Developer Diagnostic Tools
Production diagnostic utilities developed by Vexn Engineering. Run scans against your domain, evaluate architecture bottlenecks, and benchmark systems before launch.
Available Diagnostics
Website Discoverability & AI Readiness Scanner
Audit your domain across crawler access rules, entity schema graphs, and content structure. Generates instant copy-paste code fixes for missing schemas, llms.txt, and crawler rules.
- ✓ 8-Bot AI crawler access detection in robots.txt (GPTBot, ClaudeBot, Gemini, Perplexity)
- ✓ llms.txt standard format and route validation
- ✓ Organization and Person Schema.org entity evaluation
- ✓ Brand name alignment across title, Open Graph, and JSON-LD
- ✓ Content extractability and rich schema verification
Engineering Tools Roadmap
Upcoming diagnostic and benchmarking calculators currently being built and tested.
PostgreSQL Connection Pool Sizer
Calculate max_connections, PgBouncer pool modes, and memory overhead for serverless deployments on Supabase, Neon, and AWS RDS.
- • Linux process-per-connection RAM calculations
- • Serverless burst concurrency models
- • Transaction vs Session pooling recommendations
Edge & Serverless Latency Profiler
Benchmark latency differences and edge overhead between Cloudflare Workers, Vercel Serverless, and AWS Lambda container cold starts.
- • Isolate startup latency benchmarks
- • Regional egress cost modeling
- • Cache hit ratio estimation
Need these architectural gaps fixed in your codebase?
Automated scanners identify the symptoms. Vexn writes the production code: connection pools, RLS policies, zero-trust auth, and edge routing.
