Adobe Muse Is Discontinued. Here's the Open Source Alternative

If you built websites in Adobe Muse, you already know the feeling. You opened a tool made for designers, laid out a real site the way you saw it in your head, and shipped actual HTML without writing a line of code. Then Adobe walked away from it. Feature development stopped in 2018, and all support and security updates ended on March 26, 2020.

Muse still launches for some people. That is exactly the problem. It runs, but it gets no fixes, no security patches, and no compatibility work as operating systems and browsers move on. Every month it drifts further from the modern web, and one OS update can end the story for good. If you are reading this, you are probably looking for somewhere honest to land.

Of all the discontinued visual builders, Muse designers are the audience free software fits best. Here is why, and what your options actually are.

Muse still opens, but that is not a plan

The tempting move is to keep using Muse until it finally breaks. Plenty of designers are doing that right now. It works until it doesn't: an incompatible macOS or Windows release, a security flaw that will never be patched, or a client site that quietly stops rendering correctly on new browsers.

There is no official Adobe successor. Adobe never replaced Muse with an equivalent visual, code-free website tool. The company pointed people toward general design apps and third-party services, but nothing that reproduces the specific Muse workflow: design freely on a canvas, publish a working website, no code required. That gap is why Muse users have spent years hunting for a real replacement instead of an upgrade.

The pattern: why this keeps happening

Muse is not alone. iWeb, Wix's Editor X, Weebly, Google Business websites, even hosted link-in-bio pages: proprietary visual builders get acquired, deprioritized, or shut down, and their users are stranded with sites they cannot easily move. When a company owns the tool, the format, and the hosting, your work lives or dies on that company's roadmap.

Free software flips the ownership. When the editor is libre and the code belongs to everyone, no single company can end it. If a maintainer steps away, the project can be forked and continued by the community. The tool becomes infrastructure you can rely on, a digital common rather than a product that can be discontinued out from under you. That is the core difference, and for someone who just watched Muse fade, it is the whole point.

What "open source" really means here: free software

People search for "open source", so that is the term you will see everywhere, including in this article. But the word that actually protects you is a stronger one: free software, or libre. It is not about the price, and it is not just about the code being public to read. It is about freedom, the same idea groups like Framasoft have defended for years: the tool belongs to its users and its community, not to a company.

For a designer coming from Muse, that freedom shows up in three very concrete ways.

You own the files. A libre builder outputs standard HTML and CSS that live on your disk. No proprietary project format that only one dead app can open.

You host anywhere. Your site is just files, so it goes on any host: Netlify, GitHub Pages, your own server, a client's server. No forced platform, no monthly ransom to keep the site online.

The tool cannot be taken away. The code is public and the license (AGPL, in Silex's case) guarantees it stays libre. It is a common good: nobody can buy it, close it, or retire it out from under you. Worst case, the community keeps it alive, and you can meet that community at community.silex.me.

This is the difference between "the code happens to be readable" and "the tool is yours by design". Both often travel under the label open source, but only the second one is a real promise. When you are choosing what to rebuild your work in, that promise is the thing worth checking.

The honest trade-off: libre tools usually assume you are comfortable with basic web concepts. You are closer to the HTML and CSS than Muse hid you from. For most designers that is a small step up, and it comes with real ownership in return.

What to look for in a Muse replacement

Before comparing tools, know what you are actually shopping for. A genuine Muse successor should be visual and no-code first, so you design on a canvas instead of writing markup. It should output clean, standard HTML and CSS you can read, host, and hand to a client. It should let you host wherever you want with no lock-in. And ideally it should connect to a headless CMS so content editors can update text and images without touching the design. One more thing worth weighing: whether the tool is truly libre, or only partly open. Keep those criteria in mind as you read.

Three open source alternatives to Adobe Muse

Silex (the closest to the Muse spirit)

Silex is a free, libre visual website builder that has existed for well over a decade, long before Muse and long after it. It is frequently described as a spiritual successor to Muse, and the reasons are concrete: you work visually on a canvas, you do not write code to build the layout, and the output is clean HTML and CSS that you own outright.

Where Muse locked your work inside a proprietary format tied to a dead app, Silex hands you real files. Host them on any static host. Connect any headless CMS when you need editable content. Because it is AGPL-licensed free software, it cannot be discontinued the way Muse was: it belongs to its community, not to a company that can change its mind.

Be clear-eyed about the differences. Silex is a different philosophy from Muse: you own the files and you are a little closer to the underlying HTML and CSS, so some basic familiarity helps. There is no one-click Muse importer, because Muse never exposed a portable format anyone can automatically convert. Moving means rebuilding, not migrating. For a designer who valued the Muse workflow and wants it to be permanent this time, that rebuild buys you something Muse never could: a tool nobody can shut down.

You can try the editor free at v3.silex.me and start from a template. If you would rather have a hand, Silex also offers professional services.

Webstudio

Webstudio is a newer open source visual builder with a polished, modern canvas and strong support for design systems and CSS. It is a serious option if you want a contemporary interface and precise control over styling.

One important caveat, though: Webstudio follows an open-core model backed by venture funding, and open-core is not the same as fully libre. The editor's core is open source, but hosting and some features are commercial and proprietary. In practice the risk profile is close to a freemium tool: a libre core, a paid layer you may come to depend on, and a company roadmap deciding what stays free. That is not automatically a bad deal, and it is worth judging case by case, but it does not carry the same guarantee as a fully libre tool like Silex, where the whole thing is AGPL and cannot be pulled behind a paywall. For a Muse refugee who wants pixel-level design control, it is well worth a look, with that distinction kept in mind.

WordPress (with a visual builder)

WordPress is the most established open source option, and paired with a visual builder like Elementor it gives you drag-and-drop design plus the largest plugin and theme ecosystem on the web. It is heavier than Muse ever was, since it runs a database and a server rather than producing static files, and the visual builders that make it Muse-like are usually commercial add-ons. But if you want a huge ecosystem, built-in blogging, and easy client handoff, it is a safe, long-lived choice.

Comparison at a glance

	Silex	Webstudio	WordPress + Elementor
License	AGPL, fully libre	Open core (libre core, proprietary hosting and features)	GPL, libre (builder is commercial)
Free software values	Yes, a real digital common	Partial: core only, like freemium	Yes for core, add-ons proprietary
Price	Free	Free core, paid hosting	Free core, paid add-ons
Workflow	Visual, no-code	Visual, no-code	Visual with builder
Output	Clean static HTML/CSS you own	Static / hosted	Server + database
Self-host	Yes, anywhere	Yes	Yes
Headless CMS	Connects any	Yes	Built-in CMS
Closest to Muse	Yes	Close	Different feel

Who should choose what

You loved Muse's visual, code-free, own-your-site workflow: start with Silex. It is the closest match in spirit and the strongest fit on this list.

You want maximum design-system control and a very modern UI: try Webstudio, with the open-core caveat in mind: the core is libre, but you may end up depending on its paid, proprietary layer.

You need blogging, e-commerce, or a big plugin ecosystem and easy client editing: WordPress with a visual builder.

You just want the site online with the least effort and do not mind lock-in: a hosted proprietary tool will do it, but you would be signing up for the same risk that just cost you Muse.

How to move from Adobe Muse

Set expectations first: there is no automatic Muse-to-anything migration. Muse never produced a portable, standard project format, so no tool can convert your site cleanly into another builder. Moving means rebuilding. The good news is that a rebuild is also a chance to modernize a site that has not been touched since 2020.

1. Salvage what you can

Your published Muse site is live HTML on your host right now. Save it. Grab the exported HTML and, most importantly, your assets: images, logos, fonts, copy, and the overall layout. These are the raw materials you will reuse.

2. Rebuild the design in your new tool

Recreate the layout visually in Silex (or your chosen tool) using those saved assets. Because you are rebuilding rather than importing, take the opportunity to fix anything Muse did awkwardly, especially responsive behavior and outdated markup. Start from a Silex template if you want a running head start, and drop into community.silex.me if you get stuck.

3. Move content to a CMS if it changes often

If the site has content that clients update, connect a headless CMS so editors can change text and images without touching the design. This is something Muse could not offer and a real upgrade.

4. Publish and point your domain

Export the new site as static files, host them anywhere you like, and repoint your domain. Keep the old Muse export archived until the new site is fully live and checked.

Not migrating? Starting fresh instead?

If you do not have a Muse site to move and you are simply choosing a tool for your next project, the calculus is even simpler. Pick something you own. As a freelancer or designer, the ability to hand a client clean, hostable files, with no platform that can disappear, is a genuine selling point. That is the whole promise of a libre builder like Silex: design visually, ship real files, and never repeat the Muse experience.

FAQ

Can I still use Adobe Muse in 2026? Sometimes. Muse may still launch, but it received its last update long ago and its support and security updates ended on March 26, 2020. It gets no fixes, and it becomes riskier and less compatible over time.

Is there an official Adobe replacement for Muse? No. Adobe never shipped an equivalent visual, no-code website builder. That is why Muse designers have had to look outside Adobe for a real successor.

Is Silex hard to learn after Muse? It is a small step, not a cliff. Silex is visual and no-code like Muse, but it assumes some basic HTML and CSS familiarity because you are closer to the files you own. Most designers adapt quickly.

Can I import my Muse site automatically? No. Muse never produced a portable format, so no automatic migration exists into Silex or anything else. Moving means rebuilding with your saved assets.

Will my SEO survive the move? If you keep the same URLs, page titles, and content, and set up redirects for any changed paths, search rankings generally carry over. A rebuild is a good moment to improve site speed, which helps SEO too.

Closing thought

Muse was a good tool for designers, and losing it stung precisely because it did something few tools do: it let you design freely and still ship a real website. The lesson is not that visual builders are a bad bet. It is that the tool should be one nobody can take away from you.

Free software is that guarantee. Not just code you can read, but a tool that belongs to you and to its community, a digital common that cannot be bought, closed, or retired. If the Muse workflow was what you wanted, Silex gives you the closest version of it, on those terms.
