Bugfender is an error tracking service from Germany built around log storage. Because it keeps the full log stream, you can read the sequence of events leading up to a crash rather than the crash alone, and logs written while a device is offline are stored locally and synchronised later. It is built for mobile and web applications.
The service is hosted in the Netherlands, so crash and log data stays in the EU, which makes it a European alternative to American crash reporting tools. It suits mobile teams that need to reproduce bugs which only show up on real devices.

The free plan covers up to 100,000 log lines with 24 hours of retention. Paid plans start at 49 euro per month for one million log lines and seven days of retention.
