Compared a few options

Evaluated this against two competitors. Where it wins: the onboarding and it saves real time. Where it lags: a few rough edges remain. On balance the feature set — especially the API — justifies the 4 stars for our use case.

Years in this space

I've evaluated a lot of these over the years. What stands out here is the automation — handled better than most — and the value for money is strong. Worth the time if this is your use case.

Solid for our team

We rolled this out across the team last quarter and it saves real time. The API fits neatly into how we already work, and the automation removed a step we used to do by hand. Pricing gets steep at scale, which is the main caveat, but it has held up under daily use.
