  • How I built my own Railway at just just $2/mo with 4 CPU cores and 7.7 GB of RAM; INSANE!
    Coolify puts those tasks behind a web interface. It is an open-source, self-hosted platform for deploying applications and databases to infrastructure you control. - Source: dev.to / 15 days ago
  • Self-Hosted vs. SaaS: What Coolify Actually Costs (and Where It Gets Expensive)
    That's the gap Coolify walks into. It promises the thing a lot of teams have been quietly thinking: why pay $20 per seat or $25 per process to a US platform when a $6 server hosts the same app? The answer isn't "never" and it isn't "always." It's a calculation โ€” and that calculation has one line item both sides conveniently leave off the landing page. - Source: dev.to / 16 days ago
  • The Cheapest Way to Self-Host Memos in 2026
    Install Coolify (free, open source) on a VPS and deploy Memos from its catalog. You get a web UI and auto-updates, but Coolify itself wants ~2 GB of RAM, which is heavier than the app it is managing. Worth it only if you are already running Coolify for other apps. - Source: dev.to / about 1 month ago
  • The $847/year Developer Tool Stack That Replaced My $4,200 SaaS Subscriptions
    Coolify is a self-hosted PaaS. Deploy from git, automatic SSL, databases โ€” basically Vercel/Heroku but on your own $5/month VPS. - Source: dev.to / 4 months ago
