# Manage continous observability with Blackfire

> Set up a continuous observability strategy for your Symfony app with Blackfire.

[Blackfire.io](/docs/observability/application-metrics/blackfire) is the recommended solution
for monitoring and profiling web sites and apps.
Blackfire works seamlessly with any app built with Symfony.

Blackfire PHP SDK provides the following [integrations with
Symfony](https://blackfire.io/docs/php/integrations/symfony/index):

* [Symfony HTTPClient](https://blackfire.io/docs/php/integrations/symfony/http-client)
* [Symfony Messenger](https://blackfire.io/docs/php/integrations/symfony/messenger)
* [Symfony CLI Commands Monitoring](https://blackfire.io/docs/php/integrations/symfony/cli-commands-monitoring)
* [Symfony Functional Tests Production](https://blackfire.io/docs/php/integrations/symfony/functional-tests)

A `.blackfire.yaml` file is provided within the [Symfony Templates](https://github.com/symfonycorp/platformsh-symfony-template/blob/7.2/.blackfire.yaml)
to help you bootstrap the writing of custom [performance tests](https://blackfire.io/docs/testing-cookbooks/index)
and automated [builds](https://blackfire.io/docs/builds-cookbooks/index).
