Fifty sites, and the seven you will actually use
A bookmark list worth keeping — every domain checked, two had quietly moved
Fifty free web tools grouped by the job they do, rather than listed flat. All fifty were checked and every one is still up — but two have changed address since the list was written. The advice that makes it usable is in the list itself: do not try all fifty, pick the seven that match your week.
A list of fifty is a list of none — you bookmark the lot, use nothing, and forget the folder exists. The instruction that makes it work: pick seven that match the work you are actually doing this week, put them in one folder called Tools, and ignore the other forty-three until a job asks for them. The groupings below exist so you can find your seven fast.
Rescue, reference and learning
Images and design
Words, files and research
Developer
Safety, network and everyday
Checked live: notion.so now 301-redirects to notion.com, and notebooklm.google.com 301-redirects to notebook.google.com. Both old addresses still work, so nothing is broken, but the canonical names have changed and the tables above use the current ones. Every other domain on the list resolves — the handful that refuse an automated request are bot protection, not dead sites.
Stack them by task, not by bookmark
The point of a list this size is not the individual sites, it is that a few of them chain into a job you do repeatedly.
