Tired of chasing freelance gigs or waiting on client feedback? What if you could build something once and get paid over and over again?

That’s the magic of SaaS Software as a Service. It's how solo devs and small teams are turning their spare-time projects into real businesses. And no, you don’t need funding, a big team, or a million-dollar idea. Just a real problem, a bit of code, and the drive to ship.

What’s SaaS in Simple Terms?

You know tools like Google Docs, Notion, Canva, or even those AI image generators everyone’s using? Yep—they’re all SaaS. Software delivered through the browser, usually for a recurring fee. Now, imagine if you built your own... even something small.

Because small SaaS is big business right now.

Why You (Yes, You) Should Care

  • It’s scalable: You build it once, and it can serve hundreds or thousands.
  • You control everything: Features, pricing, roadmap—no clients calling the shots.
  • Low barrier to entry: Many successful SaaS tools started as side projects by solo devs.

Beginner or intermediate? Doesn’t matter. There’s space for everyone. You don’t need to build the next Slack—just build a solution that actually solves something.

How to Get Started

Here’s the playbook:

1. Find a Real Problem

Don’t overthink it. Look at what frustrates you or others. Freelancers managing invoices? Small biz owners scheduling clients? Content creators needing faster workflows?

2. Start with What You Know

Use the frameworks and tools you’re already comfortable with. That way, you don’t get lost in tutorials—you get building.

3. Build an MVP (Minimum Viable Product)

No bells and whistles. Just core functionality that delivers value. You can pretty it up later.

How You Can Make Money from It

SaaS gives you multiple monetization paths:

  • Freemium + Pro Features: Basic is free. Power users pay.
  • Monthly/Yearly Subscriptions: Recurring revenue, baby.
  • One-time License Sales: Especially good for dev tools or niche B2B.
  • Pay-per-use APIs: Build a simple API and charge by request volume.

A Taste of the Idea Buffet

I’ve included a full table in the main post showing SaaS ideas by:

  • Skill level (beginner → intermediate)
  • Tech stack (Django, Node, Laravel, React, etc.)
  • Problem solved
  • Monetization strategy

Examples include:

  • A resume website builder
  • An invoice generator for freelancers
  • A link-in-bio tool for content creators
  • A simple habit tracker with gamified streaks

Each of these can be built solo and monetized smartly.

Bottom Line

You don’t need to be a startup founder to build a SaaS. You just need a real-world problem and the willingness to launch. Forget chasing perfection—done and simple beats perfect and invisible.

Start small. Launch fast. Iterate based on feedback.

And don’t forget to market it—because “build it and they will come” is a fairytale.

There’s a lot more to explore—like how to pick the right stack for your idea, different ways to monetize beyond just subscriptions, and what kinds of niches are worth targeting as a solo dev. I covered all of that (and more) in a longer post over on Kumotechs. If you’re serious about turning your side project into something that earns, it’s worth a look.
