RBLXDB is an independent Roblox reference and tracking website that brings together game data, asset IDs, catalog information, working codes, and live player statistics. Its database covers thousands of games, music IDs, decals, catalog items, and codes, with figures measured, checked, and dated. RBLXDB says it reads tracked games hourly, preserving player-count history to show what is popular and what is changing.

Visitors can look up music, decal, model, mesh, game, and place IDs; browse catalog items, avatar accessories, bundles, limiteds, free items, and outfit ideas; and explore game codes, promo codes, and boombox codes. For game discovery, the site provides live player counts, rankings, charts, trending games, update feeds, milestones, comparisons, filters, and watchlists. It also offers tools such as an ID finder, user lookup, account-value calculator, username utilities, and Robux conversion, alongside guides, quizzes, and an API. RBLXDB invites users to help verify codes and provides a free feed for Discord communities.
