Offline web design software
Offline web design software lets you build pages on a plane, in a school lab or on capped mobile data, and go online mostly to publish. We compare seven tools, show what each still needs internet for, and where the free Mobirise app fits.
Free for personal and commercial sites.
for the offline desktop app
Edit pages, preview them and use installed themes with no connection. Go online for AI, publishing, your account and new downloads.
Six facts before you go offline
Written by the Mobirise team, who looked up each tool's offline behavior and prices in October 2026.
Offline web design software is a program on your own computer that lets you lay out, edit and preview pages without a connection. You still need the internet to download it, sometimes to activate it, and to put the finished site on a server.
Nothing to pay for personal or business sites. Its one basic theme holds 200+ blocks, and free-plan sites carry Mobirise branding.
Installers for Windows 7 onward, Ubuntu and other Debian-based Linux, and macOS 10.13 onward in two builds: one for M1 to M4 chips, one for Intel.
Placing and moving blocks, rewriting text, swapping photos, block settings, the three preview sizes and installed themes.
Reconnect to generate with AI, to publish, to log in or pay for a plan, and to fetch a new version or a theme you never downloaded.
Pages you build offline become Bootstrap 5 HTML, CSS and JavaScript, and the installed app saves them out with no paid plan needed.
Work started in another tool stays there: the app loads its own projects only, never another builder's site or a purchased template.
The best offline web design software for each need
Three questions narrow it down: what computer you own, how much code you are willing to touch, and whether a one-time price suits you better than a subscription. For several needs, a rival beats Mobirise.
Pinegrow
Opens hand-written HTML and CSS from any project, with a visual view beside the code, and its FAQ says it runs offline. Subscriptions start at $12 monthly. The catch: Pinegrow itself warns that it is hard going if you do not know HTML and CSS.
Mobirise
Build pages from prepared blocks on a laptop with no signal, then send plain HTML to any host once you are back online. One free installer each for Windows, macOS and Linux. The catch: AI drafts and going live both wait for a network, and it cannot load work from other tools.
Bootstrap Studio
A one-time $29 covers Windows, Mac or Linux, and it can import HTML, CSS and JavaScript you already have. Our guide to Bootstrap website builders sets it beside six other tools. The catch: the first launch verifies your key over the internet, and instead of a trial you get a 30-day refund window.
Blocs
Code-free building, offline work in its feature list, and iPad and iPhone versions. Standard costs $112.99 once, tax included. The catch: Mac only, and the free edition cannot export or publish.
RapidWeaver Elements
No coding, offline use in its feature list, and publishing to S3, FTP, SFTP or a folder. The catch: macOS 13 Ventura or newer is required, plans start at $99 a year, and you must subscribe before you can publish.
WYSIWYG Web Builder
Flexible or absolute layouts, FTP, FTPS or SFTP upload, and AI site drafts that can run on a model installed on your own PC. $59.95 once, VAT extra. The catch: Windows only, activation goes online, and its site is silent on offline editing.
8B AI
Type one sentence and get a complete site design at no charge, real HTML and CSS included. Going live needs Pro: $9 for each month, paid a year at a time, with SSL hosting, your own domain and the full HTML. The catch: it lives in the browser, so it does nothing offline.
WordPress on your computer
A local install opens the whole WordPress dashboard with no connection. The catch: it needs a local server stack, and going live means moving the database along with the files.
Bias warning: we make one of these tools, so judge our card harder than the rest. Everything about the others comes from what their makers publish, as of October 2026, and each card states its downside.

Four kinds of offline website software
All four run on your own machine, and each still goes online at certain moments. Knowing which ones tells you what to set up while you have a connection.
Desktop visual builders
Mobirise, Blocs, Bootstrap Studio, RapidWeaver Elements and WYSIWYG Web Builder: you arrange the page on screen and the program writes the files. Online moments: installing, license checks in some, cloud AI, publishing, new themes and updates.
An offline HTML editor
A code editor, or a hybrid such as Pinegrow, works on files in a folder, and any browser previews them from disk. Our guide to visual HTML editors covers the hybrids in more depth. Online moments: extensions, AI assistants, and fonts or scripts loaded from a CDN, which stay missing unless you keep local copies.
Static site generators
Hugo, Jekyll, Eleventy and similar tools turn Markdown and templates into plain HTML, with a local preview server built in. Online moments: installing the tool and its themes or packages; after that, builds run locally. Expect to use the command line: this is offline web development software more than a design tool.
A local WordPress install
A local stack runs PHP, a database and a web server on your machine, so the dashboard opens with no connection. Online moments: plugins, themes, updates and any plugin that calls a remote service. Going live means migrating the database too.
Where working offline pays off
With good Wi-Fi, a browser builder is fine. These four cases are where offline website design software earns its place.
Planes, trains and hotels
Flights, rail tunnels and hotel networks that keep logging you out. Build on the way and publish from the first good connection.
Weak or metered data
A rural line, a phone hotspot with a monthly cap, or an office where everyone shares one slow link. Edits on your own disk use none of that data.
Classrooms and labs
School networks are often slow or filtered. With offline web page design software on each Windows, Mac or Linux machine, students build and preview with the network down.
Client work on your disk
Drafts stay on your laptop until you choose to publish, and you can walk a client through the phone preview in a meeting room with no Wi-Fi.
What Mobirise does with the network off
The desktop app is the Mobirise engine packaged for Windows, macOS and Linux, with the same features as the browser builder. Here is the split.
Offline: build pages
On a plane or in a lab, you still drag blocks onto the page, retype headings and paragraphs, swap images from your disk, and tune each block's spacing, background and columns.
Offline: style and check
Choose fonts and colors in the Style Editor, decide which heading level each title uses, and flip the preview between desktop, tablet and phone.
Offline: what is installed
The basic theme's 200+ blocks and any premium theme you added earlier stay fully usable.
Online: AI
Every Mobirise AI request goes to a server, so no prompt, drawing or screenshot turns into a design while you are offline.
Online: publishing
Sending files to a server or GitHub Pages, and putting the site on a free mobirisesite.com address, wait until you reconnect.
Online: account and downloads
Logging in, paying for a plan, and pulling down a new app version or a theme that is not on your disk yet.
To build a website offline, do three things first: update the app, add the themes you plan to work with, and copy your text and photos onto the computer.
From your disk to the web
The desktop app offers four routes. The first three come with every plan, the free one too, and put no limit on the number of sites.
FTP or FTPES
Upload to any web host, including one your domain already points to. Pick FTPES when the host supports it, since it encrypts the connection.
GitHub Pages
Push the site to a GitHub repository and let GitHub serve it. Static files are exactly what Pages is built for.
A local folder
Write the HTML, CSS, JavaScript and images to a folder, then upload it with your host's file manager or keep it as an archive.
Free subdomain
Once connected, the site can go live on a mobirisesite.com subdomain, HTTPS included, and three such sites are free. Pointing your own domain at a Mobirise-hosted site takes BASE or GROW.
Whichever route you take, a site on the free plan goes out with Mobirise branding; paying for KIT ($149 yearly) drops it.
Backups and a second computer
Two things are worth saving, and only one of them can be edited again.
The project is what you open and change in Mobirise. The published files are what visitors get: HTML, CSS, JavaScript and images that any host serves without Mobirise. Keep both. The exported folder is a full copy of the site, but a frozen one, because Mobirise opens projects, not HTML files.
Back up the project the way you protect other work, to an external drive or a synced folder after each session. To carry on at another computer, install the app and your themes there while you are online. Copies do not merge: if two people edit separate copies, you end up with two different sites.
Is Mobirise the right offline tool for you?
A good fit
- You often work on a laptop with no signal or a data cap
- You want to build from ready blocks rather than code
- Your machines run Windows, macOS or Linux, or a mix, and you want one free app for all of them
- You want plain HTML on hosting you choose, on the free plan too
- You teach a class and need a free tool that keeps working when the school network does not
Pick something else if
- Your real task is reworking an HTML site that already exists, or a bought template: Pinegrow or Bootstrap Studio open those files
- You want AI with no connection: WYSIWYG Web Builder can hand AI work to models on your own PC
- Phones should get a layout of their own, or an element should vanish on small screens only; Mobirise keeps one responsive layout for every device
- You run a blog with plugins, member logins or many authors: WordPress handles that better
- You want to build on an iPhone or iPad: Apple devices get no Mobirise app, and the browser builder needs a connection
- You want free sites with no badge: free-plan Mobirise sites show branding, while a static site generator adds none
Questions about working offline
Is there free offline web design software?
Yes. The Mobirise desktop app costs nothing, business sites included, and edits offline on all three desktop systems; its single basic theme comes with 200+ blocks, and free-plan sites carry its branding. Blocs has a free edition that cannot export. Our free website builder software page lists more options.
Can I use a website builder without internet?
Only one you install. Browser builders, including 8B AI and Mobirise in the browser, stop when the connection drops. Mobirise, Pinegrow, Bootstrap Studio, Blocs and RapidWeaver Elements keep editing offline, though Bootstrap Studio checks its license online on first launch.
Does Wix work offline?
No. Wix is an online builder: you edit the site in a web browser, so it needs a connection while you work. If you want website building software that works offline, choose one of the installed programs in our table and publish when the connection returns.
Does Mobirise AI work offline?
No. Each Mobirise AI request is processed online, so a typed brief, a rough drawing or a screen capture all need a connection. Every request returns four designs, and the free plan allows three a month. For AI on your own PC, WYSIWYG Web Builder can use local models.
Once I reconnect, how does the site go live?
Pick a target in the desktop app: a server of your choice over FTP or FTPES, a GitHub Pages repository, or a folder on your disk that you upload later any way you like. None of these needs a paid plan or caps how many sites you run. Mobirise can also host it free on a mobirisesite.com subdomain, secured by HTTPS.
Will Mobirise open a site I built with other software?
No. The app loads Mobirise projects and nothing else, so neither a hand-coded HTML site nor a template you bought can come in. Recreate the pages with blocks, or keep editing the original files in Pinegrow or Bootstrap Studio, which accept outside HTML.
Which offline tools run on Linux?
In our table: Mobirise (a .deb for Ubuntu and other Debian-based systems), Pinegrow and Bootstrap Studio. Blocs and RapidWeaver Elements need a Mac, and WYSIWYG Web Builder needs Windows. Mac owners have the most choice; our website builder for Mac guide covers it.
Can I build offline on a phone or tablet?
Not with Mobirise. Its only mobile app is for Android, listed on Google Play under the name AI Website Builder: Mobirise, and generating or publishing there needs a network. iPhones and iPads get no Mobirise app, so they reach the builder through a browser, which also needs a signal. Blocs lists iPad and iPhone versions; ask its maker about offline use.
Is coding required to build offline?
No. Blocks, editing right on the page and each block's settings panel handle the layout, while the Style Editor sets fonts and colors. If you know HTML, paid plans add the Code Editor extension for hand edits to a block's or page's markup. New to all this? Start with our easy website builder overview.
What software do web designers use offline?
It depends on how they work, and the four kinds above cover the usual choices. A code editor or a hybrid such as Pinegrow suits people who write the markup themselves, and desktop builders such as Bootstrap Studio, Blocs or Mobirise suit those who lay out pages by eye. Static site generators fit sites built from Markdown, and a local WordPress install fits blogs that depend on plugins.
