Source: https://symfony.com/
Can Symfony be self-hosted?
We have only confirmed a cloud / SaaS deployment for Symfony, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.
Source: https://symfony.com/
What does Symfony integrate with?
We have confirmed 4 integrations for Symfony, including Drupal, Laravel, API Platform and Composer. This is what we could verify from public sources, so the vendor may support others we have not indexed.

What security certifications does Symfony have?
We have independently confirmed GDPR for Symfony. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Symfony not holding them. Always confirm compliance directly before you rely on it.
Is Symfony open source?
Yes. Symfony is published under the MIT licence, a permissive licence that generally allows commercial use and modification. Licence terms can change between releases, so verify against the repository for the version you intend to use.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Symfony, not the verdict.
