pyroscope-rs VS wry

A general purpose profiler: https://github.com/pyroscope-io/pyroscope-rs

If someone is interested in this space, feel free to reach me!

I feel some of the OP points. I was working on a profiling agent lately, and one of the issues was running it on multiple platforms (just the four big ones linux/mac-x86/arm) on FFI (because it'll be run directly from python/ruby/etc...) and preferably having the thing just work without having to install or configure any dependencies.

Like OP I hit two walls: libunwind, and linking. For libunwind, I ended up downloading/compiling manually; and for linking there is auditwheel[1]. Although it is a Python tool, I did actually end up using for Ruby (by creating a "fake python package", and then copying the linked dependencies).

It was at that time that I learned about linking for dynamic libraries, patchelf and there is really no single/established tool to do this. I thought there should be something but most people seem to install the dependencies with any certain software. I also found, the hard way, that you still have to deal with gcc/c when working with Rust. It does isolate you from many stuff, but for many things there is no work around.

There is a performance hit to this strategy, however, since shared dynamic libraries will be used by all the running programs that need them; whereas my solution will run its own instance. It made me wonder if wasm will come up with something similar without affecting portability.

Finally, the project is open source and you can browse the code here: https://github.com/pyroscope-io/pyroscope-rs

Thanks to the maintainers at pprof-rs for helping us figure out how we can modify their profiler to create our rust agent (https://github.com/pyroscope-io/pyroscope-rs).

The biggest benefits we derived from Tauri were Wry and the sidecar mechanism. Wry (the second half of Tauri: tao/wry) is a cross-platform WebView rendering library in Rust that supports all major desktop platforms like Windows, macOS, and Linux. It essentially spins up a native web view from whatever operating system it’s running on and doesn’t require an application to bundle one with it. Wry greatly reduces the overhead of “pushing” a browser to our users, instead leaning on the host OS to handle rendering a web view. This made our applications really lean.

Check out https://tauri.app/ - specifically, https://github.com/tauri-apps/wry, which provides a cross-platform interface to the system's WebView.

Tauri uses WebkitGTK, which has pretty bad performance compared to other browsers on the same hardware.

One small note regarding Native Webview meant above. You can find ultimate information on this topic here. In a nutshell, Tauri applications use as HTML renderer Webkit (safari engine) on MacOS, Microsoft Edge WebView2 on Windows, and WebKitGTK on Linux (port of Webkit for Linux). Pay attention to the fact that a Tauri application could behave differently on different platforms according to the information above.

wry looks like a better choice, but no one has bothered to work on this task, yet.

I think this might be somewhat close to what you're looking for: https://github.com/tauri-apps/wry

They're wrapping the Android webkit/webview stuff in wry and creating an activity for it. I imagine they've already achieved or are close to achieving full parity API-wise to proper Tauri desktop apps.

Another way to approach it is to wrap the web app in a webview and use Tauri for custom logic, see https://github.com/tauri-apps/wry. You'd need to teach yourself some Rust though. I'm sure you could achieve something similar with Express. The performance will be similar to using a browser so not terrible.

It uses the WebView that the underlying OS provides to render the application’s UI — this is one of the reasons why the application binaries are smaller (as compared to electron). The WRY library from the Tauri toolkit provides a unified interface to interact with WebViews provided by different operating systems. The WRY library uses the Tao crate for cross-platform window management.
