Everything you need to build cross-platform desktop and command line apps

Objo Studio is a complete development environment - visual designer, code editor, debugger and build system, all in one window. Write your app once and deploy it to macOS, Windows and Linux.

Visual Designer

Design your user interface by dragging and dropping from a comprehensive library of built-in controls such as buttons, text fields, list boxes, tree views, tab panels, charts, date pickers, colour pickers and more. Set properties in the inspector and see changes instantly. Anchor controls to window edges so your layout resizes gracefully. Drop non-visual components like AudioPlayer onto the shelf and wire them up in code. What you see in the designer is what your users get.

Intelligent Code Editor

An editor purpose-built for Objo. Autocomplete suggests members as you type, with full parameter hints. Jump to any symbol definition instantly. Code folding keeps large methods manageable. The auto-formatter tidies spacing and keyword casing as you work, so your code stays consistent without thinking about it. Switch between light and dark themes, and customise every syntax colour to suit your preferences.

Powerful Debugger

A professional grade debugger. Set breakpoints on any line, add conditions so they only fire when an expression is true, and step through your code with Step Over, Step Into, Step Out or Run to Cursor. Inspect every variable in scope and read the call stack to understand exactly how you got here. Break on exceptions to catch problems the moment they happen.

Cross-Platform

Build for any desktop target from a single codebase: Windows x64 and ARM, macOS Apple Silicon and Intel, Linux x64 and Linux ARM. Develop on any OS and target any OS. Need to debug a Linux app from your Mac? Connect to a remote machine over the network and debug it as if it were running locally.

One-Click Build

When you're ready to ship, click Build. Objo Studio compiles your project to bytecode, bundles everything into a single self-contained executable - no runtime to install, no dependencies to manage. Pick your target platform and go. On macOS you get a native .app bundle. On Windows, a standalone .exe. On Linux, a single binary.

Class MainWindow Inherits Window

  Event Opening()
    Var greeting As New Label
    greeting.Text = "Hello, World!"
    greeting.Bold = True
    Self.Add(greeting)

    Var btn As New Button
    btn.Text = "Click me"
    btn.Top = 40
    AddHandler btn.Pressed, AddressOf OnButtonPressed
    Self.Add(btn)
  End Event

  Sub OnButtonPressed()
    MessageBox("It works!")
  End Sub

End Class

Easy to Use Language

Objo is a statically typed, object-oriented language with clean BASIC-like syntax. Everything is an object. Define classes with inheritance and interfaces, add properties, methods, events and enumerations. Organise shared code in modules. Write documentation comments and see them surface in autocomplete and hover tooltips throughout the IDE.

Built-In AI Assistant

Objo Studio integrates with Ollama, LM Studio, OpenAI, Anthropic and Gemini - local or cloud, your choice. The AI can read your project structure, inspect source files, check compilation errors, search your code and even make edits, all through a chat panel in the IDE. Give it per-project instructions to tailor its behaviour. Prefer to work without AI? Just leave it off - it's entirely optional.

Remote Debugging

Install the Objo remote agent on any machine on your network and it appears automatically via zero-configuration discovery. Deploy your app's bytecode over TCP, attach the debugger, and step through code running on a different OS as if it were local. Debug a Linux server app from your Mac or a Windows desktop app from Linux - full breakpoints, variable inspection and stepping, all over the network.
