Everyone loves showing off their tech stack. Most cost $500+/month and include tools barely used.
Here's the opposite: every tool I actually use daily for less than a gym membership.
This isn't a "how to be cheap" guide. It's a philosophy: spend money on things that directly generate revenue, cut everything else to the bone. The best businesses I know run lean stacks. The struggling ones have 47 subscriptions and can't remember what half of them do.
The Core Stack
Claude Pro - $20/mo
My AI workhorse. Writing, coding, research, analysis. If I could only keep one subscription, it's this.
The ROI on Claude Pro is absurd. I use it to draft emails, write documentation, debug code, research competitors, brainstorm ideas, and edit content. Conservative estimate: it saves me 10 hours per week of work that would either cost me time or require hiring someone.
At $20/month, that's about $0.50 per hour of saved work. There is no better deal in software.
Notion - $10/mo
CRM, project management, documentation, content calendar - all in one tool. The free tier works, but Plus unlocks unlimited blocks.
The power of Notion is consolidation. Instead of Trello + Airtable + Confluence + a CRM, I have one tool that handles everything. Less context switching, less training time, less forgetting where information lives.
GitHub Pages + Cloudflare - Free
Static hosting that scales infinitely. No server costs, no DevOps headaches. Most side businesses don't need dynamic backends.
This combination handles millions of page views per month without breaking a sweat. Your landing page, blog, documentation - all served from edge servers worldwide at zero cost. The only time you need paid hosting is if you're running a dynamic application that requires a database or server-side processing.
Google Workspace - $6/mo
Professional email, calendar, docs. The email alone is worth it for credibility.
Sending emails from yourname@yourdomain.com instead of yourname@gmail.com is the cheapest credibility boost available. Clients notice. Partners notice. It signals you're serious about your business.
Domains - $12/year
Namecheap or Cloudflare. Don't overthink this.
A good domain is memorable and short. Beyond that, stop optimizing. I've seen people spend weeks choosing a domain for a business that never launched. Pick one, move on.
Free Tools That Complete the Stack
VS Code
Best code editor. Extensions for everything.Figma
Free tier handles 90% of design needs.Cal.com
Scheduling without Calendly's price tag.Also free: Slack (small teams), Linear (issue tracking), Loom (async video), Canva (quick graphics), Plausible alternatives (analytics).
The free tier economy in 2026 is absurd. You can run a legitimate business on $0/month in software costs if you're scrappy. I choose to pay for Claude and Notion because they provide clear ROI, not because I have to.
What I Don't Pay For
- Expensive CRM (Notion works fine under 500 contacts)
- Premium analytics (simple tools work for most businesses)
- Multiple AI subscriptions (Claude handles 95% of tasks)
- Paid hosting (GitHub Pages + Cloudflare is free and fast)
The Philosophy
Tools should solve problems, not create them. Every tool in this stack:
- Gets used daily or weekly
- Has a clear purpose
- Could be replaced if needed
- Doesn't require maintenance
Every time I add a tool, I ask: "Will this make more money than it costs, including my time to learn and maintain it?" If the answer isn't clearly yes, I don't add it.
Start with Claude and free tools. Add paid tools only when the free option genuinely limits you. Most people overspend on tools while underspending on distribution.
When to Upgrade
I'm not saying never spend money on tools. I'm saying spend only when the constraint is genuinely blocking growth.
Upgrade when:
- The free tier's limits actively cost you time (not hypothetically)
- The paid feature has clear ROI you can calculate
- You've used the free tier enough to know you actually need the tool
Don't upgrade when:
- "It might be useful someday"
- "Professionals use the paid version"
- "The free tier is embarrassing"
Most tool upgrades happen because of marketing, not need. Be honest about what actually limits your work versus what just seems limiting.
My $50 Stack vs. Enterprise Stack
I've worked at companies spending $50,000/month on tools. Their output wasn't proportionally better. Often it was worse because of the complexity overhead.
The lean stack wins for side businesses and small teams because:
- Less coordination overhead
- Faster decision making
- No vendor lock-in complexity
- More profit margin
- Focus on what matters (the work, not the tools)
Will this stack scale to 100 employees? No. Do you need it to? Almost certainly not.
Building the Habit of Lean
The hardest part isn't choosing cheap tools. It's resisting the constant pull to add more.
Every week brings new AI tools, new productivity apps, new "essential" services. The Twitter algorithm loves showing you tools you don't have. The natural tendency is accumulation.
Fight this. Before adding any tool, ask:
- What specific problem does this solve?
- How am I currently solving that problem?
- Is the current solution actually bad, or just not shiny?
- What's the total cost including learning curve and maintenance?
Most tools you "need" are solutions looking for problems. A lean stack isn't just cheaper - it's clearer. Fewer tools means fewer integrations to maintain, fewer subscriptions to track, fewer passwords to remember, and more time for actual work.
The One Investment That Matters
If I had to choose one tool to pay for, it would be Claude or ChatGPT. Not close.
AI assistance is a genuine multiplier on everything else. Better writing, faster research, smarter analysis, quicker debugging. The $20/month provides value equivalent to hundreds of dollars in other tools.
Everything else in the stack is negotiable. AI assistance is not. Start there, add cautiously, and you'll build something lean that actually works.
Getting Started This Week
- Sign up for Claude Pro ($20)
- Set up Notion (free)
- Register a domain ($12)
- Start building
That's it. Everything else can wait until you actually need it. Most of it you'll never need.
The businesses that win aren't the ones with the fanciest tools. They're the ones that ship, learn, and iterate. A lean stack supports that. An enterprise stack often impedes it.
