Zovo Lean

Save bandwidth and speed up pages with content blocking, per-site page weight, Lite Mode, Startup Boost, and monthly reports.

Browse lighter. Start faster. Zovo Lean is a bandwidth and speed saver built on the proven GPL-licensed uBlock MV3 filtering engine. It blocks unwanted network requests and turns the result into a simple answer: how much data did this page use, and how much did the extension likely save? What you get: • A per-site meter for estimated data saved, page weight, and skipped requests • Lite Mode to block images, fonts, and heavy media on the current site • Startup Boost to pause third-party scripts when your connection is slow or data-saving mode is active • A monthly bandwidth report with per-domain totals and CSV export • Three upstream filtering strengths, custom filters, and established compiled filter lists Measurements stay local. Zovo Lean observes response Content-Length headers; it does not read response bodies. Because a blocked response has no body to measure, saved-byte figures are transparent estimates based on observed response-size averages. Lite Mode is site-specific and reversible in one tap. Startup Boost uses a session-only rule, so it is automatically removed when it is not applicable. The blocker and current-month bandwidth report are free. Optional supporter features use keys purchased at https://zovo.one/pricing. A key grants access only after the verifier returns valid: true. Zovo Lean contains no telemetry and no remote executable code. Complete modified GPL-3.0 source, upstream attribution, and the statement of changes: https://github.com/theluckystrike/zovo-lean
