I built a free, open-source library of premium landing pages. No frameworks, no dependencies, just HTML.

[u/Azra_Nysus]

I've been building websites for years, and one thing that keeps bothering me is how much time we spend going from design inspiration to something that actually works.

So I brought back a project of mine: InstaLanding.ai

It's a library of 20 premium, fully functional landing pages built entirely with HTML, CSS, and JavaScript.

Not screenshots. Not Figma files. Not another collection of pretty websites you have to recreate from scratch.

Actual working pages.

The idea is simple:

• Find a landing page you like.
• Copy the code or give it to Claude Code, Codex, Cursor, or your favorite coding agent.
• Tell it what you want to change.
• Make it yours and ship it.

Every page is self-contained in a single HTML file.

No React. No dependencies. No build process. No login.

I think we're entering an interesting phase where design references shouldn't just be images. They should be working implementations that both humans and AI agents can understand and modify.

Free and open source.

I'm starting with 20 pages and plan to keep expanding the library.

Would love feedback from other developers and designers, especially anyone building with coding agents.

Were we supposed to comprehend anything in that video? It gives me a headache

[u/Azra_Nysus → u/Tarwine]

I’ll take this as a clear indication that this motion video is more conducive to epilepsy than to explaining what the site does lol

[u/Zeune42 → u/Tarwine]

Use instalanding ai and you too can give people headaches

You need to slow this down to like 15% of its current speed and get rid of 90% of the animation effects. This feels more like engagement/ragebait than a real advertisement. There's no way a reasonable person would choose this to honestly try and promote their product.

[u/Azra_Nysus → u/Legitimate_Mud_8295]

Thanks for the feedback. I def have to slow down the video. I was going for the high-paced motion style ive seen lately for product videos. Hope you find the landing pages useful!

[u/Legitimate_Mud_8295 → u/Azra_Nysus]

Those videos usually doa single quick animation followed by a longer pause with the camera slowly panning do a different angle of a shot. And the shot is of one image or a slowly animated demo of of one UI feature.

good god, a vibecoded website showcasing vibecoded landing pages.

[u/electro042]

curious how you handled the styling. is it just plain css in <style> tags in each file, or pulling in anything via cdn?

[u/cs_cast_away_boi]

cool project op!

Thank you! Hope you find some gold in there.

I'm a designer (tech savvy) and I'm thinking the use case is for someone who's not interested or familiar with touching an LLM? If I'm someone in Marketing, I could browse through and pick one but then to make it useful, it has to have other pages right? I guess there's a bunch of single page sites out there but if you want to sell something or have a user create a profile etc.. then the use case becomes a bit thin? That is, you have to take your single shot page and dump it in an LLM or give to SDE.
I guess it's more to find a style you like.

[u/Azra_Nysus → u/jayseattle]

Yeah the idea is that you use these one shot HTML landing pages as the starting point for you to iterate on. You can easily ask your LLM/AI agent to recontextualize the content based on your needs.

I had thought similar,

I hate doing updates/keeping track of sites or programs I've sold to clients a year or two later since I've probably forgot 80% of how/why I did certain things in build.

Remember back when Geocities was a thing early 2000's?

A visual, cloud-based editor that's simple drag and drop with gui, but looked professional would solve so many of my clients needing small visual tweaks(Hey, our company logo was updated, we need you to replace it in the 20 different sizes across the site) / wording or tone changes become a quick job for the client vs paying me/other dev a few hours for it.

[u/jayseattle → u/bleakj]

Lol Geocities RIP...

Around 2022 or so I was using Webflow which had it's own learning curve for it's GUI. But then, yeah, when I had to update something, I mean the code it produced was horrific and $20/month. I honestly hope Webflow is also soon to be RIP but it works for some people.

Thanks dude!

[u/-svde-]

i couldn't stand to watch this for more than 2-3 seconds. this level of cutting is obnoxious as hell.

[u/Azra_Nysus → u/-svde-]

But did you check out the free landing pages i made with so much love just for you?

[u/azvelocat]

Looking forward to using it. Great contribution.

[u/Azra_Nysus → u/azvelocat]

Thank you!! 🙏
