Building a SaaS as a solo developer is the closest thing to a wealth-generating machine in software. No investors, no co-founders, no office — just you, your code, and customers who pay you every month.
Phase 1: Find the Right Problem (Week 1-2)
A good solo SaaS idea checks these boxes:
- You personally have this problem — you'll build the right solution faster
- Targets a niche, not "everyone" — easier to market, less competition
- Buildable in 4-6 weeks solo — if it needs a team and 12 months, it's too big
- Monthly recurring revenue model — predictable income beats one-time purchases
- Customers already pay for similar tools — proves there's a market
Phase 2: Validate Before You Build (Week 2-3)
The #1 mistake: building for 6 months before showing anyone. Instead:
- Create a landing page (Carrd or simple HTML) — describe the problem, your solution, and a pricing tier
- Talk to 10 potential customers — ask what they currently use and what would make them switch
- Get 50 email signups — post on Reddit, Twitter, LinkedIn, niche forums. If you can't get 50 signups, the problem isn't painful enough
Phase 3: Build the MVP (Week 3-7)
Don't overthink the stack. For solo SaaS in 2026:
- Frontend: Next.js or Remix
- Backend API: FastAPI or Hono
- Database: PostgreSQL (Supabase/Neon free tier)
- Auth: Clerk or Supabase Auth (never build auth from scratch)
- Payments: Stripe + Lemon Squeezy
- Hosting: Vercel or Railway (free tier for MVP)
Ship the smallest thing someone will pay for. Core feature only. Skip analytics dashboards, team features, and anything "nice to have."
Phase 4: Launch and Get First Customers (Week 7-8)
- Launch on Product Hunt (even 50-100 upvotes brings 500-2,000 visitors)
- Post as "Show HN" on Hacker News
- Write a launch blog post: "Why I Built X"
- Reach out to your pre-launch email list
- Engage in communities — help people, mention your tool only when it directly solves their problem
Phase 5: Pricing
| Tier | Price | Purpose |
|---|---|---|
| Free | $0 | Get users in the door |
| Pro | $15-49/mo | Main revenue tier |
| Business | $49-199/mo | 2-5x Pro price |
Charge monthly by default, offer a 20-30% discount for annual. Annual customers have dramatically lower churn.
Common Mistakes
- Building too much before launching — your MVP should feel embarrassingly simple
- Pricing too low — charge at least $15/month. Anything lower signals "not valuable"
- Giving up too early — most successful bootstrapped SaaS products took 12-18 months to reach meaningful revenue
Keep shipping. Talk to one customer every week.
