I built a zero-backend CDN for hotlinking SVGs. Unlimited bandwidth.

https://svg.inbondz.com

I was tired of copying and pasting SVGs over and over again for my projects and social links. So I built that. Tell me if you need any other SVGs.

Not me but good friend of mine is building https://onepilotapp.com , genuinely looking for it going live.. me I m testing SEO, unsuccessfuly so far ^^
wasimsk•1h ago
Mhm. Great!

Btw. Nice to meet you.

So what did you learn in SEO? I generally don't have much knowledge about it.

elmlabs•1h ago
Litteraly started 2 days ago ahaha, I spent a lot of time building things but never making them visible, so far I got nice results on the news aggregators feeds. I ll not try so hard in it, I still think bringing genuine interest about a topic is a more respectful way of doing
wasimsk•1h ago
I got it. Are you a developer? Have GitHub? X or something?

I am working on https://spatialsheets.com Think geodata formulas + excel. Mostly for my own use just to quickly debug geodata. Used to heavily use geojson.io for it but it is not very good at handling large datasets and couldn't enrich data so I started working on this thing.

It's a CLI tool. It plays well with AI but it works great without it.

I'm working on https://suggestionboard.io, a simple live polling and Q&A webapp that doesn't require an account. Just launched the first version and trying to figure out if there's a market.

I’m building DataJelly.com — a visibility layer for AI-built and JS-heavy sites.

A lot of tools like Lovable and Bolt generate apps that look great but don’t expose content well to search or AI crawlers. The impact is lower search ranking, fewer AI citations, and broken social links.

We fix all of that by returning fully rendered HTML to SEO bots and clean Markdown to AI crawlers so they can actually understand the content. We also fix the Social Sharing broken links with custom HTML generated just for sharing your links on social.

Quick setup, no code required.

Free: visibility test: https://datajelly.com/#visibility-test Our Edge Product: https://datajelly.com/products/edge

Happy to answer questions.

I'm building free immigration software for DIY applicants [1]

It's a free USCIS form-filling web-app(no Adobe required). USCIS forms still use XFA PDFs, which don’t let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.

So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.

I found out SimpleCitizen(YC S16) offers a DIY plan for $529 [2]

So, a free (and local-only) version might be a good alternative
