext-openssl.

Pre-generated PHP classes for 51 OPC Foundation companion specifications — Robotics, Machinery, DI, AutoID, BACnet, MachineTool and more. 807 files: NodeId constants, typed enums, readonly DTOs, binary codecs, registrars. One ->loadGeneratedTypes() call and every read on a structured node returns a typed PHP object.

The client-side half of OPC UA Part 6 7.1.2.3: a listener that accepts the server-initiated ReverseHello (RHE) handshake instead of dialing out. Decodes the frame, gates the announced ServerUri against a fail-secure whitelist, then hands a fully connected Client back through the standard ClientBuilder - reusing the very socket the server opened. The way to reach edge gateways and PLCs behind NAT or a firewall.

The opc.https:// transport for opcua-client (OPC UA Part 6 7.4): every UA service message travels as a single HTTPS POST, with TLS as the secure channel so OpenSecureChannel is skipped. Ships a production-ready binary encoding (7.4.4) and a reference JSON encoding (7.4.5), behind a pluggable cURL HTTP client. Reaches OPC UA servers over 443, through the proxies and firewalls that block opc.tcp://.

The Subscriber half of OPC UA Part 14 - PubSub: a UDP listener (unicast or multicast) that decodes broadcast UADP and JSON NetworkMessages into typed DataSetMessages - group-key security, reader demux by (publisherId, writerGroupId, dataSetWriterId), PSR-14 events. Fire-and-forget telemetry from PLCs and field devices, no session or gateway in between, ext-sockets the only dependency beyond the core.

A long-running ReactPHP daemon that holds OPC UA sessions on behalf of short-lived PHP processes. Drop in ManagedClient for OpcUaClientInterface and your Laravel / Symfony / plain-PHP app reads, writes, and subscribes through a session that survives the request. Local IPC over Unix socket or TCP loopback.

A Symfony bundle for OPC UA. Autowireable OpcuaManager, YAML semantic configuration with a typed TreeBuilder, Monolog channels, PSR-16 cache pools, #[AsEventListener], and a bin/console opcua:session command. Targets Symfony 6.4 LTS, 7.x, and the upcoming 8.x.

A Docker-Compose suite of OPC UA test servers built on the OPC Foundation UA-.NETStandard reference implementation — 10 classic servers plus a Security Key Service and a PubSub publisher. Each server exposes the same ~300-node address space, differing only in security wrapping. Use it to integration-test any OPC UA client, in any language.
