Cratis Studio is a collaborative platform for event modeling, event storming, and domain-driven design. Align your entire team around a shared understanding of how your system behaves — before a single line of production code is written.
From the first sticky-note brainstorm to the full event model — Cratis Studio keeps everyone on the same page.
Lay out commands, events, and read models on a collaborative timeline. Visualize every state change in your system before you write a line of code.
Run a digital Event Storming session. Drop sticky notes on an infinite canvas, cluster ideas, and discover the events that really drive your domain.
Connect events to read models automatically. Understand exactly which events feed every projection before any implementation begins.
Invite developers, domain experts, and product owners. Everyone edits the same living model in real time, no merge conflicts, no stale docs.
Generate type-safe C# commands, events, and projections directly from your model. Your design and your codebase stay perfectly in sync.
Organize work across multiple applications and tenants. Keep each bounded context neatly separated while sharing the platform.
Place commands, events, and read models on a shared timeline. Drag to reorder, collapse modules, link swimlanes — and get instant visual clarity on how every state change flows through your system.
Run a digital Event Storming workshop on an infinite canvas. Throw down sticky notes at full speed, cluster them by theme, color-code by author, and export a refined event catalog when you're done.
Run an Event Storming session with your team. Dump every domain event on the canvas — no judgement.
Organise events into commands and read models on the event modeling grid. Define your bounded contexts.
Cratis generates type-safe C# commands, events, and projections that match your model exactly.
As requirements change, update the model first. The generated code stays in sync automatically.
Cratis Studio is built on top of Cratis Chronicle — an open-source event-sourcing platform for .NET. Every state change is captured as an immutable event. You get a full audit log, time-travel debugging, and the ability to replay history into new projections.
Join teams using Cratis Studio to align business and engineering around a shared model. Free to get started — no credit card required.
