Show HN: I built the fastest VIN decoder

1 samsullivan 0 8/4/2025, 11:42:58 PM github.com ↗

Decodes any VIN in ~20ms with zero network calls. I compressed the entire NHTSA vehicle database into a 21MB SQLite file that runs completely offline.

No API keys, no rate limits, no servers. Just download once and decode forever. Works in browsers, Node.js, Cloudflare Workers - anywhere SQLite runs.

Would love any feedback and to answer any questions about the implementation.
