Flare is the only error tracker for Laravel applications that suggests a fix. It's a Software-as-a-Service application that tracks errors in production applications and notifies your team if something goes wrong.

Flare is built and run by Facade, a joint venture between Beyond Code and Spatie. You can get more information about Flare here.
