Preact delivers performance-focused component development without the overhead of traditional frameworks. It is indexed under Frontend UI Frameworks.","source":"https://preactjs.com/","question":"What is Preact?","confidence":0.6},{"answer":"Preact is open source, so it can be self-hosted and used at no licence cost. It is released under the MIT licence. Pricing changes often, so verify at source before relying on it.","source":"https://preactjs.com/","question":"Is Preact free to use?","confidence":0.6},{"answer":"We have confirmed browser-based access to Preact. That is the extent of what we could verify from public sources, so it may well offer desktop or mobile clients we have not indexed.","source":"https://preactjs.com/","question":"What platforms does Preact support?","confidence":0.6},{"answer":"Yes. Preact is published under the MIT licence, a permissive licence that generally allows commercial use and modification. Licence terms can change between releases, so verify against the repository for the version you intend to use.","source":"https://github.com/preactjs/preact","question":"Is Preact open source?","confidence":0.99}]` | `[{"answer":"Vue.js is a JavaScript framework for building user interfaces with a declarative, component-based approach. It enables developers to create reactive web applications that automatically update the DOM when data changes, scaling from simple widgets embedded in existing HTML to complete single-page applications.","source":"https://vuejs.org","question":"What is Vue.js and what is it primarily used for?","confidence":0.95},{"answer":"Yes, Vue.js is entirely open-source and released under the MIT license, which permits free use in both personal and commercial projects. It is maintained by the creator Evan You and the community, with no licensing fees or commercial restrictions.","source":"https://github.com/vuejs/core","question":"Is Vue.js open-source and free to use?","confidence":0.99},{"answer":"No, Vue.js does not require a build step and can be included as a standalone script in HTML to enhance static pages progressively. However, for larger applications using single-file components and advanced features, a build tool like Vite is commonly used to optimize performance and developer experience.","source":"https://vuejs.org/guide/","question":"Do I need a build step or build tools to use Vue.js?","confidence":0.94},{"answer":"Vue 3 is the current maintained version with active support, while Vue 2 reached end-of-life on December 31, 2023.

It also supports progressive enhancement, where Vue can enhance existing HTML without replacing the entire page architecture.","source":"https://vuejs.org/guide/extras/ways-of-using-vue.html","question":"Can Vue.js handle server-side rendering and progressive enhancement?","confidence":0.92}]` |
