Eraser

What it is for

Eraser is a hosted architecture canvas: you drop CloudFront / WAF / regional VPCs on one file, and Free is $0/member/month. Use it when the job is a diagram file you start at a public $, not when you need a $0 Excalidraw playground only.

What makes it unique: the cover is Eraser’s official cloud-network topology canvas (AWS edge-global CloudFront / AWS WAF / Shield Advanced / Route 53, frames us-east-1 N. Virginia-primary / us-west-2 Oregon-standby / eu-west-1 Ireland-EU, Transit gateway, Card vault / Data & analytics, legend VPC / subnet / security group) from eraser.io — not a logo. Soft-note: the still is the canvas itself (little surrounding chrome). The region frames are ops of the canvas.

Key features

• Region frames — us-east-1 / us-west-2 / eu-west-1 boxes (cover still; docs). One desk. Cover us-east-1 N. Virginia-primary sits here.
• Edge global — CloudFront / WAF / Shield / Route 53 on the top dashed frame (cover). An edge, not a Starter tile.
• Transit gateway — the bar linking regional VPCs (cover Transit gateway). A hub, not a file-cap meter.
• Service cards — Payments / Merchant portal / Shared services / Card vault (cover). A card, not an AI-diagram count.
• Legend — VPC / public subnet / private subnet / security group (cover). A legend, not a Business tile.
• Insert / diagram-as-code — / then Diagram as Code (quickstart). An insert desk, not a Generate CTA.

Generate / AI Diagram on the docs are AI extras (Free includes 3 AI diagrams — that cap stays in Pricing). Free / Starter / Business tiles are the meter.

Who it's for

Best fit: engineering teams who will stay on Free at $0/member/month (3 files / 3 AI diagrams / 7-day history) while they open a first region frame, then Starter at $15/member/month billed annually ($20 monthly) when they need unlimited files — not Business $45/$60 unless they need SAML / 250 AI diagrams.

Official tutorial

Official Eraser channel video: Eraser walk-thru (4 mins) (oEmbed author: Eraser; founder Shin). First-party product walk-thru; the AWS topology still is the cover. Diagram-as-code chrome on the video is ops of the canvas, not generate-on-the-Transit-gateway.
