Great for the price, super useful for a wide variety of teams

SolarWinds Papertrail is a great logging platform, especially for Heroku or other PAAS. The UI is extremely simple - it shows logs like tail -f might - but you can get a lot out of it without a ton of setup. The search is very fast, and you can configure log alerts. This allows you to a) be alerted if something happens you aren't expecting, but more importantly, b) add logging to your app and have SolarWinds Papertrail alert you as a way to get basic observability. SolarWinds Papertrail is not a competitor to Datadog or Honeycomb, but is the perfect logging system for a small team, though it certainly scales up quite well. At a previous company, we were using SolarWinds Papertrail almost until we went public at a 1B valuation.
