Introduction
The new Agility UI showcases the Plenum design system that it is based on. This design system provides the foundation for the UI, as well as the Apps, both in the marketplace and any private apps you may create for your organization.
The Agility Content Manager is built on the Plenum design system. This design system provides the foundation for the UI, as well as the Apps, both in the marketplace and any private apps you may create for your organization.

As a concept, Plenum is an enterprise design system that outlines how we approach User Experience in Agility. In practice, it's a set of components and larger elements that use that system to create the Content Manager app itself. You can actually browse the available components here - we've open-sourced the library as a set of Storybook.js components. This is part of our larger strategy that allows developers to create Apps that extend the Content Manager App into new areas and integrations. These Apps can share the same design principles as Plenum by using the components we've made available.
The current UI launched as Beta 1 in October 2022 with the editor-centric sections first: the Home dashboard, Content, Pages and Assets.
The other sections followed: Models in November 2022, Settings in February 2023, and the Org section (Instance, Users, Teams, Billing and Apps) in May 2023. Reports are also part of the current UI.
In July 2023 the new UI became the default for new customers and trial users. Existing customers could switch to it and set it as their default from their profile options, and could switch back to the classic UI when they needed to.

This update is based primarily on user feedback from customers and partners. We've listened, and we've learned how people want Agility to work, and how they want it look while they're using it.
We've kept many of the same paradigms that our customers told us they liked while moving away from things that aren't as useful or intuitive.
The app has a header navigation across the top and a side rail panel. Both were redesigned in August 2026 for a cleaner, more organized experience. As you navigate deeper into linked items, you'll notice a breadcrumb along the top that allows you to get back to the original items and also indicates clearly what item you're currently on.
Other parts of the UI were refreshed in 2026 as well. All 98 modals were redesigned to match the updated design system (May 2026), slide-out panels were converted to modals over the following months, and the side panels for models, pages, content lists and content items were refreshed to match the new navigation (September 2026).
We've also made it much easier to control the sizing and spacing with the ability to resize the left panel, manually collapse and expand the new right panel, and resize columns in grids.
This video, recorded during the 2022 beta, shows panel resizing in the earlier layout:
As we stated above, Apps are the future of no-code integrations with Agility. We want you to be able to easily extend the UI and to connect with the business tools you need.
As such, all apps built using the latest SDK will function the same as the new UI, including all 1st-party apps such as the Cloudinary, Block Editor, Formstack apps and more (with more coming soon!).
We have decided not to support legacy custom fields or legacy input forms in the new interface. You will be able to continue to use the classic UI for those. We will be announcing a strategy for all legacy elements and integrations at a later date.
When Beta 1 launched, these features were only available in the classic UI. They are all part of the current UI now:
One of the really cool things that we've brought to the new UI is the ability to refresh or reload your browser window while editing content without losing your changes. We now save your content item edits locally while you're working so that if you navigate away, you can return to that item and continue editing. Furthermore, if someone else edits the item that you're working on, you'll get a notification about that, allowing you to then "revert" your changes or save your version of the item.

We're continuing to innovate and to bring more features, both in new and existing, into the new Agility UI.
We hope you'll love it!
