Every SaaS product ships with a promise. But beneath the surface, there's a layer most teams don't see until it's too late: security gaps that bypass your pentests, performance bottlenecks that only appear at scale, accessibility issues that silently exclude users, and hidden CVEs lurking in your dependency tree. These aren't edge cases. They're the invisible engineering debt that compounds daily.

TL;DR I run a small dev-shop. Every product I ship needs an LLM call somewhere — content generation, security analysis, classification, summaries. The economics only work if these calls average near-zero . The trick: never pay for what a free tier can do. Stack 5+ providers in a deterministic fallback chain so that when one rate-limits, account-bans, or hikes prices, the next one takes over within the same request — invisible to the user. This post is the actual production code from audit_routes.py powering askoracle.site/audit — a 12-question crypto security scan that costs me $0 per scan in practice, while still producing real AI reports anchored to 2024-25 incident cases. --- The fallback chain User request │ ▼ ┌──────────────────────────────────────────────────────────┐ │ Groq llama-3.3-70b (5 keys, sequential, free tier) │ Tier 1 └──────────────┬───────────────────────────────────────────┘ │ all 5 rate-limited / Cloudflare-blocked? ...
