OneStream Developer Studio

Now, as a developer, OneStream gives me incredible power to solve complex problems. You know, I'm not asking for less capability. I'm just asking for more freedom. I want the freedom to use the IDEs that I want, that have features like rich IntelliSense or go-to-definition of a method or tabs, refactoring tools.

I want the freedom to use collaboration tools like Git. But most importantly, and especially in today's day and age, I want the freedom to bring AI into the loop with tools like Copilot with VS Code or Cursor or Claude.

I want all of it. So we asked ourselves a simple question. What if we could bring OneStream development into the tools that developers already know and love? And that is exactly what OneStream Developer Studio is.

It's the bridge. It's super exciting. It's the bridge between you and the IDE and tools of your choice and the bridge to AI-assisted development on OneStream. So let's take a look. This is Developer Studio.

It's a native cross-platform-enabled application. It allows you to work locally with your business rules and your workspace assemblies and manage them inside of solution repositories. So to get started, I'm going to go ahead and connect to an environment.

And this one looks good. I'll hit log on. Now, this is using OneStream Identity Server for the authentication flow, so there's nothing new for you to configure, and all of your existing security will persist.

Sweet. I can connect to any 920 environment or above. And now that I'm connected, I'm going to go up here and select Add Item. Now I can see all of the assemblies and all of the business rules that I have access to inside of the platform.

So I'm going to go ahead and search for an assembly that I want to work with. There it is. I'll select that and hit Save. And just like that, it's told me that it's created 12 files and pulled them down to my local machine.

It's super simple. And now that I have them on my local, I can open it up inside of the editors that I want. So now I've got all kinds of features, things like go-to-definition or things like IntelliSense with tab completion.

I've got the ability to rename or refactor things super easily. I've got robust searching tools. I've got collaboration tools like Git. But most importantly, I've got AI. And that is the multiplier. So let's work through a real use case where we're going to try to use AI to accelerate our development efforts.

So I'm going to go ahead to save some time and just come up here and paste a prompt and hit Go. What I've asked it to do is I've asked it to take this metadata service that gets me cubes, scenarios, time periods, and build a consolidation service.

That's going to return a consolidation hierarchy with statuses across my entities. And it gets to work. And wow, that was very, very fast. I think it's done. Yeah, let's take a look. I've got Git consolidation status and load entity members.

And sure enough, that looks great. So I'm going to go ahead and keep those changes. And just like that, AI has made a change to my assembly. I mean, I don't know about you guys, but that would have taken me like a solid afternoon of work.

And now that I've got those changes locally, I'm ready to push them back to OneStream. So I'm going to open up Developer Studio and wow, that is very bright. It's hurting my eyes. Is that bothering you guys too? Here, let's do this.

Oh, that's better. Anyway, now I can go ahead and select that assembly that we worked on. I can hit push and confirm I want to push that. Just like that, I see that I've got one updated file. And I've also got this green status letting me know that this has compiled successfully on the server.

It's super easy to use Developer Studio. And I'm so happy to say that everything that I've just shown you in Developer Studio is generally available on the new OneStream Solution Exchange. And that in itself is pretty awesome.

But to quote Doug Kinchley yesterday during the Vision keynote, if you guys would all check underneath your seats, you'll find some seatbelts and I'm going to need you to buckle up because everything that I've just shown you is nothing compared to what I'm about to show you next.

because I'm about to give you guys a preview of what the future of development on OneStream will be. But before I do, I just want to give you guys some context. A couple years ago, we built an internal framework that allowed our AI teams to create React-based web applications and push beyond the limitations of traditional dashboards.

But the plan for that was never to keep that capability to ourselves. The plan was always to extend that to our customers and our partners so that you guys have the freedom to create modern web-based experiences, host them directly inside of the platform, and securely connect them to your platform data and your business logic.

So if that sounds exciting, then allow me to paint you a picture of what development on OneStream could be in the very near future. Imagine this workflow. You use an AI design tool, maybe something like Figma Make, to rapidly prototype a financial solution.

And boy, we're in luck because I have got just that right here. So, you can see that I've generated some prompts here, and based on that, it's created this clean, modern, and responsive design. I've got cubes, scenarios, time period selection.

It renders this interactive consolidation hierarchy, and man, I don't know about you guys, but I think this looks really, really good. So now, I want to take this prototype and build the real thing. So, I'm going to come back over into my editor.

I'll go ahead and hit New Chat, and again, I'm going to paste and hit Go just to save time. And I've given it some context to that Figma Make mock-up, and I've asked it to create an Angular application for me.

And yes, you heard that right. I've given it some information about the styles and themes and architecture and standards and how it's going to interop with the platform to read and write data. And so far, it's looking really good.

I've got some data models and Angular components, and I see the interop service, and hopefully it's done soon, or else they're going to play me offstage like I'm at the Oscars. Oh, sweet. It's done. And I'm pretty happy with what I saw, so I'm going to go ahead and keep those changes.

And just like that, I've gone from a mock-up in Figma Make to a real working web application, and it's powered by all the capabilities of the OneStream Finance Engine. It's got cubes and stage and audit trails and security.

It's everything that makes OneStream special, but now with a lot more freedom for you to build. So I'll come into this new developer studio window where I can select this web tab and select that assembly and hit push, just like we did earlier with our backend code.

It's done in seconds. And here it is. That Angular web app that we've just built, it's running inside of OneStream. It's in the browser, and it's plugged right into Genesis with cubes, scenarios, time periods.

It renders that beautiful consolidation hierarchy with rich interaction. And check this out. Let's try it. I'm going to hit consolidate all, and watch just how lightning fast that this works. I couldn't even get the sentence out.

It's done. How lightning fast that this works, thanks to the power of OneStream Vertex. It's awesome. This is reading and writing data on top of that very same assembly that you guys watched me build during this demo.

But the best part about this is that this is seamlessly integrated into the same end user experience that your users already know and love. This is where AI-powered development on OneStream is headed.
