GNOME Builder vs Lapce

GNOME Builder is a free integrated development environment for creating applications for GNOME. It integrates GTK+, GLib, and GNOME APIs, with editing features that include syntax highlighting, side-by-side editors, multi-monitor support, and a code overview mini-map. Git integration includes project cloning, and listed build integrations cover Autotools, Cargo, CMake, Gradle, Meson, Maven, Make, PHPize, and Waf. Code assistance includes Clang- and Python-based auto-completion, semantic highlighting, and diagnostics, plus Vala-based auto-completion and diagnostics. Builder offers live previews for HTML, Markdown, reStructuredText, and Sphinx, as well as optional Vim, Emacs, and SublimeText-style editing. Native applications can use its integrated debugger and software profiler. It supports jhbuild and Flatpak runtimes and integrates with arduino-cli. The app page says releases follow the GNOME schedule, every six months, and links to online help, contribution guidance, and an issue tracker. Builder is available for Linux desktops, with x86_64 and aarch64 builds listed.

Lapce is an open-source code editor written in Rust, available for Linux, macOS, and Windows. It uses a native graphical interface with GPU acceleration through Floem. For code intelligence, it combines Tree-sitter syntax highlighting with Language Server Protocol support for completion, diagnostics, and code actions. Developers can connect to a remote machine to work in an environment matching a production server, and the included terminal opens at the workspace path. The editor has built-in Vim-like modal editing and supports multiple cursors. Plugins can be written in any programming language that compiles to WASI, and the editor supports extensions. Downloads include Linux tar.gz builds for x86 and ARM, Windows system installer and portable x86 builds, and a universal macOS DMG. The product page displays version 0.4.2. Its documentation covers setup, settings, keybindings, modal editing, remote development, themes, terminal use, multiple cursors, syntax highlighting, and plugin development. The About page says Lapdev is maintained by the Lapce team and describes Lapce and Floem as open-source projects.
