Three Solo Founders, Three Zero-Dollar Stacks: What Running a Real Business on Free Hosting Actually Looks Like

Free hosting gets dismissed a lot as a hobbyist thing — the place where you park a portfolio or tinker with a side project. But spend any time in indie hacker Discords or r/SaaS, and you'll keep running into the same breed of person: a solo founder quietly running a real, revenue-generating business on infrastructure that costs them exactly nothing.

We found three of them. All US-based, all making money, all paying $0/month for hosting, databases, and email. We asked them to open the hood on their stacks, walk us through their worst outages, and explain what it would take to get them to finally pay up.

The Consultant Who Refuses to Pay for Servers

Marcus, a freelance backend developer in Columbus, Ohio, runs his client portal and scheduling tool on a free container hosting tier paired with a free Postgres database from a managed cloud provider. His entire stack — hosting, database, transactional email on a free tier, even DNS through a free plan — costs him nothing.

"Clients don't care where it runs," he told us. "They care that it works when they click the link."

That said, his breaking point is real. His container host spins down idle instances, so the first load after a quiet stretch can take several seconds. For a scheduling tool, that's an awkward first impression. His workaround: a free uptime pinger that hits the app every few minutes to keep it warm. It's duct tape, but it's free duct tape.

When would he pay? "The day a client complains about speed and I can't fix it with config," he says. "So far, I've always been able to fix it with config."

The Newsletter Operator Living on Free Email Tiers

Dana runs a niche newsletter out of Austin covering Texas craft beverage regulations — a genuinely useful product that a few hundred subscribers happily pay for. Her entire delivery stack runs on free tiers: a static site on a free host, a free relational database tier for subscriber records, and a transactional email provider's free allotment for sends.

Her math is simple. The free email tier covers her current volume, and because her product is the content — not the app — her infrastructure needs are unusually shallow. "I'm not running a web app. I'm running a website and a mailing list. Paying $20 a month for that felt silly."

The catch she's hit more than once: free email tiers come with daily send caps, and she's burned through them on days with big regulatory news. Her mitigation is boring but effective — scheduling sends across days and keeping a paid tier bookmarked as an emergency lever she hasn't had to pull.

The App Founder Who Stacked Six Free Tiers Into One Product

Priya, based in the Research Triangle area of North Carolina, built a small B2B tool for local gyms that manages class schedules and member check-ins. It has paying customers. It also has — by her own count — six different free tiers holding it up: app hosting, database, object storage, auth, email, and monitoring.

Her stack is the most impressive and the most fragile of the three. Because she's stitched together so many free services, she's had to become an expert in each provider's limits. "I have a spreadsheet," she admits. "Every tier, every quota, every reset date. When something breaks, I check the spreadsheet before I check the logs."

Her worst incident: her free database tier hit its connection limit during a spike of gym check-ins on a Monday morning. A quick read-replica-free fix — connection pooling — solved it, but she calls it "the closest I've come to paying for anything."

The Patterns Worth Stealing

Across all three interviews, a few habits showed up again and again:

• They know their limits cold. Every founder could recite their quotas from memory (or from a spreadsheet). Free tiers punish people who don't.
• They architect for spin-downs. Cold starts are treated as a design constraint, not a surprise.
• They keep an exit plan. Each one has a paid fallback identified, priced, and ready — they just haven't needed it.
• Their products are forgiving. None of them run anything latency-critical or high-traffic enough to make free tiers genuinely painful.

The Honest Caveat

We'd be doing you a disservice if we framed these stories as a universal blueprint. All three founders run products with modest, predictable traffic. If you're building the next viral consumer app, this lifestyle is not for you — we've written before about how quickly free tiers melt under a traffic spike.

But if you're a freelancer, a consultant, or a solo founder selling something niche to a few hundred customers, the zero-dollar stack isn't a fantasy. It's a legitimate business decision, and for these three, it's been the difference between profitability and not.

Their shared advice: treat free tiers like a business expense you're choosing not to have — and have the paid upgrade one click away for the day that changes.
