Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on the core workflow, and support is responsive caught me off guard. The docs could be deeper is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Does the job

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

Use it every day

Honestly didn't expect to like it this much. The API is exactly what I needed, and it saves real time. I do wish pricing gets steep at scale, but I reach for it almost every day now and it just clicks.

Compared a few options

Evaluated this against two competitors. Where it wins: the dashboard and support is responsive. Where it lags: pricing gets steep at scale. On balance the feature set — especially the onboarding — justifies the 5 stars for our use case.

Honestly didn't expect to like it this much. The integrations is exactly what I needed, and the value for money is strong. I do wish the docs could be deeper, but I reach for it almost every day now and it just clicks.
