You can still resume using them if you click the ‘Load extension’ button on each extension, or the ‘Load all extensions’ banner at the top of the Extensions dashboard. **Can I create a custom extension?** You can use [React](https://reactjs.org/) to create your own real-time, interactive extensions that live in Airtable. We host your code, so you don't have to worry about servers or setup. You can create your extension in your own development environment and import your favorite npm packages. The full API Reference and tutorial guides for the Blocks SDK can be found on [our developers site](https://www.airtable.com/developers/blocks). **How can I manage all of the extensions on a base?** We cover the ins and outs of managing extensions on a base in [this support article](/docs/managing-and-organizing-extensions-on-a-base#managing-all-base-extensions). **What happens to my extensions when I downgrade?** If you downgrade to the Free plan, then existing installations of extensions in your bases will be disabled. This means that you will be unable to view or interact with these extensions. If, in the future, you decide to re-upgrade your workspace plan to a paid plan, the disabled extensions in your bases will be reenabled with the same settings that they had at the time when you downgraded **How can I install an unlisted extension?** Remember that these kinds of extensions have not been reviewed by Airtable. Make sure you only add unlisted extensions from developers you trust. If you are still having issues, click ![](https://cdn.airtable.document360.io/d0ee2ee4-3f78-47c7-b388-85e40be9fb89/Images/Documentation/Screenshot 2026-02-11 at 5.09.50 PM(1).png) on the lower right corner to contact Airtable Support. **How do I publish a script to the Extensions Marketplace?** Our [Extensions marketplace](https://airtable.com/marketplace) includes scripts written by Airtable customers. With the introduction of **script templates**, any user - even without technical knowledge - will be able to leverage the power of the Scripting Extension by installing pre-built scripts created by Airtable *and* members of Airtable’s growing community. For full details about developing an extension and our review process, [please visit our developer documentation](https://airtable.com/developers/scripting/examples/publishscript). **Were extensions ever known by another name?** Yes, two names in fact. Extensions were first named “Blocks” and then “Apps.” We changed the names to better align with the functionality of this product feature.
