✨ What's new in FireCMS 3.0

The new version of FireCMS is a major release that brings a lot of new features and improvements. This page will guide you through the most important changes 🔥

FireCMS Cloud makes now use of a backend to provide a more flexible and customizable experience.

Until now, FireCMS was a frontend-only library that would connect directly to the client-side Firebase SDK. This was great for simple use cases, but it limited the flexibility of the library. For example, it was not possible to customize collections from the UI, since they were hard coded in the clients code.

Having a backend allows us to store configuration in Firestore, and to make it easy for end users to modify the schemas. We have done a lot of work to prevent polluting your database with FireCMS' configuration.

Having a backend also allows us to provide a better experience by offering additional features such as data enhancement through OpenAPI GPT-4.

Docs have been revamped and are now better in every way. Many documents have been adapted to the new version of FireCMS, and we have added new ones.

New UI collection schema editor

Until now, the collection schema was defined in the client-side code. This was great for simple use cases, but it limited the flexibility of the library. For example, it was not possible to customize collections from the UI, since they were hard coded in the clients code.

In FireCMS Cloud, the collection schema is stored in FireCMS backend, but you are also able to define your collections in code for greater flexibility. Your end users will be able to modify the collection schema. Let's say you have a collection of Posts and you want to add a new possible value for the enum status. You can now open the collection editor and add the new value. Even better, FireCMS can find new values and add them to your schema with one click!

You can still limit the properties that can be modified from the UI, and you can also define the default values for new documents.

New data inference

Do you have a few collections in your project, and you want to get started quickly? FireCMS can now infer the schema from your data. This means that you can get started with FireCMS in a few minutes, without having to write a single line of code.

In previous versions of FireCMS, you could add your external search engine solution like Algolia or ElasticSearch. This is still possible, but now you can also search your data locally. This means that you can search your data without having to pay for an external service. This is great for small projects, or when you are just getting started.

This feature is meant to be used with small datasets. If you have a large dataset, you should still use an external search engine.

Data import and export


You now have better control of how your data is exported:

  • Define the format of your dates
  • Define how arrays get serialized in CSV files (assign one column per array item, or serialize the array as a string)
  • Export your data as JSON or CSV.


You can now import data from CSV, JSON or Excel files. This is great for migrating data from other systems. We incorporate a modern UI that allows to define how the data is imported and how it is mapped to your collections.

Tailwind migration and performance improvements

Versions 1.0 and 2.0 of FireCMS were based on Material UI (mui). This was great for getting started quickly, but it had some drawbacks. The main one was that performance was not great. The styling solution of MUI is based on emotion which resolves styles at runtime. This means that the browser has to do a lot of work to resolve the styles. This is not a problem for small applications, but it can be a problem for large applications.

In FireCMS 3.0 we have migrated to Tailwind CSS. This is a utility-first CSS framework that allows us to generate a small CSS file with all the styles resolved at build time. This means that the browser does not have to do any work to resolve the styles, which results in a much faster experience. 🚀

New authentication system

We now provide a new authentication system that allows managing CMS users and roles from the UI.

If you prefer defining permissions for each collection in code, you can still do it.

New component library and Icons

We have also created a new component library that you can use to build your own components (or use it in any project you like really!). You can get it from npm:

yarn add @firecms/ui

(you only need to install it if you want to use it in a different project)

The components are fully typed and documented. You can find the documentation here. They are based in Tailwind CSS and Radix UI. They are easily customizable, and you can use them to build your own components. They are also accessible and responsive.

Icons collection

You can customise the icons in different parts of the CMS, such when selecting one for a collection. FireCMS UI now exports all the Material Icons, conveniently exported as React components.

We have also added an icon search function in the website to find the icon you need.

It makes it easy to find the right icon key when defining configuration for your collections, or to find the right icon component when you want to use it in your own components.


Use the CLI to deploy your custom code with a single command:
