TL;DR: Websites display static content for passive viewing (like blogs or business homepages), while web apps are interactive software that allow users to log in, create and manage their own data, and perform specific tasks with personalized experiences (like Gmail, Facebook, or Airbnb). The key difference is interactivity: websites are one-way information delivery, whereas web apps enable users to actively participate, create content, and interact with other users through features like user profiles, databases, and complex functionality.
Most people think of the internet as a collection of websites. But if you've spent any time in the web development space, you've probably heard the term "web app" used just as often—sometimes interchangeably, sometimes not.
The distinction matters more than you might think. Choosing the wrong one can mean rebuilding from scratch later, or paying for complexity you don't need.
In this article, we'll clarify the difference between web apps and websites, walk through real examples of each, and help you decide which is right for your goals.
What is a website?
“Website” is often used as a colloquial term for “anything online that I access via a browser,” which isn’t quite true.
Technically, a website is a group of related web pages published by the same owner on the same domain that displays static content. Most websites are used for information or marketing purposes, where visitors are passive consumers who can't interact with or create data.
Typically:
- Websites have limited interactivity beyond displaying content, such as subscribing to a newsletter or sharing a post to social media
- Only a website’s owner can add and edit content
- Websites deliver a standard experience to every visitor
For example, websites include sites like:
Most local restaurants, small businesses, service businesses, and blogs qualify as websites.
Some companies may have both a website and a web app, such as Hubspot or Bubble. They have static websites for marketing, with content and information you can access passively. But they also have a web app that allows you to log in, create and edit your own data, and have an interactive experience.
What is a web app?
As Sam Morgan, one of our internal Bubble Developers, puts it: "A web app is an interactive piece of software that runs in your browser." Unlike websites, web apps allow users to log in, create and manage their own data, and complete specific tasks through personalized, dynamic experiences.
“A web app is an interactive piece of software that runs in your browser.”
Web applications tend to also:
- Allow users to log in and take actions like making purchases, connecting with other users, adding and editing data, and so on
- Allow user interaction with content (i.e., creating and sharing their own posts vs. just reading posts)
- Allow users to create custom experiences based on their data (like Spotify's personalized playlists or Netflix's recommendations)
Common web applications include:
- Gmail (your email inbox is unique from everyone else’s, and you can compose, send, and manage your own emails)
- Facebook (everyone’s Facebook experience is unique, and you can add your own content and interact with others’)
- Bubble (you can use our platform to create and publish your own web apps, not just view static content)
- Airbnb (you can add your own listings, book trips, interact with other users, and so on)
Web app vs. website: 7 key differences
The core difference: A website displays static content for visitors—everyone sees the same thing. A web app provides an interactive experience where users accomplish specific tasks with personalized data.
Sam Morgan describes the difference like this:
“A website is something that a user reads; a web application is something that they interact with. There are a lot of nuances to this, though. A simple contact form that a user fills out may not be enough on its own to make something a web app."
This chart summarizes the key differences:
| Feature Name | Websites | Web applications |
|---|---|---|
| Interactivity | Websites deliver a passive visitor experience. Visitors consume content; they don't create it. | Web apps deliver an interactive user experience, where users can add, edit, and interact with their own or others' content. |
| Scalability | A website can accommodate many visitors, but it doesn't allow you to scale a product. It may provide a solution for a single client or problem. | A web app is a scalable product that can accommodate a growing number of users. It can provide solutions for any number of users, clients, or teams. |
| User profiles | Websites typically only have one authenticated user: the website's owner. Visitors to the site don't log in (or if they do, it's for very limited functionality), and the app experience is not shaped by their contributions. | Web apps have many users. Anyone can create an account to add and edit content. An Instagram user can add their own photos; an Airbnb user can add their own listings or book vacations. |
| Functionality | Websites use static pages with limited functionality. Visitors may fill out a form or subscribe to an email list, but they can't edit or change content. | Web apps include more complex functionality, such as allowing users to add or edit data, interact with other users, and so on. |
| Underlying tech | Websites can be created with simple HTML or JavaScript. | Web apps have more functionality, so they require more advanced programming. They require databases, frameworks, and a more extensive user interface. |
| Cost | Websites can be developed very quickly and affordably, especially if you use a basic website builder like Squarespace. | Web apps often require more resources to develop, especially if you're coding from scratch instead of using a no-code solution. |
| Development | Websites can be developed simply using a website builder. They don't require a lot of prior knowledge or experience. | Web apps require more development knowledge, such as an understanding of UX, UI, frontend and backend technologies, and so on. |
Let’s break down each of these differences.
Interactivity
This is probably the biggest distinction between websites and web apps.
❌ Websites allow interactions only from the site’s owner, and basic interactions from visitors.
Common website interactions include:
- Navigation: Clicking links and using menus to browse pages
- Basic engagement: Filling out contact forms
Web app interactions include virtually anything users need to accomplish tasks, such as:
- Account management: Creating profiles and managing personal settings
- Data creation: Adding and organizing photos, to-do lists, or posts
- Social features: Adding friends, joining teams, or messaging other users
- Commerce actions: Adding products to carts or wish lists
Scalability
Scalability highlights how many users you’re able to serve with your platform.
❌ Websites only provide a solution for one individual or team.
Andrew Vernon, senior Bubble Developer, contrasts them this way:
“For instance, a real estate website might allow one company to post their home listings and take requests about those listings. Whereas a real estate web app (like Zillow) might allow thousands of companies to post all of their home listings, along with information about their business, and to dynamically take requests about any of those listings.
For founders and developers, it's the difference between being able to build a site for one company and their users, or building software that could serve many companies and ALL of their users. The opportunities and end results of the dynamic systems that come from web applications provide a massive opportunity to serve a much larger user base.”
Web applications are globally accessible via a web browser on any device. With Bubble, you can also build native iOS and Android apps from the same platform, all sharing the same backend—giving you unlimited reach across web and mobile.
User profiles and authentication
User profiles are a key indicator of whether something is a website or web app.
❌ Websites don’t allow sign-ons, or offer limited functionality once you’re logged in.
For example, many online publications (i.e., The Verge, The New Yorker) allow visitors to sign in, manage their subscription, and comment on content. While these sites are primarily content-focused, they incorporate some interactive features typically associated with web apps.
However, on a web application like Medium or LinkedIn, users can create their own profiles, add content, interact with other users directly, send messages, and so on. Their experience of the app is changed and shaped by their actions.
Functionality
Web applications offer much more complex functionality than websites.
❌ Websites don’t have much functionality beyond displaying static content.
John Carter, associate Bubble Developer, expands on this:
“Both are accessed in a similar way. However, a web app allows far more complex and custom functionality to happen. You can participate in social networks (follow friends, share media posts), keep track of sales leads (create new leads and update existing), and view last month's sales metrics (change table filters and create new visualizations).
The way web applications shine is by giving the ability to the end user to truly customize their experience and contribute to the web app's ecosystem.”
For example, with Bubble’s web app, you can:
- Sign up for an account to store your personal projects
- Design wireframes and mockups of your own web app
- Add databases and data to your own app
- Share your designs with other team members
- Launch and host your own web applications
Underlying technologies
The underlying technology of a website is much simpler than a web app.
❌ Websites can be built using basic HTML or CSS.
For example, a productivity web application might have data types like users, projects, and teams.
On Bubble, AI can generate your database structure, data types, and privacy rules automatically — or you can build and modify them visually. You can use database triggers and workflows to let users edit and interact with data through your app's interface, and the Bubble AI Agent (beta) can help troubleshoot or explain your database setup.
For example, database triggers and workflows allow you to:
- Connect different types of data
- Hide, show, or animate elements on the page
- Create search functionality for your app
- Manipulate personal data and view other users’ shared data
- Add and edit their profile for your web app
- ... and more!
Cost
Generally, web applications are more expensive to develop than websites.
❌ Websites can be built with simple, drag-and-drop website builders.
Traditional web app development costs include:
- Development teams: Multiple developers working for months or years
- Ongoing maintenance: Regular updates and bug fixes
- Infrastructure:Hosting and server costs
However, modern no-code platforms have changed this equation. Tools like Bubble make web app development as accessible as website builders — combining AI generation with visual editing to eliminate the need for expensive development teams.
For context: Bubble offers a Free plan for development and testing, with hosting included (with limitations).Paid plans start at $29 a month for additional features and capacity as you scale.
Development requirements
Web apps are generally more complicated to develop than websites as well.
❌ Websites are traditionally easier to build and maintain.
If you’re coding from scratch, building all of this out requires a team of developers and designers, plus servers, a hosting solution, and so on.
Again, modern no-code, AI app development platforms have simplified web app development significantly. With Bubble you can design interfaces, set up databases, and configure workflows without writing code — reducing development time from months to weeks and eliminating the need for a full development team.
Examples and use cases
Here are real examples of each category in practice.
Website examples
Websites are best for presenting information. Common examples include:
- Marketing sites: A company homepage that explains its services, like Levain Bakery
- Blogs and news sites: Publications that display articles for reading, like TechCrunch
- Portfolios: A photographer's site showcasing their work
- Informational sites: A local government page listing park hours
Web app examples
Common examples include:
- Social networks: Facebook and X (formerly Twitter) for creating profiles and sharing content
- SaaS tools: Trello for project management or Figma for design collaboration
- E-commerce marketplaces: Airbnb for listing and booking properties
- Email clients: Gmail for managing personal inboxes
- Financial apps: Banking platforms for account management and transactions
- Cloud storage: Google Drive or Dropbox for file management
When to choose a website
You should build a website if you need to:
- Create a marketing presence for your company
- Publish articles or blog posts
- Showcase a portfolio of your work
- Provide contact information and a business address
- Display a restaurant menu or list of services
For one-way communication needs, use a simple website builder for the most straightforward and cost-effective solution.
When to choose a web app
You should build a web app if you need users to:
- Log in to a personal account or profile
- Create, edit, or manage their own data (like posting photos, managing projects, or creating listings)
- Interact with other users (like sending messages or following accounts)
- Perform complex tasks like booking, purchasing, or analyzing data
- Have a personalized experience based on their inputs and history
If you anticipate needing any of this functionality in the future, it's often better to start with a web app to avoid rebuilding later.
