Size
Preact is very small in size (about 3KB gzipped), which makes it easy to load and faster to execute, resulting in improved performance and quicker load times.
Compatibility
Preact is largely compatible with React, allowing developers to switch to Preact with minimal code changes. This makes it easier to adopt for projects already using React.
Performance
Due to its small size and efficient design, Preact offers excellent performance, especially on low-powered devices and in applications with heavy user interactions.
Ecosystem
Preact can work with many tools and libraries that are designed for React, giving developers access to a rich ecosystem of resources.
Community
Preact has an active and growing community that provides support, plugins, and third-party tools, making it easier for developers to find solutions and share knowledge.
Preact.js is a strong option for projects where performance and load time are critical, or where a light footprint is necessary. Its compatibility with React makes it a flexible and efficient alternative in scenarios where React may be overkill due to its larger size.
We have collected here some useful links to help you find out if Preact.js is good.
Check the traffic stats of Preact.js on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Preact.js on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Preact.js's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.

> React is a small rendering library Sorry, can't agree. React is a state management library that also attaches efficient rendering on top of the DOM diff it computes as it propagates the state changes. This allows React apps to remain so simple (one function per component) and so composable without turning into an unmanageable dish of callback / future spaghetti. There is a number of other VDOM... - Source: Hacker News / 10 months ago

Note: Astro supports a variety of popular frameworks including React, Preact, Svelte, Vue, SolidJS, AlpineJS and Lit with official integrations.

Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience.

DEV is a Rails monolith, which uses Preact in the front-end using islands architecture.

Preact.js has carved a niche for itself within the ever-evolving landscape of JavaScript frameworks and libraries. Renowned for its lightweight nature and commendable performance, Preact.js is widely celebrated as a more compact alternative to React.js, adopting a similar modern API but at a fraction of the size—just 3Kb. This makes Preact particularly appealing in scenarios where optimal performance is paramount, and resource constraints are tight, such as in mobile or low-bandwidth applications.
Performance and Compatibility
One of Preact’s standout features is its highly optimized virtual DOM, which is touted as the fastest among its peers. This allows developers to leverage the benefits of a virtual DOM with less overhead, making it particularly attractive for high-performance applications. Furthermore, Preact maintains compatibility with React, sharing the component-based architecture and API which allows for a seamless transition between the two and the reuse of React packages without notable performance degradation. This compatibility extends to utilizing React during development and switching to Preact for production to take advantage of its compact size. Such versatility is recognized by major industry players such as Tencent, Uber, and Lyft, who have integrated Preact into their workflows.
Usage Considerations and Trends
Despite its advantages, discussions within the developer community suggest a trend of waning interest in Preact. Several publications have noted a slight decline in its adoption, potentially due to the saturation in the market with similar lightweight frameworks such as Inferno and react-lite. However, many in the community still advocate knowing Preact as a valuable skill, especially due to its ease of use in conjunction with broader framework ecosystems like Vue.js, Svelte, and even newer ones like Deno's Fresh—demonstrating Preact’s adaptability.
Preact in Modern Development
In the context of modern development practices, Preact's compatibility with tools like Vite and its support for frameworks such as SolidJS and Deno Fresh highlight its integration capabilities, making it a sensible choice for developers seeking flexibility with component and state management systems. The library's small size (3-4 kB minified) compared to its contemporaries often makes it a preferred choice for applications where bundle size is crucial.
Community and Ecosystem Involvement
The Preact community is actively engaged in the broader JavaScript ecosystem, with framework developers drawing insights from each other's design principles to maintain interoperability and improve reactivity cores. This collaborative approach ensures that Preact continues to evolve in alignment with next-generation web development standards, thus maintaining its relevance.
In summary, while Preact may not dominate the JavaScript library landscape, its lightweight nature, performance efficiency, and seamless interoperability with React, combined with its integration into modern web tech stacks, make it an enduring and practical choice for developers. It is particularly viable in projects where performance constraints are critical, reaffirming its position as a highly efficient, adaptable, and forward-compatible library.
