egui review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

For Rust developers building interactive interfaces, egui is a free, open-source immediate-mode GUI library for native applications and the web. It suits teams that want to define UI as part of their Rust code rather than rely on a platform-native appearance. The library can be used on its own or integrated into a game engine or another environment that can render its output, making it relevant to desktop and web projects with different rendering contexts.

The UI toolkit covers everyday controls and composition: buttons, checkboxes, sliders, text editing, image display, and horizontal, vertical, column, and wrapping layouts. Windows and panels can be resized, scrolled, or collapsed, while a custom 2D painting API supports drawing beyond the built-in widgets. Accessibility support via AccessKit adds a further capability for teams considering how people interact with their interfaces. This breadth makes egui a flexible toolkit, though its focus remains on immediate-mode UI rather than the wider scope of a broader cross-platform framework.

For app delivery, the official eframe integration supports native apps on Linux, macOS, Windows, and Android, as well as WebAssembly apps. Related integrations include egui_glow, egui-wgpu, and egui-winit. The project is free and open source, with community support. Choose egui if your team works in Rust and wants control over an interface that need not follow native platform styling. Consider another framework if native-looking UI is a requirement or if you need a tool centered on a language other than Rust.

egui pros and cons

• Where it wins
  • Provides widgets, text editing, image display, and flexible layout tools
  • Supports custom 2D painting, resizable panels, scrolling, and collapsing sections
  • Works with eframe for native and WebAssembly apps, with AccessKit accessibility support
• Where it doesn't
  • Rust-focused, so it is not a general-purpose framework for other languages
  • Its interfaces are not designed to look like native platform interfaces
  • Support is community-based
