This has created a massive and growing category of ephemeral Web applications that need to be shared and used immediately across devices and platforms, without a traditional server for distribution, without association with a Web origin, and without being confined to a web browser.<\/p>\n\n<p>No existing format treats interactive web content as a portable, self-contained, immediately runnable unit. PDF loses interactivity. EPUB3 is constrained to a document and book model \u2014 its JavaScript support is an enhancement to a reading experience, not a general-purpose runtime. Web Bundles never achieved broad implementation and was designed as a network transport optimization, not a portable execution environment. The Web Application Manifest describes server-hosted apps and requires a live web origin. None of these addresses the need for content that has no server, no origin, and no installation \u2014content that should exist, run, and be shared as a single portable file, across all platforms, entirely offline.<\/p>\n\n<p>This mission of this group is to develop an open specification for a self-contained portable web content format that can be instantly shared and run on any platform \u2014desktop, mobile, or offline\u2014 without a server, app store, or deployment pipeline. The format is content-model agnostic, equally supporting books, games, presentations, educational simulations, 3D experiences, scientific models, and collaborative applications.<\/p>\n\n<p>The scope of work includes:<\/p>\n\n<ul>\n<li>Container and packaging format<\/li>\n<li>Manifest schema for capability and permission declaration<\/li>\n<li>Viewer conformance requirements and security sandboxing model<\/li>\n<li>Storage model \u2014per-bundle isolated storage specification, defining how packaged content can persist state locally, how storage is scoped and sandboxed to the bundle, and guidelines for storage portability across viewer implementations.<\/li>\n<li>Inter-bundle communication model \u2014 a permission-gated channel specification enabling bundles to communicate locally via Bluetooth, WiFi Direct, or local network, making offline multiplayer, peer-to-peer, and collaborative interactive experiences possible without any server infrastructure. This is a genuinely novel capability not addressed by any existing format or specification.<\/li>\n<\/ul>\n\n<p>In addition to a Specification, this group expects to create a Viewer conformance test suite, and a non-normative implementation guide for content creators, AI tools, and viewer developers.<\/p>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-dots\"\/>\n\n\n<p class=\"wp-block-paragraph\">\n    You are invited to <a href=\"https:\/\/www.w3.org\/community\/groups\/proposed\/#portableweb\">support the creation of this group<\/a>.\n    Once the group has a total of 5 supporters, it will be launched and people can join to begin work.
