endoflife.date is an informational website that tracks support cycles and release schedules of over 60 products.

The complete website is open-source, and we are always working to make it better.
We are more than 4 years old, and have 100+ contributors.
The site doesn't cost us much to maintain, so your money goes towards funding developers and our dependencies.
