Hi HN,For the last ~15 years I've worked on embedding web browsers into Java and .NET desktop apps (JxBrowser, DotNetBrowser). Over time, I watched many teams move from embedding web views into native apps, to building full desktop apps with frameworks like Electron and Tauri.Both are useful, but in practice I kept running into several problems.With Electron, beyond the larger app footprint, I often ran into: - lack of type-safe IPC - no source code protection - weak support for the modern web stack Tauri solves some problems (like app size), but introduces others: - different WebViews across platforms → inconsistent behavior - requires Rust + JS instead of a single stack So we built MōBrowser, a framework for building desktop apps with TypeScript, Node.js, and Chromium.Some of the things we focused on: - typed IPC using Protobuf + code generation (RPC-style communication instead of string channels) - consistent rendering and behavior across different platforms - Node.js runtime - built-in packaging, updates, and scaffolding - source code protection - small delta auto-updates The goal is to let web developers ship desktop apps with a web stack they already know and fewer cross-platform surprises.I'd especially love feedback from people who have built production apps with Electron or Tauri.Happy to answer any questions.

Could you build this?
No Building a custom cross-platform desktop runtime embedding Chromium/WebViews with type-safe IPC across multiple OSs requires deep native systems programming (C++, Rust) and OS-level windowing experience.
What it would actually take: This framework requires native C++ or Rust bindings to Chromium (CEF) or native platform web engines, implementing custom multi-process architectures, window management, and native OS message loops on Windows, macOS, and Linux. The hard part is building reliable, zero-copy, typed binary IPC serialization between V8 isolates and native processes while ensuring thread safety and sandboxing. It requires senior systems software engineering experience in browser internals and desktop framework architectures.
