Foundation Alternatives as Zurb Foundation Becomes Yeti

Foundation, the responsive front-end framework Zurb started, is changing shape. In a Foundation announcement from September 12, 2026, the team said Foundation for Sites becomes Yeti, a CSS-first, zero-build framework, and that the next major version is a rewrite rather than a port. Foundation 6 moves to a v6 branch that keeps getting bug fixes, and 6.9.0 from September 27, 2024 is its final planned feature release.

That leaves two kinds of reader. Some want a stable framework today instead of an alpha, and some do not want Yeti's FSL licence, which turns into plain MIT only two years after each release. The picks below start with full component frameworks, move to lighter CSS, and end with two email frameworks for people who used Foundation for Emails. Our Bootstrap alternatives guide covers the reverse question if Bootstrap is already in your stack.

Prices below are as of November 8, 2026. Our method is on How we review tools.

Quick comparison

Bootstrap

Bootstrap is the framework Foundation competed with for a decade, and the move is mostly a class rename. Both have a 12-column responsive grid, Sass variables, navbars, modals, dropdowns, tabs and form styles. The practical win is dependencies: Bootstrap 5.3.8 lists only Popper as a peer dependency, while Foundation 6 plugins need jQuery 3.6 or newer, motion-ui and what-input.

Version 5.3.8 from August 26, 2025 is the stable line, and 6.0.0-alpha.1 came out on October 8, 2026. The team has said v5 stays supported and will get a 5.4.0 release before any end-of-life date is announced.

Best for: Foundation 6 sites that want a stable, widely known framework with no jQuery.

Pricing:

• Free, MIT licence
• Paid themes sold by third parties

Watch out for:

• Bootstrap 6 is also a big rewrite. The Bootstrap 6 alpha post drops the UMD bundle, makes plugins ESM-only and raises the floor to Chrome 130, Firefox 132 and Safari 18.
• Default Bootstrap sites look alike, so expect Sass theme work for a distinct brand.

Official site: Bootstrap.

UIkit

UIkit replaces Foundation's plugin set with more of its own. UIkit has 81 components, including sliders, lightboxes, sticky navigation, scroll animation and an off-canvas menu, all driven by its own JavaScript with no outside dependencies. Foundation users who leaned on Orbit, Reveal and Off-canvas find equivalents here without jQuery.

The latest release is 3.25.29 from November 2, 2026, MIT-licensed and maintained by YOOtheme. Theming works in Less or Sass, and YOOtheme sells a WordPress and Joomla page builder, YOOtheme Pro, that outputs UIkit markup.

Best for: Marketing and content sites that need rich interactive components in one package.

Pricing:

• Framework: free, MIT licence
• YOOtheme Pro: Standard €129 per year (3 sites), Developer €329 per year, Agency €529 per year, plus VAT in the EU

Watch out for:

• The uk- class prefix and attribute-based components mean every Foundation template needs rewriting, not just renaming.
• The UIkit repository belongs to YOOtheme GmbH, and the company's business is mainly its paid builder.

Official site: UIkit.

Tailwind CSS

Tailwind suits Foundation users who mostly used the XY Grid and utility classes and fought the component styles. You build layouts with classes such as grid, grid-cols-12, gap-4 and md:col-span-6 straight in the markup, and the build keeps only the classes you use, so there is no framework look to override.

Version 4.3.5 was released on November 6, 2026 under MIT, and v3 has an LTS line, last updated to 3.4.19 in December 2025. Tailwind Labs also sells Tailwind Plus, a one-time purchase of UI blocks and templates.

Best for: Teams with a designer who want full control of the look and a small CSS output.

Pricing:

• Framework: free, MIT licence
• Tailwind Plus: one-time purchase with lifetime access

Watch out for:

• Foundation's _settings.scss workflow has no direct match, because the Tailwind compatibility page rules out pairing v4 with Sass, Less or Stylus.
• Tailwind Labs cut three of its four engineers in January 2026 after revenue fell almost 80 percent.

Bulma

Bulma is a good match for Foundation sites that used the CSS and wrote their own small scripts. Columns, cards, navbars, tabs and form controls come as readable classes like columns, is-half and navbar-burger, themed with Dart Sass and CSS variables, with dark mode built in.

Version 1.0.4 dates from April 19, 2025, MIT-licensed and funded through Patreon and GitHub sponsors. It ships both Flexbox columns and a CSS Grid layer.

Best for: Server-rendered sites that want ready components with zero JavaScript to load.

Pricing:

• Free, MIT licence
• Optional sponsorship

Watch out for:

• There is no JavaScript at all, so the mobile menu toggle, modals and dropdowns need your own code.
• Releases are infrequent, so check open bugs in the Bulma repository before you commit to it.

Official site: Bulma.

Pico CSS

Pico is the minimal option for anyone who used Foundation on a docs site, a prototype or an internal tool and found it heavy. It styles semantic HTML elements directly, offers a class-less build that needs no classes at all, and includes 20 precompiled colour themes for light and dark mode.

Version 2.1.1 from March 15, 2025 is current, under MIT. One stylesheet link replaces Foundation's CSS, its JavaScript and its jQuery dependency.

Best for: Small sites and prototypes where good-looking default HTML is enough.

Pricing:

• Free, MIT licence

Watch out for:

• No JavaScript ships with it, and the Pico modal docs say you need your own script to open and close modals.
• There is no grid system on the level of Foundation's XY Grid, only a basic grid helper.

Official site: Pico CSS.

MJML

Foundation for Emails used Inky tags to hide the table markup that email clients demand. MJML does the same job through a tag language of mj- elements, such as mj-section, mj-column and mj-button, and compiles them into responsive HTML with nested tables and inline CSS. The MJML site says Mailjet developers created it in 2015.

The current release is 5.4.1 from September 10, 2026, MIT-licensed, and a 6.0.0-alpha.1 build appeared on October 9, 2026. It runs as a Node.js package and has a live online editor for quick tests.

Best for: Developers and marketers who want responsive emails without hand-writing tables.

Pricing:

• Free, MIT licence

Watch out for:

• Its tag set is its own language, so Inky templates need a full rewrite.
• Version 6 is in alpha, so another round of template changes may follow the 5.x line.

Official site: MJML.

Maizzle

Maizzle is the email route for teams that already write Tailwind on the website. The Maizzle site calls it a modern email development framework for building production-ready emails with Vue and Tailwind CSS, using reusable components tested across major email clients.

@maizzle/framework 6.3.2 was published on November 3, 2026 under MIT. The same team sells Mailviews, a collection of email templates and components you buy once and own.

Best for: Front-end teams who want email templates in the same Tailwind workflow as their site.

Pricing:

• Framework: free, MIT licence
• Mailviews templates: one-time purchase, price not published

Watch out for:

• It assumes you know email-safe HTML. The components help, but it is more hands-on than MJML's tag language.
• It needs a Node.js build step, unlike dropping in a compiled Foundation for Emails CSS file.

Official site: Maizzle.

How to choose

When to stay with Foundation

Stay on Foundation 6 if your site works and you only need bug fixes, since the v6 branch keeps getting them and Foundation for Sites 6 stays MIT. Foundation for Emails is still released too, with 2.5.1 from March 12, 2026. If you want to follow the project forward, the Yeti repository has alpha builds, but wait for beta before you plan a production migration.
