Hi Product Hunt! Maker of NerdKit here.
I built NerdKit (https://global-utils.com) because debugging production artifacts—like PostgreSQL EXPLAIN JSON plans, customer .parquet files, WebAuthn CBOR attestations, or .har logs with session cookies—on ad-heavy server-backed websites violated strict data-privacy rules.
Every one of NerdKit's 60+ utilities runs 100% inside local browser RAM (open DevTools Network tab while dropping any file—0 bytes are uploaded).
Highlights:
• LLM GPU VRAM & Cloud Cost Calculator (GGUF block scales + GQA vs. DeepSeek MLA 576-dim KV cache math — MIT CLI: https://github.com/JangYS0/llm-v...)
• PostgreSQL EXPLAIN ANALYZE Flamegraph Visualizer (MIT CLI: https://github.com/JangYS0/pg-ex...)
• In-Memory Apache Parquet & SQLite Viewer (tail-first Thrift footer binary slicing)
• MCP (mcp.json) Config Builder, Secret Masker & HAR Credential Redactor
Would love your honest feedback—which binary or log format should we add next?
