Unified Automation OPC UA SDKs review
A multi-language OPC UA SDK family with a 90-day evaluation and sales-led licensing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Unified Automation OPC UA SDKs are a family of commercial development kits for teams adding OPC UA client, server or PubSub capabilities to their own products. The range covers C++, ANSI C, high-performance C, .NET, Java and Delphi development, with language and capability availability varying by SDK. It is aimed at developers who need libraries and helper functionality for OPC UA-enabled applications, including desktop and embedded targets. Windows and Linux are supported, alongside additional target environments for some offerings.
The breadth of the family is its main distinction: SDKs provide OPC UA services such as discovery, sessions, browsing, reading and subscriptions, and security handling supports OPC UA security profiles. PubSub offerings are available across multiple implementation languages. Samples, tutorials and reference documentation are included, and NuGet is listed for the .NET SDK. This makes the product family a fit for teams choosing a specific language and target environment, but buyers should match the requirements to an individual SDK rather than assume every option has the same features or platform coverage.
Licensing is commercial, with evaluation licenses available for 90 days; there is no perpetual free plan. The vendor directs prospective buyers to sales for license information, and licenses are issued per developer. These terms suit teams evaluating a defined implementation before purchasing, but make early budget planning dependent on a sales conversation. Choose Unified Automation when its language-specific SDK and supported targets fit the project; consider alternatives if you need transparent self-serve pricing or a free ongoing development tier.
