The short version: Every Time Zone is a free, web-only horizontal timeline for comparing cities. World Time Buddy is the closest direct alternative, also free and web-based with a drag-to-compare slider. timeanddate.com is the deeper reference tool if you need exact conversion detail. Doodle solves a different, adjacent problem: polling a group for availability rather than just showing the overlap. All four leave the actual scheduling to you; Atlas is the native Mac app that also recommends the best time and books it.
Every Time Zone earns its popularity honestly: a clean, colour-coded timeline that's pleasant to glance at and free to use. If you're comparing alternatives, here's how the other well-known web tools stack up, and what changes once you want the app to do more than just show you the picture.
World Time Buddy: the fast overlap reader
World Time Buddy is the most direct alternative: also free, also a browser tab, with a horizontal hour grid you drag across the day. The main difference from Every Time Zone is presentation rather than capability, both show the same kind of overlap, just with different visual styling, so picking between them is mostly a matter of taste.
timeanddate.com: the deep reference
timeanddate.com is the tool to reach for when you need exact detail: historical daylight-saving dates, precise UTC offsets, sunrise and sunset times, rather than a quick visual read. It's free, it's been a reference standard for decades, and it's the most exhaustive of the group, at the cost of being less pleasant for a quick glance than a timeline-style tool.
Doodle: a different job entirely
Doodle doesn't show an overlap at all, it polls a group and lets each person vote on which proposed times actually work for them. That's the right tool when you don't already know everyone's working hours and need to ask, a genuinely different problem to the one Every Time Zone is built to solve.
What none of these do
All four are free, all four are web-based, and all four stop at showing you the picture: you still have to read the overlap yourself, judge which slot is fairest, and create the calendar event by hand. None of them remembers your team from one session to the next either, you re-enter the same cities every time you reopen the tab.
Where a native app finishes the job
Atlas starts from the same idea, seeing where people's hours overlap, but it's a native Mac menu-bar app rather than a browser tab. It remembers your team so you don't re-enter it each time, and it goes one step further: it auto-suggests the best overlapping meeting time and adds it to your calendar in one tap, in everyone's correct local time, for a one-time $4.99.
Plenty of people start on a free web timeline and only move to a native app once cross-zone scheduling becomes a weekly habit rather than an occasional one-off. There's no wrong choice for a rare check, keep using what's free until the friction actually costs you time.

So which should you choose?
If you want the same quick visual read as Every Time Zone, World Time Buddy is the closest like-for-like swap. If you need exact reference detail rather than a glance, timeanddate.com goes deeper. If you don't already know everyone's hours and need to ask, Doodle is built for exactly that. If you're on a Mac and check overlap often enough that re-entering cities and creating events by hand has become real friction, Atlas does the whole job for a one-time $4.99.
