Our choice for remote logging. Their slick interface helps us monitor logs. They've got excellent integration with Slack, pings us when something needs attention and extremely good customer support.
Support is responsive, the tool does what it's supposed to do, the interface is sleek, even though a few creature comforts are missing.
However, they keep iterating all the time and it keeps getting better.
The prices are a bit higher for the paid plans, but the free tier is generous.
