The OneTab alternative that restores your tab groups
OneTab has 2M users and a 4.5-star rating because it does one thing fast: collapse a full window into a single list of URLs and reclaim the memory. The reason power users start hunting for an OneTab alternative is what that list leaves out — when OneTab saves your tabs it discards group membership, so the Chrome tab-group titles, the nine colors, and the collapsed state you set up are gone the moment you restore. Add the long-running reports of data loss after some Chrome updates, plus the slowdown once a list passes 1,000 tabs, and the flat-list model starts to cost more than it saves. Tabwell is the OneTab alternative built for the part OneTab drops: a snapshot records each tab's group assignment through the chrome.tabGroups MV3 API, restore rebuilds every group with its original title, color, and collapsed state, and every snapshot stays local in IndexedDB on your device — no account, no server, no telemetry by default. If you already live in OneTab, the built-in importer pulls your existing OneTab export across in two clicks, so moving over costs you nothing.
Why OneTab users start looking for an alternative
OneTab stores your tabs as a flat list of URLs. That is enough to free memory, but a Chrome tab group is structural — it has a title, one of nine colors, and a collapsed or expanded state. OneTab records none of it, so restoring an OneTab list hands you back a wall of tabs you must re-group by hand. Two more limits push people to switch: the long-running reports of data loss after some Chrome updates, and the slowdown once a saved list passes 1,000 tabs.
What the best OneTab alternative 2026 needs to do
If you are replacing OneTab rather than dumping it, the replacement has to keep what OneTab discards. The short list:
- Restore Chrome tab groups with their title, color, and collapsed state — not a flat URL list.
- Store snapshots locally so tab URLs and titles never leave the device.
- Stay usable on large sessions instead of degrading past 1,000 tabs.
- Import an existing OneTab export so the switch is not a manual copy-paste job.
How Tabwell fills the gap
Tabwell snapshots the group structure alongside the tabs and rebuilds each one through chrome.tabGroups, so three collapsed colored groups come back as three collapsed colored groups. Every snapshot is written to IndexedDB on the device via dexie — there is no account and no cloud by default, and the only network request is a license check to Polar that carries no tab data. Tabwell also takes an auto-snapshot when the browser exits and offers to restore it on the next launch, and on Pro it indexes the title and URL of every saved tab for full-text search.
Migrating from OneTab in two clicks
- In OneTab, use its export to copy out your saved tabs.
- Open Tabwell and choose the built-in OneTab importer.
- Paste or load the export — your tabs come across in two clicks, no manual re-entry.
When to choose OneTab instead
OneTab is still the right pick for one job: a dead-simple, one-click memory dump when you do not care about structure. With 2M users and a 4.5-star rating it is mature and familiar, and if you never use Chrome tab groups — you just want loose tabs out of the way to reclaim RAM — the round-trip gap Tabwell closes will not matter to you, and there is no reason to switch.
FAQ
Is Tabwell a free OneTab alternative?
Every install includes a 14-day Pro trial, no credit card required. After it ends, Free keeps your latest 5 snapshots with manual save and restore, JSON export, and 60-minute auto-snapshots. Pro adds unlimited snapshots, full-text search, and importers from $3.99/month, $29/year, or a one-time $19 Founders license for the first 1000 buyers ($59 after). Refunds are 30-day, no questions asked.
Can I import my existing OneTab tabs into Tabwell?
Yes. Tabwell ships a built-in OneTab importer. Export your tabs from OneTab, then load that export in Tabwell in two clicks. Your tabs come across without manual copy-paste, so switching from OneTab costs you nothing.
Does OneTab really discard my tab groups?
OneTab saves tabs as a flat list of URLs and does not record group membership, so the group titles, the nine Chrome colors, and the collapsed state are gone on restore. Tabwell records each tab's group assignment and rebuilds all three through the chrome.tabGroups API.
Is Tabwell local-first like OneTab?
Yes. Tabwell stores every snapshot locally in IndexedDB on your device via dexie, with no account and no cloud by default. Tab URLs and titles never leave the machine; the only network call is a license check to Polar that carries no tab data. Optional cross-device sync is opt-in.
Which Chrome version does Tabwell need?
Chrome 114 or newer, because Tabwell uses the chrome.sidePanel API introduced in that release. It is built for Chrome on Manifest V3 with an MV3 service worker. Edge and other Chromium browsers may work but are not the supported target, and Firefox and Safari are not supported.
