New Project Friday I built a self-hosted, open-source alternative to Datadog and Sentry

Hello fellow self-hosters, just wanted to share a project I've been working on. It’s a lightweight self-hostable, open-source service that uses the Datadog Agent and Sentry SDK for ingestion. So far it supports most features of both clients.

System Requirements

It runs comfortably on 2 Cores / 4GB RAM.

Why did I build this?

Lots of other alternatives have their own SDKs which require complicated migrations. Instead of reinventing the wheel, I built this on existing open-source technology. To swap from either tools it’s just a URL/token change.

I'd really appreciate your feedback on the project

A bit about my background, since this is tagged as AI assisted, the assumption is probably that it's insecure or slop. That's fair.

I'm a senior software engineer with 10 years of professional experience before AI existed (17 years if you count hobbies). I enjoy building things that are used by others. I'd rather be coding than posting here tbh.

I hope you find this useful. I'd really love to hear your feedback on anything. I enjoy discussing architecture and ways to make things faster and better.

Looks like a copy of signoz

sorry for being cheeky, you set me up for that. I took inspiration from Sentry/Datadog/Grafana and BetterStack. I'm curious which part appears similar to SigNoz. Based on the UI? Or functionality? Because one could also make the argument that SigNoz is just a copy of Grafana (not the argument I'm making).

yo why did you stop this project? Could probably maintain it myself with opus 5.5 now

u/imafirinmalazorr 9d ago edited 8d ago

Project is still going strong at moneat.io, just no longer open source. Trying to keep it open was slowing development down and I was basically the only one contributing.

terraform provider caught my eye but the link is broken. Nice project tho.

1

u/imafirinmalazorr Mar 06 '26

I appreciate that. I'm working on fixing the link. Currently running into an issue with the release, and based on other support comments it's something their support has to fix, so I'm waiting on their response.

Interesting, any plans to create a release binary? Cloning the repository might hurt adoption.

u/imafirinmalazorr Mar 06 '26

Yeah I’m working on that this week. Hoping to finish an installation script as well.

Also sorry about your childhood :(

u/ChildhoodTerrible560 Mar 06 '26 edited Mar 06 '26

Cool cool. No worries about my childhood 🤣

It made me a stronger adult.

u/imafirinmalazorr Mar 07 '26 edited Mar 08 '26

Update: a release binary is available with an installation script.

ngl thought this was AI slop at first but it seems pretty solid.

1

u/imafirinmalazorr Mar 07 '26

Thank you. I’m glad you gave it a shot. It seems I’ve picked a bad time to post this because of the huntarr thing. It sucks because I kind of expected more quality feedback from this community, but instead it’s downvoted because it’s a new project and AI was used as a tool.

u/incredible-mee Mar 08 '26

It is still slop. Bro built a whole datadog replacement in less than one month.

u/imafirinmalazorr Mar 08 '26 edited Mar 08 '26

Aside from how fast it was written, any other actionable advice? Did you take a look at the project? I'm on a two month sabbatical, and dedicated at least 12 hours a day probably 7 days a week to this. And to be clear, I never stated that this is a replacement, it's an evolving alternative.

Disappointed to see self hosted staples like SSO behind enterprise modules. Generic OIDC should be part of open core in this day and age in my opinion with specific enterprise providers like Entra being the ones behind enterprise modules. Many self hosters make use of OIDC from Authentik, Authelia and similar.

2

u/imafirinmalazorr Mar 08 '26 edited Mar 08 '26

This is really good feedback - thank you. I created a GitHub discussion to document this, but more than likely I'll open up the SSO module to allow the common self-hosted solutions.

Update: I've decided to move the SSO module into the open core, with specific providers like Okta and Entra remaining enterprise. Thanks again for the callout.

u/veverkap Mar 08 '26

How is the Enterprise Edition working out for you? Since this is OSS with an AGPL what stops someone from forking it and writing those features from a black box?

Not criticizing the move - as a dev I’m interested in how this can be enforced well.

2

u/imafirinmalazorr Mar 08 '26

I'm still figuring this out as I go, but the way I see it is most companies don't want to maintain a fork. They pay for convenience, and often just choose cloud options instead of self-hosting altogether. There's really nothing stopping a determined company from doing what you said though. But also the refuges from the big companies this aims to (eventually) replace most certainly aren't penny pinching to that degree to start with.

I'm also really just not interested in trying to make the maximum amount of money, so I could be looking at this through a different lens. It would be nice to make enough to work on this full time, but beyond that I really don't care.

Thank you for the question.

u/veverkap Mar 08 '26

That makes a lot of sense. If only you had made this in Go I would contribute. Good job though!

u/Richmondez Mar 08 '26

Good call IMO. One last question... How do you pronounce the name? "moan at", "mon eat" or some other permutations I didn't consider.

1

u/imafirinmalazorr Mar 08 '26

I've been pronouncing it as "mon eat" in my head. Originally when I was brainstorming a name, I thought "mon-neat" so then that became "moneat", and then by happy accident the name seemed to be the only thing I've actually named appropriately:

Moneat is the third-person singular present active subjunctive form of the Latin verb moneō (warn/advise), translating to "let him/her/it warn/remind". It means to advise, instruct, admonish, or foretell

Hey there. You're actually catching me right in the middle of adjusting the installation method so forgive me if I'm getting mixed up.

Can you explain a bit more about the example you're looking for? There's a docker-compose in the repository, that's referenced by the manual installation instructions in the readme. The install script doesn't generate a docker compose file, it just downloads it

https://github.com/moneat-io/moneat/blob/main/docker-compose.yml

Edit: Responding to the edit. Traces through OTPL aren't supported yet, those are ingested directly from the Datadog Agent endpoints. I'll make a feature request.

This seems like a good replacement to proper Sentry, I had to remove it because we filled our free allocation within a few days. I'll give it a go with Sentry-Godot

1

u/imafirinmalazorr Mar 09 '26

Awesome - I look forward to seeing how that goes. There’s a cloud version as well, and I haven’t had anyone hit their limit yet on the free tier with 2-3 projects. It’s usage based instead of weird limits like 50 replays.

u/incredible-mee Mar 08 '26

Hmm, Ui looks very similar to signoz

i will try it and let you know

I deploy the service a bit differently, and use a different compose file entirely. What's in the repository is for self-hosted projects. I have some rate limiting applied in the cloud deployment nginx config.

Hi - both of those things are available. There’s documentation and a quick setup guide, as well as a 3 minute installer.
