Hello DEV Community! 👋
I want to share a project I've been building: an ultra-fast Web Metadata, OpenGraph & Contact Extractor API.
Here is the interesting part: 100% of the code, architecture, optimizations, and benchmarks were engineered in partnership with Gemini AI (Antigravity).
Initially, heavy web scraping took up to 23+ seconds on bloated websites. Working together with Gemini AI, we refactored and optimized the entire backend step-by-step to achieve enterprise-grade performance under 200ms (and 0.05ms on cache hits!).
Here is how Gemini AI brought response times down by 99%:
selectolax
)selectolax
(written in C based on Lexbor engine), dropping DOM parsing times from 15ms to httpx
with native HTTP/2 multiplexing and stream capping at 256KB to retrieve <head>
tags instantly without down 20MB of unnecessary assets.<script>
, <style>
, and <code>
tags before running regexes to prevent email false positives (like you@domain.com
in JS templates).I opened a free tier of 100 requests/month on RapidAPI so the community can use it for side-projects, lead enrichment, or link preview cards:
Working with Gemini AI to build this API showed me how fast we can take an idea from zero to a production-ready, monetization-capable SaaS.
I’d love to get your feedback, suggestions, or feature requests! What do you think about AI-driven API development? Let me know in the comments below!
