Introducing Sitely 6

Sep 10, 2025

What’s the best way to kickstart your next project? A new version of Sitely with amazing new features!

We’re super happy to introduce a major new Sitely update today, version 6. It’s been a while. Last time we had a major release we used to still call it Sparkle, it feels good to finally release all the features we have been working on .

Two years that feel like two decades, in terms of everything that has changed. AI is that much more prevalent, people search more using AI chat instead of search engines, and even the regular “old” search engines show AI-powered answers.

So with all that, does a website still make sense? What’s the big picture? Is the web still relevant in 2025 (and beyond)?

In a Verge interview, Google CEO Sundar Pitchai says their metrics show web searches growing, and they are sending traffic to an increasing number of websites. Also he acknowledges that “AI agents” will be scouring the web on behalf of their users, however that will be a different web. Pitchai’s metaphor for the “agent web” is AI agents are like customers ordering takeout at the restaurant’s entrance, compared to the full dining experience of the actual website. So a different focus and different goals, that don’t detract from the full web experience.

In other words, AI doesn’t change the relevance, legitimacy and in fact importance of your website, it will still show up in AI-powered results, if search engines (or chatbots) deem it to be relevant. Exactly like a list of 10 links of classic search. Except, according to Pitchai, web searchers tend to find the AI results more relevant. This confirms what we have always asserted: that search engines were always going to understand your content more and better, in a more human and semantic way. Turns out AI and LLMs are doing that today, and while search engines initially dropped the ball they’re now quickly catching up, so you can expect fewer and fewer search engine optimization “tricks” to work. Understandably the whole SEO industry is up in arms and claiming they still have the same relevance that they had when they managed to find blind spots in Google’s algorithm. Our advice to you is unchanged: continue to write clear, understandable, truthful, coherent content, focusing on giving the best possible answer to each “question” (be it search query or AI chat question) on its own web page. That’s what Sitely’s “Optimize for search engines” option, and related assistant messaging, is focused on.

About AI’s role in generating websites, you will certainly find many “growth hackers” promising that AI can do it all (spoiler, they’re looking for your attention). As discussed in our blog post on the topic, what’s actually going on is they’re shooting first, then claiming whatever they hit always was their intended target. They try 100 times, pick one result, and claim it to be representative of the AI abilities. Or in other words, it’s significantly harder to get the AI to deliver exactly what you have in mind, particularly when context or relationships are expressed visually or spatially, something that as humans we interpret intuitively, but is not fully expressed in plain language, the main currency of “large language models”. This is not to say AI isn’t mightily impressive, but understanding the limitations is what helps us build a pragmatic tool, where AI is helping out when it makes sense to accelerate some of the work, as opposed to creating busywork or expectations that can't be met.

But even more importantly, the human component of composing text, images and a layout are what distinguish your contribution to the web from AI “slop”, the rambling incoherent text with average opinions, average tone and average-but-please-everybody style. The mcdonalds-ification of web content, might fool someone some of the time.  You, and we all, can do better. If building a website wasn’t important, why would AI bots, and now Cloudflare, want it so badly?

The elephant in the room with this release is the upcoming macOS 26 Tahoe and their new Liquid Glass user interface. We’re releasing Sitely 6 with general Tahoe compatibility, but no Liquid Glass adoption at this stage. We’ll be eagerly following Apple’s iterations and refinements, to offer you all a great experience when the UI is a little more ripe.

Without further ado, here’s what we’re adding in Sitely version 6, to empower you to build the next great website.

Slider mode

Image/video grids now have a new layout setting, letting you pick a horizontal slider mode, with a variety of features for interactive and automated modes. You can try it right here with a few sample images, this is an infinitely repeating slider with interaction enabled of the flow layout, and animation (when not interacting).

The grid also has a couple more useful improvements:

  • You can now set the image lightbox to extend to the full browser window
  • You can now customize individual cell backgrounds, instead of the background applying to all cells at once

Before/after image widget

This is perfect for showcasing image differences of any kind, often used in real estate, photo retouching, illustration, restoration and art. This widget also has a many configuration options to make it work in the context of your pages. Here’s an example 2000 vs. 2012 image of the Amazon rainforest deforestation:

‍In-window preview

‍With the in-window preview you can press CMD-R (File Arrow Right Preview Website) or click the preview button to instantly switch to a built-in browser that shows the page. This makes it super quick to test anything that the is editable in the canvas but not interactive, such as animations, videos, hover effects and so on.

‍You can still also use the preview in an external browser, which is ideal for testing a layout in different browser engines (the internal one is essentially Safari), but also for a multi-monitor or large screen setup, where you can set it up in a way where it’s always visible, side by side to the editing. The in-window preview is likely much more useful on a laptop or small screen setup.

‍And as far as external browsers go, we also added support to directly open several other browsers, including Vivaldi, Arc, Opera, the Safari Technology Preview and Mobile Safari (in the Xcode simulator), if you have them installed.

Second generation AI website creation

Sitely's upgraded AI website generator, now available in version6, kickstarts your project with a ready‑to‑edit layout complete with rich text and royalty-free images, dramatically reduces your design friction . Once the AI lays down the core structure, you take over, customizing content, visuals, and interactions in Sitely’s canvas.

The AI generator elegantly blends the speed of AI automation with the freedom of manual refinement, striking a balance between inspiration and control.

AI website generation now fully unlocks the power of built-in functionality, giving you control over your site’s color palette, enabling synchronized menus, and other powerful features such as layout blocks built as FAQ sections. It also produces more intelligent, tailored text that aligns more closely with your directions.

‍Image protection

‍How you feel about protecting images is a personal matter. Inevitably putting something on the web makes is public, and might invite someone to steal it. While someone who’s determined to steal your content is always going to find a way, there are a few things that can be done to mitigate, while still showcasing your work.

‍At the simplest level you can prevent the image from being dragged from the page, or saved after a right click.  For many of our customers this has historically been a “good enough” solution that they were seeking.

‍Embedding copyright information in the image, which will be taken from the original image if available, is often also a good solution. So for example photographers will find it from the camera or from their processing software such as Lightroom.

‍Both these techniques are not going to help with slightly more sophisticated users, who will view the page source, or crawlers that download images on behalf of AI systems or image search services. So for those we developed a novel “Hide from Search and AI” option, that is not impossible to work around, but needs a focused adversary who is technically knowledgeable and wants your image specifically.

‍Ultimately if you recognize that the image will just be grabbed by who wants it, but still need to show it, you can opt to reduce the image resolution, so that whoever manages to grab it never has the best image quality.

Checkbox options for image protection, including preventing drag/context menu, embedding copyright metadata, hiding from search and AI, and reducing image resolution.

‍AI bot protection

‍We can certainly be of two minds about AI, in it being both an opportunity and a threat. This feature is designed to address the negative aspect of AIs training on your content. You can now prevent AI crawlers from accessing your website and collecting the page text for training purposes.

‍Hover everything

‍Hover animations are now available on most page elements, to add some bounciness even to something that is not a link.

‍Gallery borders, rounding and shadow

‍The image gallery slides can now can be configured with borders, rounding and shadows. This helps you match the gallery to the overall style of a page or section, or can be used for fun effects like this one.

‍We also added customization options for the left/right arrow shape and size.

‍Privacy compliance enhancements

‍The cookie banner now support all the cookie types (e.g. functional, analytics, marketing) that compliance with regulation requires you to ask the site visitor about. The first time you open an older project, you will be prompted to update your cookie banner with the new checkboxes and buttons, something you can also defer to a later time.

‍The cookie types your site visitor picks on the banner will be matched up with the third party content on your pages, so that only elements matching the user selection is unblocked. For example if a site visitor doesn’t select “marketing”, most third party content won’t be unblocked.

‍For code embedding, where you paste some third party code provided by a vendor, by default it’s assumed that it will produce all types of cookies, and it’s up to you to check with the vendor whether they do not, and select the appropriate cookie types in the embed settings.

‍All third party content, whether built-in or in code embed elements, now supports two-step activation. This lets a site visitor unblock a specific embed even if they denied consent when first visiting the website, for example they want to see a Google map of your store even if they denied consent to all cookies. In the case of TTDSG in Germany, it’s a requirement to block third party content and unblock it individually, even if the site visitor accepted the cookie banner and expressed consent.

‍The user choice of cookies needs to also be reflected in Google Analytics and Tag Manager, a relatively recent change in their service in what they call “Consent Mode 2”. Sitely’s privacy management acts as a consent management platform in integrating with Analytics and Tag Manager, supports this, which allows for richer data collection in full compliance, for users that consent to all cookies.

‍When you first open a project file from an older Sitely version, if you had the privacy feature active, you’ll be prompted to update the cookie banner, and to fix the cookie classification of any embed element.
If you want to postpone that you can go to the privacy page, select the cookie banner, and click the update button in the settings. The update prompt and manual button add the missing cookie type checkboxes, and the “accept selected” button. You then need to update their position and style to match your existing ones.

Checkbox options for cookie preferences with "Necessary" checked, and two buttons labeled "Accept All" and "Accept Selected."

‍Accessibility

‍A second compliance area, comparable to the privacy one in many ways, is that of accessibility.

‍While we dislike seeing privacy and accessibility weaponized to drive regulation, and scare website owners into costly legal services, making your website accessible to everyone remains a basic responsibility, one that benefits us all, including ourselves, in a less fortunate future. What Sitely can do to help is making it as streamlined and simple as possible.

‍Sitely websites, by virtue of being very plainly coded, were already inherently very accessible. In version 6 we have added several key refinements to ensure the website is as accessible as possible.

‍The one caveat is that accessibility compliance is complex and nuanced, so much so that there isn’t a single tool that will give you a 100% compliance assessment, most will only point out some of the more glaring issues. For this reason we consider getting to full coverage of the accessibility requirements a process that will require progressive updates and refinements. But despite that, version 6 brings code improvements, some required new data to enter, and state of the art accessibility checking in the assistant.

‍In wording of some local regulations the website needs “full keyboard accessibility”, and you can count on that for websites published with Sitely 6, in addition to dozens of improvements.

‍As an example of new data entry, a button with a label doesn’t need anything special for accessibility to work with it, but if the button contains an image and no label, it will need you to set a new “Link Description”. Sitely’s website assistant now has a check for that.

‍Another new type of information you need to add for accessibility purposes is the relationship between form fields and their label. For example a form asking for an email address using a text input and a text label will now clarify the relationship by expressly setting the text block as the label for that text input.

‍Of course there’s a very common pattern that is to use the placeholder as a label of sorts, a more modern and space efficient design. So we added support for that directly, and you can set the placeholder as a floating label, and make that the accessibility label all at once. 

‍Another accessibility issue is when the text contrast over the background is insufficient for good readability. We have a check for that as well. What’s unique in Sitely, meaning we know of no tool that will do this for your website, is the check for text contrast over a background image, where Sitely will check each individual character for contrast and provide a detailed visual pinpointing the issue, like this.

‍A time consuming step in adding accessibility to a website is to add descriptions to images, which is well in range of what an AI can do today, so we use OpenAI for this and send a small version of the image over to their servers and add the description for you.

‍Finally, the canvas in Sitely itself now includes accessibility support, and can be navigated via assistive technologies, such as the macOS VoiceOver feature.

‍Color gradients

‍We gave gradients a huge upgrade. In addition to being able to pick multiple gradient steps, and radial and conical gradients, it’s now possible to pick the color space for the color ramp. While color spaces can be hard to visualize, the idea is that instead of a continuous variation of red, green, blue (natural on a computer screen), it’s now possible to have a continuous variation in color parameters that are more akin to human vision. The more natural color space is called “OKLCH”, and a gradient in OKLCH tends to preserve the hue or luminosity, whereas RGB gradients tend to end up with color hue or saturation that’s unrelated to the gradient starting and engine points. 

‍To make this super clear we added a visualization of the gradient path through a hue color wheel, you can see how the three blending path options affect the gradient.

‍The new gradients can be applies to box and and button backgrounds and,  new in version 6, to boxes and button borders as well.

‍Applying the gradient border is a matter of picking the new gradient style, you can then use the same gradient settings. With buttons the additional twist is you can set a different gradient for the mouse hover, so have the border gradient that changes on hover.

Miniature effect

A narrow depth of field in photography generally only occurs when you're taking a picture extremely close to a small object, like when photographing a miniature model. So a circular blur that selectively blurs the area around a sharp focal point mimics the shallow depth of field, and gives the illusion of it being a picture of a miniature model. This works best when the starting image is mostly in focus, and there is a subject you can “focus” on, like in the example here.

‍Contact form improvements

‍Contact forms have several new great features, to help with more complex data entry, as well as streamline simpler home pages.

‍For a simpler contact form experience in smaller websites, you can now replace the contact form thank you page with a thank you popup. This communicates the successful email delivery without switching to a different page.

‍A new setting in the option selection lets you select similar options to “On Click” settings (go to a page, open an email, etc), and that includes opening a popup or disclosing a hidden layout block. This lets you create longer forms that span layout blocks and popups without making the user experience more complex. The form submission will consequently now let you pick input fields from the base page and from other layout blocks or popups, all to be delivered in a single email.

‍To cope with longer and more complex forms, you can now opt to format the contact form email on two side by side columns, the email will be sent as text and HTML.

‍A common contact setup issue is the choice of a “From” email address that can't work with your domain, due to domain-level anti-spam settings. Sitely will now check and detect those settings, and inform you of potential deliverability issues.

‍Sitely 6 also adds the ability to integrate the result of a calculator smart field into a contact form email.

‍Finally, spam bots are evolving and we have consequently hardened the bot detection, that like in earlier versions doesn’t require any interaction from the site visitor (no annoying captcha) and doesn’t expose them to third party services.

Image compression improvements

Sitely 6 adopts a new image compression algorithm for JPEG images that’s both fast and good. In their research, the JPEG XL team worked on JPEG compatibility and managed to create a JPEG-compatible image encoder that uses the underlying math and algorithms of JPEG XL. It’s so good the JPEGs are generally smaller than the equivalent webp images. In both cases a perceptual comparison of the image is performed to the original, so it’s apples to apples.

We’d be tempted switch the defaults to JPEG-only generation, but Google’s Pagespeed will then claim that you need to switch to webp/avig to save space, and penalize you for it. You don’t really save space unless you’re willing to sacrifice visual quality. Pagespeed should know better, ironically JPEG XL is developed by Google engineers.

Many assorted additions

There are many smaller additions that don’t belong to an individual category, but still are great additions to help with your website:

  • You now add an on click action to switch language in multi-language websites, that always switches to the configured page in the destination language
  • You can now integrate Rive animations, enabling lightweight, interactive motion graphics
  • The page language is now used for applicable on-page interface elements
  • Popups now can be set to auto-close at a defined time interval after they're opened
  • Publishing setup is now improved and streamlined, with better detection of edge cases and enhanced server compatibility
  • You can now perform simple calculation in inspector text fields, like say a box is 37+14 pixels wide
  • You’ll now see a warning if an on click action is placed in a group that already has an on click action, the inner link was previously silently ignored
  • You can set the canvas zoom level to "Fit Page Width" to switch between devices and always have a zoomed in view
  • We added the Korean localization of the user interface

How to get it

If you’re new to Sitely you can download it from our website and try it for free for 14 days (or use the limited free version forever).

Regardless of what license you purchased, you can use Sitely v6 (without the new features) at no additional cost. This is because we separate software version from license version, and it’s actually best if you use the latest version even if you don’t upgrade. It will be more stable and more compatible, and occasionally we open up a previously paid feature to everybody.

If you purchased a Sitely subscription you will be able to access all the new features immediately.

If you purchased Sitely 5 after January 1st 2025, you can upgrade for free, just update Sitely, the license window will confirm you can use version 6 features.

If you purchased Sparkle or Sitely version 5, or an upgrade from a previous version to version 5, before January 1st 2025, you can  purchase the license upgrade at half of the list price: $59.99/€69.99/£59.99 for the Pro license, $39.99/€44.99/$39.99 for the Personal license.

Finally a full Pro license is $119.99/€139.99/£119.99 ($79.99/€89.99/£79.99 for a subscription), and a Personal license is $79.99/€89.99/$79.99. The pricing hasn’t changed in 3 years, so considering the crazy high inflation of the last few years it’s effectively 20% cheaper than 3 years ago.

If you’re looking to test Sitely for the first time, go ahead and download it from our website.

If you have Sitely downloaded to your Mac, you can run the updater by selecting “Check for updates” under the Sitely menu at the top of the screen.
