Is your stack still supported?
Paste a composer.json, package.json, pyproject.toml, Dockerfile, compose file or .nvmrc. It finds the versions it pins — PHP, Laravel, Node.js, Python, PostgreSQL, MySQL, Redis, nginx, Ubuntu, Django, Next.js and 59 components in all — and whether each still gets security fixes. Paste a composer.lock or package-lock.json to also check every exact package version for known vulnerabilities.
The file never leaves this page. The optional vulnerability check sends only package names and versions.
Results appear here as you paste.
Dates come from the official schedules, listed with sources on the end-of-life dates page and refreshed monthly from endoflife.date. On Laravel? The upgrade planner shows every step to Laravel 13. The check reads the lowest version a constraint allows, so ^8.1 counts as PHP 8.1 — the version your code still promises to run on.
