Choose the plan that fits your team.
Start free. Upgrade only when your architecture starts growing.
The change teams actually notice
Not better diagrams — a better answer to “why does the system look like this?”
We finally know why architecture changed.
Architecture reviews became part of our SDLC.
Every service has ownership.
We stopped losing architecture decisions.
Stop drawing architecture.
Start governing it.
Nothing about the diagram changes. Everything about how it evolves does.

Before you decide
How are Team seats counted?
Every person in the workspace who can open or review an architecture counts as one seat, including you. Roles are set per member — editors propose and review changes, viewers read and comment.
What happens to my private architectures if I downgrade?
Nothing is deleted. Private architectures beyond the Free allowance become read-only until you either make them public or upgrade again. Your history stays intact either way.
Does Free really include unlimited architectures?
Public ones, yes — unlimited, forever, with the complete editor. Free is capped at two private repositories. Diagramy never limits what you can model; the paid plans are about how architecture is reviewed and governed.
Can I change plans at any time?
Yes. Upgrades apply immediately and downgrades take effect at the end of the billing period. Everything is self-serve — there is no sales call and no annual commitment.
Do I need Team to use version history?
No. Pro gives one person the full version-control loop: branches, semantic diff, unlimited history and restore. Team is what adds other people to that loop — reviewers, approvals and protected main.
Is my architecture data private?
Private architectures are visible only to members of your workspace. Share links and embeds are opt-in per architecture and can be revoked at any time.
Software architecture deserves pull requests.
Architecture is too important to edit directly. Every architectural decision deserves a review.
Version control isn’t just for code anymore.
