WeWeb & Xano vs Bubble: Which tools should you use?

Why compare these two approaches?

We started by building most client apps in Bubble.io. As projects became more complex, we looked for more control over the frontend and backend. We already used Xano for the backend and chose WeWeb for the interface.

The comparison grew out of that work. Its most useful distinction is still how your team divides responsibility between interface, backend logic and data.

The split in WeWeb and Xano

WeWeb interface Screens, components and frontend interactions
Xano backend API endpoints, business logic and authentication
Xano database Records, relationships and indexes

Bubble combines frontend and backend in one platform. With separate tools, the API joins the two parts.

All-in-one tools vs separate frontend and backend tools

Separate frontend and backend tools suit apps with complex features and growing usage. An all-in-one platform is simpler for smaller apps and non-technical builders.

Bubble.io combines the frontend and backend in one platform. With WeWeb and Xano, you build the interface and backend logic in separate tools.

What are the main advantages of using separate tools?

Control: You have more control over the functionality of your app.
Separate migration paths: You can replace the frontend or backend independently, although each still has platform-specific logic to migrate.
Performance control: A separate backend gives you its own query, caching and capacity controls. The result still depends on how you design and measure the application.

What are the advantages of using an all-in-one tool?

Simplicity: Building is simpler and faster because the frontend and backend are already connected.
Pricing: You pay only for one development platform.
Version Control: Different environments of your app are automatically synced for back-end and front-end.

How did we compare Bubble with WeWeb + Xano?

We compared the work involved in building interfaces, frontend logic, and databases, along with performance and pricing. We also considered requirements that affect specific projects, such as HIPAA or GDPR compliance.

UI editor: building the frontend

WeWeb uses a visual editor with concepts closer to traditional development. Bubble’s editor is easier to work with, especially for builders without a technical background.

Components

WeWeb: Uses components to create re-usable elements that can be used across your entire application or shared between projects. You can define properties, local variables, workflows, formulas, and triggers to build a shared component library.
Bubble: Uses “re-usable components”. Properties pass data into reusable components. Check how shared components interact with the rest of your intended screen.

Styles/classes/design system

WeWeb: Uses the equivalent of CSS classes. You can define colors, typography, and spacing and apply multiple classes to elements.
Bubble: Uses “styles” (visual variants). The disadvantage is that it doesn’t allow you to combine multiple styles; you can only apply one style per element.

Responsiveness

WeWeb: Uses the concept of breakpoints (similar to Webflow). It makes it easier to define responsiveness, with styles for desktop, tablet and mobile described in its responsive design guide.
Bubble: Uses conditional logic (e.g., if screen size < X, change font). This offers flexibility for specific values, but requires individual definition and some properties can’t be changed conditionally, necessitating duplicate elements for mobile.

Two ways to organize the build

	Bubble	WeWeb + Xano
Interface and data	One platform	Separate frontend and backend
UI styling	Styles applied to elements	Classes combined on elements
Team coordination	Shared platform setup	An explicit API connection

These are differences in how the work is organized. The best fit depends on the app and the team.

Front-end workflows/business logic

WeWeb frontend workflows are visually clearer, while Bubble has more predefined actions.

WeWeb: Complex workflows are created as diagrams, which are visually clearer and easier to understand.
Bubble: Offers more pre-built actions out of the box, but complex business logic can become difficult to manage (“a mess”).

Database management

You have more control in Xano, but it is easier to manage the database in Bubble.

Xano: Full PostgreSQL management. Includes DB triggers, custom indexing, and an Excel-like UI. It mimics traditional SQL logic.
Bubble: Requires less database configuration, which can help non-technical users. It supports DB triggers but lacks control over DB indexes for query optimization.

Custom code

Using custom code in WeWeb & Xano feels much more native than in Bubble.

WeWeb: Supports reusable JavaScript functions and imports of Vue.js components from GitHub.
Xano: Allows JavaScript “lambda functions” for complex data transformations.
Bubble: Requires external plugins to run plain JS, and code is often not easily re-usable across the app. However, you can create custom plugins for the marketplace.

A request across separate tools

User action WeWeb screen
API request
Backend checks Xano logic and permissions
Result in the UI

Schematic. Separating tools gives the API a clear role; it does not remove the need to test errors and permissions.

Code export

Export can mean a deployable frontend, backend source tied to a runtime, or a data backup. These are different migration options.

WeWeb: Supports code export and self-hosting. Check the current plan and the services used by your exported app.
Xano: Its CLI can push and pull a workspace as XanoScript. Those files describe a Xano backend; they are not a standalone replacement for the platform runtime.
Bubble: Its ownership documentation says moving off the platform requires rebuilding the application logic. Data export is a separate capability.

Back-end performance

Xano offers better performance potential for those who know how to optimize it; Bubble is simpler but less flexible for high-load optimization.

Xano: Provides tools like database indexes and response caching to keep queries fast, even with huge amounts of data or heavy user load.
Bubble: Handles queries “out of the box”. While not necessarily slow, it lacks advanced optimization tools and proper caching mechanisms for ultra low-latency pages.

Security

Bubble has excellent built-in privacy rules; Xano has more enterprise-level certifications.

Xano: Its Trust Center lists SOC 2 Type II and ISO certifications, alongside separate GDPR and HIPAA attestations. These cover the platform; your team still needs to implement application access rules.
Bubble: Its security documentation describes SOC 2 Type II compliance and shared responsibility for application security. Privacy Rules let you configure access to records and fields; the application still needs correct rules and lawful data handling.

Community and marketplace

Bubble has the largest community and marketplace; WeWeb and Xano are growing but smaller.

WeWeb: Its marketplace offers templates and libraries. Check whether a reusable asset covers the specific feature you need.
Xano: Has a snippet marketplace, though searching/discovery is currently limited.
Bubble: Large community and thousands of plugins. This makes finding solutions and fellow developers much easier.

Compare the same product in both setups

Build a representative screen and workflow
Test the database queries your app needs
Check permissions for every user role
Include hosting, plugins and maintenance in the comparison

A practical review of the areas discussed above, before comparing subscription plans.

Pricing

Compare the cost of the same application

Representative flow One screen and its data operations
Expected usage Users, requests and stored data
Operating cost Plans, plugins and maintenance
Team decision Cost and ability to support it

Subscriptions are one part of the comparison. Use the same expected workload and maintenance requirements for both options.

Compare the current plans against your expected usage, hosting needs and required features.

WeWeb: Include editor seats, hosting or self-hosting, and any paid assets.
Xano: Include backend capacity and the features your endpoints need.
Bubble: Include workload consumption, plugins and the required hosting plan.

Use the current WeWeb, Xano and Bubble price lists for the final calculation.

Choosing for your team

Both approaches have their place. Bubble suits builders who want the frontend and backend in one tool. WeWeb + Xano is better suited for complex projects requiring detailed control over performance and functionality.

Our original reason for pairing WeWeb with Xano was to control the interface and backend separately. For your project, the decision should follow the requirements and the team that will maintain it.
