See UStudio in action

From IntelliSense setup to Blueprints read as C++, live coding and one-click fixes: the whole workflow in a minute and a half.

UStudio Pro: Next-gen C++ workflow for Unreal Engine

Everything Unreal, in one extension

Built for how Unreal developers actually work

UStudio understands reflection macros, RPCs, .generated.h, Build.cs, Blueprints and the running editor out of the box.

Code intelligence that speaks Unreal FreePro

Automatic clangd and IntelliSense setup with module PCHs, so code that compiles never shows false errors. On top: smart F12 between .h, .cpp and _Implementation, real-time reflection sync and a Ctrl+. implementation generator.

used by 4 · 2 Blueprints UFUNCTION(Server, Reliable, WithValidation) void Server_Throw(const FVector& Dir); // F12 → Server_Throw_Implementation void AMyActor::Tick(float DeltaTime) { Super::Tick(DeltaTime); } | Implement

Reads your Blueprints Pro

Open any .uasset as a C++ header without launching Unreal. See which Blueprints use each function and property, and every Blueprint deriving from a class.

Live Unreal Editor

Double-click a class in Unreal and it opens in VS Code. Live Coding with Ctrl+Alt+F11, the Output Log in a panel, and C++ functions that light up while they run.

Build, debug & fix

One-click build and debug launch, readable FString/TArray values, clickable errors and fix suggestions with a multi-file diff preview before anything is written.

Node Graphs New

Build C++ and Python classes with Blueprint-style nodes, compile them into the running editor, debug them live and convert them to regular code.

Wizards & gameplay templates Pro

Visual C++ class wizard with a preview of every file
Modular Character, abilities, attributes, status effects, interactables
Real .uasset creation: GameMode, UMG widgets, Enhanced Input, DataTables
New Module & Plugin wizards with diffs of every descriptor change

Python for Unreal Editor Pro

Full import unreal IntelliSense, including your own C++ classes
Run live in the editor, or headless with UnrealEditor-Cmd
29 templates: Sequencer, Movie Render Queue, import pipelines, asset audits
Breakpoints and stepping inside Unreal Editor scripts

Git, Perforce & history

P4V-style file badges, changelists, code authors on every symbol, local file history and a Change Timeline to travel back to any point in time.

Feels familiar

Rider-style Solution Explorer with instant search, Members view, Favorites, Visual Studio / Rider keymaps and one-click layout presets.

AI agents via MCP Pro

Copilot, Cursor, Claude Code and Codex get what only UStudio knows: builds, Blueprints, inspections, templates and Node Graphs, running locally.

Real-time inspections

Catch Unreal mistakes before the compiler does

The C++ compiler happily accepts code that Unreal punishes at build, link or run time. UStudio flags it as you type, each rule with a one-click quick fix.

Include, module & linker fixes for everyone. Adds the right #include, the Build.cs dependency and enables the plugin, even for LNK2019.
Silence what you don't need. // ustudio-ignore UE001 on a line, or disable a rule project-wide.
Whole-project scan. Run every inspection on every file in one command.

UE001UObject pointer without UPROPERTY() → add UPROPERTY + TObjectPtr

UE003AddDynamic to a non-UFUNCTION → mark it UFUNCTION()

UE004Override that never calls Super:: → insert the Super call

UE005Replicated property missing from GetLifetimeReplicatedProps → add DOREPLIFETIME

UE008UObject created with new → NewObject<T> / SpawnActor<T>

UE009Type from a module Build.cs doesn't reference → add module, enable plugin

UE011Delegate handler with the wrong signature → rewrite .h and .cpp

Node Graphs · new in 1.19 - 1.22

Blueprint-style nodes that compile to real C++

Wire up a class like in the Blueprint editor, compile it into the running Unreal Editor with F7, debug it with breakpoints that pause the game, and convert it to clean, regular code when it's ready.

Get started in minutes

Three steps to a real Unreal IDE

Open your .uproject folder in VS Code, activate UStudio, let the background indexer scan your project, install the Live Bridge plugin, and start coding.

UStudio First Steps: From opening a .uproject to indexing, Live Bridge, and C++ coding

Install the extension

From the VS Code Marketplace, or Open VSX for Cursor. clangd is installed alongside automatically.

Open your .uproject folder

Click the U icon. UStudio detects the project and engine version and sets up IntelliSense for you.

Follow the guided tour

A step-by-step tour walks you through search, build, new classes, error fixes, history and Python.

Simple pricing

Free forever. Pro when you're ready.

Every install starts with a 14-day Pro trial with every feature. When it ends, UStudio keeps working in Free mode, forever.

Recent releases

Built to be trusted

Your code never leaves your machine

No telemetry

No analytics, no usage tracking. UStudio never sends your code or project files anywhere.

Local connections only

The Live Bridge and MCP server listen on 127.0.0.1 and require a per-session token.

Lightweight

A fraction of the RAM of heavyweight IDEs, with a two-phase background engine indexer.

Safe by design

Every wizard and fix previews its changes. Your settings, comments and configs are preserved.

FAQ

Questions, answered

Which Unreal Engine versions and platforms are supported?

Unreal Engine 5.0 through 5.8, on Windows 10 and 11 (64-bit), with VS Code 1.85 or newer, or Cursor.

Does it work in Cursor?

Yes. Install it from Open VSX inside Cursor. IntelliSense uses clangd as in VS Code, debugging uses CodeLLDB with Unreal's data formatters, and the Live Bridge opens classes in whichever editor runs UStudio.

What happens when the 14-day trial ends?

UStudio keeps working in Free mode, forever. You keep IntelliSense, the Solution Explorer, C++ usages, quick fixes, build, debugging, Live Coding and file history.

Is Pro a subscription?

No. Pro is a US$29 one-time purchase that includes one year of updates and unlocks up to 3 machines for your own use. After that year Pro keeps working on every version released during it. An optional US$15/year renewal adds another year of updates.

Do I still need Visual Studio installed?

Unreal Engine on Windows compiles with the MSVC toolchain, so you need the Visual Studio Build Tools (the compiler). You don't need to use the Visual Studio IDE for your daily work.

Will the Live Bridge plugin affect my teammates?

No. UStudio asks before adding the plugin, never modifies your .uproject or shared Config/*.ini, and the plugin only takes over source code access on machines where UStudio is used.

Where can I get help or report a bug?

Join the Discord community for help, bug reports, feature requests and release news, or read the User Guide (PDF).
