Does the job

Pretty happy overall. The core workflow just works and it saves real time. but no dealbreakers — I'd recommend it to a friend without hesitating.

Years in this space

I've evaluated a lot of these over the years. What stands out here is the integrations — handled better than most — and it saves real time. Worth the time if this is your use case.

Compared a few options

Evaluated this against two competitors. Where it wins: the automation and it saves real time. On balance the feature set — especially the API — justifies the 5 stars for our use case.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on the integrations, and support is responsive caught me off guard. still, I'd recommend giving it a real trial.
