What it does
Fighter cards
Record, ranking, Power Index, last five fights and next bout for any fighter named in a post, plus a jump to the opponent, the event or the tale of the tape.
Fight nights in the sidebar
Upcoming and live events in X's right column: who is in the cage right now and each result as it lands, spoiler-safe on live cards.
Search any selection
Right-click selected text on any website to look it up on UFCalendar. Typos are fine: "makacheb" finds Islam Makhachev.
The whole fight
Finished bouts show the result and the fight's own numbers; booked bouts show the tale of the tape.
Every major promotion
UFC, PFL, ONE, RIZIN, OKTAGON, KSW, BKFC and more, in 13 languages, nicknames and misspellings included.
Private by design
Names are recognised on your computer. The posts you read are never sent to us, and there is no tracking.
Your feed stays on your computer
The extension reads the posts on your screen locally to find fighter names. It only contacts ufcalendar.com to load a fighter's or an event's card, when you search a selection, or when you report a wrong match. No analytics, no browsing history, nothing sold.
Part of UFCalendar Pro
The extension is free to install and comes with a 7-day Pro trial, no card needed. After that, UFCalendar Pro is $5.99 a month or $59.99 a year, and the same subscription unlocks the iPhone and Android apps. Everything on ufcalendar.com stays free.
