Run a SaaS on $20/Month: Hostinger + DigitalOcean + Cursor Stack
Line-item budget for domain, landing page, app server, and AI coding tools — and what to upgrade first when revenue appears.
Published May 4, 2026 · 10 min read
Introduction
Founders over-provision before their first paying customer. You do not need managed Kubernetes, a $200/mo database, or three environments on day one. You need a domain, a landing page, an app server, and a way to ship code — plus Cursor to build fast.
This guide line-items a lean stack with Hostinger and DigitalOcean, shows what ~$20/month actually buys, and when to upgrade.
The ~$20/month stack
Split costs into infra (predictable) and tools (variable). Infra can stay under $11/month at MVP stage; Cursor Pro is the main software line item for most solo founders.
| Item | Provider | Typical cost |
|---|---|---|
| Domain (.com) | Hostinger | ~$1/mo (annual ÷ 12) |
| Marketing www | Hostinger shared | ~$3/mo |
| App server (1GB) | DigitalOcean Droplet | ~$6/mo |
| Volume snapshots | DigitalOcean | ~$1/mo |
| Cursor Pro | Cursor | ~$20/mo |
| Total (infra + Cursor) | — | ~$31/mo |
Hit true ~$20 all-in by skipping paid www hosting initially — point root domain at a static page on the same Droplet until you need WordPress or a separate marketing site.
What to skip at MVP stage
- Managed Postgres — use SQLite or Postgres in Docker until backups matter
- Multiple environments — staging can be a second Docker compose profile
- Premium monitoring — UptimeRobot free tier + DO alerts first
- CDN and WAF — add when traffic or abuse appears
- Dedicated email SaaS — use DNS forwarding until volume grows
When to upgrade
| Trigger | Upgrade | Rough new cost |
|---|---|---|
| First paying customer | Managed Postgres | +$15/mo |
| Slow queries / RAM pressure | 2GB Droplet | +$6/mo |
| Downtime anxiety | Uptime + error tracking | +$20/mo |
| Team of 2+ | Staging Droplet | +$6/mo |
Build vs buy on a budget
Cursor lets you build custom admin panels, webhooks, and integrations that would cost $50–200/mo in no-code tools. Buy only what saves more time than it costs — usually payments (Stripe) and email delivery (Postmark/Resend), not full backend platforms.
Common mistakes
- Paying for managed DB before you have users who need uptime
- Running app and Postgres on separate Droplets too early
- Annual tool subscriptions before product-market fit
- Ignoring domain + SSL renewal dates in calendar
FAQ
Can I run everything on Hostinger alone?
KVM VPS can work for tiny MVPs. Most Cursor-built stacks (Docker, Node, Postgres) are smoother on DigitalOcean. See our Hostinger vs DigitalOcean comparison.
Is Cursor Pro required?
Free tier works for exploration. Pro pays for itself when Agent saves you even a few hours of typing per month — most solo founders upgrade within the first week.
What about OpenAI API costs?
Budget separately — cap with rate limits and model routing. See OpenAI API integration with Cursor for production cost controls.
