   Visual Studio Code does not ship Lua support itself, but two free extensions turn it into a complete Lua setup. The sumneko Lua extension runs the Lua Language Server, which supports Lua 5.1 through 5.5 and LuaJIT, provides completion, hover details and diagnostics, and reads over 20 annotation types so you can document tables, classes and function signatures. Its Marketplace page lists 2,355,278 installs. The Lua Debug extension by actboy168 adds breakpoints, function and conditional breakpoints, watches, expression evaluation and stepping, and it runs on Windows, macOS, Linux and Android. For modders, the useful trick is a definition file for the game's API, which LuaLS loads so that completion knows engine functions. The trade-off is setup: you install and configure two community extensions instead of opening one purpose-built tool, and attaching to Lua embedded inside a game takes some launch configuration.

   Strengths

   • +Free for private and commercial use
   • +The sumneko Lua extension lists 2,355,278 installs on the Visual Studio Marketplace
   • +Definition files let completion cover a game's own Lua API

   Limitations

   • −Completion and debugging come from two separate community extensions
   • −No built-in knowledge of the Roblox data model, unlike Roblox Studio
   • −Debugging a game's embedded Lua needs launch or attach configuration

   SummaryVisual Studio Code is the best choice for most Lua scripters because it is free and the sumneko Lua and Lua Debug extensions cover completion, diagnostics and breakpoints. Roblox creators should still script inside Roblox Studio.

2. 2

   Roblox Studio

   Roblox's free building and scripting environment, where creators write Luau with an autocompleting Script Editor and a built-in debugger.

   8.7overall

   Roblox's free building and scripting environment, where creators write Luau with an autocompleting Script Editor and a built-in debugger.

   Best forRoblox creators scripting games in Luau

   Adoption data

   138 millionRoblox reported 138 million average daily active users in the three months ended September 30, 2026, the audience games built in Roblox Studio are published to.

   Roblox Corporation, Form 10-Q for the quarter ended September 30, 2026 (2026): “in the three months ended September 30, 2026, of our 138 million average daily active users”

   Roblox Studio is where Roblox games are built, and its Script Editor is the most context-aware Lua editing environment on this list for that one platform. Roblox's documentation says the editor formats and highlights code, offers autocomplete that is contextual to the game's data model, jumps to variable and function declarations, finds and replaces across all scripts, and gives real-time feedback on code quality and performance. Debugging is built in: breakpoints pause scripts at specific lines so you can watch variables and inspect the call stack. Studio is free, and Roblox's Form 10-Q reports 138 million average daily active users in the third quarter of 2026, which is the audience creators publish to. The limit is scope. Studio scripts are written in Luau, Roblox's Lua dialect, and the tool is useless for mods, LÖVE games or Lua embedded in other software.

   Strengths

   • +Free to use, with no paid tier needed to script and publish
   • +Autocomplete understands the instances in your own game
   • +Debugger, testing and publishing in one program

   Limitations

   • −Only for Roblox experiences, not general Lua or other game engines
   • −Scripts use Luau, Roblox's Lua dialect, rather than standard Lua
   • −Features score lower for general Lua work because of that lock-in

   SummaryRoblox Studio is the best choice for Roblox creators because its free Script Editor autocompletes against the game's own data model and debugs with breakpoints. For any Lua outside Roblox, pick VS Code or ZeroBrane Studio.

3. 3

   ZeroBrane Studio

   A lightweight, open source IDE built only for Lua, with completion, a static analyzer, live coding and a remote debugger.

   8.4overall

   A lightweight, open source IDE built only for Lua, with completion, a static analyzer, live coding and a remote debugger.

   Best forLua developers who want one purpose-built IDE with a debugger

   Adoption data

   2.8kThe ZeroBrane Studio source repository on GitHub had 2.8k stars in November 2026.

   GitHub, pkulchenko/ZeroBraneStudio (2026): “2.8k stars”

   ZeroBrane Studio is the only IDE here made solely for Lua. Its home page lists auto-completion for functions, keywords and custom APIs, a static analyzer that flags typos, non-localized variables and unused parameters, and a debugger for local and remote sessions, including on-device debugging. For game work it supports debugging LÖVE, Corona, Moai, Gideros, Marmalade Quick and Cocos2d-x, and its live coding mode reruns your program as you type, with sliders to tweak numeric values. It covers Lua 5.1 to 5.4 and LuaJIT, bundles common libraries such as luasocket and lpeg, and the Windows and macOS packages are about 6MB. The download is free; the support page suggests paying $24 or $50, or any amount. The main caution is pace: the newest listed release is v2.01 from September 2023, so check that your engine still works before standardizing on it.

   Strengths

   • +One install covers completion, analysis and debugging with no extensions
   • +Installers for Windows and macOS are around 6MB
   • +Bundles luasocket, luafilesystem, luasec and lpeg for every supported Lua version

   Limitations

   • −Latest release listed is v2.01 from September 26, 2023
   • −Smaller user base than general editors, with 2.8k GitHub stars
   • −No Luau or Roblox support

   SummaryZeroBrane Studio is the best dedicated Lua IDE because completion, a static analyzer and a remote debugger for engines such as LÖVE and Gideros come in one free download. Teams that want frequent releases may prefer VS Code with LuaLS.

4. 4

   Neovim

   A free, Vim-based terminal editor with Lua built in, which uses the Lua Language Server for completion and nvim-dap for debugging.

   8.3overall

   A free, Vim-based terminal editor with Lua built in, which uses the Lua Language Server for completion and nvim-dap for debugging.

   Best forkeyboard-driven scripters who already work in a terminal

   Adoption data

   14.7%14.7% of the 13,193 developers who answered the 2026 Stack Overflow Developer Survey question on development environments reported using Neovim regularly.

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

   Neovim has an unusually close tie to Lua: the editor embeds it, your configuration lives in init.lua, and plugins are written in it, so many people learn Lua by customizing Neovim. For editing Lua projects, its built-in LSP client provides semantic code inspection and refactoring, and the Neovim LSP documentation shows a config for emmylua_ls, while the Lua Language Server site gives install steps for Neovim users. Debugging is not built in; the nvim-dap plugin implements a Debug Adapter Protocol client that can talk to a Lua debug adapter. Neovim is free under the Apache 2.0 license and is used regularly by 14.7% of respondents in the 2026 Stack Overflow Developer Survey. It fits scripters who are comfortable in a terminal and willing to assemble their own setup, and it is a poor first choice for a modder who just wants autocomplete working in five minutes.

   Strengths

   • +Free and open source under Apache 2.0
   • +Writing Neovim plugins is itself Lua practice
   • +Runs over SSH and on minimal machines

   Limitations

   • −Language server and debugger need manual configuration
   • −Modal editing has a learning curve for new users
   • −No game engine integration out of the box

   SummaryNeovim is the best choice for terminal users writing Lua because Lua is built into the editor and its LSP client works with the Lua Language Server. Beginners will get completion working faster in VS Code.

5. 5

   IntelliJ IDEA

   JetBrains' IDE, which gains Lua completion, refactoring and a remote debugger through the EmmyLua plugin.

   8.0overall

   JetBrains' IDE, which gains Lua completion, refactoring and a remote debugger through the EmmyLua plugin.

   Best fordevelopers already using JetBrains IDEs who add Lua scripting

   Adoption data

   24.3%24.3% of the 13,193 developers who answered the 2026 Stack Overflow Developer Survey question on development environments reported using IntelliJ IDEA regularly.

   Stack Overflow, Dev IDEs, Technology data 2026, Stack Overflow Developer Survey (2026): “IntelliJ IDEA 3,201 24.3%”

   IntelliJ IDEA has no Lua support of its own, but the EmmyLua plugin, with 1,014,483 downloads on JetBrains Marketplace, adds a full feature set. The plugin page lists keyword, basic and type-inferred completion, find usages, rename, go to definition, symbol and class, parameter name hints, comment-based type annotations, a structure view, a formatter, inspections and intentions, and Lua 5.4 support. Debugging comes in two forms: a remote debugger based on mobdebug.lua, which suits games that embed Lua, and an attach debugger that only works on Windows. The Lua Language Server project also offers a SumnekoLua plugin for JetBrains IDEs. JetBrains now offers IntelliJ IDEA as a free download with 30 days of Ultimate included; paid plan prices showed in euros from our location, so the USD price is pending. This is a good fit if Lua is the scripting layer of a Java or Kotlin project.

   Strengths

   • +JetBrains refactoring and navigation applied to Lua
   • +EmmyLua shows 1,014,483 downloads on JetBrains Marketplace
   • +Free download with 30 days of Ultimate included

   Limitations

   • −Lua support depends on a community plugin, not JetBrains
   • −The EmmyLua attach debugger is Windows only
   • −USD prices could not be confirmed from our location

   SummaryIntelliJ IDEA is the best choice for developers who already work in JetBrains tools because the EmmyLua plugin adds type-inferred completion, rename and a remote Lua debugger. Developers without a JetBrains habit get the same basics free in VS Code.

   Defold

   A free, source-available 2D and 3D game engine whose editor includes a Lua code editor, debugger and hot reload.

   7.8overall

   A free, source-available 2D and 3D game engine whose editor includes a Lua code editor, debugger and hot reload.

   Best forindie developers building a whole game in Lua

   Adoption data

   6.5kThe Defold engine and editor repository on GitHub had 6.5k stars in November 2026.

   GitHub, defold/defold (2026): “6.5k stars”

   Defold is a game engine first, but its editor is where many Lua game developers spend their day. The Defold Foundation describes it as a free, all-in-one engine for 2D and 3D games in which game logic is written in Lua, and the editor bundles a code editor, a built-in Lua debugger, hot reload, fast builds and a profiler alongside scene, tilemap and particle editors. There is nothing to configure and no registration. Projects publish from one code base to consoles including Xbox, PlayStation 5 and Nintendo Switch, plus Steam, mobile and HTML5, and the site says a new release ships every month. Defold is free with no licensing cost, royalties or runtime fee. Its GitHub repository has 6.5k stars. The catch is scope: it only helps with Defold games, and for scripting other software you need a general editor. Defold also integrates with VS Code for people who prefer that editor.

   Strengths

   • +Free forever with no royalties or runtime fee
   • +No setup or registration: download the editor and start
   • +Integrates with VS Code if you prefer to edit Lua there

   Limitations

   • −Only useful for Defold projects, not mods or other engines
   • −Smaller community than general editors
   • −The editor is a game engine, heavier than a text editor for small scripts

   SummaryDefold is the best choice for indie developers building a complete game in Lua because the free editor bundles a code editor, debugger and hot reload with no royalties. Modders scripting someone else's game should pick VS Code or ZeroBrane Studio.

   7.8overall

   A fast, native code editor that adds Lua support through its Lua extension running the Lua Language Server.

   Best fordevelopers who want a lightweight native editor with LuaLS

   Adoption data

   11.4%11.4% of the 13,193 developers who answered the 2026 Stack Overflow Developer Survey question on development environments reported using Zed regularly.

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

   Zed is a native code editor that handles Lua through its Lua extension, which runs LuaLS, the same language server behind the VS Code extension, and a tree-sitter Lua grammar for highlighting. Zed's Lua documentation shows configuring the server with a .luarc.json file at the project root, where you can set the runtime version such as Lua 5.4, turn on formatting and point workspace libraries at extra definition files, which is how you teach completion a game's API. Zed is free for personal use, and Pro costs $10 per month for AI features. In the 2026 Stack Overflow Developer Survey, 11.4% of respondents use it regularly. Its Lua page covers the language server only and says nothing about a Lua debugger, so if stepping through code matters, VS Code with Lua Debug or ZeroBrane Studio is the stronger pick. Zed suits scripters who want fast LuaLS completion in a lighter editor.

   Strengths

   • +Free for personal use
   • +Same LuaLS completion engine as VS Code
   • +Same .luarc.json format used by LuaLS in other editors

   Limitations

   • −Zed's Lua documentation covers the language server, not a Lua debugger
   • −Smaller extension catalog than VS Code
   • −No game engine specific integrations

   SummaryZed is the best choice for Lua developers who want a native editor because its Lua extension brings LuaLS completion configured by a simple .luarc.json file. Anyone who needs a Lua debugger should use VS Code or ZeroBrane Studio.

8. 8

   Sublime Text

   A fast, paid text editor that gets Lua completion through the LSP-lua package with a bundled language server.

   7.1overall

   A fast, paid text editor that gets Lua completion through the LSP-lua package with a bundled language server.

   Best forexisting Sublime Text license holders adding Lua

   Adoption data

   9.8%9.8% of the 13,193 developers who answered the 2026 Stack Overflow Developer Survey question on development environments reported using Sublime Text regularly.

   Stack Overflow, Dev IDEs, Technology data 2026, Stack Overflow Developer Survey (2026): “Sublime Text 1,290 9.8%”

   Sublime Text is a fast native editor, and Lua support comes from the community LSP-lua package, which Package Control describes as a convenience package with a Lua language server bundled. Install it alongside the LSP package and you get completion and diagnostics similar to other LuaLS editors without fetching the server separately. Package Control lists about 6K total installs for LSP-lua, a small number next to the sumneko extension for VS Code. Sublime Text has no Lua debugger, so you will run and debug scripts in your game or a separate tool. A personal license costs $99 once, and 9.8% of 2026 Stack Overflow Developer Survey respondents use the editor regularly. It is a sensible place to write Lua if you already own a license and like its speed, but a new Lua scripter gets more for free from VS Code or ZeroBrane Studio.

   Strengths

   • +Fast native editor with a one-time license instead of a subscription
   • +LSP-lua bundles the server so setup is one package install
   • +Current release is Sublime Text 4, Build 4215

   Limitations

   • −No Lua debugger in the editor
   • −LSP-lua has about 6K installs on Package Control, far fewer than the VS Code extension
   • −Costs $99 when most Lua editors here are free

   SummarySublime Text is the best choice for people who already own a license because the LSP-lua package adds Lua completion with a bundled server. New Lua scripters get a debugger and the same completion for free in VS Code.
