Why ID Studio Chooses To Use Svelte

By Neil Kilgallon on Friday, 2 May 2025

Svelte is an open-source JavaScript framework for building web applications. Unlike traditional frameworks like React or Vue, which perform most of their operations in the browser at runtime, Svelte compiles your code into highly optimised, standalone JavaScript at build time. This leads to faster performance and smaller bundle sizes.

While not as established as React, Svelte is rapidly gaining popularity. ID Studio prefers this framework for two main reasons: its simplicity and performance, making it an excellent choice for London’s top web design company when building modern, lightweight websites and apps.

ID Studio’s talented web design team is exploring innovative ways to integrate Svelte into clients’ websites, delivering fast, modern, and cost-effective web solutions.

Short History Of Svelte

Svelte was first released in 2016. Its primary purpose was to address issues with existing JavaScript frameworks, allowing for far superior application development. Since then, five update releases have been made, culminating in the release of version 5 on October 19, 2024.

Svelete is an open-source framework with no costs associated with using its core. Most of its tools are freely available, accompanied by an active and highly sociable support community.

According to data from April 2025, approximately 57,951 to 78,700 websites are currently using Svelte, as reported by BuiltWith and Wappalyzer. The majority of these websites are located in the United States, the United Kingdom, and India. It was voted the 'most loved framework' in Stack Overflow surveys for 2021 and 2022. Svelte has quickly built a solid and growing user base, which continues to expand rapidly.

Reasons Svelte Came About

Svelte emerged from the frustrations that Rich Harris and other developers encountered with JavaScript, which they believed needed simplifying to become more lightweight and efficient, thereby improving performance and reducing browser workloads. Some of the main frustrations and reasons for creating Svelte included:

Heavy bundles and runtime, which slow down applications, were especially true for low-specification devices.
Bloated JavaScript bundles for basic apps, often associated with React and Vue.
Due to the heavy nature of the runtime frameworks, this can cause performance issues, particularly on mobile devices.
Complexity associated with building applications and external libraries, and a significant learning time is required to master skills.
SEO issues where the content was often difficult for search engines to discover.
The number of dependencies that many frameworks require (React over 100). This also brought with it vulnerability risks.
Potential issues with CSS, causing consistency issues.

Some Well-Known Adopters Of Svelte

Below are a few well-known companies that use Svelte:

New York Times

Considering Rich Harris worked at the New York Times, it’s no surprise that they adopted this framework.

Use: For graphics and data sources such as charts and maps.
Impact: Effective storytelling, enhanced performance, and avoided CSS-associated issues that allowed for brand consistency.

Spotify

Spotify required a solution that could handle high volumes and deliver a seamless experience.

Use: Used to provide their listeners with an animated recap of their past listening.
Impact: Ability to deal with high volume usage and drastically improved engagement.

Brave

Brave required a solution that aligns with their commitment to speed and a great user experience. They also needed a solution that would align with their strict privacy values.

Use: Svelte was used to create dynamic elements for the search page.
Impact: Enforced their commitment to an excellent user experience.

Some other well-known companies that have used Svelte include Apple, IBM, Square and Chess.com.

Benefits Of Using Svelte

For this insights article, we will not go into highly technical terminology. We will keep it fairly basic to appeal to a broader audience.

Faster loading pages result from smaller and more efficient coding.
Simplified code makes it easier for users to understand and utilise.
File sizes are reduced, which is excellent for mobile devices or slow connections.
Thanks to the lightweight coding, it loads more quickly in browsers and is less burdensome.
Less code results in quicker build times and lower costs.
Svelte is search engine-friendly.
Automated updates provide smooth changes.

What’s The Catch?

There are not many drawbacks that can be attributed to Svelte. The ones listed below are more like nitpicking and should not detract from the overall quality of Svelte.

Svelte has a smaller community than React. However, it is still highly active and helpful.
It has fewer library items than some of its rivals. This can be viewed as a positive aspect from a security standpoint.
Major updates can sometimes require elements of recoding.
Due to its innovative approach, Svelte will require some training to be used effectively.
Some feedback suggests the compiled code can be more challenging to debug.

Summary

Svelte is a bold, efficient, and impressive front-end framework that provides an excellent solution for building modern websites and applications, with minimal drawbacks.
