Should I self-host Whimsical?

YESworth it

Flowcharts go to draw.io (stateless, boots instantly), whiteboards go to Excalidraw (verified earlier on this scoreboard). Two containers replace the $10/seat and both are genuinely pleasant tools.

The math (nothing hidden, including your time)

Whimsical (Pro, per seat)	$10.00/mo
VPS share + storage	−$0.30/mo
Your maintenance: 10 min/mo at $20/h	−$3.33/mo
Net saving	$6.37/mo
Setup: 11 min measured (one-time)	$3.67
Break-even	0.6 months
Markup Index (price ÷ real self-host cost)	2.8×

What's your hour worth? $20/h$0/h = "my homelab time is free and I love it" — a legitimate position
