My Stack: How I Run 4 SaaS Products as a Solo Developer (Tools, Costs, and Lessons)

The Products

I currently run 4 products, all built and maintained by me alone:

  1. SellerMind — Free tools for Amazon FBA sellers (fee calculator, batch label generator)
  2. PodCrisp — AI tools for podcasters (title generator, show notes)
  3. SaaSLaunch — Free landing page SEO checker for SaaS founders
  4. Parcelglance — AI-powered order tracking widget for Shopify stores

The Tech Stack

Frontend

  • Next.js — Primary framework for all products
  • Tailwind CSS — Styling (fast iteration)
  • Vercel — Hosting and deployment (free tier)
  • Cloudflare — DNS, CDN, and DDoS protection (free tier)

Backend

  • Supabase — PostgreSQL database + auth (free tier)
  • Cloudflare Workers — Edge functions for API routes (free tier)
  • OpenAI API — AI features in PodCrisp and Parcelglance (pay-as-you-go)

Development

  • VS Code — Primary editor
  • GitHub — Version control (free)
  • Cursor — AI-assisted coding when needed
  • Claude — Complex architecture decisions

Monitoring

  • UptimeRobot — Uptime monitoring (free)
  • Vercel Analytics — Performance metrics
  • Sentry — Error tracking (free tier)

Monthly Costs

Here's my actual monthly spend:

Service Cost Notes
Vercel $0 Free tier for all 4 sites
Supabase $0 Free tier covers current usage
Cloudflare $0 Free tier for DNS + CDN
OpenAI API ~$5 GPT-4o-mini is cheap
GitHub $0 Free for public/private repos
Domain names ~$4 ~$50/year split across 4 domains
Total ~$9/month

Yes, I run 4 products for less than $10/month.

Key Lessons

1. Start with Free Tools

Every product started as a free tool. Free tools:

  • Get users without friction
  • Build trust before asking for money
  • Provide SEO value (backlinks + organic traffic)

Parcelglance is the only product I plan to charge for (it's a Shopify app that reduces support tickets). The other 3 remain free.

2. Reuse Everything

All 4 products share:

  • Same auth system (Supabase)
  • Same deployment pipeline (Vercel + GitHub)
  • Same UI component library
  • Same error handling patterns

Building the second product took 40% less time than the first. The third took 60% less.

3. AI Changes the Game

With AI coding assistants:

  • I can build features 3-5x faster
  • Boilerplate is almost free
  • I focus on business logic, not implementation details

PodCrisp's AI features (title generator, show notes) were built in a weekend. Without AI, it would have taken a week.

4. SEO > Paid Marketing

All my user acquisition is organic:

  • Dev.to articles (like this one)
  • Free tools that attract backlinks
  • Community participation (Reddit, HN)
  • Word of mouth

I've spent $0 on ads. Zero.

5. Ship Fast, Iterate Later

My first versions are intentionally rough:

  • Minimal features
  • Basic UI
  • Manual processes where possible

If nobody uses v1, there's no point polishing it. If people use it, I improve based on feedback.

What's Next

  • Parcelglance R6 submission — Waiting for Shopify App Store review
  • More free tools — Considering a podcast guest finder and an Etsy profit calculator
  • Content marketing — Weekly Dev.to articles, Reddit participation
