TLD stands for [top-level domain](https://en.wikipedia.org/wiki/Top-level_domain), but if you clicked this post, you already know that. To make this joke more accurate, I would need to say "I bought a [second-level domain](https://en.wikipedia.org/wiki/Second-level_domain)", but the amount of people who know what a SLD is is even smaller than the amount of people who know what a TLD is. Hence TLD in the title.

My point is, I bought a 4 letter domain that is reminiscent of a `.co.uk` or `.co.in`. It is, *\*drumroll\** [`o9.nz`](https://o9.nz). It costs me around 10 usd per year.

Now why would I do that?

Because the amount of mini projects I have created and am actively using exploded with coding agents. But I don't have the money, or patience to buy a new domain for each of them. I am not an exited cofounder who collects domains as a hobby (yet).

Theo Browne's [t3.gg](https://t3.gg) gave me the idea, but what convinced me was that I could use it as a dumping ground for my side projects without getting bankrupt.

## How I found the domain

You might realize a New Zealand `.nz` domain is not the first choice, when I could get `.gg`. The problem is that THEY ARE ALL TAKEN. Apparently most 4 letter domains are taken.

I knew I wanted it to start with `o` of `onur` and I wanted it to be a numeronym like t3 (= t(heo)).

I slopped a script to scan for available domains, [click here](https://github.com/osolmaz/onurpi/blob/main/packages/agents/skills/name-claim/scripts/check_two_letter_domains.py) to use it yourself.

With o3, literally everything was taken. My next choice was o9, from `o(nursolmaz)`. 2 were available: `o9.pe` and `o9.nz`. I decided against `.pe` for Freudian reasons, and also it looks better when none of the letters have descenders.

The keys for `o` and `9` are right on top of each other in QWERTY, which was another plus!

## Example

[unyolo](https://github.com/osolmaz/unyolo) is one of the projects I use whenever I run an agent that has the risk of getting prompt injected. For it, I had bought the domain [unyolo.io](https://unyolo.io) before.

But .io domains now cost 40-50 bucks a month. And I won't get an .io domain for every side project. So now it lives under [`unyolo.o9.nz`](https://unyolo.o9.nz).

## Email

Having a very short domain, I thought, how far can I push for maximum wtf effect?

Apparently RFC 5322 allows for `?` in email addresses like `?@o9.nz`.

But to my disappointment, Google workspace did not accept it. Neither does it accept `.@o9.nz`.

So I ended up choosing `9@o9.nz`. I will use this email whenever I don't want to give my real one 🤗

## Conclusion

Thank you New Zealand for hosting my vibeslop.
