Blackfire: sovereignty score and 8 European alternatives

Blackfire is a profiling and performance monitoring service for PHP and Python applications. Developers measure at function or line level where a web application spends time and memory, monitor performance continuously in production and include performance tests in CI/CD. Frameworks such as Symfony, Laravel and Django are supported. A probe on the customer's own servers sends profiles to the Blackfire service, which shows them in a web interface. It is an alternative to APM services such as New Relic or Tideways.

Blackfire is a trademark of Platform.sh SAS, trading as Upsun, a French company headquartered in Paris; Blackfire joined forces with Platform.sh in 2021. The privacy notice also names a US affiliate, Platform.sh Inc., which participates in the EU-US Data Privacy Framework. The legal notice states that the website is hosted by Amazon Web Services in Ireland; Amazon is a US company. The company says the service has been audited by an external expert for GDPR compliance. A European organisation should check where profile data is stored and which processing terms apply.

Why digital sovereignty matters with Blackfire

Blackfire is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Blackfire scores best on data residency.

Blackfire is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Blackfire together with your other vendors and gives a total score, a heatmap and the main risk drivers.
