I used Astro with DaisyUI and Cloudflare Workers/CDN to make the site fast and SEO-friendly. Managed to get a 100% Lighthouse score, which is nice. Overall, it went pretty well, though I did run into a couple of bugs with Astro along the way — some of which have already been fixed. It uses Gemini 3 Flash under the hood right now. I've also spent some time protecting it from bots and scrapers with Turnstile, and I currently manage my costs by pre-funding credits to avoid any surprises on my bills with post-payment, in case bad actors try to exploit the service (and while not user-friendly, since it's a free public service, I might also add some fingerprinting if there's a need down the road).
My main motivation was to improve SEO presence and drive traffic/funnel into my main product (posted about it here: https://news.ycombinator.com/item?id=46183195). But at the same time, I wanted to create something useful, so I ended up spending more time on that than I initially planned. I’m curious to see how it all turns out, how much it will cost, and how soon I might run out of credits.
