- OneTab: OneTab has a free tier. Entirely free: no paid tier, no limits, no account required. The announced end-to-end-encrypted cross-device sync is 'coming soon' with no pricing stated, so whether sync stays free is unknown.

About Obsidian Web Clipper
Obsidian Web Clipper is the official, open-source browser extension for Obsidian, the local-first Markdown note app. It runs on Chrome, Firefox, Edge, and Safari — including Safari on iOS and iPadOS — and saves pages, selections, or highlights as clean Markdown files in your vault, where they stay on your own disk with zero lock-in. Per-site templates decide how each clip is titled, tagged, and filed, pulling metadata through selector and Schema.org variables. An optional Interpreter feature runs natural-language prompts at clip time — summarize, extract, translate — using your own API key from Anthropic, OpenAI, Gemini, and others, or a local Ollama model at no cost. Everything is free, including commercial use of Obsidian since early 2025. The trade-off is that cloud conveniences are add-ons: cross-device sync via Obsidian Sync starts at $4 per month, and public sharing via Obsidian Publish costs $8 per site 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?
Rare in a comparison: these two share values and split cleanly on function. Both cost nothing, keep data local, and treat privacy as non-negotiable — OneTab never phones home; Obsidian writes files to your own disk. The split is what happens to a page you act on. OneTab remembers that a tab existed, storing its URL and title in a list. Obsidian Web Clipper keeps what the page said, converting it — or just the passages you highlighted — into Markdown inside your vault.
Choose OneTab if:
- Volume is the enemy: dozens of tabs need parking now, and clipping each one into a note system would be absurd overhead.
- You want a tool with no dependencies — no companion app required, whereas Obsidian’s clipper is only useful if you run Obsidian itself.
- Restoration is the use case: parked sessions reopen individually or wholesale, a workflow a notes vault cannot replicate.
Choose Obsidian Web Clipper if:
- Content deserves to outlive its tab — articles, documentation, and reference pages saved as durable, searchable Markdown.
- You annotate as you read: highlighter mode captures exactly the passages you marked, with per-site templates handling titles and tags.
- Your phone is part of the pipeline — the Safari extension on iOS clips to your vault, while OneTab has no mobile presence at all.
Bottom line: this odd couple is best resolved with “and,” not “or.” Let OneTab absorb the daily tab flood, accepting that its list is disposable by design. Route the few pages carrying real information through Obsidian’s clipper into files you own permanently. Since both are free, the only cost of running both is learning which click each moment deserves.
The option both sides overlook
If the real problem is finding things again, neither Obsidian Web Clipper 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.
Obsidian Web Clipper vs OneTab FAQ
Do Obsidian Web Clipper and OneTab compete at all?
Not really — they are neighbors, not rivals. OneTab is browser triage: one click collapses every open tab into a local list of URLs, cutting memory use by up to 95% per the developer. Obsidian's clipper is knowledge capture: a page, selection, or set of highlights becomes a Markdown file in your vault. Many people sensibly run both extensions side by side.
Which is safer for long-term data?
Obsidian, structurally. Clips are plain Markdown files on your disk — full page content included — readable by any text editor for decades. OneTab keeps only URLs and titles inside one browser profile: uninstalling the extension deletes the list, clearing browser data can wipe it, and if a linked page dies, its content was never saved anywhere. Treat OneTab as scratch space.
Are both really private?
Yes, both to an unusual degree. OneTab never transmits your tab URLs to anyone — everything stays in the browser unless you deliberately share a list as a web page. Obsidian's clips live entirely on your own machine, with even AI features (the Interpreter) able to run against a free local Ollama model, so page content need never leave your computer.
