Generate your Progressive Web App

ManifoldJS / PWA Builder – Streamlining Web‑to‑App Conversion

ManifoldJS now widely recognized as PWA Builderis an open‑source project initiated by Microsoft to simplify the process of converting a website into a cross‐platform Progressive Web App (PWA) or hosted web app. The core value of the tool lies in its ability to let web developers maintain a single workflow while enabling their site to be packaged as a native installable app across various platforms with minimal friction.

On the homepage, users can input their site URL and employ the platform to automatically generate key components of a PWA: the application manifest, service worker, and PWA assets like icons, along with options for publishing and deployment. This is accessible via both a web interface and a CLI (command‑line interface) that developers can install via npm (e.g., version v2.0.3)

Originally introduced as ManifoldJS, the project allowed developers to package their existing web content as "hosted web apps" which are essentially app store‑installable wrappers around a URL, with updates served dynamically from the web. It standardized around the W3C Web App Manifest to streamline metadata definitions across platforms and used Cordova polyfills where native support was lacking nbellocam.devthishereweb.comMicrosoft for Developers.

In February 2017, the tool was officially rebranded to PWA Builder, reflecting its expanded focus on Progressive Web Apps. The new branding better aligned with its mission to help developers create installable, offline-first web apps using standard open‑web technologies like manifests and service workers. The tool's offerings include helper utilities for manifest generation, icon resizing, service worker scaffolding, platform packaging, and store submission support both via the web UI and CLI Medium.
