Show HN: Forced to build my own Harvest alternative tracking and invoicing

Over the years I've tried dozens of time tracking and invoicing apps, and Harvest was the only one I liked. Primarily due to its relatively intuitive UI/UX.

I was happy to pay them a reasonable sum for the product they provide, but after the 10x price jack, I had no choice but to seek alternatives. I tried a bunch of them again, found nothing I liked.

So, with 20+ years of software engineering experience under my belt, I decided to build my own.

Here's the result: https://hourbun.com/

I first and foremost built it for my own use, then over the past week or two added features that others might need (such as approvals, quotes, expenses, etc).

I spent a lot of time making sure the UI/UX is top-notch, and the performance is even better than Harvest - the app should feel very snappy (it's hosted in the US, and I'm based in Australia, and it's still very fast for me).

If you're looking for a decent time tracking and invoicing app, give mine a try? It comes with a 14-day trial and doesn't need card details.

And in case you're wondering, no, it's not vibe-coded. AI agents were definitely a big part of building it, but the product was built with experience and care. Love to hear your thoughts and feedback.
