The original edubart/otclient repository was created on November 18, 2010. Its README describes an alternative client for OTServ that aims to be complete and flexible, with game-interface behavior written in Lua and appearance controlled through OTML. The public-repository date is used here because the original line did not maintain a conventional release history.

OTClient was designed as both a playable client and a framework. The modular architecture allowed server owners to replace interface elements, add modules, expose new client-side features, and target platforms that were difficult to reach with the official client. Later forks inherited that flexibility while adding protocol support, rendering changes, mobile work, updaters, and server-specific systems.

Evidence classification: Repository-backed. The date shown in the reference box is phrased to match what the surviving source actually proves.

The first era focused on replacing hard-coded client UI with Lua modules and style files. That made custom health panels, hotkeys, game windows, effects, language packs, and protocol extensions practical. It also created a maintenance burden: every server's fork could diverge in packets, modules, and assets.

The modern era is defined by forks such as OTClient Redemption. Its public line adds newer protocol support, performance work, shaders, attached effects, Android and web build paths, and integrations with TFS or Canary. There is no single universal OTClient binary; the exact repository, commit, assets, and server protocol form one release.

Players encounter OTClient as a server-provided branded client. Owners use it to control login endpoints, UI layout, client modules, asset loading, protocol features, updater behavior, mobile support, and visual systems not available in the standard client.

Developers use the Lua module layer to build windows, hotkeys, status displays, task interfaces, shops, effects, and server-specific features. The C++ layer handles rendering, networking, input, asset decoding, and the lower-level game API.

The correct player workflow is to obtain the client from the verified server domain and verify checksums or signatures when supplied. The correct owner workflow is to pin a source commit, record required assets and protocol features, and test login, movement, combat, containers, chat, effects, reconnects, and updates as one package.

OTClient changed what an Open Tibia server could look and feel like. Lua-driven interface modules, shaders, animated textures, transparency, attached effects, mobile ports, and custom protocol messages let projects build experiences that were impossible with a simple IP changer.

Its fragmented lineage is equally notable. Community discussions about which repository is the main OTClient are not merely naming disputes; they reflect real differences in protocol support, stability, features, and maintenance. A good directory must record the exact client lineage used by each server.

Verify the repository and commit, supported protocol range, required DAT/SPR or modern assets, server feature flags, encryption or login changes, updater source, build instructions, and open security issues. A build made for one server should not be assumed safe or compatible with another.

Owners should remove embedded secrets, restrict update origins, sign distributions where possible, and provide a transparent download path. Players should avoid repacked executables from videos, file mirrors, or unofficial Discord messages.

This page separates a confirmed public date from an assumed development date. Its release statement is: Original public repository created November 18, 2010.

The recorded lineage is Created by edubart; extended through multiple community forks including OTClient Redemption. The source links preserve the repository, release page, official documentation, publisher archive, or contemporary discussion used to support that description.

Project activity, compatibility, and security can change. Readers should use the linked upstream repository or official documentation to confirm current support before adopting the resource.
