Quick Start
# On your VPS (Ubuntu)
wget https://dokku.com/install.sh

# On your laptop

git push dokku main
# App deployed with SSL at https://my-app.your-domain.com
Why Developers Switch from Heroku
Heroku's free tier is dead and paid plans start at $7/dyno:
- $5/month — run 5-10 apps on one VPS
- No vendor lock-in — your server, your data
- Git push deploy — same Heroku workflow
- Unlimited apps — limited only by server resources
A developer paid $35/month for 5 Heroku dynos. After Dokku on a $6/month DigitalOcean droplet: same 5 apps, same git push workflow, 83% cost reduction.
