boundr is a collaborative platform for Bounded Context Canvases — the essential DDD tool for defining clear boundaries, ownership and communication between your teams.
Free forever for up to 3 canvases. No credit card required.
Full implementation of the DDD Crew canvas: strategic classification, ubiquitous language, roles, decisions, inbound/outbound communication.
Your canvases are automatically saved and synced. Work from anywhere, on any device. Local draft recovery for offline resilience.
Invite team members, assign roles, organise canvases into workspaces. Real-time presence shows who's editing what.
Create read-only share links for stakeholders. No account needed to view. Perfect for architecture reviews and workshops.
Export canvases as PNG, PDF or JSON. Import from Markdown. Integrates with your existing documentation workflow.
Save named versions, preview past states, restore with one click. Never lose a previous iteration of your domain model.
Join teams using boundr to bring clarity to their architecture. Start with 3 free canvases — upgrade when you need more.
