OneTab, in a line: Turns every open tab into one list with a click, to restore later one at a time or all at once. If it is not quite right, these are the extensions that cover the most of what it does, ranked by which of its features each one shares - with what they cost and where they run.
Facts read from each product’s own store listing and website on 13 October 2026. We make Latr, so it is listed first and marked as ours; the rest are ranked by the numbers.
What OneTab does
OneTab offers 5 of the 15 things we compare. An alternative is only an alternative if it keeps the ones you use.
The alternatives
Tab snoozer
OneTab is a place to put tabs; Latr is a time to get them back. OneTab’s whole gesture is "clear this window now", and the list waits, unsorted by urgency, until you open it. Latr asks one question OneTab does not - when do you need this again? - and then the page reopens itself at that moment, at the paragraph you were on. If you never need a tab at a particular time, OneTab’s single click is hard to beat. If the reason a tab is open is that something happens on Friday, a list does not remind you on Friday.
Covers 5 of OneTab’s 5 features. Adds: brings a tab back at a time you choose, repeating reminders, reopens at the line you stopped reading, saves sessions automatically, keeps tab groups, manages every open tab, across windows, finds duplicate tabs, puts idle tabs away automatically, focus timer with site blocking.
Unlike OneTab, it also runs on Brave, Vivaldi, Opera, Arc, and, like OneTab, it is free to start (Free; Pro is $19 once, for themes, sounds and extras).
Choose Latr over OneTab if the tabs you are hoarding are waiting for a moment - a sale, a deadline, a reply - and you want each one back at that moment rather than in a list you have to remember to open.

Switching
Use OneTab’s export to copy your list as text, and paste it into Latr’s import (Settings, Your data, Bring in what you already have): every blank line in OneTab’s export is a group, and each group arrives in Latr as its own folder, with the page titles OneTab wrote. Nothing is scheduled - imported pages land in the library with no time until you give them one.

Questions
OneTab does a lot well. One click turns a whole window into a list - the simplest gesture in the category. People look elsewhere for what it does not offer, going by its own listing. Nothing in its listing or site schedules a tab to come back - the list waits until you go back to it. Sharing uploads your list to a web page; it is the one feature that sends your tabs anywhere. The installed extension asks for tab access up front.
Of the alternatives on this page, Latr, Toby, Tab Stash, Tab Session Manager, Workona and PingLater are free to start.
