Running a SaaS business alone means every tool choice matters. You don't have a DevOps person to manage infrastructure, a designer to make things pretty, or a marketer to handle outreach. The tools you pick need to be force multipliers, not time sinks.
After building and running a solo SaaS for 12 months, here's the exact stack that works — categorized by what you actually need at each stage.
The $0/Month Stack (Pre-Revenue)
Before you have paying customers, spend as little as possible. Every dollar you burn extends your runway.
Code Editor: Cursor ($0)
Cursor's free tier includes AI-powered code completion that genuinely speeds up solo development. VS Code is the fallback if you prefer no AI.
Why not GitHub Copilot? Copilot costs $10/month. Cursor's free tier does 80% of what Copilot does. Save the $10 until you have revenue.
Hosting: Vercel ($0)
Vercel's hobby plan handles most solo SaaS needs:
- 100GB bandwidth/month
- Serverless functions
- Automatic HTTPS
- Edge network
- GitHub auto-deploy
When to upgrade: When you hit 100GB bandwidth or need team features. For most pre-revenue SaaS products, this takes 6-12 months.
Alternative: Railway ($5/month credit free). Better for backend-heavy apps that need persistent servers.
Database: Supabase ($0)
Supabase's free tier is extraordinarily generous:
- 500MB database
- 50,000 monthly active users for auth
- 1GB file storage
- Realtime subscriptions
- Edge Functions
Why not Firebase? Supabase gives you PostgreSQL, which is a transferable skill. Firebase locks you into Google's proprietary database. For a solo founder, avoiding vendor lock-in is critical.
Payments: Lemon Squeezy ($0)
No monthly fee. They take 5% + 50¢ per transaction (higher than Stripe's 2.9% + 30¢) but they handle all sales tax, VAT, and compliance as a Merchant of Record.
When to switch to Stripe: When you're doing $5,000+/month in revenue and the 2% fee difference matters more than tax automation convenience.
Analytics: PostHog ($0)
1 million events/month free. That's enough for a SaaS with 1,000+ active users. PostHog includes:
- Product analytics
- Session replay
- Feature flags
- A/B testing
Why not Google Analytics? GA4 tells you about pageviews. PostHog tells you about product behavior — which features users actually use, where they drop off, and what paths lead to conversion.
Email: Resend ($0)
3,000 emails/month free. For transactional emails (welcome, password reset, receipt), this is plenty until you have thousands of users.
For marketing emails: Mailchimp Free (500 contacts) or ConvertKit's free plan (1,000 subscribers). See our Mailchimp vs ConvertKit comparison.
Project Management: Notion ($0) or Linear ($0)
Notion if you also need docs, wikis, and content planning. Linear if you want a clean, fast issue tracker without the noise.
Don't use ClickUp or Monday.com. They're built for teams of 10+, and you'll spend more time configuring than actually building. Read our Notion review for a deep dive.
The $20-50/Month Stack (First Customers)
Once you have paying customers, invest in reliability and speed:
Upgrade #1: Domain + Professional Email ($15/month)
- Domain: Cloudflare Registrar (~$12/year, cheapest registrar)
- Email: Google Workspace Starter ($6/user/month) — professional@yoursaas.com
Upgrade #2: Error Monitoring — Sentry ($0-26/month)
Free tier covers 5K errors/month. When a customer hits a bug at 3am, Sentry tells you exactly what happened, in which browser, with the full stack trace.
Upgrade #3: Uptime Monitoring — Better Uptime ($0)
Free tier monitors 10 URLs with 3-minute check intervals. When your SaaS goes down, you should know before your customers do.
Upgrade #4: Customer Support — Crisp ($0)
Free tier includes a live chat widget, shared inbox, and basic chatbot. For a solo founder, Crisp is the best free option.
When to upgrade: When you're handling 20+ support conversations/week, consider Intercom ($89/month) or keep Crisp's Pro plan ($25/month).
The "I Have Traction" Stack ($100-200/month)
Revenue is coming in consistently. Now optimize for growth:
Marketing: ConvertKit ($0-29/month)
Start building an email list from day one. ConvertKit's free plan supports 1,000 subscribers. Upgrade to the Creator plan ($29/month) when you need automations and sequences.
SEO: Ahrefs Webmaster ($0) + Search Console ($0)
Don't pay for a full SEO tool until you have content to optimize. Ahrefs Webmaster Tools gives you free site audits and backlink data for your own domain.
Social Proof: Testimonial.to ($0 for 10 testimonials)
Collect and display customer testimonials. Social proof converts. Use the free tier to collect up to 10 video or text testimonials.
Background Jobs: Trigger.dev ($0)
If your SaaS needs scheduled tasks, webhooks, or background processing, Trigger.dev handles it with a generous free tier.
Tools You DON'T Need (Yet)
Solo founders waste money on these too early:
| Tool Category | Skip Until... | Free Alternative |
|---|---|---|
| Figma (paid) | You have a designer | Figma Free (unlimited personal files) |
| AWS/GCP | You need custom infra | Vercel + Supabase handles 95% of needs |
| Intercom | 20+ support tickets/week | Crisp Free |
| Segment | 10K+ users | PostHog does analytics + CDP |
| Jira | You have engineers (plural) | Linear Free |
| Slack | You have a team | Discord Free + email |
| Notion AI | Revenue covers it | ChatGPT Free + Notion Free |
Monthly Cost Summary
| Stage | Stack | Monthly Cost |
|---|---|---|
| Pre-revenue | Cursor + Vercel + Supabase + Lemon Squeezy + PostHog + Resend + Notion | $0 |
| First customers | Above + Domain + Google Workspace + Sentry + Better Uptime + Crisp | $20-30 |
| Traction | Above + ConvertKit + Testimonial.to + Trigger.dev | $50-100 |
| Scaling | Full paid tiers as needed | $150-300 |
The Golden Rule for Solo SaaS Tools
Only pay for tools that directly increase revenue or prevent revenue loss. Everything else should be free tier.
- Hosting crashes = lost customers → Pay for reliable hosting ✅
- Analytics helps you optimize conversions → Free tier is enough ✅
- Fancy project management makes you feel productive → Don't pay ❌
- Marketing emails drive growth → Pay when your list exceeds free limits ✅

Frequently Asked Questions
How much does it cost to run a solo SaaS business?
Using free tiers strategically, you can run a SaaS for $0-50/month until you have paying customers. The minimum viable stack costs about $20/month: domain ($12/yr) + hosting ($0-10/mo) + email ($0-5/mo).
What tools does a solo SaaS founder actually need?
At minimum: a code editor (Cursor/VS Code), hosting (Vercel/Railway), database (Supabase/PlanetScale), payments (Stripe/Lemon Squeezy), analytics (PostHog), and email (Resend). All have free tiers.
Should solo founders use project management tools?
Yes, but keep it simple. A Notion workspace or Linear's free plan is enough. Don't spend time configuring ClickUp or Monday.com — that complexity is for teams, not solo operators.
What's the cheapest way to accept payments for a SaaS?
Lemon Squeezy or Paddle act as Merchant of Record, handling tax collection for you. Stripe is cheaper per transaction (2.9% + 30¢) but requires you to handle sales tax yourself.
