Thank you! With respect to datadog the elephant in the room is cardinality and pricing. We charge $20/mo and based on usage of data storage and query execution time. DD is notorious for charging for metric cardinality, which can very easily blow up. Coinbase famously racked up a $50m bill from this!

With respect to the product, we believe there's a segment of the market that likes to know what they are measuring. Datadog and other "telemetry" tools often times install an agent and collect metrics automatically. While this is a great UX onboarding, it does make it harder to know what data you have and how to query it. Whereas with telemetry we believe having that "manual shift" mode where you log your own data and write your own queries is useful in many scenarios.

I'd love to chat more if you're up for it! Shoot me an email at hi@telemetry.sh if you're open to the idea.
