Freedom only

At Yenlo we are happy fan of WSO2. We breathe open source. No licenses, no obligations, but FREEDOM and endless innovation. It’s in our motto: What you need is what you get. We use the open source integration platform to build the future of your business technology. You get complete middleware, not just a hub that deals with messages. And you get us, your main partner. Worldwide. No. 1. No kidding. Check.


WUM is a simple command line tool that connects to WSO2 Update, determines which updates are new and relevant, and downloads them. You can run WUM once to update the software to the latest set of released updates, or schedule it to run periodically so you maintain the latest set of updates continuously.

Note that WUM will not itself automatically push into production – you have full control over when and how you want such pushes to occur.

The WSO2 Update Manager is part of the 100% open source integration platform WSO2 where you also can find products like the WSO2 Identity Server (WSO2 IS), WSO2 Enterprise Service Bus (WSO2 ESB), WSO2 API Manager (WSO2 API), WSO2 Data Analytics Server (WSO2 DAS) and the world famous WSO2 Carbon framework.

Updates published through WSO2 Update are NOT open source – they are released under the WSO2 Update License. In short, this means that updates can be freely used in NON-PRODUCTION deployments such as development environments and test environments. Updates can be used in PRODUCTION only under a paid WSO2 Subscription.

If you want to continue to use the 100% open source products, please download the latest version. All updates will be added to future releases. 

WSO2 Update services are available for the following products and versions. Check back regularly as we add more products and versions to this list:

Q: Can I use updates without a paid subscription?

A: Yes, in non-production environments. Updates are licensed for anyone to use freely for development, test, and staging. We want everyone evaluating, developing on, or preparing WSO2 products for production deployments to have the best experience – and especially not trip over a bug that has already been fixed! However you cannot push the updates into a production environment without a paid subscription for that product. You will have to wait for one of our periodic dot releases that roll up all recent updates into an open source release that can be used in production for free.

Q: What additional benefits will I get from a paid subscription?

A: A paid subscription allows you to deploy updates into production, so fixes are available immediately instead of waiting for a future release. A subscription also includes our renowned 24x7 support services to reduce risk, resolve issues more quickly, and (if one doesn’t already exist) develop a new update to resolve an issue you are experiencing. Our customers believe the subscription provides excellent value for money. Subscriptions fund our ongoing R&D and operations – our customers form a community supporting the ongoing evolution of the platform.

Q: Do I need a key to unlock updates for production use

A: No. License keys are a hassle our customers are eager to avoid. We believe we can trust our users to adhere to the license terms. We make the terms amply clear to avoid accidental violations, and reserve the right to remove access to updates or take other means to enforce the license against intentional violators.

Q: Can I pick and choose which updates to install?

A: We are not supporting picking and choosing of updates. To maximize reliability each update is tested and certified on systems in which all previous updates have been installed. Allowing an arbitrary set of updates could result in an unsustainable combinatorial explosion of versions that is not practical to support. However, you always can choose when to push a (coherent) set of updates into production.

Q: Is WSO2 Update Manager open source?

A: No. WSO2 Update Manager and the WSO2 Update service are tightly coupled, and we are releasing WSO2 Update Manager with a commercial EULA instead of as open source.
