Architecture work is complex.
Your tools shouldn't be.

Does your team struggle with:

  • ❌ Diagrams scattered across tools
  • ❌ No single source of truth
  • ❌ Slow, clunky enterprise architecture software
  • ❌ Hard-to-manage future state modeling
  • ❌ Difficult collaboration across teams

Atoll fixes this.

A fast, clean environment built specifically for architecture modelling — so you can focus on design instead of fighting the tool.

Fast and Lightweight

No bloat, no steep learning curve — just efficient modelling. Start designing in minutes, not days.

Collaboration

Invite teammates, collaborate on diagrams, and maintain a consistent architecture model across projects.

Versioning & Model Branches

Frequently Asked Questions

Everything you need to know about Atoll Architect

ArchiMate is the open standard for enterprise architecture modeling. It provides a common language for describing, analyzing, and visualizing enterprise architectures. Using ArchiMate ensures your diagrams are consistent, understandable across teams, and compatible with governance frameworks like TOGAF.

Atoll Architect currently supports ArchiMate 3.2 for enterprise architecture, plus cloud application and infrastructure diagrams for AWS and Azure. We're actively working on BPMN 2.0 and UML support, which will be available soon.

What makes Atoll unique is that all notations are linked into our unified metamodel. This means whether you're creating an ArchiMate capability map, an AWS infrastructure diagram, or a BPMN process flow, everything contributes to your architecture repository and your organization's architecture knowledge. No more siloed diagrams—everything connects to build a complete picture of your enterprise.

Yes! We offer a free Starter tier so you can try Atoll Architect with no credit card required. You can create diagrams, explore features, and see if Atoll is right for your team. Upgrade to a paid plan when you need more capacity or additional features. The Starter plan is perfect for solo architects and small projects.

Absolutely! Atoll Architect is built for team collaboration. Multiple team members can work on the same diagram simultaneously, leave comments, and see collaborators on diagram in real-time. Model updates like new elements and branches are synced in real-time so everyone stays on the same page.

Currently you can export diagrams to PNG and model information like elements can be exported to CSV. This makes it easy to include your architecture diagrams in presentations, documentation, reports, and governance reviews. All exports maintain professional formatting and high quality.
We're working on adding more export formats including ArchiMate Model Exchange File, JPEG and SVG.

Model branching lets you create alternative versions of your architecture models without affecting the production/current state version. This is perfect for exploring future-state scenarios, testing what-if changes, or preparing for transitions. When you're ready, you can merge branches back into your primary model.

Yes. We take security seriously. All data is encrypted in transit and at rest. We use industry-standard security practices, security monitoring and scanning.

We don't currenlty support importing diagrams and content yet. We understand how important this is when getting started with a new tool and we're working on adding support for this in the future.

We provide email support for all users. Professional and Enterprise customers get priority support with faster response times. Enterprise customers also get dedicated account management, onboarding assistance, and training sessions for their teams.
