./savings-calculator --your-stack

How much would you save self-hosting your stack?

Plug in your current SaaS bills. See real savings against an honest VPS cost — not a fantasy of zero. Then see the self-hosted alternative for each tool you're paying for.

Pick what you're on (or leave a category blank if you don't use it). Defaults are common 2026 plan pricing — override any field with your actual bill.

Where your savings could come from

Every line you entered has a self-hosted version. This isn't a checklist to work through in order — it's just where the money is hiding. Start with whatever feels easy, or whatever's bleeding you the most. Up to you.

When self-hosting is exactly right for you

Saving money is the obvious win. But for the right builder, self-hosting unlocks something more valuable: freedom to experiment, ship faster, and own your stack forever.

+You can spin up anything in minutes

Want to try a self-hosted analytics tool, a Discord alternative, a niche password manager? With Coolify on your VPS, deploy it in one click. No new card, no new trial. Self-hosting drops the cost of curiosity to zero.

+One server, infinite side projects

A $12/mo VPS can run 10+ small projects side by side. Client demos, throwaway prototypes, weekend builds. None of them adds a separate bill. Your monthly cost stops scaling with how much you ship.

+You learn how things actually work

Every SaaS abstracts something away. Self-hosting puts you face-to-face with databases, queues, DNS, SSL, networking. That knowledge compounds across every project you build.

+You ship side projects faster

No signup forms, no payment approvals, no waiting. Need a database? Container's already running. Need email sending? Postal's right there. Friction is the silent killer of side projects — self-hosting kills the friction.

+You own your stack forever

The side project you built three years ago and forgot about? Still running. No subscription to reactivate, no plan that got deprecated, no forced migration to a new tier. You own the data, the config, all of it.

+It compounds across everything

The first self-hosted tool takes a weekend. The second takes an evening. The fifth takes 20 minutes. Each one teaches patterns you reuse in the next. SaaS skills don't transfer like this.

The honest test: if you're the kind of builder who reads release notes for fun, likes understanding what's under the hood, and wants to ship more without scaling your monthly bills, self-hosting is one of the highest-leverage skills you can pick up.

When you should NOT self-host

Self-hosting saves money, but it costs time, attention, and a willingness to be the one who fixes things. Here's when paying for SaaS is the right call.

×You'd rather pay than learn

Nothing wrong with this. Some people love the infrastructure layer; others want to stay focused on product, marketing, or design. Know which one you are.

×You don't have time to learn the basics

Linux, Docker, DNS, SSL certificates, backups. You don't need to be an expert, but you need to be willing to learn. If you can't carve out the time right now, the SaaS bill is worth it.

×Your volume is low

If your total SaaS spend is under $40/month, self-hosting probably costs more time than it saves money. The math works at scale, not at small.

The honest part: this list is shorter than it used to be. With AI and step-by-step guides, building and maintaining self-hosted tools like Coolify is easier than ever. Plenty of times you'll fix a problem yourself faster than you'd get an answer out of a managed host's support queue. The real tradeoff isn't difficulty anymore, it's ownership: when something breaks, you're the one who handles it. If that sounds fine to you, you're ready.


Frequently asked questions

Honest answers to the questions builders ask before they commit to the swap.

How accurate are these savings estimates?
The defaults use representative 2026 plan pricing for each SaaS provider, and the math subtracts an honest VPS cost (not zero). Your real number will vary based on your actual bills, usage volume, and which plans you're on — override any price field with your real invoice to get a precise estimate.
Is self-hosting actually worth the time?
Below ~$40/month of total SaaS spend, the math rarely works — your time is worth more than the dollars you'd save. Above ~$100/month, the savings compound: every new tool you self-host adds revenue without adding a subscription. Many builders also find the ops experience and stack ownership more valuable than the dollar savings.
How big a VPS do I actually need?
This calculator scales VPS cost with category count: light setup (1–2 tools) on a ~$6/mo VPS, medium (3–4) on ~$12/mo, heavy (5+) on ~$25/mo. A single mid-tier VPS comfortably handles email + hosting + databases + automation for most solo builders. See the Coolify starter guide to set one up.
What if I'm not technical enough to self-host?
Coolify makes most of the work click-through — deploys, HTTPS, persistent databases, one-click updates. Postal SMTP, Mautic, and more install in roughly 5–30 minutes following the guides on this site. The learning curve is real but bounded; you're not running infrastructure for thousands of strangers, just yourself.
What happens if my server goes down?
For a solo-builder stack: take nightly automated backups (one cron command), host on a reputable VPS provider, and you're at ~99.9% uptime. The same outage risk exists with SaaS — you just don't see it. Self-hosting moves reliability into your control instead of theirs.
