GitHub Sponsors Profile

Keep the OPC UA stack your factory depends on alive and current.
If your team ships products that talk OPC UA from Node.js, there's a good chance you're running node-opcua in production. Mercedes-Benz does. So do automotive Tier-1s, energy operators, and IoT platforms across Europe, North America, and Asia.
node-opcua is maintained primarily by one person at Sterfive in France. Every Node.js LTS upgrade, every OPC UA spec revision, every CVE patch comes from that work. Sustaining sponsors are what let us keep that engineering time pointed at the open project instead of being fully absorbed by paid contracts.

🌟 Founding Sponsors — open until end of Q1 2026
The first 5 organizations to sponsor node-opcua at Bronze tier ($250/month) or above are recognized as Founding Sponsors of the program. This status is permanent and will not be available to any sponsor joining after Q1 2026 — at any tier, including Platinum.
Founding Sponsors receive, in addition to their tier benefits:

🏛️ "Founding Sponsor" designation on node-opcua.github.io and the GitHub README, distinct from regular sponsor recognition
📜 Permanent listing in the project's Founding Sponsors honor roll, including after the program closes
🗣️ Direct input on the 2026 roadmap and unlock priorities
🤝 A standing annual call with the maintainer (independent of tier-level benefits)

This program exists because a small number of industrial users have quietly depended on node-opcua for years. Founding Sponsor status is how the project formally acknowledges that history — and gives those organizations a permanent seat at the table as node-opcua scales.

What your sponsorship funds — concretely
Sponsorship in 2026 directly funds:

OPC UA 1.05 continued migration (Q2–Q3 2026)
Security patch SLA for the open repo — currently best-effort, sponsors make it predictable
OPC Foundation participation — representing the Node.js community in spec discussions
Node.js 24 LTS compatibility and ongoing runtime upgrades
