I Spent $847 Building the Same App Three Times So You Do Not Have To
Everyone has an opinion about AI coding tools. Nobody has receipts. I built the same full-stack SaaS application – a client dashboard with authentication, Stripe billing, and a real-time analytics view – using Claude Code, Cursor, and GitHub Copilot. Here is exactly what happened.
The Test Setup
Same spec. Same deadline. Same developer (me). Three tools, three builds, three invoices.
- App: Client analytics dashboard (Next.js + Supabase + Stripe)
- Complexity: Auth, billing, real-time data, admin panel – roughly 4,000 lines of code
- Timeframe: Built each version over one weekend
Claude Code (Anthropic) – The Architect
Cost: $200/month (Max plan) – used ~$45 worth of tokens for this project
Time to complete: 6.5 hours
Lines of code generated: ~3,800 (95% of total)
Claude Code understood the full project structure from the start. I described the dashboard in plain English, and it scaffolded the entire app – auth flows, database schema, API routes, and frontend components. The Stripe integration worked on the first try.
Strengths: System-level thinking, rarely makes mistakes that break other parts of the codebase, excellent at refactoring
Weaknesses: Slower output speed, the $200/month price tag is steep for hobbyists, CLI-only interface takes getting used to
Cursor – The Speed Demon
Cost: $20/month (Pro plan) – no additional token costs
Time to complete: 8 hours
Lines of code generated: ~3,200 (80% of total)
Cursor is fast. Autocomplete is genuinely magical – it predicts multi-line blocks with scary accuracy. The inline chat for quick fixes is excellent. But for complex, multi-file changes, I had to guide it more carefully.
Strengths: Best autocomplete in the business, smooth IDE integration, great for iterative coding
Weaknesses: Struggles with large refactors across multiple files, sometimes generates code that conflicts with existing patterns, context window feels smaller in practice
GitHub Copilot – The Reliable Workhorse
Cost: $19/month (Individual plan)
Time to complete: 11 hours
Lines of code generated: ~2,600 (65% of total)
Copilot is the tool that does not try to impress you. It just works, consistently. Autocomplete is good (not as good as Cursor). The chat feature is competent but not as capable as Claude for complex reasoning.
Strengths: Most stable, best GitHub integration, lowest learning curve, works in any IDE
Weaknesses: Generates more boilerplate, less creative problem-solving, chat mode is noticeably weaker than competitors
The Verdict: Which One Should You Use?
| Category | Claude Code | Cursor | Copilot |
|---|---|---|---|
| Speed | 6.5 hrs | 8 hrs | 11 hrs |
| Code Quality | 9/10 | 8/10 | 7/10 |
| Cost | $200/mo | $20/mo | $19/mo |
| Learning Curve | Steep | Medium | Easy |
| Best For | Greenfield projects | Daily coding | Everyone |
If money is no object: Claude Code. It finished fastest, produced the cleanest code, and required the least debugging. The $200/month pays for itself if you build production apps.
If you want the best value: Cursor at $20/month. Nearly as capable for 10% of the price. The autocomplete alone saves hours per week.
If you want zero friction: GitHub Copilot. It works everywhere, breaks nothing, and quietly makes you 30-40% faster without changing your workflow.
The real answer? I use all three. Claude Code for new projects and complex refactors. Cursor for daily coding. Copilot as a fallback in environments where Cursor is not available.
The AI coding tool wars are far from over – but right now, in April 2026, these are the three that actually matter.
