Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A lightweight C++ library for building immediate-mode graphical user interfaces, mainly for tools and games.
Open source · MIT
A small C/C++ library that shows HTML-based user interfaces in a native window.
The short answer
Choose Dear ImGui if you need…
- Game developers who want an in-engine debug or tools panel
- C++ developers building internal tools that need a quick interface
- Developers who want a small GUI library with few dependencies
Choose webview if you need…
- C or C++ developers who want an HTML-based GUI without bundling a full browser framework
- Developers building small desktop tools that need a simple window and web content
- Projects that want a single-header or amalgamated library that is easy to drop in
- Developers who need a C API that other languages can bind to

What each one is
Dear ImGui
Dear ImGui is a C++ library for drawing graphical user interfaces such as buttons, sliders, and windows. It is described as bloat-free with minimal dependencies, and it is commonly used for debug panels and tools inside games and other software. The README provided to me was empty, so this description relies mainly on the repository's description and topics.
webview
webview is a small C/C++ library that opens a native window containing a web view, so you can build a graphical app using HTML for the interface. It uses WebKit on Linux and macOS and Microsoft's WebView2 on Windows. It also supports two-way JavaScript bindings, so C/C++ code can call JavaScript and JavaScript can call C/C++.
Best for
Dear ImGui
- Game developers who want an in-engine debug or tools panel
- C++ developers building internal tools that need a quick interface
- Developers who want a small GUI library with few dependencies
webview
- C or C++ developers who want an HTML-based GUI without bundling a full browser framework
- Developers building small desktop tools that need a simple window and web content
- Projects that want a single-header or amalgamated library that is easy to drop in
- Developers who need a C API that other languages can bind to
Strengths
Dear ImGui
- Described as bloat-free with minimal dependencies
- Widely starred and actively pushed, with a v1.93.0 release listed
- Released under the permissive MIT license
webview
- Small footprint: the README describes it as a tiny library that wraps existing system web engines
- Covers Linux (GTK with WebKitGTK), macOS (Cocoa with WebKit) and Windows (WebView2)
- Offers both C++ and C interfaces, plus an amalgamated single-file build
Not ideal for
Dear ImGui
- People who want a ready-made desktop app with no coding, since this is a library for developers
- Teams that need a native-looking, polished end-user interface out of the box, because the README provided does not establish this
webview
- People who want a ready-made app rather than a library to build one (it is code you compile into your own program)
- Projects that need one identical rendering engine on every platform, since it relies on each system's web engine
- Beginners with no C or C++ experience, since setup involves compilers, CMake and system libraries
- Windows users targeting versions before Windows 11 without shipping the WebView2 runtime, which the README says must be installed
Trade-offs
Dear ImGui
- The README was not available to verify features, APIs, or setup details
- Release v1.93.0 is listed without binaries, so you build from source
- Being a library, it requires C++ programming to use
webview
- Rendering and available web features depend on each platform's WebKit or WebView2 version, so behavior can differ between systems
- Linux setup requires installing GTK and WebKitGTK packages, and the right package set varies by distribution
- No latest release is listed in the metadata, so you will likely need to pin a git tag such as 0.12.0 as the README example does
