Why Toolpad?

Learn how Toolpad approaches building internal tools, and how it can be useful to you.


  • Higher-level API. Toolpad operates at a higher abstraction level than Material UI. It sets healthy UI constraints that prevent common pitfalls and anti-patterns.
  • Drag-and-drop builder. Toolpad comes with a drag-and-drop builder to simplify UI building. The builder saves the UI as a YAML file, so you can even modify and version the visual output on your file system.
  • Less boilerplate so you can focus on the essential parts of the app.
  • Run alongside existing code. Toolpad integrates well with your existing code. You can use your database models, client libraries, secrets, and bespoke components directly.
  • Single source of truth. Because Toolpad runs alongside your existing code, it lets you maintain a single source of truth for all business logic.
  • Integrates well with your development lifecycle. Your project lives on your file system. You can use your own IDE, version control system, deployment target, CLI tools.

Trade-offs with pro-code tools

The key problems most pro-code tools have relative to Toolpad:

Slower delivery speed

Every organization wants to achieve fast delivery but in order to accommodate various use cases, you are pushed to choose flexible pro-code solutions.

This flexibility comes at the cost of more boilerplate code. To connect backend data to the browser and set up data-display components, a substantial amount of boilerplate HTML, CSS, and JavaScript glue code is often required. As the use cases repeat themselves, you create abstractions but their maintenance burden quickly grows.

Wouldn't it be great if you could use a tool that abstracts the repetitive parts of creating internal tools?

No direct manipulation of objects

By the definition of a pro-code tool, you write code in an IDE and the UI renders in the browser, a different window.

You can't directly manipulate the parameters, queries, etc. in the browser. It makes it harder to make changes on the application.

Wouldn't it be great if it was possible to directly manipulate the app created in the browser, manipulating the data the closest possible to the source of truth?

Require specialized knowledge

Creating internal tools with pro-code requires knowledge of front-end technologies.

While front-end developers feel comfortable with it, most developers of internal tools are full-stack engineers, people who consider writing low-level CSS and React code a distraction.

Wouldn't it be great if you could use a tool that is approachable, not requiring to be a React expert?

Trade-offs with low-code tools

The key problems most low-code tools have relative to Toolpad:


Low-code tools can be hard to extend. When the tool can't handle a particular task by default, integrating your own code seamlessly is often a challenge.

This lack of flexibility often results in being stuck or having to write custom code inside these apps and storing the business logic within their configuration files.

Would it be great if the tool would use code in your filesystem as the source of truth?

Duplication of logic

When working with low-code or no-code tools, the duplication of code and logic can frequently occur because of a lack of extensibility. Developers invest valuable time in hunting down specific versions of business logic and maintaining them in multiple places.

This lack of a unified reference point within the codebase can compromise its scalability, making maintenance and debugging more challenging.

Cheaper developer tooling

When developers use low-code or no-code tools, they frequently sacrifice their autonomy and become restricted by the options provided by the tool. The introduction of a black-box element prevents access to the high-quality tools developers are used to when working with pro-code, e.g. Git for version control.

This can lead to a significant problem when it comes to the long-term maintainability of internal tools, as it becomes challenging to adapt, extend, or customize them to meet evolving needs.

How Toolpad fits in

Addressing the problems mentioned above leads to a better developer experience. Toolpad solves them in the following ways:

How Toolpad fits in your codebase

How Toolpad fits in your workflow

Drag-and-drop builder

Toolpad works as a drag-and-drop UI builder and uses MUI's own Material UI components. Material UI includes all of the foundational components required for internal use cases. Toolpad currently supports 16 of them, and we're continuously adding more.

Toolpad supports adding any number of custom React components for other use cases. The drag-and-drop builder enables you to quickly assemble a minimum viable UI that's endlessly customizable, ensuring the best of both worlds: speed and flexibility.

Single source of truth

Toolpad offers two ways to connect to your data, ensuring that you can keep your data in one centralized location and avoid duplicating it for each internal tool you create:

  1. Link REST APIs to Toolpad through HTTP queries: This common method allows you to access your data directly by building REST queries in a visual interface.
  2. Write custom functions in your own IDE to connect to any data source: You can use your existing scripts, business logic, database models, client libraries, and secrets. This approach helps you maintain a single, shared data source for all your internal tools, preventing data duplication and ensuring consistency across applications.

Integrates with your development lifecycle

Toolpad empowers you with total control over the entire development lifecycle of your application. It operates on a "local-first" principle, where your project resides on your local file system. This enables you to utilize your preferred Integrated Development Environment (IDE), version control system, deployment target, and Command Line Interface (CLI) tools.

Similar to any Node.js application, you have the flexibility to self-host a Toolpad app on your own server or select a hosting provider that suits your needs, whether it's AWS, Render, Railway, or Heroku. Toolpad does not confine you to its cloud hosting, ensuring you have the freedom to choose the hosting solution that best aligns with your preferences and requirements.

Like any Node.js app, you can self-host a Toolpad app on your own server or any hosting provider of your choice (such as AWS, Render, Railway, or Heroku). Toolpad does not lock you into its cloud hosting.

Seamless collaboration

The Toolpad application configuration is saved in YAML files, which can be conveniently added to Git or any preferred version control tool for collaborative maintenance. Maintaining a private code repository is a fundamental practice for enhancing the security of user data. This eliminates the need to create new collaboration mechanisms for engineers, as the existing tools can be effectively leveraged.

Trust and safety

While organizations make every effort to protect highly sensitive data and conduct thorough vendor due diligence and compliance assessments, data breaches continue to be a significant concern. Toolpad ensures that you can maintain control over your data, helping to address this issue.
