It's frustrating when a simple project requirement turns into a week-long ordeal of manual Gosu coding and you’re not sure how to do it. We’ve all been there, waiting for the local environment to load and hoping that your manual API extensions were developed correctly, or dreading having to do it all again. This manual, code-heavy process is the "old way" of working that creates a high domain barrier and slows our collective speed to market.
With the arrival of Schema Editor in the Olos release (GA as of January 9th, 2026), we are witnessing a fundamental shift in how InsuranceSuite applications are configured. This update is a no-code visual editor natively built as a new Guidewire Home application that empowers you to discover, design, and extend schemas in minutes instead of weeks.

The End of Gosu-first Configuration for APIs and Entities
For years, extending the data model meant creating your entity extensions in Studio, then running the Rest Endpoint Generator just to get a basic scaffolding, followed by a long list of coding to-dos. Schema Editor changes that by providing an intuitive UI where you can create entities, indexes, and APIs all at once.
Think of it as a specialized blueprinting tool for your house; instead of hand-drawing every electrical circuit (manual Gosu), you use a visual architect’s tool that automatically generates the wiring according to code standards. By using Guidewire's built-in code generation, the tool ensures that every data model and API file you create maintains the exact same level of quality, updatability, and reliability as native Guidewire APIs and ready for use.
Unified Actions for Rapid Integration
One of the most significant pain points Schema Editor addresses is the friction of trying to connect core systems to digital front-ends or integrations without the right endpoints or extensions available. Because the tool automatically generates the necessary Cloud APIs, it allows your team to quickly discover and catalog extensions for use in the Jutro Digital Platform or through the Integration Framework.
The system’s (A) composable, API-first architecture (B) offers development teams the freedom to build integrations rapidly, while it (C) establishes a foundation for continuous innovation.
What This Means for Your Next Sprint
If you are running the Olos release and Lifecycle Manager (LCM) is provisioned, Schema Editor is already included in your application subscription. You can simply submit a request to enable Schema Editor. Stop battling outdated manual reconciliation and start focusing on strategic development work that actually moves the needle.
Your immediate next steps:
- Watch the Olos demo
- Request provisioning through Community using this template
- Get ready by reading the documentation
- Reach out to Guidewire Education for a 1 day instructor led training (optional)
- Start building!
The days of manual Gosu marathons for simple extensions are over. It’s time to build at the speed of the cloud.
