eDraw editor — system architecture diagram

Everything you need to map a system

From quick sketches to polished architecture documents.

Drag & Drop Components

Servers, databases, caches, message queues, API gateways, load balancers, CDNs, firewalls, clients and cloud services — plus shapes, notes and text for everything in between.

Smart Connectors

Wires enter nodes face-on with crisp arrowheads, labels stay centered on the line, and everything stays editable.

Live Sharing

One click creates a read-only link. Viewers watch your board update in real time — including your cursor.

Artboards & Print Sizes

A3/A4/A5, Letter, Legal, 1080p and 4K artboards — design exactly for the medium you'll present on.

Export Anywhere

PNG images, print-ready PDF, raw JSON for backup, or a generated Plan.md for your repository.

English + বাংলা

The full interface is bilingual. Switch languages anytime — your preference is remembered.

Your next architecture diagram is one click away
