Since I needed it to be my primary DNS, I also added: recursive resolution from root nameservers, DNSSEC chain-of-trust validation, ad blocking (385K+ domains), and LAN service discovery.
Very interesting project! I have a couple of questions. With all the default blocked domains loaded, what is the average memory usage? Currently, I am using Pi-hole on a low memory single board computer. Is it possible to use this instead of Pi-hole? If so, I’d like to use it for all of my devices."

With 390K blocked domains: ~31MB total process footprint.
Breakdown:
- Blocklist: 23.4MB (390K domains)
- Cache: 3.8MB (4.4K entries)
- Query log, SRTT, runtime: ~4MB
It binds to 0.0.0.0:53 by default, so just point your devices' DNS to the board's IP

Thanks! If you hit any issues during setup, feel free to open an issue — happy to help debug. The dashboard at localhost:5380 shows what's happening in real time.

It's neither here nor there but can I ask about the name? I only ask because when I see "numa" in relation to computing I immediately think "Non-Uniform Memory Access".
Very cool project by the way. I wonder how this would run on an OpenWRT device.
I see in your install.sh that you support Linux and Darwin/MacOS, do you think there would be any major hurdles in supporting FreeBSD?
On OpenWRT — it's musl-based Linux so the binary should run the arm one would need a crosscompile
Free BSD can be done (pr's welcome?)

Nice idea. To test I ran a simple nextjs on port 3000. Added the service via the dashboard.
However, when I visit the url, (using chrome latest version), https://{mygivenname}.numa/ I hit a DNS resolution fail error.
If I do not use a trailing '/' then it is going to google search for {mygivenname}.numa and shows me some search results. Should I open an issue?
rdme 3 hours ago [-]
Is it possible you didn't start it as root ( sudo numa install)?
Does dig {mygivenname}.numa @127.0.0.1 return 127.0.0.1 ?
What OS are you on?
Maybe you report it as an issue?
p2hari 3 hours ago [-]
Thanks for quick response. It started to work. I think it must be some caching issue. But it needs a trailing '/' . Maybe will raise the issue for this. Cool.

I believe that is actually browser specific behavior. I sometimes use a fake TLD for stuff hosted at home, and both chrome and firefox resort to search if I don't include a trailing '/'. My assumption is the browser does a quick match against known TLDs and if it doesn't match then it resorts to search.
rdme 2 hours ago [-]
exactly, I'll add a pr soon that tells the os (and browsers) that is'a a valid domain

The interface looks vibecoded. I have no problem with people vibecoding things. In fact, I have zero frontend skills, so I rely on AI to be able to make easy-to-use interfaces. However, I feel like this should be clearly and prominently displayed in the project page.
Furthermore it is a little off-putting to see a vibecoded UI because I have very little confidence that the rest of the backend code is not vibecoded. I know I am possibly being unfair, but this is how it looks to me. If the developer tells me they didn't use AI at all, I would believe it.
andoando 47 minutes ago [-]
I dont get this criticism at all, would you prefer someone write a shittier UI? And since when were people writing amazing bug free software before hand where not being vibe coded meant you could trust its good software?
I guess to be fair, beforehand no body would be attempting this kind of thing and releasing it unless they knew what they were doing

It definitely is and you can see it in the git commits. The DNS wire protocol parser was the original learning project I wrote to understand the spec. Later features (recursive resolver, DNSSEC validation, the dashboard) were built with the help of AI

Given the state of webdev it is not a surprise. LLMs are my rubber gloves when working with web technologies.

How is to compare to AdGuard? If it gets those features I would be switching over.
rdme 32 minutes ago [-]
Numa can do recursive resolution from root nameservers + DNSSEC, .numa local domains with auto HTTPS for dev, and LAN service discovery.
What features would you be interested in?

Same hack here ; I have no DSN running by default - much more handy than having to set up nginx as it has no opinion on the targeted infrastructure. And the bonus point is that you can see every sneaky request that happens when you browse ; so another side-project connected to this is to make an inventory and policy filter
rdme 4 hours ago [-]
Yes sir!
The query log is at GET /querylog (or on the dashboard) shows every request with domain, type, path (forwarded/recursive/cached/blocked) and latency
arafeq 3 hours ago [-]
this is really clean. the auto-TLS for local dev is the killer feature imo, so many hours wasted fighting mkcert and nginx configs. do you plan to support docker/container networking? being able to resolve service names across docker compose setups would make this a no-brainer for teams.

I don't want to hijack the thread, because that's a cool project.
Still, if you're looking for something that "just works" and is widely used, have a look at caddy.
rdme 3 hours ago [-]
Actually, if you point a container's DNS at the host (dns: [host.docker.internal] in compose), it works for resolution + ad blocking for the reverse however, I've added it on the radar, thanks!

How does auto-TLS work? It makes a self signed certificate automatically?
rdme 2 hours ago [-]
Yes — numa install generates a local CA and stores it in the system trust store. When you register a .numa service, it generates a per-service TLS cert signed by that CA

feature request: libnuma so i can use it programmatically with configuration. also, multiple user defined blocklists.
Cool idea, every developer running apps in dev on their machine knows this pain for sure. I'll give it a spin and let you know how it goes!

very interesting. how does the blocklist work? can one manage the lists? like StevenBlack or others.
I wrote about the DNSSEC implementation here: https://numa.rs/blog/posts/dnssec-from-scratch.html It's now my daily system DNS. Single binary (~8MB), macOS/Linux/Windows.
`sudo numa install`
It binds to 0.0.0.0:53 by default, so just point your devices' DNS to the board's IP

There's also a per-domain allowlist and you can pause/unpause blocking from the dashboard or API.
Here's how the resolution pipeline looks like: https://numa.rs/blog/posts/dns-from-scratch.html#the-resolut...
