From the creators of node-opcua
node-opcua in production — assured, secured, accountable.
Running node-opcua in a real product or plant? Get a direct line to the engineers who wrote it — priority fixes, security and CRA readiness, and an SLA, through your own private space on our GitLab.
Direct access to the people who maintain the stack
A support membership is not a helpdesk ticket queue. It's a working relationship with the engineers who write node-opcua — delivered through the same tools they use every day.Private GitLab space
Day-to-day work, directly with the maintainers
Your team gets a dedicated, confidential project on our GitLab instance. File issues, share code, discuss architecture — all in a space only you and the Sterfive engineering team can see. No support portal, no middlemen.
Priority fixes upstream
Fixes that land in node-opcua itself
When you hit a bug, we don't just patch around it — we fix it in the upstream codebase and ship a release. Only the maintainer can promise this. Your fix benefits the entire ecosystem, and you get it first.
Security & CRA readiness
CVE response, NIS2 and IEC 62443 evidence
Get proactive security advisories, coordinated CVE disclosure, and the compliance evidence your auditors need. As the Cyber Resilience Act (CRA) reshapes open-source liability, a documented relationship with the maintainer is the strongest proof you can have.
Certified builds & SLA
Maintained versions and an upgrade path
Receive tested, signed builds of node-opcua with guaranteed response times. We maintain an upgrade path so you're never stuck on an unsupported version — and your procurement team gets the contract they need.
We are the maintainer of node-opcua.
Not a reseller. Not a wrapper. The engineering team that writes, reviews, and ships every release.
"When you take node-opcua into production, you're building on ten years of protocol engineering and thousands of interoperability tests. A support membership gives you a direct line to that expertise — and the accountability that comes with it. We don't escalate your issue to someone else; we fix it in the codebase we own."
Etienne Rossignon — Creator of node-opcua & CEO of Sterfive
