Healthchecks VS AdGuardHome

In fact, your platform (https://healthchecks.io/) is a prime example of where running customer wasm would be really excellent.

Instead of sending webhooks out to customer configured URLs, you could run a Wasm environment to execute customer code. Off hand, a good use case here is to do further inspection of the event before it gets sent off to some other system - maybe there are cases where you send false-positives and needlessly trigger external system alerts. The customer Wasm could do more introspection on the healthcheck event and make a more informed decision about how to proceed.

i use healthchecks.io and have been very happy

Is there anything different from https://healthchecks.io/ --- a service I've been using for free for a couple years now?

Because of this block on the router, and the fact that IPv6 connections are by default preferred over IPv4, many things on the system now cannot access the internet. the only things that can access the internet are for accessing servers that ONLY support IPv4 like my mail.smpt2go or my uptime monitoring scripts for healthchecks.io.

i use https://healthchecks.io/ and highly recommend it.

We use a heartbeat system. Basically the monitoring continuously sends an alert to a healtcheck system. If that heartbeat fails, PagerDuty sends an alert to the oncall.

i like healthchecks.io

There are some good (free!) monitors out there, I have used and like healthchecks.io and cronitor.io

Also AdGuardhome will use optimistic caching, which is great.

The main repo is GPLv3: https://github.com/AdguardTeam/AdGuardHome

They already have many other commercials products and I guess also the default filter rules are very good because of their experience in the domain.

But I think you can use it completely without the AdGuard servers and use other filter list sources.

How it compares to let's say AdGuard Home? Seems similar https://github.com/AdguardTeam/AdGuardHome

I'm using adguardhome v0.107.42 openwrt snapshot on linksys wrt1900ac v2, but when using DoH it won't resolve upstream DNS, but DoT is works perfectly OK, I've already set allow_unencrypted_doh to true in config .yaml file as per instruction here

AdGuard Home?

Regarding open source, AdGuard DNS actually is:
