Blur It Alternative: Which Screen Blur Extension Should You Use?

Looking for a Blur It alternative - or deciding whether to buy it at all? The short version: DataBlur solves the same problem with a free unlimited tier, a 3-day trial and a redact mode that hides content completely, while Blur It is a $49.99 purchase you can't try first, with blur as its only hiding mode. Here's the full comparison, with every claim checkable against the public Chrome Web Store listings.
You're probably here because you're about to spend money on one of these tools, or already did and have doubts. Fair. Both promise the same outcome, both cost about $49 for lifetime access, and both look similar in screenshots. The differences only show up when you look at how each one actually blurs, what happens when a page reloads mid-call and what you can verify before paying.
We build DataBlur, so read this with that in mind. But every technical claim below comes from public sources - the extensions' own store listings, their published code bundles and their websites. You can check all of it yourself.
Key takeaways
- Both extensions use adjustable CSS blur, but only DataBlur adds a redact mode that removes content from the rendered page instead of smearing it
- Blurred text can often be recovered - our 480-case study showed it. Redaction can't, and only DataBlur has it
- Blur It applies blurs after the page paints, so viewers see your data unblurred for a moment on every reload. DataBlur restores blurs before first paint
- Blur It's manifest requests access to analytics and backend servers (PostHog, Supabase). DataBlur's manifest requests no external hosts, and its optional anonymous analytics has an off switch
- DataBlur has a free unlimited tier and a 3-day trial. Blur It is a $49.99 purchase with no free plan and no trial - though it does offer a 30-day money-back guarantee
What both tools get right
Credit where it's due. Blur It covers the fundamentals: click an element to blur it, drag a box over a larger area, auto-detect emails and numbers, adjust blur strength with a slider, keep blurs in place through page refreshes. Its blurs show up in Zoom, Meet, Loom and OBS because they're applied at the browser level. That's the correct architecture for this problem - the same one DataBlur uses.
Blur It also holds a 4.1-star rating on its Chrome Web Store listing at the time of writing, and backs purchases with a 30-day money-back guarantee through Polar, its payment provider. If you buy it and it doesn't work for you, you can get your money back within 30 days.
So the question isn't whether Blur It works at all. It's whether the details hold up when your real client data is on screen.
The blur method: blur-only vs blur plus redact

Something most comparison pages skip: CSS blur, the standard way browser extensions obscure content, is not a vault. It's a visual filter drawn over live page content. The text is still in the page underneath.
Both DataBlur and Blur It use adjustable CSS blur as their base mode - Blur It defaults to 5px with a strength slider, DataBlur defaults to 10px with a 0-25px range. On that axis they're close, and we won't pretend otherwise.
The real difference is what happens when blur isn't enough. Blur It stops at blur. DataBlur has two more modes:
- Redact: text is rendered with a censor-bar font and everything else gets an opaque black box. The content isn't obscured - it's gone from the rendered output. There's nothing to recover
- Transparent: the element is hidden entirely, with a built-in safeguard that falls back to redaction on area overlays so hiding the overlay can't reveal what's underneath
Why recoverability matters
We ran the test ourselves. In our blur recovery study, we attempted to recover blurred, pixelated and redacted text across 480 cases. The uncomfortable finding: light Gaussian blur on text is frequently recoverable with modern tools. Blur It's 5px default sits inside that risky range, and even a stronger blur is still pixels derived from your data.
That study is exactly why DataBlur has a redact mode. We proved to ourselves that blur alone isn't always enough, then built the mode that fixes it. If you're hiding an account number for a moment of visual tidiness, blur is fine. If you're hiding an API key from a recording that will live on YouTube forever, use redact - the pixels of your key are never drawn at all.
With Blur It, blur is the only mode there is.

The reload problem: what viewers see for a split second

Picture a live demo. You've blurred your customer table, you're mid-pitch, and you click a link or hit refresh. What do viewers see while the page loads?
This comes down to one line in each extension's manifest - when the content script runs.
Blur It runs its script at document_end. The page paints first, then the script wakes up and re-applies your blurs. On every navigation and every reload, there's a moment where your sensitive data is on screen, unblurred, in front of everyone. You can verify this in the extension's own manifest file, which is public in its Chrome Web Store bundle.
DataBlur takes the opposite approach. It runs at document_start, holds the page hidden and stamps cached blurs into place before the first paint. The page appears already blurred. There is no flash, because the unblurred state is never rendered.
For a tool whose entire job is protecting you during live screen sharing, this is the difference that matters most. A blur that takes a coffee break on every reload isn't protection - it's decoration.
Privacy: check the manifest, not the marketing

Blur It's website says: "No data (emails, credit cards, or text) is ever sent to our servers." For page content, that appears to be true - and the same is true of DataBlur. Both tools blur locally. Neither sends what you blur anywhere.
The difference is everything else that travels. Blur It's manifest - public in the store bundle - requests host permissions for two external services: us.i.posthog.com (analytics) and *.supabase.co (its backend). It sends usage events and license checks tied to an anonymous ID, and the comments in its own published code describe that ID as designed to be cross-referenced between its analytics, its backend and its Polar checkout data.
To be clear: that's telemetry, not content exfiltration. Plenty of software does it. But "nothing is sent to our servers" and "we run analytics and license checks against two external services" are different promises, and you deserve to know which one you're getting.
DataBlur has usage analytics too - we won't pretend otherwise. Ours is anonymous, collects no IP address, no user agent and no hostnames, and has an off switch: turn off analytics consent and nothing is sent, ever. The only other network call is a license check when you activate a DataBlur Pro purchase. And DataBlur's manifest requests no external host permissions at all - open both manifests side by side and the difference takes two minutes to see.
If your work is covered by client confidentiality agreements or compliance rules, those two minutes are worth spending.
Pricing: try before you buy vs buy before you try

The lifetime prices are nearly identical. The path to them isn't.
With Blur It, the first time you can touch the product is after paying $49.99. There's no free version and no trial. The 30-day money-back guarantee is a real safety net - but it means the refund process is the trial.
With DataBlur, you evaluate in stages. The free tier is genuinely unlimited - every blur mode, auto-detection, keyboard shortcuts - with a small "Blurred with DataBlur" badge as the only limitation. When you want the badge gone plus saved blur profiles, DataBlur Pro starts a 3-day trial from inside the extension, no card required. Then you choose: $4.99 a month or $49 once.
You find out whether the tool fits your workflow before money moves. That's how buying software should work.
Engineering signals: 95 MB vs under half a megabyte

One more thing you can verify on the store listings: download size.
Blur It's package is roughly 95 MB. For context, a typical blur extension is under 5 MB. The reason, visible in the public bundle, is that Blur It ships its marketing videos inside the extension - over 90 MB of demo MP4s that every user downloads and stores, on every machine, on every update.
DataBlur's bundle is under half a megabyte. Demo videos live on the website, where they belong.
Does bundle size affect blur quality? Not directly. But you're trusting this tool to behave correctly during the highest-stakes moments of your work week. How a team handles the basics - what ships in the package, when scripts run, what the manifest requests - tells you how they'll handle the parts you can't see.
Who Blur It is for
An honest recommendation cuts both ways. Blur It is a reasonable pick if:
- You want the simplest possible tool with blur as the only mode and little to configure
- Blur alone genuinely covers your risk level - casual streaming, low-stakes screenshots
- You're comfortable buying first and using the 30-day guarantee as your evaluation window
- Its telemetry doesn't conflict with your confidentiality obligations
Who DataBlur is for
DataBlur is the better fit if:
- You show real client or customer data on live calls, where a reload flash or a recoverable blur is an actual incident
- You record content that lives forever - tutorials, demos, YouTube videos - and want redaction, not just blur
- Your confidentiality or compliance obligations require that page content verifiably never leaves the browser, and that analytics can be switched off entirely
- You want to try the full tool before paying anything
The deeper difference is philosophy. Blur It treats blurring as a visual effect. DataBlur treats it as a safety system, built on the assumption that one careless moment shouldn't be able to hurt you.
FAQ
Is Blur It's blur recoverable?
Sometimes, yes. Blur It applies CSS blur (5px by default) over live page text, and our 480-case recovery study found that light Gaussian blur on text can often be recovered. For anything high-stakes, use a redaction mode that removes content entirely - which Blur It doesn't offer.
Does DataBlur have a free version?
Yes. The free tier is unlimited - all blur modes, auto-detection, keyboard shortcuts and persistence - with a small watermark badge on blurred areas. Pro removes the badge and adds saved profiles for $4.99/month or $49 lifetime.
Can I try DataBlur before paying?
Yes. Beyond the free tier, a one-time 3-day Pro trial starts from any upgrade prompt in the extension. No card, nothing to cancel - it reverts to free automatically.
How do I get a refund from Blur It?
Blur It sales are processed by Polar, its merchant of record, and come with a 30-day money-back guarantee. Use the customer portal link in your order confirmation email or contact the developer through blur-it.app. DataBlur can't process Blur It refunds - we're a different company, despite what the similar names suggest.
The bottom line
Both tools blur your screen. Only one lets you verify everything before spending a cent. And if you're still mapping the wider space, our guide to screen blur tools compares six options beyond these two.
If you compare them yourself - and you should - check three things on the public listings: what modes exist beyond blur, when the content script runs and what external hosts the manifest requests. Those three details are the whole story of this comparison.
Or skip ahead: install DataBlur free, blur something sensitive, hit reload and watch what happens. Then try the same test with anything else. Your screen data deserves the tool that passes.
