About League Of Data Base
League Of Data Base is a free League of Legends encyclopedia: every champion, item, rune and summoner spell, for any patch, in 21 languages.
What this site is
League Of Data Base is a reference site for League of Legends game data. It publishes the game's own files — champions, items, runes and summoner spells — as readable pages you can browse, filter and compare. Every value comes from Riot's official Data Dragon distribution, so what you read here is what the game ships, not an estimate or a community guess.
Who it is for
Players checking a champion's abilities or an item's cost between games; theorycrafters comparing values across patches; content creators who need exact numbers; and developers who want the same data through an API. Nothing here is behind a login — reading requires no account.
What you can do here
Browse the full codex
Detail pages for every champion (abilities, skins, base statistics, lore), item (cost, statistics, build path), rune path and summoner spell, each list with instant search and filters.
Travel across patches
Switch to any Data Dragon patch and read the site as it was on that version. Historical pages keep their own addresses, so a link to a past patch stays accurate forever.
Read in your language
Interface and game data are available in the 21 languages Riot publishes — from English and French to Korean, Japanese, Arabic and both written forms of Chinese.
Create and share builds
Assemble item builds step by step in the armory editor, then share them with a link. Builds can be voted on, and a public profile collects the ones you publish.
See what is being consulted
The trends page ranks the champions, items and runes most looked up on the site — a read on community attention, not on match statistics.
Query the data programmatically
A JSON REST API exposes public profiles, shared builds and consultation trends, with a free tier and paid credit packs for heavier use.
Install it and keep browsing
The site is an installable progressive web app: add it to your home screen and pages you have already visited stay readable without a connection.
Where the data comes from
Every value on this site is read from Riot Games' Data Dragon distribution, the official static export of League of Legends game data, completed by Community Dragon for skin chromas. Nothing is hand-edited: the site is a reader, not an editor.
Who runs it
League Of Data Base is an independent project built and maintained by a single developer and funded by voluntary donations. It carries no advertising and sells no personal data.
The source code is public on GitHub.
