Spot new Chrome extensions before everyone else

A listing with a confirmed publication date inside your chosen window — 24 hours, 7 days, or 30 days. Entries whose release date is unknown move to a separate “recently discovered” list, so the chart of new Chrome extensions stays honest about what it actually measures rather than blending guesses into the ranking.

Store shelves mostly sort by lifetime popularity, which favors giants that launched a decade ago. ExtensionRadar highlights new Chrome extensions and early movers instead, ranking them by verified short-window growth with published observation dates and confidence scores — so a two-week-old tool with real traction can outrank a famous name.

Weekly public datasets published by Extension Tracker (used under CC BY 4.0), combined with our own daily sitemap sweep and targeted store-page sampling. Every row names its source, and the methodology page explains in detail how the three supply lines are reconciled into one auditable dataset. Each supply line has different strengths — bulk history, earliest discovery, freshest counts — and the pipeline records which one produced every number you see — the fastest way to trust new Chrome extensions as a market, not a rumor.

Because an honest growth rate needs two valid samples taken a few days apart. The newest new Chrome extensions often have only one observation so far, so we display what exists and start scoring them the moment enough history builds up — usually within their second week on the chart.

High means both samples are well-timed and precise. Medium tolerates mild rounding or slight source differences. Low confidence — or a window that does not fit — keeps an entry out of the main ranking of new Chrome extensions rather than letting a noisy number climb the chart unchecked. The badge is visible on every row, so you can judge the evidence before you judge the extension — especially useful when comparing brand-new Chrome extensions side by side.

Once a day, automatically, with no manual curation step in between. The timestamp beside each chart shows the exact dataset snapshot it was built from, so you always know how fresh the new Chrome extensions you are looking at really are. The update itself is automatic — no one curates rows by hand, and no listing can be pushed up or pulled down editorially.

Chrome comes first because its store exposes the richest public signals. Firefox charts arrive in a later phase using the official Mozilla API, with metrics kept strictly separate — the same discipline we already apply to new Chrome extensions, extended to a second platform without ever blending the two, because mixed metrics make both numbers worse. Platform tabs will appear across the site, in all six languages, when that phase ships and its own methodology notes are published.

No. ExtensionRadar is an independent project that charts public store signals. Chrome is a trademark of Google; we simply track new Chrome extensions and their growth, and we link straight to the official listing for every tool so you can verify anything in one click.

Yes, with attribution. Growth history is built on Extension Tracker's public datasets (CC BY 4.0), and our own observations follow the same spirit — quote the charts, credit the source, and keep the confidence labels attached so the numbers stay honest in their new home. Full licensing details for new Chrome extensions data live on the methodology page.

Sampling follows value, not popularity alone: the newest discoveries and the fastest movers are checked most often, entries close to a scoreable window get topped up, and a small random control group keeps the baseline honest. Everything runs inside a fixed daily request budget, so the new Chrome extensions that matter most are always the best-measured, and coverage grows sustainably instead of aggressively.
