Security and privacy decision
Blurweb.app
A single competent developer can build and maintain a local-only browser extension that matches the core BlurWeb functionality in about a week; the vendor's cloud sync and license infrastructure are the main things you would not replicate.

Not priced
No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.
$100one-off32 h to build

No published price to break even against.
No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- User installs a browser extension, hovers or draws a rectangle to select page elements, the extension overlays a blur on those elements and optionally saves the rule locally so the blur persists on page reload.
What it still won’t have
- Cross-device sync and centralized license management (the product advertises sync across devices and license activation)
- Official paid support, updates and license recovery workflows
- Any server-side features the vendor may add later (analytics, remote revocation of licenses)
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Blurweb.app does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a cross-browser extension (TypeScript, Webpack/Rollup, Manifest V3) with a React/Preact popup and a content script that: 1) adds an in-page hover selector and allows drawing a rectangle to choose an area; 2) applies a CSS blur overlay to the selected DOM node(s) and supports an adjustable blur intensity; 3) persists per-domain blur rules in chrome.storage.local (or browser.storage.local) and re-applies them on page load using selectors and element position heuristics; 4) uses MutationObserver to reapply blurs on dynamic pages; 5) provides UI to keep/clear blurs and keyboard shortcuts; 6) includes build scripts for Chrome/Firefox/Edge, extension manifest, CI tests (unit for core utilities and integration tests with puppeteer/playwright), error handling and telemetry-free privacy-safe logging. Out of scope: server-side sync, license verification, and paid account management.
How we checked
How the score was reached
- Build verdict base78
- 3 cited sources+3
- Evidence score81
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
