Tools I have actually shipped with.
Every comparison here is between two things I have run in production, usually at the same time. That means I can tell you where each one breaks, which is the part a feature table never covers.
Pick one.
- MCP vs Function Calling What MCP adds over plain tool calls, and when the extra moving part is not worth it. AI AGENTS
- Supabase vs Firebase Ten shipped products on Supabase. The Postgres argument, and the places Firebase is still the faster call. BACKEND
- Vercel vs Railway Both run production apps here. Where the serverless model helps, and where it quietly bites. HOSTING
- Astro vs Next.js This site is Astro. A client app is Next. How to pick without relitigating it every project. FRAMEWORKS
- Lovable vs Replit vs Bolt Where all three get you in an afternoon, and the exact point each one stops. AI BUILDERS
- OpenRouter vs Calling the API Direct Five models across live products. What the router buys you and what it costs. LLM OPS
- Resend vs Mailgun I moved a production CRM to Mailgun and hit a deliverability trap that has nothing to do with either product. How to pick, and what to check before you switch. EMAIL
- GoHighLevel vs HubSpot Client work in both. Which one fits an agency, which fits a sales team, and the migration cost nobody mentions. CRM
- AI SDR vs Hiring an SDR I built a working sales agent. Honest read on what it replaced and what it absolutely did not. SALES
- Custom CRM vs GoHighLevel I used GHL for years, then built my own. The three conditions that justify building. CRM
- Claude vs GPT for Coding Both run daily against real repositories. Where each is stronger, measured on actual tasks. AI CODING
- Firecrawl vs Apify vs Puppeteer All three are in my stack for different jobs. A decision tree instead of a winner. SCRAPING
- Row-Level Security vs App-Layer Auth RLS shipped on several products, including the mistakes. Why the database is usually the right place. SECURITY
- Supabase Edge Functions vs Vercel Functions 98 edge functions on one product. Where each runtime belongs and how they fail differently. BACKEND
- AI Phone Agent vs Chatbot vs Live Chat Shipped a roofing voice agent. Which channel actually books the job, by lead type. AI AGENTS
- Zapier AI vs n8n AI Agents 20+ workflows across both. Where the managed version saves you and where it traps you. AUTOMATION
- Twilio vs WhatsApp Business API Both wired into live products. Deliverability, cost, and the template approval reality. MESSAGING
- Stripe Checkout vs Payment Links Live billing on both. The fastest path to a first paid customer, and when to upgrade. PAYMENTS
- Shopify vs Custom Ecommerce Client builds on both. The revenue point where custom starts to pay for itself. ECOMMERCE
- WordPress vs Astro I have migrated sites off WordPress. What you gain, what you give up, who should not move. WEBSITES
- n8n vs Make: The Deep Cut Past the feature table, into error handling, versioning, and what breaks at scale. AUTOMATION
Earlier comparisons.
- n8n vs Zapier vs Make 20+ shipped workflows across all three. How they differ and how to pick. AUTOMATION
- AI Phone Agent vs Answering Service What each actually does with an after-hours call, and what it costs. VOICE
- Lovable and Replit vs Hiring a Builder Where the AI builders get you, and the point they stop. AI BUILDERS
