$4.2k/mo from 3 micro-saas apps with zero API costs competitors pay $20-200/mo in openai and anthropic fees he runs local LLM inference at 716 tok/s and pays nothing same claude code workflow, same boring stack, completely different margins the video shows his setup - macbook with oMLX dashboard on one side, claude code terminal on the other. the stats are right there on screen: 2.4 million tokens processed, 95.1% cache hit rate, 716.3 tok/s inference speed. model running is gemma-4-2b quantized, eating 28GB of his 36GB memory this man turned a laptop into a production inference server the edge most indie hackers miss: everyone obsesses over the product, nobody optimizes the infrastructure. he found the arbitrage his build process is identical to the standard playbook. next.js, supabase, stripe, vercel. CLAUDE.md file with stack conventions. claude code handles development, writes clean code on first try the difference hits when the product goes live most micro-saas founders watch margins shrink as users scale. more customers means more API calls means more costs. some hit 30-40% of revenue just on inference his products: → competitor price tracker for shopify owners: 34 users × $29/mo = $986/mo → email subject line optimizer for newsletters: 52 users × $19/mo = $988/mo → customer support auto-responder for small stores: 89 users × $25/mo = $2,225/mo $4,199/mo total revenue API costs: $0 the workflow: development → claude code builds features, handles complex logic, one task at a time with specific prompts production → all LLM calls route to local inference via oMLX. 716 tokens per second, 95% cache hits, runs while he sleeps his competitors on the same products pay $150-400/mo in API fees. at scale some pay $1,000+ the breakeven math: a decent local setup pays for itself in 3-4 months. everything after that is pure margin advantage competitors need 50 users to cover costs he profits from user #1# the dashboard keeps counting tokens, the terminal keeps running, and every dollar after stripe fees goes straight to his pocket
