React Native Seed features and specs

  • Cross-Platform
    React Native Seed allows developers to create mobile applications that can run on both iOS and Android platforms using a single codebase, reducing development time and resources.
  • Pre-Built Components
    The seed provides a set of pre-built components and scaffolding, which can speed up development by providing a solid structure and reusable UI elements.
  • Community Support
    Being a part of the larger React Native ecosystem, React Native Seed benefits from a vast community of developers who contribute to libraries, tools, and support forums.
  • Customization Flexibility
    Developers can customize the seed to fit their specific project needs, allowing for flexibility in design and functionality while maintaining a structured foundation.
  • Hot Reloading
    React Native Seed supports hot reloading, which enables developers to see updates instantly in the app without losing the application state, improving the development experience.

Possible disadvantages of React Native Seed

  • Performance Limitations
    While optimized for most common use cases, React Native Seed might face performance issues for apps requiring complex animations or heavy computational tasks compared to fully native solutions.
  • Native Module Dependency
    Certain functionality might require native code implementation, meaning developers need knowledge of both JavaScript and the corresponding native languages (Swift/Objective-C for iOS and Java/Kotlin for Android).
  • Limited Out-of-the-Box Features
    While it provides a good starting point, React Native Seed may lack certain advanced features that some complex applications require, necessitating additional development effort.
  • Learning Curve
    Developers not already familiar with React or JavaScript might face a learning curve when starting with React Native Seed.
  • Dependence on Third-Party Libraries
    Many functionalities might rely on third-party libraries, which can lead to compatibility issues or require additional maintenance to keep up-to-date.

Questions and Answers

As answered by people managing React Native Seed and Bryntum.

How would you describe your primary audience?

Bryntum's answer:

Bryntum primarily targets professional software teams - particularly frontend developers, architects, UX, and technical leads who need robust scheduling and project-planning functionality for their web applications. Our products (such as the Scheduler and Gantt components) are designed for organizations that want to integrate sophisticated resource management, timeline visualization, and interactive scheduling into existing or new software solutions.

In practice, these teams often work in industries and use cases where precise scheduling is critical (e.g., project management, construction, healthcare, manufacturing, and IT services). While developers are the day-to-day implementers of Bryntum’s products, managers or product owners (such as PMO leads or development managers) also play a role in evaluating Bryntum’s solutions to ensure they meet the organization’s technical and business requirements.

What makes your product unique?

Bryntum's answer:

What Makes Bryntum Unique?

Bryntum stands out because of its laser focus on high-performance, enterprise-grade JavaScript components—particularly around scheduling and project planning. Here are a few reasons why Bryntum is unique:

  1. Advanced Scheduling Expertise
    Bryntum’s Scheduler and Gantt products are widely recognized for their sophisticated scheduling capabilities. Their tools handle complex resource allocations, dependencies, drag-and-drop reordering, and timeline visualizations—making them a go-to choice for project and resource management in large-scale applications.

  2. Pure JavaScript (Framework Agnostic)
    All Bryntum components are developed using modern, pure JavaScript. This means they can easily integrate into any tech stack or framework (React, Angular, Vue, etc.) without sacrificing functionality or performance. If you switch frameworks in the future, you can keep using Bryntum’s components with minimal refactoring.

  3. Performance & Scalability
    Bryntum components are designed for high-volume data rendering. Whether it’s thousands of tasks in a Gantt chart or a scheduler loaded with numerous resources, Bryntum’s products can handle heavy data loads smoothly and maintain snappy interactions.

  4. Robust Feature Set
    From critical-path analysis in Gantt charts to resource histograms and timeline overviews, Bryntum packs advanced features that meet enterprise project-planning requirements. This feature depth is one reason many organizations choose Bryntum over more general-purpose grid libraries.

  5. Extensive Documentation & Demos
    Bryntum provides thorough documentation, live examples, and demo apps that showcase how to integrate its components into a variety of environments. This makes it easier for developers to learn the product and quickly build prototypes.

  6. Dedicated Support & Development
    A hallmark of Bryntum is its attentive support. Their engineering and support teams are responsive and highly knowledgeable about both front-end development and project-planning logic, which speeds up troubleshooting and feature requests.

By focusing on scheduling and project-planning tools with high performance, great flexibility, and deep functionality, Bryntum has carved out a niche that sets it apart from other libraries and component vendors.

Why should a person choose your product over its competitors?

Bryntum's answer:

Performance, UX and abundance of features.

Which are the primary technologies used for building your product?

Bryntum's answer:

JavaScript, TypeScript and CSS

What's the story behind your product?

Bryntum's answer:

Bryntum was founded by Mats Bryntse, a software developer from Stockholm, Sweden, who had a deep interest in creating advanced scheduling solutions for web applications. Originally, Bryntum began as a consulting and component-development company centered around Sencha Ext JS, one of the leading JavaScript frameworks in the late 2000s.

Early Days (Ext Scheduler & Gantt)

Mats Bryntse developed the first version of Ext Scheduler, a scheduling component based on Ext JS, in response to a growing demand for an interactive resource-scheduling tool in web applications. Building on the success of Ext Scheduler, Bryntum introduced a Gantt component, allowing developers to visualize and manage project tasks, dependencies, and timelines directly in the browser. Transition to Pure JavaScript

Over time, the JavaScript ecosystem expanded to include many popular frameworks (React, Angular, Vue, etc.). Instead of maintaining separate builds for each, Bryntum decided to make its components framework agnostic, rebuilding them as pure JavaScript libraries. This shift allowed Bryntum’s tools to be integrated into virtually any front-end stack while delivering the same level of performance and scheduling sophistication.

Who are some of the biggest customers of your product?

  • Apple
  • Netflix
  • SpaceX
  • Intel
  • Disney
  • US Navy
  • Airbus
