Design visually
Drag controls onto desktop windows or responsive web pages. Edit properties in the Inspector, anchor desktop layouts and arrange web layouts at three breakpoints.
A visual RAD tool for Visual Basic developers
Looking for a VB alternative?
Meet Objo Studio: a modern IDE with visual designers for desktop windows and responsive web pages, familiar BASIC-like code, and desktop, web and command line projects in one solution.
- Free to explore
Runs on and builds for every major desktop
- macOS Apple Silicon + Intel
- Windows x64 + ARM
- Linux x64 + ARM
Desktop and web in the same IDE
Design for the browser. Keep writing Objo.
Build customer portals, internal tools and data dashboards with a responsive visual designer. Arrange each page at Compact, Medium and Wide breakpoints, then connect forms, searchable lists, charts and custom canvas drawing to your Objo code. Built-in controls need no HTML, CSS or JavaScript.
Run the app in your browser and debug server-side events in Studio. When you are ready to ship, Publish creates one self-contained server executable for your chosen platform. Your users open a link; your server needs no separate .NET runtime. You choose and manage the hosting.

A familiar way to work
Keep the rapid workflow. Choose a fresh tool.
Objo Studio brings visual design, approachable code and debugging together in one focused environment. It keeps the productive workflow VB developers value while adding cross-platform desktop targets and responsive web apps. Keep a desktop tool, browser portal and command line utility in one solution and share the business logic between them.
Write readable code
Use a modern, statically typed, object-oriented language that is familiar but improved.
Debug with confidence
Set conditional breakpoints, use watchpoints, step through code and inspect variables. Debug server-side web events locally in Studio, or debug desktop and command line apps on remote machines.
Ship across platforms
Build standalone desktop and command line applications for every supported target from any supported development OS. Publish web apps as self-contained server executables.
Git-friendly
See changes, commit selected solution items and create or switch local branches with Studio's bundled Git integration.
Build with AI
Use an optional, provider-agnostic AI assistant that understands your project and works with Ollama, LM Studio, OpenAI, Anthropic or Gemini.
Share your business logic
Keep data models, validation and business rules in Shared Code. Use them across Desktop, Web and Command Line projects in the same solution, with APIs available to each target.
Test and measure
Run unit tests for Desktop, Command Line and Worker projects in Studio or CI with JUnit reports. Use the licensed profiler to find bottlenecks in desktop and command line apps.
Keep heavy work responsive
Desktop and Command Line apps can use Worker projects for isolated jobs across multiple processor cores. Workers stay separate processes when you run, debug and ship.
At a glance
The desktop and web RAD essentials are here.
If your shortlist starts with visual design, readable code and genuine cross-platform reach, Objo Studio is built around the same priorities.

Readable from day one
Code that feels familiar.
Objo is intentionally approachable to Visual Basic developers. Familiar constructs such as If, Then, Else, End If and statically typed variables sit alongside classes, interfaces, events, async/await and modern collections.
Meet the Objo languageAn honest statement
Objo has been built to fix the problems legacy tools have
I built Objo Studio because I still love the promise of rapid application development: designing an interface visually, writing approachable code and turning an idea into a working app quickly. But I had grown frustrated with long-standing bugs and increasingly longed for the modern language and IDE features that legacy tools were missing.
I did not want to abandon visual design. I wanted a modern version of it. Objo Studio is the tool I wanted to use: fast, visual and approachable, with a modern language and an IDE built for creating cross-platform desktop apps today. — Dr Garry Pettet
From the Objo community
What developers are saying.
Real experiences from people building software with Objo Studio.
I love Objo. It’s great to hold a brand-new RAD tool in my hands. I never would've imagined that in 2026 a new BASIC dialect would surprise me so much and reignite my curiosity.
I've long wanted a RAD environment with a comprehensive programming language that would really deliver on its cross-platform claims without being fragile or expensive. Objo Studio finally checks all those boxes -- and best of all, it's clearly a labor of love by an incredibly competent software architect. The vendor both believes in and consistently delivers on great customer service, as well as rapid progress on an impressive product roadmap. Participating in testing and evaluating Objo Studio has been such a positive and appreciated experience in a world full of mediocrity.
I have been developing software for Windows and Mac for years... Objo does live up to this promise through a smart architecture and a well implemented framework. It is a product in development but it already has a rich feature set that grows daily. Due to the absolute dedication of the developer, bugs are fixed almost immediately and new and meaningful features are added with each release. In addition, interacting with the developer is a very fun and exciting process.
Straightforward licensing
Explore for free. Pay when you're ready to ship.

- Web publishing included in the same license
- Build and publish unlimited projects
- Keep using versions released during your license
- No automatic renewal charges
Questions before you try?
Good things to know.
Can Objo Studio open my existing Visual Basic project?
No. Objo Studio does not import VB6 or VB.NET projects. It is a separate IDE and language, so an existing application must be recreated and its code adapted.
Can I build responsive web apps?
Yes. Design pages at Compact, Medium and Wide breakpoints, use built-in controls and write their behaviour in Objo. Run the app in your local browser and debug its server-side code for free. Publish creates a self-contained server executable and is included in the same license as desktop and command line builds.
How do I put a web app online?
Publish for your chosen server platform, then run the executable on your own computer or hosting provider. Studio can generate a deployment kit, but hosting is arranged separately and publishing does not upload your app. Configure HTTPS and the server for your deployment. Read the web app guide.
What are the current Web target limits?
Debug server-side web events locally in Studio with one browser session per Debug run. Web project unit tests, profiling, remote debugging and Worker pools are not currently supported. Pages use the built-in controls; arbitrary HTML, CSS, JavaScript and custom Web controls are not supported. See the Web target documentation.
Which platforms can I develop on and target?
Develop on Apple Silicon Macs, Windows or Linux and target macOS Apple Silicon and Intel, Windows x64 and ARM, and Linux x64 and ARM. Web apps run on your chosen server platform and users access them through a browser.
What can I do without buying a license?
You can design, write, run and debug desktop, web and command line projects for as long as you like. Unit testing is also free for supported project types. A license unlocks desktop and command line profiling, builds and publishing, plus web publishing. There are no royalties or automatic renewal charges; keep using versions released during your license period and renew when you want newer versions.
Is Objo Studio affiliated with Microsoft?
No. Objo Studio is an independent product built by Pettet Industries Ltd and is not affiliated with or endorsed by Microsoft.
