The Essential SaaS Tool Stack for 2026
The exact tools I use to run a profitable SaaS business as a solo founder.
My 2026 Tool Stack
After testing hundreds of tools, here's what I actually use and pay for.
Development
| Tool | Cost | Why |
|---|---|---|
| Cursor | $20/mo | AI-powered IDE |
| Vercel | $20/mo | Deploy in seconds |
| Supabase | $25/mo | Database + auth |
| GitHub | Free | Version control |
Marketing & Sales
| Tool | Cost | Why |
|---|---|---|
| Instantly | $30/mo | Cold email at scale |
| Hunter.io | $49/mo | Email finding & verification |
| Apollo | $49/mo | Prospecting database |
| n8n | Self-hosted | Automation backbone |
Operations
| Tool | Cost | Why |
|---|---|---|
| Linear | Free | Project management |
| Notion | $10/mo | Knowledge base |
| Cal.com | Free | Scheduling |
| Stripe | Per transaction | Payments |
AI
| Tool | Cost | Why |
|---|---|---|
| Claude Pro | $20/mo | Writing, analysis, coding |
| Claude API | Pay per use | Custom integrations |
Total Monthly Cost: ~$250
That's it. $250/mo to run the entire operation. Compare that to the cost of a single employee.
What I Stopped Using
- Slack — Replaced with async communication
- Zoom — Cal.com + Google Meet
- HubSpot — Too complex for a solo operation
- Zapier — n8n does everything for free
Principles for Choosing Tools
- Does it save more time than it costs?
- Can I set it up in under 30 minutes?
- Does it integrate with my automation stack?
- Will it scale when I need it to?
The best tool stack is the one you actually use every day.
