This article compares Retool and Bubble, two well-known low-code app development platforms, examining their use cases, applications, and limitations to help you make an informed decision. We will evaluate the two based on ease of use, integrations, scalability, and more.
Both Retool and Bubble are considered low-code platforms that allow you to build various kinds of apps. Right from the start, the most notable difference lies in the types of apps that can realistically be built in Retool versus Bubble. Both platforms can be used to create simple internal apps like dashboards, forms, surveys, and data collection tools. However, they diverge when it comes to building enterprise-grade, robust internal tools that are scalable and typically required by more mature startups or companies. Retool excels in this use case, whereas Bubble faces limitations, such as relying on integrations through plugins.
On the other hand, Bubble is particularly strong in building responsive websites, landing pages, marketplaces, listings, and portals. While these can technically be built in Retool, it doesn’t offer the same flexibility needed for some client-facing apps. Both tools are also commonly used for rapid prototyping, but they cater to different user categories: Retool is favored by developers, while Bubble is used by citizen developers or dedicated Bubble developers, who are often found on platforms like LinkedIn or Upwork.
Internal Tools
Retool takes the cake here, as it has been focused on this use case (until recently, when they introduced Retool for external users) and has developed robust functionality to meet all potential requirements. It natively integrates with virtually any backend, ensuring scalability. In contrast, Bubble integrates through plugins, which often raise compatibility, stability, and scalability concerns for companies building mission-critical internal tools. Looking at the top templates on the Retool vs. Bubble websites, we can clearly see a distinction: tools like marketplaces and project management apps dominate the list for Bubble, while Retool's top templates include apps like MongoDB Dashboards and Firebase Admin Panels.
Native integrations with Databases and APIs
Ease of use for Developers
Version control, including Git
Massive library of plugins
Client Portals
Client portals enable multi-tenancy or secure access to the app for external users, ensuring they can only view their own data. For instance, when a client logs into an agency portal, they will see only their projects and tasks, not those of other clients. Retool recently introduced a dedicated solution for portals, offering pricing better suited for larger volumes of external users, along with features like branding and email customization. However, Bubble is better suited for portals, as it provides greater flexibility in UI customization, which is essential for externally-facing apps.
Could be easier to operate for developers
Better UI look-and-feel
Pricing scales better with external user growth
Websites
One can build websites for their startup, marketplaces, and other public-access apps in Bubble, while Retool doesn’t have this option at all.
Mobile apps
Both apps have a web-focused history and, for a long time, could only provide responsiveness for mobile apps. However, at the beginning of 2024, Retool launched a native mobile builder, followed by Bubble’s release of a similar builder at the end of 2024 (currently in beta). Despite being in beta, Bubble's native mobile builder is likely the better option due to its more polished UI and superior “look-and-feel” customization options, which are critical for most mobile apps.

Better-looking UI
PWAs
PWAs, or Progressive Web Apps, cannot be built for the most part in Retool. Although some common functionalities of PWAs, such as push notifications, can be implemented in Retool’s native apps, Retool is generally not suited for PWAs, while Bubble is.
The builders - how technical should they be?
To start building in Bubble, programming knowledge is not required, but you will need to learn its "internal language" along with the rules and guidelines specific to building in Bubble. While it shares some similarities with traditional development, expertise in front-end or back-end development won’t significantly reduce the learning curve. On the other hand, developers typically find building in Retool quite intuitive, as it was specifically designed for developers.
Internal and External users pricing
Retool uses a user-based pricing model, where the price is set per user and depends on the pricing tier. Different user roles are priced differently: internal builders/editors start at $12 per month, internal end users (e.g., customer success managers interacting with a dashboard) start at $7 per month, and external users (e.g., vendors in a client portal) have a fixed price of $8 per month.
Bubble, on the other hand, has usage-based pricing. It calculates the "resource" required to perform a unit of work (measured in workload units) and charges accordingly. The cost varies based on the type of app and how extensively it is used. Bubble’s pricing tiers include a specific amount of workload units, starting at $32 per month. In addition to this, it’s important to consider the potential costs of purchasing plugins, which can be difficult to estimate when you’re just starting with your app.

Agency plans
Bubble also offers an Agency plan, designed for agencies or freelancers building in Bubble for their clients, with a fixed price of $85 per month. Previously, Bubble charged extra for additional apps, but now both platforms allow users to build as many apps as they’d like without incurring additional charges for extra apps. Retool, while not offering a separate pricing plan for partners, has a partner program that requires an application.

Learning curve and ease of use
Developers typically find their way around Retool fairly easily, as many aspects of its building mechanics are similar to programming languages. For instance, to bind two components, you simply open curly braces and write JavaScript, which feels quite intuitive. Once you familiarize yourself with the basics and have JavaScript experience, building in Retool becomes relatively straightforward.Bubble, on the other hand, is strictly a no-code tool but has a steep learning curve, comparable to platforms like Webflow or Figma. It has many nuances, and some individuals even build careers around learning how to create tools for clients in Bubble. Reports suggest that it can take anywhere from a few months to a couple of years to fully learn and master Bubble.

How easy it is to upscale the app?
Retool provides a more robust toolkit for scaling applications. For example, if you are transitioning from MySQL to Snowflake as your primary data source, although some adjustments may be required, the process is generally straightforward. The same applies if your company grows and needs to transition to a private cloud or local hosting—Retool has the infrastructure to support such needs.
In contrast, Bubble does not scale as effectively when backend infrastructure expands. Its approach of combining the front-end and back-end within a single tool can create significant friction points as systems grow. Another limitation of Bubble is that it only supports JavaScript for building custom components. While JavaScript is widely used, Retool also allows you to extend your app using React and Vue, providing additional flexibility.

Permission management
Both Retool and Bubble provide granular permission management at the component and data levels. In both tools, admins can configure permissions to restrict users from accessing certain apps, workflows, or connected resources. The key difference lies in how this is implemented: in Retool, permissions are managed using JavaScript, while in Bubble, it is done through a no-code point-and-click interface.

Multi-tenancy
Retool provides built-in functionality to reference variables in visibility or filtering rules, allowing for the separation of data for different users (tenants). This enables granular control over which UI elements and data specific users or groups of users can see and interact with.In Bubble, you can control the visibility of information for specific users out of the box by assigning a type to each user at login (commonly using an Option Set on the Users table). Based on this user type, you can display the appropriate pages (for a multi-page app) or groups (for a dashboard). While it is possible to create multi-tenant apps in Bubble, doing so requires significantly more effort and time compared to Retool.
Easy to set for technical users
No-code approach to enabling multi-tenancy
Retool provides a library of built-in components, such as tables, lists, forms, and buttons, with a total of more than 100 components. Bubble takes a more lower-level, granular approach, not offering some popular elements out of the box. For instance, a form component is included in Retool's component library and can be drag-and-dropped as a complete unit. In contrast, in Bubble, you would need to drop individual input fields onto the canvas and manually link them together. While this approach offers greater flexibility, it can complicate the building process for simple use cases where pre-built components would suffice.
Templates
Both Retool and Bubble offer a library of templates to help users get started quickly. However, with Bubble, this is handled through an external marketplace where third-party vendors build and sell templates. This approach has its advantages, as the ecosystem of plugins and templates is much larger. However, it also comes with the downside of relying on community builders, which introduces potential risks such as inconsistent quality or limited support.
More than 300 templates in the library

Both Retool and Bubble provide the option to code your own custom components and embed them into the app. Retool provides a greater extendability due to larger variety of frameworks one can use to build custom components: React, HTML, Java Script.
Custom components
Both Retool and Bubble provide the option to code your own custom components. However, in Bubble, this can only be done using JavaScript, and the functionality is limited to being used within Bubble itself. In contrast, Retool allows you to code custom UI components in nearly any front-end language and embed them into the app, offering greater flexibility and broader compatibility.

Pixel-Perfect apps
To put it simply, pixel-perfect design is not achievable in Retool or Bubble using standard capabilities. While it is possible to code fully custom components to achieve a perfect UI, doing so undermines the purpose of using no-code/low-code platforms. Bubble does provide Figma import but has several limitations. If your focus is perfect on-brand design and ease of use, you might want to consider tools like Jet Admin, which offer features such as direct Figma import and easy front-end logic integration.

Themes
Retool’s theme builder allows users to adjust elements such as background colors, UI element surface colors, text colors, typography, and more. It provides a convenient way to set and manage themes across apps, ensuring consistency.Bubble, on the other hand, takes a more "design-centered" approach to themes, where themes are essentially a collection of styles. This approach offers more flexibility and is better suited for users with a design background. Retool prioritizes simplicity in theming, which comes at the expense of some flexibility.

Branding
Both Retool and Bubble enable the creation of branded apps for both internal and external users. Retool offers branding options across several user journey touchpoints, including email invitations, transactional emails, login and sign-up pages, the main menu, and individual apps. It relies on its internal theme builder for custom branding, which, while user-friendly, comes with some limitations.
Bubble, with its strong focus on design, leans heavily on external style and visual asset imports. This approach provides exceptional flexibility, allowing users to create truly on-brand experiences that can be tailored to meet even the most specific branding requirements.

Unlike Bubble, Retool allows you to separate your backend logic from the frontend. For example, you can create a logic layer in Xano and connect it to Retool’s UI, which is a common use case. Retool offers a wide range of native integrations, enabling you to connect your app to almost any backend you might be using.
Bubble, on the other hand, comes with a built-in backend that is used by default. While this simplifies setup, it can pose challenges for users who require full control over their data model. However, Bubble's backend can be extended through third-party plugins, providing additional flexibility for more advanced use cases.
Integrations
Bubble has an extensive library of plugins that allow it to integrate with virtually anything. However, it lacks native integrations, which can be a challenge when scaling the backend of an app. On the other hand, unlike Retool, Bubble offers numerous integrations with analytical tools such as Google Analytics and Mixpanel, providing valuable support for scaling and growing apps built with Bubble.
Bubble includes a built-in database by default, whereas Retool offers it as an optional feature alongside external database integrations, giving users more flexibility in choosing their data sources.
The same distinction applies to APIs: Retool supports popular standards like REST, GraphQL, and gRPC out of the box. In contrast, Bubble requires configuring a specific "connector" to interact with external APIs, which must be set up according to Bubble’s documentation rather than relying on widely accepted standards.

Automation (Workflows & Logic)
The front-end logic layer in Retool is built on JavaScript, offering almost unlimited scripting capabilities, with a few exceptions, such as tracking drag-and-drop components or similar niche use cases. Retool also includes a workflow builder that provides an automation layer, enabling users to create a sequence of actions like data transformations, external API calls, or utilizing built-in functions such as fetching the current time.
Bubble also features a workflow builder, which, as expected, allows you to build logic without needing to write JavaScript. However, the UI of Bubble's builder is somewhat outdated and can be challenging to navigate, especially when working with multi-branch workflows or generally complex logic structures.

Logic and conditionals
Retool uses JavaScript as the primary method for front-end scripting. JavaScript can be written almost anywhere in Retool, enabling users to dynamically set property values using transformations or conditional logic. These configured logic pieces can be utilized for tasks such as complex filtering, referencing, or controlling the dynamic visibility of components.
Bubble, on the other hand, provides an abstraction layer for building logic without writing code. In addition to workflows, Bubble features "Dynamic Expressions," which are used to construct logical "sentences" that calculate values, set conditions, perform database searches, or call external APIs.
Java Script can be used almost anywhere in the app

Data editing
Both Retool and Bubble include a built-in database editor that provides easy access to an internal database. These editors allow users to search, filter, and edit data directly within the platform.

External API
Retool offers the ability to extend the app externally through an API, supporting standard methods like GET, POST, PATCH, and DELETE for managing users, user attributes, permissions, resources, environments, and more. This provides great flexibility for integrating and scaling applications. Bubble, at present, does not offer this option
Deployment
Bubble only provides cloud hosting, while Retool provides both cloud and self-hosted options. Retool also provides a Deployment Dashboard to view the status of deployments, logs, and manually deploy changes.

Releases & version control
Bubble, similar to Retool, provides most of the basic release control functionality, including custom branches, multiple savepoints, and history. However, Bubble offers only two environments—Development and Live—that cannot be deleted, with each having a separate database. Additionally, Bubble lacks Git integration, which Retool supports. Git integration allows Retool apps to connect with repositories like GitHub, GitLab, and AWS CodeCommit, offering a seamless and efficient experience for developers.

Security and Data Privacy
Retool provides a high level of security and data privacy with features such as a self-hosted deployment option, encryption, role-based controls, multi-factor authentication, OAuth and SAML support, and IP whitelisting. Retool is also SOC 2 certified and compliant with GDPR and HIPAA. In contrast, Bubble does not offer a self-hosted deployment option or support for IP whitelisting. Additionally, Bubble's heavy reliance on third-party plugins introduces significant security risks.

Source Code export
Both Retool and Bubble retain ownership of the code and, to an extent, the app you’ve built on their platforms. The key difference, however, is that not owning the code for an internal tool, such as a dashboard, is generally more acceptable than not owning the code for your main app that customers interact with. This introduces a range of risks when starting development on Bubble. If you decide to move away from either Bubble or Retool at any point, the process will be equally painful and costly.

Jet Admin - flexibility and usability sweet spot
Jet Admin was designed with a strong focus on apps involving external users, such as client and vendor portals, category management apps, and more. Unlike Retool, its pricing scales well for a large number of users and supports many simple to mid-complexity use cases without requiring code, enabling non-technical or semi-technical users to build apps quickly.
Compared to Bubble, Jet Admin emphasizes native integrations and back-end flexibility while offering intuitive building mechanics. Variable referencing, calculations, conditional logic, workflows, data blending, and data transformations are handled through a point-and-click UI, with the option to extend the app using custom components and JavaScript front-end scripting. Components like forms and tables are automatically generated based on the schema of your data source, and CRUD functions can be reused throughout the app.
