My service contract expired with them this Friday. Opted not to renew because of price change in synthetics product 100x initial release. The product is reliable, but billing is troubling.
We were using Synthetics during beta alongside Pingdom - doing pretty much the same on both. Beta period ended and sales rep said our Synthetics bill would be something crazy, like 10x our Pingdom bill, and it’d start next month (they later said that was a mistake and it would actually start in 2 months, when I pushed back).
We immediately suspended all our Synthetics tests. It’s nice having them with the rest of our Datadog stuff, but it’s not 10x better than Pingdom.
Datadog is still a great tool overall, but experiences like that make me wary of putting all our eggs in the DD basket and getting locked in.
