TL;DR

I used Lovable to build a complete project management SaaS, including auth, billing, dashboards, and a landing page, in under 24 hours. Total cost: $87 (domain + Supabase). It now has 14 paying users.

I built a full SaaS in

The idea

I'd been thinking about building a lightweight project management tool for freelancers, something between a to-do list and full-blown Jira. The kind of tool I actually wanted to use myself.

The problem? I'm a designer, not a developer. I've tried no-code tools before but always hit walls with customization. This time, I decided to try Lovable.

Hour-by-hour timeline

Hours 0-4: Foundation

Started with a simple prompt: "Build a project management app with Kanban boards, task assignments, and a clean dark UI." Lovable generated the entire structure in minutes: routing, layout, components, even placeholder data.

I spent the next few hours refining the UI, tweaking colors, and adding a sidebar navigation. Each change was a chat message away.

Hours 4-10: Core features

Connected Supabase for the backend. Lovable set up the tables, RLS policies, and auth flow automatically. Added: Kanban boards with drag-and-drop, task creation/editing, project switching, and team member invites.

Hours 10-16: Polish & billing

Integrated Stripe for subscriptions ($9/mo plan). Built a landing page with pricing, testimonials, and a CTA. Added email notifications with Resend.

Hours 16-24: Launch

Deployed to Vercel, bought a domain ($12), and posted on Twitter and Product Hunt. Got 14 signups on day one, 4 converted to paid within the first week.

What it cost

  • Lovable Pro: $25/mo (already had it)
  • Domain: $12/year
  • Supabase: Free tier
  • Vercel: Free tier
  • Stripe: 2.9% + 30¢ per transaction
  • Total upfront: $87

Lessons learned

  1. Start with the UI. Lovable excels at generating beautiful interfaces. Start there and layer in logic.
  2. Use Supabase early. Don't wait, connect your database from the start.
  3. Ship ugly, then polish. Get the core flow working before you tweak shadows.
  4. The landing page matters. I spent 4 hours on it. Worth every minute.
  5. Iterate in public. Posting progress on Twitter generated most of my early users.
"The best part? I never opened a code editor. Every single change, from the database schema to the Stripe webhook: was done through Lovable's chat interface."

Would I do it again?

Absolutely. The speed-to-quality ratio is unlike anything I've experienced. Lovable isn't perfect: I hit a few edge cases with complex state management: but for 90% of what I needed, it just worked.
