How to Launch a Micro SaaS Side Project (With $0 Budget)

Tired of waiting for funding? Good. Here’s how to build and launch your own Micro SaaS from scratch — without spending a single cent.

🚀 What’s a Micro SaaS, Anyway?

A Micro SaaS is a lean, single-purpose software product run by a solo founder or small team. Think of it as the indie rock band of the software world: focused, personal, niche — and totally independent.

You don’t need VC funding.
You don’t need a team.
You don’t even need a budget.

All you need is a problem worth solving, and the right set of free tools.

💡 Step 1: Find a Painful Problem (Ideally One You Have)

Forget trendy ideas. Look for daily frustrations — yours or someone else’s.

  • Are you repeating the same task every day at work?

  • Is there a spreadsheet you wish had a button?

  • Have you built a tiny script that others might find useful?

👉 Use forums like Reddit, Indie Hackers, Hacker News, or niche Facebook groups to discover “I wish there was a tool that…” posts.

🔧 Step 2: Build It Fast with Free Tools

Here’s a zero-budget stack to build your MVP:

Even better? Use no-code builders like Glide or Bubble if you’re not into coding.

🧪 Step 3: Validate Before You Code Too Much

Don’t disappear for 6 months.

Instead:

  • Launch a simple landing page with a waitlist (use Carrd or [Framer])

  • Describe the problem + how you solve it

  • Collect emails (use ConvertKit or MailerLite)

Then ask:

“Would you pay for this?”
“How much would it be worth to you?”
“Do you want to beta test it?”

If no one’s interested, kill it fast and try another idea.

💰 Step 4: Monetize Without Headaches

Start with simple pricing:

  • Monthly / yearly (no free tier)

  • Use Lemon Squeezy or Gumroad to handle payments

  • Integrate Stripe only when it makes sense

Optional: Add a free trial (but set limits).

And always remember: a product that saves time or money will sell.

📣 Step 5: Market with Your Voice

You don’t need ads. You need authenticity.

  • Share your build journey on X (Twitter), Threads, or LinkedIn

  • Join Build in Public communities

  • Offer early access in niche Slack/Discord groups

  • Launch on Product Hunt

Use ChatGPT or Notion AI to help you write landing pages, blog posts, and launch emails faster.

🧠 Final Tip: Keep It Boring

The best Micro SaaS ideas are unsexy but useful.
Think: invoice generators, time trackers, niche dashboards, content tools.

You’re not trying to be the next unicorn.
You’re building a tiny digital cashflow machine — one user at a time.

🔥 TL;DR

  • Find a painful problem

  • Use free tools like Supabase, Framer, and Vercel

  • Validate before building too much

  • Keep pricing simple

  • Market in public

  • Ship fast, improve later
