Sveltia CMS is a Git-based lightweight headless CMS under active development as a modern, powerful, quick replacement for Netlify CMS and Decap CMS. In some simple cases, migration is as easy as a single line of code change, although we are still working on improving compatibility.
The free, open source alternative to Netlify/Decap CMS is now in public beta, turbocharged with great UX, performance, i18n support and so many more enhancements.
Sveltia CMS was born in November 2022, when the progress of Netlify CMS was stalled for more than six months. @kyoshino’s clients wanted to replace their Netlify CMS instances without much effort, mainly to get better internationalization (i18n) support.
To achieve radical improvements in UX, performance, i18n and other areas, it was decided to build an alternative from the ground up, while ensuring an easy migration path from the other. After proving the concept with a rapid Svelte prototype, development was accelerated to address their primary use cases. The new product has since been named Sveltia CMS and released as open source software to encourage wider adoption.
Due to its unfortunate abandonment, Netlify CMS spawned 3 successors:
Sveltia CMS is the only project that doesn’t inherit the complexity, technical debt and numerous bugs of Netlify CMS, which was launched back in 2015. We are confident that our decision to rebuild the application from scratch was the right one, as proven by the hundreds of improvements we have already made.
While Sveltia CMS is specifically designed to replace legacy Netlify CMS instances, it also aims to serve as a substitute for the other Netlify CMS successors. We hope that, especially with the robust i18n support, our product will eventually become an attractive choice for anyone looking for a free headless CMS.
Sveltia CMS is currently in beta and version 1.0 is expected to ship in early 2025, in time for the 10th anniversary of Netlify CMS development. Check our release notes for updates. See also our roadmap.
While we fix reported bugs as quickly as possible, usually within 24 hours, our overall progress may be slower than you think. The thing is, it’s not just a personal project of @kyoshino, but also involves different kinds of activities that require considerable effort:
We are working hard to create a tremendously better alternative to Netlify CMS and Decap CMS by improving everything. Here’s what makes Sveltia CMS different. Look how serious we are!

[^95][^27].Sveltia CMS has been built with a multilingual architecture from the very beginning. You can expect best-in-class internationalization (i18n) support, as it’s required by clients of maintainer @kyoshino, who himself was a long-time Japanese localizer for Mozilla and currently lives in a multicultural city where 150+ languages are spoken.

It’s ready to be used as a drop-in replacement for Netlify/Decap CMS in some casual use case scenarios with a single line of code update.
However, 100% feature parity is not planned, and some features are still missing or will not be added due to performance, deprecation and other factors. Look at the compatibility info below to see if you can migrate now or in the near future.
window.CMS
object will not be implemented. This includes custom backends and custom media libraries, if any; we may support these features in the future, but our implementation would likely be incompatible with Netlify/Decap CMS.These limitations are expected to be resolved before or shortly after GA:
Feature | Status in Sveltia CMS |
---|---|
Backends | The Test backend needed for our demo site is not yet added. We’ll see if Azure DevOps can also be supported. |
Configuration | Comprehensive config validation is not yet implemented. |
Localization | The application UI is only available in English and Japanese at this time. |
Media Libraries | Cloudinary and Uploadcare are not yet supported. |
Workflow | Editorial Workflow and Open Authoring are not yet supported and will be implemented after the 1.0 release. |
Collections | Nested collections (beta) are not yet supported and will be implemented after the 1.0 release. |
Widgets | Custom widgets are not yet supported. See the table below for other limitations. |
Customizations | Custom previews and event subscriptions are not yet supported. |
Widget | Status in Sveltia CMS |
---|---|
Code | Not yet supported. |
DateTime | The date_format and time_format options with Moment.js tokens are not yet supported. Note that Decap CMS 3.1.1 replaced Moment.js with Day.js, and Decap CMS 3.3.0 made other changes to the widget behaviour; we’ll follow these changes where it makes sense. |
File / Image | Field-specific media folders (beta) and media library options are not yet supported other than media_library.config.max_file_size for the default media library. |
Map | Not yet supported. |
Markdown | The built-in code-block component and custom components are not yet supported. |
localhost
or 127.0.0.1
URLs. If you’re running a remote server yourself and it’s served over HTTP, get a TLS certificate from Let’s Encrypt.Currently, Sveltia CMS is primarily intended for existing Netlify/Decap CMS users. If you don’t have it yet, follow their documentation to add it to your site and create a configuration file first. Make sure you choose the GitHub or GitLab backend (and ignore the Choosing a Backend page). Then migrate to Sveltia CMS as described below.
As the product evolves, we’ll implement a built-in configuration editor and provide comprehensive documentation to make it easier for everyone to get started with Sveltia CMS.
Here are some starter kits for popular frameworks created by community members. More to follow!
Alternatively, you can probably use one of the Netlify/Decap CMS templates and make a quick migration to Sveltia CMS.
Have a look at the compatibility info above first. If you’re already using Netlify/Decap CMS with the GitHub or GitLab backend and don’t have any unsupported features like custom widgets or nested collections, migrating to Sveltia CMS is super easy — it works as a drop-in replacement. Edit /admin/index.html
to replace the CMS <script>
tag, and push the change to your repository. Your new <script>
tag is:
<script src="https://unpkg.com/@sveltia/cms/dist/sveltia-cms.js"></script>
From Netlify CMS:
-<script src="https://unpkg.com/netlify-cms@^2.0.0/dist/netlify-cms.js"></script>
+<script src="https://unpkg.com/@sveltia/cms/dist/sveltia-cms.js"></script>
From Decap CMS:
-<script src="https://unpkg.com/decap-cms@^3.0.0/dist/decap-cms.js"></script>
+<script src="https://unpkg.com/@sveltia/cms/dist/sveltia-cms.js"></script>
That’s it! You can open https://[hostname]/admin/
as before to start editing. There is even no authentication process if you’ve already been signed in with GitHub or GitLab on Netlify/Decap CMS because Sveltia CMS uses your auth token stored in the browser. Simple enough!
That said, we strongly recommend testing your new Sveltia CMS instance first on your local machine. See below for how.
Sveltia CMS does not support the Git Gateway backend due to performance limitations. If you don’t care about user management with Netlify Identity, you can use the GitHub or GitLab backend instead. Make sure you install an OAuth client on GitHub or GitLab in addition to updating your configuration file. As noted in the document, Netlify is still able to facilitate the auth flow.
To allow multiple users to edit content, simply invite people to your GitHub repository with the write role assigned.
Once you have migrated from the Git Gateway and Netlify Identity combo, you can remove the Netlify Identity widget script tag from your HTML:
-<script src="https://identity.netlify.com/v1/netlify-identity-widget.js"></script>
If you want to stay with Netlify Identity, unfortunately you can’t migrate to Sveltia CMS right now. We plan to develop a high-performance Git Gateway alternative with Netlify Identity support in the future.
For advanced users, we have also made the bundle available as an npm package. You can install it by running npm i @sveltia/cms
or pnpm add @sveltia/cms
on your project. The manual initialization flow with the init
method is the same as for Netlify/Decap CMS.
Updating Sveltia CMS is transparent, unless you include a specific version in the <script>
source URL or use the npm package. Whenever you (re)load the CMS, the latest version will be served via UNPKG. The CMS also periodically checks for updates and notifies you when a new version is available. After the product reaches GA, you could use a semantic version range (^1.0.0
) like Netlify/Decap CMS.
If you’ve chosen to install with npm, updating the package is your responsibility. We recommend using ncu
or a service like Dependabot to keep dependencies up to date, otherwise you’ll miss important bug fixes and new features.
You can host your Sveltia CMS-managed site anywhere, such as Cloudflare Pages or GitHub Pages. But moving away from Netlify means you can no longer sign in with GitHub or GitLab via Netlify. Instead, you can use our own OAuth client, which can be easily deployed to Cloudflare Workers, or any other 3rd party client made for Netlify/Decap CMS.
Sveltia CMS supports a configuration file written in the JSON format in addition to the standard YAML format. This allows developers to programmatically generate the CMS configuration to enable bulk or complex collections. To do this, simply add a <link>
tag to your HTML, just like a custom YAML config link, but with the type application/json
:
<link href="path/to/config.json" type="application/json" rel="cms-config-url" />
Alternatively, you can manually initialize the CMS with a JavaScript configuration object.
If you get an “Authentication Aborted” error when trying to sign in to GitHub or GitLab using the authorization code flow, you may need to check your site’s Cross-Origin-Opener-Policy
. The COOP header is not widely used, but it’s known to break the OAuth flow with a popup window. If that’s your case, changing same-origin
to same-origin-allow-popups
solves the problem. (Discussion)
Sveltia CMS has simplified the local repository workflow by removing the need for additional configuration (the local_backend
property) and a proxy server (netlify-cms-proxy-server
or decap-server
), thanks to the File System Access API available in some modern browsers.
Basically there are only two differences from Netlify/Decap CMS: you don’t need to run the proxy server, and you need to select your project folder in the browser instead. Here are the detailed steps:
name: git-gateway
won’t work. You’ll need either name: github
or name: gitlab
along with the repo
definition. If you haven’t determined your repository name yet, just use a tentative name.npm run dev
or pnpm dev
.http://localhost:[port]/admin/index.html
with Chrome or Edge.127.0.0.1
addresses can also be used instead of localhost
./admin/
, use the appropriate path.git init
) or GUI, and the hidden .git
folder exists.git diff
or a GUI like GitHub Desktop.http://localhost:[port]/
to check the rendered pages.Keep in mind that, as with Netlify/Decap CMS, the local repository support in Sveltia CMS doesn’t perform any Git operations. You’ll have to manually fetch, pull, commit and push all changes using a Git client. In the future, we’ll figure out if there’s a way to do this in a browser, because netlify-cms-proxy-server
actually has the undocumented, experimental git
mode that allows developers to create commits to a local repository[^131].
Also, at this point, you have to reload the CMS to see the latest content after retrieving remote updates. This manual work will hopefully be unnecessary once the proposed FileSystemObserver
API, which is being implemented in Chromium behind a flag, becomes available.
If you have migrated from Netlify/Decap CMS and are happy with the local repository workflow of Sveltia CMS, you can remove the local_backend
property from your configuration and uninstall the proxy server. If you have configured a custom port number with the .env
file, you can remove it as well.
In the Brave browser, you must enable the File System Access API with an experiment flag to take advantage of local development.
brave://flags/#file-system-access-api
in a new browser tab.You can specify an icon for each collection for easy identification in the collection list. You don’t need to install a custom icon set because the Material Symbols font file is already loaded for the application UI. Just pick one of the 2,500+ icons:
config.yml
as the new icon
property, like the example below. - name: tags
label: Tags
+ icon: sell
create: true
folder: data/tags/
Sveltia CMS allows developers to add dividers to the collection list to distinguish different types of collections. To do this, insert a fake collection with the divider: true
option along with a random, unique name
. In VS Code, you may get a validation error if config.yml
is treated as a “Netlify YAML config” file. You can work around this by adding an empty files
list as well:
collections:
- name: products
...
- divider: true
name: d1 # d2, d3, etc. Should be unique for each divider
files: []
- name: pages
...
This is actually not new in Sveltia CMS but rather an undocumented feature in Netlify/Decap CMS[^4]. You can specify media and public folders for each collection that override the global media folder. Well, it’s documented, but that’s probably not what you want.
Rather, if you’d like to add all the media files for a collection in one single folder, specify both media_folder
and public_folder
instead of leaving them empty. The trick is to use an absolute path for media_folder
like the example below. You can try this with Netlify/Decap CMS first if you prefer.
media_folder: static/media
public_folder: /media
collections:
- name: products
label: Products
create: true
folder: data/products/
+ media_folder: /static/media/products # start with a slash
+ public_folder: /media/products
In Sveltia CMS, those collection media folders are displayed prominently for easier asset management. We recommend setting media_folder
and public_folder
for each collection if it contains one or more File/Image fields.

Sveltia CMS comes with a handy DeepL integration so that you can translate any text field from another locale without leaving the Content Editor. To enable the high quality, AI-powered, quick translation feature:
Note that the Translation button on the pane header only translates empty fields, while in-field Translation buttons override any filled text.
If you have upgraded to DeepL API Pro, provide your new Authentication Key:
In Sveltia CMS, it’s possible to localize entry slugs (filenames) if the i18n structure is multiple_files
or multiple_folders
. All you need is the localize
filter for slug
template tags:
i18n:
structure: multiple_folders
locales: [en, fr]
slug:
encoding: ascii
clean_accents: true
collections:
- name: posts
label: Blog posts
create: true
folder: data/posts/
slug: '{{title | localize}}' # This does the trick
format: yaml
i18n: true
fields:
- name: title
label: Title
widget: string
i18n: true
With this configuration, an entry is saved with localized filenames, while the default locale’s slug is stored in each file as an extra translationKey
property, which is used in Hugo’s multilingual support. Sveltia CMS and Hugo read this property to link localized files.
data/posts/en/my-trip-to-new-york.yaml
translationKey: my-trip-to-new-york
title: My trip to New York
data/posts/fr/mon-voyage-a-new-york.yaml
translationKey: my-trip-to-new-york
title: Mon voyage à New York
You can customize the property name and value for a different framework or i18n library by adding the canonical_slug
option to your top-level or collection-level i18n
configuration. The example below is for @astrolicious/i18n, which requires a locale prefix in the value (discussion):
i18n:
canonical_slug:
key: defaultLocaleVersion # default: translationKey
value: 'en/{{slug}}' # default: {{slug}}
For Jekyll, you may want to use the ref
property:
i18n:
canonical_slug:
key: ref
You can disable output of content in selected non-default locales by adding the save_all_locales
property to the top-level or collection-level i18n
configuration. Then you’ll find “Disable (locale name)” in the three-dot menu in the top right corner of the Content Editor. This is useful if the translation isn’t ready yet, but you want to publish the default locale content first.
With the following configuration, you can disable the French and/or German translation while writing in English.
i18n:
structure: multiple_files
locales: [en, fr, de]
default_locale: en
+ save_all_locales: false
By default, the slug for a new entry file will be generated based on the entry’s title
field. Or, you can specify the collection’s slug
option to use the file creation date or other fields. While the behaviour is generally acceptable and SEO-friendly, it’s not useful if the title might change later or if it contains non-Latin characters like Chinese. In Sveltia CMS, you can easily generate a random UUID for a slug without a custom widget!
It’s simple — just specify {{uuid}}
(full UUID v4), {{uuid_short}}
(last 12 characters only) or {{uuid_shorter}}
(first 8 characters only) in the slug
option. The results would look like 4fc0917c-8aea-4ad5-a476-392bdcf3b642
, 392bdcf3b642
and 4fc0917c
, respectively.
- name: members
label: Members
create: true
folder: data/members/
+ slug: '{{uuid_short}}'
Sveltia CMS allows you to edit and save a list at the top-level of a data file, without a field name. All you need to do is create a single List field with the new root
option set to true
. The configuration below reproduces this Jekyll data file example:
collections:
- name: data
label: Data Files
files:
- name: members
label: Member List
file: _data/members.yml
fields:
- name: members
label: Members
label_singular: Member
widget: list
root: true # This does the trick
fields:
- name: name
label: Name
- name: github
label: GitHub account
Note: The root
option is ignored if the collection or collection file contains multiple fields. You can still have subfields under the List field.
You may already have a CI/CD tool set up on your Git repository to automatically deploy changes to production. Occasionally, you make a lot of changes to your content to quickly reach the CI/CD provider’s (free) build limits, or you just don’t want to see builds triggered for every single small change.
With Sveltia CMS, you can disable automatic deployments by default and manually trigger deployments at your convenience. This is done by adding the [skip ci]
prefix to commit messages, the convention supported by GitHub Actions, GitLab CI/CD, CircleCI, Travis CI, Netlify, Cloudflare Pages and others. Here are the steps to use it:
automatic_deployments
property to your backend
configuration with a value of false
: backend:
name: github
repo: owner/repo
branch: main
+ automatic_deployments: false
[skip ci]
is automatically added to each commit message. However, deletions are always committed without the prefix to avoid unexpected data retention on your site.[skip ci]
.If you set automatic_deployments
to true
, the behaviour is reversed. CI/CD will be triggered by default, while you have an option to Save without Publishing that adds [skip ci]
only to the associated commit.
Gotcha: Unpublished entries and assets are not drafts. Once committed to your repository, those changes can be deployed any time another commit is pushed without [skip ci]
, or when a manual deployment is triggered.
If the automatic_deployments
property is defined, you can manually trigger a deployment by clicking the Publish Changes button on the application header. To use this feature:
repository_dispatch
event with the sveltia-cms-publish
event type. Update your build workflow to receive this event: on:
push:
branches: [$default-branch]
+ repository_dispatch:
+ types: [sveltia-cms-publish]
If your site adopts Content Security Policy (CSP), use the following policy for Sveltia CMS, or some features may not work.
style-src 'self' 'unsafe-inline' https://fonts.googleapis.com;

(UNPKG is used not only to download the CMS script bundle, but also to check for the latest version and retrieve additional dependencies such as PDF.js)
Then, add the following origins depending on your Git backend and enabled integrations.
