Which has better long term support, Laravel or Symfony?

Both have mature LTS discipline. Laravel ships LTS releases with bug fixes for two years and security fixes for three (Laravel 11 LTS receives security fixes into 2027). Symfony has a long established LTS cadence with a new LTS roughly every two years and extended support windows. For enterprises that need predictable, long supported versions, both frameworks provide that assurance. The LTS question is rarely the deciding factor between them because both are well supported; the decision usually comes down to productivity versus control and team skill.
