Now YC has funded 4 companies directly competing with each other.

https://news.ycombinator.com/item?id=25991485 Launch HN: Opstrace (YC S19) – open-source Datadog

https://news.ycombinator.com/item?id=22376732 Launch HN: PostHog (YC W20) – open-source product analytics

https://news.ycombinator.com/item?id=26079389 Launch HN: SigNoz (YC W21) – Open-source alternative to DataDog

https://news.ycombinator.com/item?id=36774611 Launch HN: Highlight.io (YC W23) – Open-source, full stack web app monitoring

The monitoring space is heating up after the Datadog IPO.

Edit 2023-07-18T22:42:00Z: added PostHog

Opstrace was acquired by GitLab soon after launch. And signoz, in our minds is more leaning towards Grafana/Prometheus (and not particularly web app oriented).

I’m personally excited by the fact that there are other players in the space. It pushes us to move quickly and stay focused.

And I agree with your analysis, Datadog has proven that there’s a huge (and only growing) market for observability tooling.

Good take on the competition, and I'm looking forward to trying out Highlight.io.

Excited for you to give it a try.

I would say the key way we differ from Grafana stack, is that we have all metrics, traces and logs in a single application while in grafana you would have to run 2 different products for this and then work your way to make sure that the three products are able to talk to each other.

One can easily monitor their JS based frontend application in SigNoz today, but yes we are focused primarily on tying together metrics, traces and logs today - and have a pretty powerful exceptions monitoring product built on top of traces.

We don't do things like session recording etc today :)

Interesting fact - all four are using ClickHouse, which is my favorite technology.

I find that clickhouse is absurdly fast for massive amounts of small items. Since that’s what all of these are, it’s not super surprising.

Clickhouse is insanely good for OLAP type data. But I've found it flexible enough to even be a suitable substitute to time series data.

One more thing to add here given your edit. Posthog does not directly compete with us. They have a session replay product; that is the only overlap. Nonetheless, their work on session replay (and in turn, with rrweb) is making the ecosystem better overall.

Agree, I think PostHog adresses a very different set of use cases

On top of indiehacker tools like fathom, plausible, etc. Market is huge

https://openreplay.com is also great. Has helped us detect issues in our US as well as trace graphql requests.
