Windows 11's built-in Weather app wastes more than 1 GB of RAM

Key Themes from the discussion

Theme Summary Representative Quote
1. RAM usage is excessive Many commenters say a weather widget should comfortably fit in far less than 100 MB, calling 1 GB “overkill.” “A well thought-out, native Weather app wouldn't take more than 100 mb of RAM.” — iamcoder18
2. Simpler, lightweight alternatives exist Users point to tiny native or command‑line tools that work with only a few megabytes (or less). “Back in my day a weather app took 10 MB and I was complaining (1999).” — blackhaz
3. Framework bloat drives memory consumption The app is built on WebView2/Chromium, spawning separate processes that appear as separate RAM usage, inflating the apparent cost. “Looks like about 30 MiB with a quick test.” — Throwthrowbob (showing a much smaller footprint when isolated)
4. Business/advertising incentives add bloat Several remarks link the size to corporate metrics, ads, or the need to juice KPIs rather than engineering efficiency. “What’s next? Ads on the start menu?” — mort96

These four themes capture the dominant talking points: the perception of excessive memory use, the existence of far leaner solutions, the role of heavy frameworks (WebView/Electron) in inflating that use, and the organizational pressures that encourage bloated implementations.

WeatherLite Native Widget

Summary

  • Provides a native Windows weather widget that runs in under 10 MB RAM, tackling the RAM‑bloat complaints.
  • Core value: ultra‑lightweight, ad‑free weather info with instant UI responsiveness.

Details

Key Value
Target Audience Windows 10/11 power users and minimalists who monitor weather from the desktop
Core Feature Real‑time local weather and radar via wttr.in API, optional 3‑day forecast, system‑tray icon with click‑to‑expand
Tech Stack C/C++, Win32 API, winhttp, static linking, optional DirectWrite for rendering
Difficulty Medium
Monetization Hobby

Notes

  • HN commenters repeatedly lament 100‑300 MB RAM usage; this delivers the same features in a few MB, matching the “back‑in‑my‑day” efficiency they yearn for.
  • Could spark discussion about reviving native code for simple utilities and serve as a reference implementation for other devs.

SharedWebView2 Runtime for Windows Widgets

Summary

  • Offers a background WebView2 service that hosts a single Chromium instance shared across all widget apps, cutting per‑app RAM overhead.
  • Core value: Multi‑app memory efficiency while retaining web‑based UI flexibility.

Details

Key Value
Target Audience Developers of Windows widget‑style apps (weather, news, finance) using WebView2 today
Core Feature Centralized WebView2 process exposing a lightweight API for widgets to request data and render UI without launching separate browsers
Tech Stack C#, .NET 8, WebView2 runtime, Windows Service, inter‑process communication via named pipes
Difficulty High
Monetization Hobby

Notes

  • Users complain that each widget spawns its own Chromium process, wasting GBs of memory; a shared runtime would reclaim that waste and align with HN's desire for leaner defaults.
  • Sparks conversation about OS‑level compositing of web‑based UI components and could be extended to other Microsoft‑provided web‑based services.

RetroWeather CLI & Cache Daemon

Summary

  • Delivers a command‑line weather client with on‑disk caching that persists forecasts for 12 hours, enabling scriptable use without network overhead.
  • Core value: Near‑zero memory footprint and usable in automation pipelines.

Details

Key Value
Target Audience Scriptwriters, sysadmins, and CLI lovers who need quick weather checks in batch jobs
Core Feature Queries wttr.in, stores JSON response in ~/.cache/weather.json, provides colored TUI or plain output; supports location via IP or CLI flag
Tech Stack Rust, serde, prettytable-rs, chrono, file I/O
Difficulty Low
Monetization Hobby

Notes

  • HN participants reference “back‑in‑my‑day” tiny utilities; a CLI that fits on a floppy (~200 KB) would resonate with that nostalgia while still offering modern data.
  • Generates discussion about reviving simple command‑line tools as an antidote to heavyweight Electron apps.

Lightweight Browser Weather Extension

Summary

  • A tiny browser extension that injects a minimalist weather widget into any page using only CSS and a small JavaScript fetch, staying under 5 MB.
  • Core value: Instant weather glance without opening a separate app, with negligible impact on page memory.

Details

Key Value
Target Audience Web users who want weather info while browsing, especially on low‑spec machines
Core Feature Adds a collapsible weather card to the toolbar, pulls data from Open‑Meteo, caches for 6 hours, styles with CSS variables
Tech Stack JavaScript (ES6), WebExtension API, HTML/CSS, Open‑Meteo API
Difficulty Low
Monetization Hobby

Notes

  • Commenters stress that even a simple widget can balloon to 100 MB when built on heavy frameworks; this extension proves a <5 MB solution is feasible.
  • Encourages dialogue on “web‑first” UI design that respects user resources and can be packaged as an add‑on for Edge/Firefox.
