A handful of plain-text lines become a laid-out, icon-accurate cloud diagram — ELK orthogonal routing, nested clouds, VPCs and subnets, and 7,800+ official AWS, Azure and GCP marks. It auto-detects your syntax, exports crisp PNGs, and runs entirely in the browser tab you already have open.

The default. Chains, fan-outs and deeply nestable groups. Every canvas edit rewrites these same lines, so the text stays the source of truth.

A -> B : labelArrow with an optional label; steps number themselves in written order

A -> B -> CChain several hops on one line

A --> BDashed — good for async / logging edges

Name (service)Icon by service nickname — fuzzy-resolved against 7,800 marks

cloud aws { vpc { … } }Nest containers freely: cloud, account, region, az, vpc, subnet, cluster, sg

A -> B [green]Per-line arrow color, or any hex

First diagram in about a minute.

Nothing to install, nothing to sign. Open the studio, type one arrow, watch it lay itself out.
