DESCRIPTION:https://www.w3.org/events/meetings/47c8159d-9fea-4778-9b04-bd28
 a479a7c2/\n\nThis session will explore how to **diversify the ecosystem of
  Web user agents by enabling profile applications** to increase efficiency
  and optimize user experience on Web and WebView-based apps while maintain
 ing compatibility with existing standards and the **One-Web** principle. \
 n\n#### Background\n\nIn early January\, W3C organized the [WebAI and High
 -Performance Web Application Technology seminar](https://www.w3.org/2024/0
 1/webevolve-series-events/ai-and-highperf/zh.index.html) for the Chinese c
 ommunity. One of the outcomes of the discussions was the launch of a new C
 G to support more variety and more performant Web user agents. \n\nThe CG 
 aims to diversify the **ecosystem of Web user agents** by enabling **profi
 le standards to increase efficiency and optimize user experience** on Web 
 and WebView-based apps while maintaining compatibility with existing stand
 ards. Standard profiles and modularity might ease the design and implement
 ation of lighter and more efficient engines for specific-scenario purposes
  when a full-fledged (embedded) browser is not required (e.g.\, MiniApps\,
  WoT edge apps\, and apps for wearables or constrained infotainment system
 s) and may serve as common ground for cross-platform development framework
 s. \n\nPackage distribution strategies should be considered in conjunction
  with profile standards to ensure optimal content presentation across dive
 rse platforms. Profile standards should be built with mobile-friendly feat
 ures by default\, ensuring a superior user experience and leveraging the u
 nique capabilities of mobile devices.\n\nThe CG was titled _High-Performan
 ce Baseline for Web Apps_ as a placeholder\, but we know it could be misle
 ading -also the initial description. In this breakout session\, we would l
 ike to clarify the objectives and get the community's feedback to include 
 these insights in the final chapter. The title\, scope\, and objectives wi
 ll be discussed in this session.\n\n#### Audience\n\nThis session welcomes
  vendors of embedded browsers\, hybrid cross-platform app frameworks\, JS 
 engines\, and others interested in exploring the modularity of the Web sta
 ndards. We aim to collect use cases where standard profiles help enrich th
 e Web ecosystem by opening new possibilities in unexplored scenarios and s
 upporting innovation on the Web while protecting the principles of **One-W
 eb** and **interoperability**.\n\nWe also want close alignment with other 
 incubation groups working on similar topics (i.e.\, **WebViews CG**\, **W
 ebDX**\,  **WinterTC**) and bi-directional conversations with core standa
 rdization groups for advice and pushing for new standardization requiremen
 ts while avoiding fragmentation. \n\nCheck more information\, including re
 search on [this explainer](https://github.com/espinr/high-perf-apps/blob/m
 ain/explainer.md) and on [this blog post](https://www.w3.org/community/hig
 h-perf-baseline/2025/03/09/a-proposal-for-high-performance-web/).\n\n**Goa

 unity in this new incubation activity.\n\nAgenda\n\n1. Adaptive Web Engine
