- 40+ cloud components
- One-click auto-layout
- Multiplayer editing
- Well-architected reviews

Built for the whole architecture lifecycle
From the first sketch to a governed, versioned artefact, every step has a home.
Drag-and-drop HLD & LLD editor
A precision canvas with 40+ cloud-native components, smart connectors and auto-layout. Go from blank page to review-ready diagram in minutes.
ArchitectAI copilot
Generate reference architectures, explain any board, run a resilience pass and produce design docs straight from the canvas.
Real-time collaboration
Multiplayer cursors, threaded comments, mentions and version history keep architects, engineers and reviewers in sync.
Well-Architected reviews
Automated checks surface single points of failure, missing DLQs, drift from best practice and security gaps before they ship.
200+ battle-tested templates
Start from curated HLD, LLD, sequence and infrastructure patterns, or turn your own boards into reusable team templates.
Enterprise-grade governance
SSO, RBAC, audit logs, data residency and integration policies with security reviews, SOC 2 and ISO 27001 alignment.
A canvas built for architects, not drawing tools
Every primitive you need for high-level and low-level design, with the keyboard shortcuts and polish of a professional IDE.
- 40+ components across clients, services, data, messaging, security and cloud
- One-click layered auto-layout with clean orthogonal connectors
- Inline editing, status pills and health indicators on every node

healthyYour always-on staff architect
Move from a prompt to a defensible architecture fast, then let the copilot keep it honest as the system evolves.
- Generate multi-region reference architectures from a sentence
- Explain, review and refactor an existing board in context
- Produce technical design docs, ADRs and export-ready summaries
Reviewed 14 components and 22 connections. Three findings worth fixing before launch:
Review together, decide faster
Replace stale screenshots in Slack with a living document that captures the decision, the discussion and the why.
- Multiplayer editing with presence and follow mode
- Threaded comments, mentions and resolve tracking
- Full version history with named snapshots and restore

Standards that scale with the org
Give every team guardrails and visibility, from a two-person startup to a regulated enterprise.
- Reusable templates, component libraries and naming policies
- Usage analytics, audit logs and per-workspace controls
- SSO, SCIM, RBAC and data residency for enterprise
