   The Qt Group's own IDE for Qt, QML and C++, included in every Qt license.

   Best forQt Widgets and Qt Quick developers on any platform

   Adoption data

   1.5 million developersThe Qt Group says the Qt community, whose standard IDE is Qt Creator, consists of more than 1.5 million developers worldwide.

   Qt Group, Qt Group: company overview (2026): “The Qt Community consists of more than 1.5 million developers around the world.”

   Qt Creator is the IDE the Qt Group makes for its own framework, and it shows in the details. The product page lists language servers for QML and C++, refactoring for both, inspection of Qt classes, QML profiling, built-in Qt documentation and examples, and Qt project templates. The documentation says it understands C++, QML and JavaScript as code rather than plain text, includes Qt Widgets Designer, and builds through kits that switch between compilers, Qt versions and devices using CMake, qmake, Qbs or Autotools. Projects can use C++ or Python for application logic, and targets include desktop, embedded Linux, Android, iOS and WebAssembly. Recent releases add AI agents that analyze code, edit from prompts, run commands and trigger builds. The licensing page says the IDE is identical across the open source Community Edition and commercial licenses, though some commercial plugins exist. The main cost is not the IDE but the Qt license: closed source products need a commercial plan, which the Qt Group sells to small businesses for $618 per year.

   Strengths

   • +Same IDE in the open source and commercial Qt licenses, with fully open source code
   • +Reads qmake projects directly, which CLion cannot
   • +Targets desktop, embedded, Android, iOS and WebAssembly from one project

   Limitations

   • −Built around Qt, so it offers less for C++ projects that do not use Qt
   • −Redistributing a modified Qt Creator needs a separate agreement with The Qt Company
   • −Closed source products need a commercial Qt license, $618 per year at the small business rate

   SummaryQt Creator is the best IDE for Qt development because it is the only tool here with language servers, refactoring and profiling for QML and C++ built in by the Qt Group. It is free with the open source Qt Community Edition.

2. 2

   Visual Studio Code

   Microsoft's free editor, with official Qt extension packs for C++, QML, WebAssembly and Python.

   9.1overall

   Microsoft's free editor, with official Qt extension packs for C++, QML, WebAssembly and Python.

   Best fordevelopers who use VS Code for Qt and other languages

   Adoption data

   70.9%In the 2026 Stack Overflow Developer Survey, 70.9% of the 13,193 respondents to the development environments question used VS Code regularly, the most of any tool.

   Stack Overflow, Dev IDEs, Technology data 2026, Stack Overflow Developer Survey (2026): “Visual Studio Code 9,350 70.9%”

   Visual Studio Code becomes a real Qt environment once you add the Qt Group's own Qt Extension for VS Code. The overview splits it into packs: the Qt C++ pack creates Qt Widgets apps, generates a Qt kit for CMake projects, highlights Qt-specific file formats, opens forms in Qt Widgets Designer and debugs Qt's C++ types. The Qt Qml extension adds code completion through the QML Language Server, qmllint checks and the QML Profiler for finding performance problems in Qt Quick apps. A Qt for WebAssembly pack covers browser builds, and the Qt Python pack installs PySide6, creates Qt Quick or Widgets apps and debugs them with debugpy and the QML debugger, which makes VS Code the strongest choice here for Python Qt developers outside Qt Creator. It is free and the most used editor in the 2026 Stack Overflow survey at 70.9%. The tradeoffs are setup, since you register your own Qt install and compiler, and the lack of a built-in Qt Quick designer.

   Strengths

   • +The Qt extensions come from the Qt Group, not a third party
   • +One editor for Qt C++, QML, PySide6 and everything else
   • +Free, and the most used editor in the 2026 Stack Overflow survey

   Limitations

   • −Needs a separate Qt install and compiler, registered with the extension
   • −No built-in visual designer for Qt Quick; Widgets forms open in the external Qt Widgets Designer
   • −Qt extensions collect anonymous usage data unless you turn it off

   SummaryVisual Studio Code is the best choice for developers who mix Qt with other languages because the Qt Group's free extension packs add Qt kits, QML Language Server support, the QML Profiler and a PySide6 workflow. It costs nothing for private or commercial use.

3. 3

   Visual Studio

   Microsoft's Windows IDE, with the Qt Group's Qt VS Tools extension for Qt builds, designers and QML debugging.

   8.8overall

   Microsoft's Windows IDE, with the Qt Group's Qt VS Tools extension for Qt builds, designers and QML debugging.

   Best forWindows teams on MSBuild

   Adoption data

   27.6%In the 2026 Stack Overflow Developer Survey, 27.6% of the 13,193 respondents to the development environments question used Visual Studio regularly.

   Stack Overflow, Dev IDEs, Technology data 2026, Stack Overflow Developer Survey (2026): “Visual Studio 3,643 27.6%”

   Visual Studio is the right base for Qt teams that already live on Windows, and the Qt Group's Qt VS Tools extension does the Qt-specific work. The documentation says it integrates Qt tooling into Visual Studio 2019 from 16.11, 2022 from 17.12 and the current 2026 releases, so you can use the standard Windows environment without handling Qt build steps yourself. Its how-to pages cover Qt/MSBuild projects, loading Qt projects, starting Qt Widgets Designer, Qt Linguist and the Qt Resource Editor, enabling QML debugging, profiling Qt Quick apps, turning on the QML Language Server, visualizing C++ types, running Qt Test through a .runsettings file, debugging on Linux and cross-compiling. Visual Studio itself has 27.6% regular use in the 2026 Stack Overflow survey. The limits are the platform, since the IDE is Windows only, and licensing: Community is free for individuals, while company teams usually need Professional at $45 per user per month.

   Strengths

   • +Qt VS Tools comes from the Qt Group and is free
   • +Keeps existing MSBuild solutions instead of forcing CMake
   • +Visualizes Qt C++ types in the Visual Studio debugger

   Limitations

   • −Visual Studio runs only on Windows
   • −Community edition use is limited inside larger companies; Professional is $45 per user per month
   • −Cross-platform teams on macOS or Linux need a second IDE

   SummaryVisual Studio is the best choice for Windows Qt teams because Qt VS Tools handles Qt build steps inside MSBuild solutions and adds QML debugging. Community is free for individuals and Professional is $45 per user per month.

4. 4

   CLion

   JetBrains' cross-platform C and C++ IDE, with Qt templates, signal and slot completion and Qt debugger renderers.

   8.0overall

   JetBrains' cross-platform C and C++ IDE, with Qt templates, signal and slot completion and Qt debugger renderers.

   Best forC++ developers on CMake-based Qt projects

   Adoption data

   4.8%In the 2026 Stack Overflow Developer Survey, 4.8% of the 13,193 respondents to the development environments question used CLion regularly.

   Stack Overflow, Dev IDEs, Technology data 2026, Stack Overflow Developer Survey (2026): “CLion 630 4.8%”

   CLion is the strongest general C++ IDE for Qt if your project uses CMake. JetBrains' Qt documentation for CLion 2026.3 covers creating CMake-based Qt projects in the New Project wizard, a Qt UI Class template that writes the .ui, .cpp and .h files together, code completion for signals and slots, and Qt debugger renderers that show types such as QString and QByteArray in readable form, with Natvis renderers on the MSVC toolchain. It opens .ui files in Qt Widgets Designer, finding it through the Qt binaries folder set under the QML settings. The main gap is qmake: CLion's documentation says a pure qmake project cannot be imported directly and must be converted to CMake or opened through a compile_commands.json file, which Qt Creator can generate. CLion is free for non-commercial use with a 30-day trial for commercial use. Its regular use in the 2026 Stack Overflow survey is 4.8%, so its adoption score is lower than VS Code's or Visual Studio's.

   Strengths

   • +Qt-aware code insight on top of JetBrains C++ analysis
   • +Runs on Windows, macOS and Linux
   • +Free for non-commercial use

   Limitations

   • −Pure qmake projects cannot be imported and must be converted to CMake
   • −No Qt Quick designer or QML profiler like Qt Creator's
   • −Commercial use needs a paid license; USD price not confirmed here

   SummaryCLion is the best choice for C++ developers on CMake-based Qt projects because it adds Qt UI class templates, signal and slot completion and Qt debugger renderers to JetBrains' C++ analysis. It is free for non-commercial use.

5. 5

   Neovim

   A free, extensible Vim-based editor that reaches QML through the Qt QML Language Server.

   7.7overall

   A free, extensible Vim-based editor that reaches QML through the Qt QML Language Server.

   Best forterminal users who want qmlls in Vim

   Adoption data

   14.7%In the 2026 Stack Overflow Developer Survey, 14.7% of the 13,193 respondents to the development environments question used Neovim regularly.

   Stack Overflow, Dev IDEs, Technology data 2026, Stack Overflow Developer Survey (2026): “Neovim 1,939 14.7%”

   Neovim is a sensible Qt choice only for developers who already work in Vim. It has no Qt-specific tooling of its own, but its built-in Language Server Protocol client can talk to qmlls, the QML Language Server that ships with Qt. Qt's documentation says qmlls helps you write code in any LSP-capable editor with autocompletion, qmllint warnings, navigation and formatting, and it explains passing the build directory so qmlls can resolve C++ types registered to QML. The neovim/nvim-lspconfig project includes a ready qmlls configuration for qml and qmljs files, with a note that some distributions name the binary qmlls6. C++ code works through clangd or another server. What you give up is everything around the editor: Qt kits, Qt Widgets Designer, QML profiling and one-click deployment, which Qt Creator handles. Neovim is free under Apache 2.0 and used regularly by 14.7% of 2026 Stack Overflow survey respondents.

   Strengths

   • +Free and open source under Apache 2.0
   • +Uses the same qmlls language server the Qt Group ships
   • +14.7% regular use in the 2026 Stack Overflow survey

   Limitations

   • −No Qt kits, forms designer or QML profiler
   • −You configure qmlls, build directories and a debugger yourself
   • −Qt-specific usage is not measured, so adoption is scored below its survey share

   SummaryNeovim is the best choice for Vim users writing QML because its built-in LSP client runs qmlls, the language server Qt ships, with a ready nvim-lspconfig setup. It is free under the Apache 2.0 license.

6. 6

   Qt Design Studio

   The Qt Group's UI design and prototyping tool for Qt Quick, with 2D and 3D tooling and design tool imports.

   7.6overall

   The Qt Group's UI design and prototyping tool for Qt Quick, with 2D and 3D tooling and design tool imports.

   Best fordesigners and developers building Qt Quick UIs together

   Qt Design Studio is the Qt Group's tool for the design side of Qt Quick work, and it belongs on this list as a companion to an IDE rather than a replacement. The documentation for version 4.8.2 covers importing assets from Figma, Photoshop, Illustrator, Adobe XD and Sketch, timeline and state animations, an Effect Composer for shaders, 3D scenes with cameras, lights and materials from Blender or Maya, and previews on the desktop, Android devices and MCUs. Release 4.8.2 rebuilds its AI Assistant around MCP. The product page is clear about the limits: projects have no deployable runtime, so you still need a Qt license and an IDE such as Qt Creator to ship. The Community Edition is free but works only with open source Qt, while Professional comes bundled with Qt for Application Development and Qt for Device Creation licenses. Enterprise adds the Figma bridge, Content Library and Simulink support. No citable usage figure is published, so adoption is scored conservatively.

   Strengths

   • +Free Community Edition under GPL and LGPL terms
   • +Professional license is included with Qt for Application Development and Qt for Device Creation licenses
   • +Outputs QML that developers open in Qt Creator

   Limitations

   • −A design tool, not a full IDE: projects have no deployable runtime
   • −Community Edition works only with the open source version of Qt
   • −Figma bridge, Content Library and Simulink support need the Enterprise license

   SummaryQt Design Studio is the best choice for teams handing Qt Quick designs from designers to developers because it imports Figma and Adobe assets and outputs QML. Its Community Edition is free with open source Qt.

7. 7

   KDevelop

   KDE's free, open source IDE for C, C++, Python, QML and PHP, with Qt extras on top of Clang parsing.

   7.3overall

   KDE's free, open source IDE for C, C++, Python, QML and PHP, with Qt extras on top of Clang parsing.

   Best forLinux developers on large Qt and KDE codebases

   KDevelop is the KDE community's IDE, built with Qt and aimed at the kind of large, multi-library C++ projects that KDE and Qt themselves are. Its features page says C, C++ and Objective-C parsing is backed by Clang with extra features for the Qt framework, and Qt QML and JavaScript are fully supported with semantic highlighting, navigation and completion. It reads both CMake and QMake projects to find build targets and include paths, which helps teams that still maintain qmake files, and it shows Qt documentation, CMake help and man pages without leaving the editor. Python and PHP support come through optional plugins. The KDE apps page lists release 6.6.260803 on 2026-11-05 and a GPL-2.0-or-later license, so it is current and free. It lacks Qt Creator's designer, QML profiler and device kits, and we found no citable usage figure, so its adoption score is conservative.

   Strengths

   • +Free and open source, with monthly releases through 2026
   • +Supports QMake directly, unlike CLion
   • +Designed for projects spread across several connected libraries, as in KDE or Qt itself

   Limitations

   • −Python and PHP support need optional plugins
   • −No forms designer or QML profiler of its own
   • −No citable usage figure, so adoption is scored conservatively

   SummaryKDevelop is the best free choice for Linux developers on large Qt codebases because it parses C++ with Clang, adds Qt-specific extras and reads both CMake and QMake projects. It is free and open source.

8. 8

   Zed

   A code editor with a built-in AI agent and a community QML extension in its extension registry.

   7.3overall

   A code editor with a built-in AI agent and a community QML extension in its extension registry.

   Best forZed users who also edit QML

   Adoption data

   11.4%In the 2026 Stack Overflow Developer Survey, 11.4% of the 13,193 respondents to the development environments question used Zed regularly.

   Stack Overflow, Dev IDEs, Technology data 2026, Stack Overflow Developer Survey (2026): “Zed 1,504 11.4%”

   Zed makes this list for developers who already use it and want to keep QML files in the same editor, not as a primary Qt IDE. Its extension registry lists a QML extension by a community author at version 0.0.4, providing a language definition, grammar and language server hookup, with 72,665 downloads when we checked. C++ code uses clangd. Beyond that, nothing in Zed is Qt-specific: there are no Qt kits, no Qt Widgets Designer integration and no QML debugging or profiling, so you configure CMake builds and a debugger yourself. Zed's Personal plan is free, and Pro costs $10 per month with $5 of AI tokens, which makes it the cheapest paid plan here. It is used regularly by 11.4% of 2026 Stack Overflow survey respondents, though that figure is not Qt-specific. For anything beyond editing, Qt Creator or VS Code with the official Qt extension is the better tool.

   Strengths

   • +Cheapest paid editor on this list at $10 per month
   • +11.4% regular use in the 2026 Stack Overflow survey
   • +The free plan covers the editor itself

   Limitations

   • −QML support is a community extension at version 0.0.4, not an official Qt or Zed integration
   • −No Qt kits, forms designer, QML debugger or profiler
   • −Qt projects need manual CMake and debugger setup

   SummaryZed is a fit for existing Zed users who edit QML because a community extension adds a QML grammar and language server. Its Personal plan is free and Pro costs $10 per month.
