We built our entire AI App Builder on Cloudflare stack, and it's awesome

Hacker News - Wed, 04/16/2025 - 7:41am

Hey everyone, the founder of Fine.dev here.

I wanted to share my experience from switching our cloud provider to CloudFlare. A bit about us:

Last week launched our platform: An all-in-one AI that turns a single prompt into a production-ready app.

Every project our users build comes with auth, database, file storage, LLM integration, and hosting, all working out of the box.

It feels like magic but it's very real - and a lot of it is thanks to Cloudflare.

Our dream with Fine was that anyone, literally anyone, will be able to build and launch something useful. Without wrestling with infrastructure. Without stitching together 10 different services. Without spending weeks before seeing something live.

Cloudflare made that dream feel possible! It is global by default and fast by default. The Infra just "disappears" behind the product. This allowed us to focus all of our energy on our users' experience.

I mentioned the features before because each one of them relies entirely on Cloudflare's powerful stack: → D1 as the database → Workers for backend logic → R2 for file storage → AI Gateway for model routing

We are already having users testing this and the responses have been… incredible.

We’ve seen people ship AI agents, micro-SaaS apps, internal tools and personal productivity tools - everything that you can possibly imagine!

Despite all these different use cases, working with the infrastructure was smooth as butter. Really, one of the best infra experiences I had.

It’s been a joy building this.

A huge shoutout to CF team - we couldn’t have done it without the foundation you’ve built.

Show HN: Maps Can Lie. Earth Doesn't – See How Flights Travel

Hacker News - Wed, 04/16/2025 - 6:52am

I built a tool showing the dramatic difference between flight paths on traditional flat maps versus their true trajectories on a 3D globe. Maps Can Lie. Earth Doesn't. This visualization reveals how our mental model of air travel routes is often distorted by map projections, and helps users understand the actual paths planes take around our planet.

Ask HN: Should every country have their own national CA certs?

Hacker News - Wed, 04/16/2025 - 6:51am

We have so many regulations that force companies to store their customers’ data within the country, which makes sense from a perspective of privacy and security.

How do you feel about having a national CA certificate in every country?

How would someone feel living in authoritarian governments, knowing that the government can easily intercept and read many things?

How would a country feel that all the data of its people can be decrypted by another company? (most of the CAs are in the USA)

Ask HN: How does Cursor make money? Please ELI5

Hacker News - Wed, 04/16/2025 - 6:38am

Cursor's Pro plan offers 500 "fast" GPT-4 level requests + unlimited "slow" requests for $20/month. I'm struggling to see how this is sustainable given LLM API costs.

A rough estimate for just the 500 fast requests:

Assume ~1,200 tokens/request (modest input/output). Total: 500 * 1,200 = 600,000 tokens/month.

Using even cheaper modern models like GPT-4o (~5/15 per M tokens), this is ~5/month. Using older GPT-4 models (30/60 per M) would push costs well over 20.

This basic calculation doesn't include: The cost of unlimited slow requests, Infrastructure, overhead, R&D, Longer context usage typical in coding.

How can Cursor offer this at $20/month? What's the likely strategy here? Seems like the raw API costs alone could easily approach or exceed the subscription fee for many users. What am I missing?

I just wanted to share this free tool that I've made that will generate you sprint name ideas based off of an input. It's been a fun little ceremony our team enjoys. Generating a name at the start. Worth a couple of laughs
