Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

AvaloniaUI: Create Multi-Platform Apps with .NET
- https://gitlab.com/sciter-engine/sciter-js-sdk/-/tree/main/b... - Skia backend.
You can load in usciter this document:
https://gitlab.com/sciter-engine/sciter-js-sdk/-/blob/main/s...
It shows pretty large colorized texts so you can estimate how Direct2D and Skia handle GPU accelerated text rendering. For these two binaries the difference is only in graphics used - Direct2D and Skia.

Show HN: DataSheetGrid, an Airtable-like React component
Agree about virtualization in principle. Not that nightmarish though.
My Sciter supports built-in virtualization out of the box. But I shall admit that this is second approach to the problem.
Currently Sciter's behavior:virtual-list supports as fixed-height items (that's easy) as variable-height items like messages [1] in chats.
API is relatively simple [2]: single event "contentrequired" that virtual-list sends to JS. In response JS shall either append or prepend requested number of DOM elements to the container (a.k.a. sliding window scroller). Example, grid showing 20000 records: https://gitlab.com/sciter-engine/sciter-js-sdk/-/blob/main/s...

I've built a multi-session browser
Thank you for your explanation. As for Electron alternatives, Sciter is much more lightweight, supports Vue and includes a native webview. Anyway, good luck with your project!
- JavaScript import maps are now supported cross-browser

XUL Layout has been removed from Firefox
> we have a number of other libs to integrate, some of which add their own rendering (which requires access to e.g. a Vulkan context, not merely HTML/CSS or other high-level UI elements)…
I have a customer that is doing something close: it is a 3D CAD alike app where they have Vulkan rendering 3D scene with Sciter UI on top of that - rendering chrome UI around that 3D and on the same Vulkan surface.
Sciter API supports rendering in windowless mode (https://gitlab.com/sciter-engine/sciter-js-sdk/-/tree/main/d...) where app supplies OpenGL, Vulkan or DirectX context to render on.
> Sorry, but I'll have to pass.
Understood. Sometimes people need not just to get job done but also "OS" label on it.

Flutter Desktop Isn't There Yet
Attempt to combine all these definition in single language is doomed to fail. If in doubts then look at WPF.
3. Notes on language-behind-UI...
If to consider #2 then such simple thing as JavaScript language and VM are quite adequate to the task. Language-behind-UI do not need to be that performant, but it must be flexible. I may express un-popular opinion but language-behind-UI should be typeless.
Simply put: don't do ray tracing in language-behind-UI. But! Such a language shall have simple mechanism of adding high performant functions. There are good languages that are specifically designed for performance: C, C++, D, Rust, Zig, WebAssembly, etc. You just need convenient mechanism to expose those functions to runtime of language-behind-UI. Like here: https://gitlab.com/sciter-engine/sciter-js-sdk/-/blob/main/d...
You need JITs, compilation, fat VMs and runtimes, strong types only if your language is the only mean to define algorithms in whole application. But expect that your code will always be sub-optimal - neither enough performant nor super flexible.
4. Conclusion
Flutter should be something Sciter-alike :) - use [X]HTML/JSX, CSS and some already well known language-behind-UI. JavaScript is the natural choice. If needed you should be able to use native UI components - like in Sciter you can use existing HWND based and windowless native components inside your UI. It may not follow Web UI model on 100% (that's impossible) but to be conceptually close so developers can reuse their skills. Web UI model is conceptually close to Mobile one - all application UI is constrained inside single window.

What is the fastest, lightest weight GUI framework?
I'm surprised no one has mentioned it but I've been using SciterJS (website) for my most recent project. I wouldn't ever claim it's the best UI framework out there, but it's lightweight and I've never felt so productive - I've rapidly developed my UI and integrated it with my native C++ far faster than I thought possible. I will note that it is far, far cheaper and has so many more features than Ultralight does.

The miracle of Smalltalk’s become: (2009)
Only when code tries to access props/methods of the loaded object it gets fetched from disk, its __proto__ is set to particular class, etc.

Patched QuickJS with storage support is here: https://gitlab.com/c-smile/quickjspp - it uses DyBase of Konstantin Knizhnik as a storage.

The Design Philosophy of Great Tables (Software Package)
Why do you want to render to canvas?
Perspective seems to be the most performant html table. It is more focused on extremely fast updates than styling, although it looks good.
Glide is a newcomer that also renders to canvas.

SQL workbench also uses https://perspective.finos.org/ for tables. It's a WASM table library which pairs nicely with duckdb and works well with large tables.

Show HN: DataSheetGrid, an Airtable-like React component
I haven't looked extensively at react-datasheet. It looks like it is trying to build more of a full product than the other data tables.
I have used ag-grid extensively, its an impressive product. Some pieces are a little awkward to use, particularly auto-sizing. But generally ag-grid has thought of most functionality and has a solution. The creator of ag-grid had a great interview on Javascript Jabber [1].
The other serious data table component that I have seen is FinOS Perspective [2]. This is extremely high performance, also more specialized and probably harder to customize. I think Perspective renders to a canvas element from Rust/C++ compiled to WASM (not 100% sure). It is also made for streaming updates.
AG-Grid supports streaming updates... but only in the commercial version.
Eventually the data model for these types of tables becomes tricky. I will be investigating parquet-wasm for my use case. Hit me up if you want to collaborate.

ChDB: Embedded OLAP SQL Engine Powered by ClickHouse
Something like https://github.com/finos/perspective ? We use an OLAP(-y) WASM engine to provide query-ability to our data visualization tool, and doing the calculations in the browser is cheaper and simpler than a server-side database for datasets that fit in browser memory.
