Show HN: An open-source notification infrastructure

[opensh]

There are some nice bits of the software that aren't open source: Single Sign-On (SSO) integration, Auditing logs, etc.

Thanks for the heads up.

I've come across Novu in the past and it looks like a solid piece of software. The need to bring MongoDB into my stack is a deal breaker though. Anyone aware of something similar that works on a Postgres database?

[amne → Rodeoclash]

maybe you can use ferret?

https://www.ferretdb.com/

[redhale → amne]

I'm not GP, but Ferret looks cool, thanks for sharing!

[tomerbarnea → amne]

ohhhh, exciting solution. I wonder if they have a 1:1 interface... Did you try it? Did you try setting indices?

[maxloh → tomerbarnea]

It is a long way to go. Check the counts of "Unexpectedly failed" and "Expectedly failed" tests in their integration testing logs [0].

Also, take a look at the "Known differences" section in their documentation [1].

Why MongoDB is a deal breaker?

[thangngoc89 → opensh]

Because MongoDB's license change disallowed cloud service provider to host MongoDB. This reduces the competition and *probably* making MongoDB more expensive than says PostgreSQL. Which I can find a hosted solution anywhere I host my VPS.

[dev005 → thangngoc89]

There are a few alternatives to Novu - Courier, Knock, Engagespot, SuprSend

> a hosted solution anywhere I host my VPS

Wait what? Hosted or you host on your VPS there is a major difference.

Or do you mean you host yourself now and want to be able to move to a hosted solution (or the other way around)

[Oras → thangngoc89]

Aws documentDB is compatible with MongoDB

[maxloh → Oras]

It is compatible with MongoDB v4.0 only. The latest version is 6.0.7.

[winrid → maxloh]

You're a ~years out of date on both numbers :P

[redwood → thangngoc89]

That is not an accurate interpretation of the SSPL. You can build any software you want on top of it... the key is you can't deliver it itself as a public cloud service, that's all

[from-nibly → redwood]

That's what they were saying. They are saying that aws not being able to offer a hosted version is the bad thing they don't like.

[mikasisiki]

Why not available in C# :(

[neonsunset → mikasisiki]

They do have a .NET sdk but it's implemented incorrectly (incompatible with AOT, does not use System.Text.Json, etc.)

[speq]

https://ntfy.sh/ is also worth mentioning in this space.

[jeroenhd → speq]

I think https://unifiedpush.org/ is more directly related to a full client/server system like this.

With the right API wrappers, existing UnifiedPush clients and servers can be used with Novu UnifiedPush, as UnifiedPush can work over all manner of transports with the right connectors in place.

[moonsu → speq]

There’s also https://www.notificationapi.com/ as a non free option

[opensh → speq]

Ntfy is more like a tool to aggregate notifications for recipients themselves right? Novu is like a backend as a service for notifications.

[axelthegerman → opensh]

Yea I was wondering about this myself actually... I'm building a SaaS and wanted to add notifications - without building my own app. But now my customers would still have to install the Ntfy app, which then could be used for notifications from other services as well.

But yea maybe it's more for geeks who want to send notifications from many places and receive them in a single app
