Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on the core workflow, and it saves real time caught me off guard. A few rough edges remain is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Solid for our team

We rolled this out across the team last quarter and it saves real time. The core workflow fits neatly into how we already work, and the API removed a step we used to do by hand. but it has held up under daily use.

Solid for our team

We rolled this out across the team last quarter and support is responsive. The onboarding fits neatly into how we already work, and the automation removed a step we used to do by hand. The mobile experience lags, which is the main caveat, but it has held up under daily use.

Years in this space

I've evaluated a lot of these over the years. What stands out here is the dashboard — handled better than most — and it is genuinely easy to set up. Worth the time if this is your use case.
