Karakeep vs OneTab: Which is better? (2026)
The short answer
These two solve different problems. OneTab is a free pressure valve for an overloaded browser; Karakeep is a permanent, AI-organized library for things worth keeping. If tabs are the pain, take OneTab; if finding saved content later is the pain, take Karakeep.

About Karakeep
Karakeep is an open-source "bookmark everything" app, launched as Hoarder and renamed in early 2025. It is built for self-hosting: a Docker install stores links, notes, images, videos, and PDFs on your own server, with full-page archiving to guard against link rot. AI does the filing — automatic tagging and summaries run through any OpenAI-compatible API or a local Ollama model, so nothing has to leave your machine. Search is Meilisearch-backed full text, with semantic and hybrid modes added in 2026. Around the core are browser extensions for Chrome, Firefox, and Safari, iOS and Android apps with offline reading, highlights, shareable public lists with RSS feeds, a REST API, and an MCP server for AI agents. Imports cover Pocket, browser bookmark HTML, Omnivore, Instapaper, Linkwarden, and mymind exports. A hosted Karakeep Cloud is in public beta, with a Pro tier at $4 per month.
About OneTab
OneTab is a free browser extension from UK-based OneTab Ltd that collapses every open tab into a single list with one click, cutting browser memory use by up to 95% by the developer's estimate. Tabs restore individually or all at once, and any list can be shared as a hosted web page. First released in 2013, it spent years nearly unchanged before a full v2 rewrite in 2026 added folders, in-list search, stars and tasks, and dark mode, with end-to-end-encrypted sync announced as coming soon. It stores only URLs and titles, locally in the browser profile — nothing is transmitted to the developers — and there is no account to create. Extensions exist for Chrome, Edge, and Firefox, plus a Mac-only Safari app that lags well behind. Export is a plain-text URL list. The whole product is free, with more than two million Chrome users, no limits, and no paid tier.
Which should you choose?
Comparing Karakeep to OneTab is really comparing two different problems. OneTab answers browser overload: one click sweeps every open tab into a list, reclaiming memory and visual sanity, with nothing stored but URLs and titles in your local browser profile. Karakeep answers knowledge loss: content you save is archived in full on your own server, tagged by AI, and retrievable through full-text and semantic search years later. Triage versus preservation — many people genuinely need both.
Choose OneTab if:
- Your actual problem is 80 open tabs and a wheezing laptop, not a research archive — parking tabs is the whole job.
- You want zero commitment: no account, no server, no configuration, and completely free with no limits.
- Privacy through absence appeals — your tab URLs never leave the browser unless you deliberately share a list as a web page.
Choose Karakeep if:
- What you save needs to survive: OneTab keeps a bare link, so a dead page means the content is gone, while Karakeep keeps page copies, screenshots, and PDFs.
- You need your library everywhere — Karakeep pairs its server with iOS and Android apps and offline reading, whereas OneTab has no mobile story at all.
- Search is non-negotiable: AI tagging plus Meilisearch full-text and semantic modes, against OneTab’s simple in-list search.
The honest verdict: this is an odd-couple matchup, and pretending otherwise helps nobody. OneTab is arguably the best free tab parker ever shipped — and a risky place to keep anything precious, since clearing browser data can wipe the list. Karakeep is a serious self-hosted archive that demands Docker and setup effort. Park your tab chaos in OneTab today; move anything you would mind losing into something like Karakeep.
The option both sides overlook
If the real problem is finding things again, neither Karakeep nor OneTab fully solves it. Marqly auto-tags and summarizes every save with AI and lets you retrieve any of them by describing what you remember — plus a highlighter, YouTube summaries with transcripts, and save-as-PDF. There's a free tier with no card required.
Karakeep vs OneTab FAQ
Can OneTab replace a bookmark manager like Karakeep?
Not safely. OneTab stores only URLs and page titles, locally in one browser profile — there is no page content, no full-text search, and uninstalling the extension deletes your stored tabs. Karakeep archives a copy, screenshot, and PDF of each page on your own server, auto-tags it with AI, and makes it searchable by text and meaning.
Does Karakeep have a save-all-tabs feature like OneTab?
No. Karakeep's extensions for Chrome, Firefox, and Safari save pages one at a time, and one-click save-all-tabs is a noted gap. OneTab's entire purpose is that single click: collapse every open tab into a list, cutting browser memory use by up to 95% by the developer's estimate, then restore tabs individually or all at once.
Are Karakeep and OneTab both free?
Yes, in different senses. OneTab is entirely free — no account, no limits, no paid tier — though its promised encrypted sync is still unpriced and unreleased. Karakeep is free when self-hosted, but you provide a Docker server and your own AI key or Ollama model; the hosted Cloud option offers a 10-bookmark free tier and a $4/month Pro plan.
