YATME

What YATME is

YATME is a browser-based OpenTibia map editor for Tibia 15.00+ client data. It renders and edits OTBM map files using sprite data extracted from the Tibia client, and includes tools for tilemaps and entity placement. The project describes its inspiration as Remere's Map Editor and presents itself for map development and administration, including hosting alongside an OTS server.

To use the editor, you need asset files from a Tibia 15.00+ client and an .otbm map; related sidecar XML files are optional. The project provides Docker Compose and Docker run instructions, with the editor available at localhost port 8080 by default. Its Docker setup mounts client assets read-only and map files read-write, allowing saved map changes. At first startup, sprite sheets are converted from .bmp.lzma to PNG, and the converted cache persists across container restarts. YATME is MIT licensed and can be run locally as well as self-hosted. For local development, the README lists Node.js 22 or later as a prerequisite. The project is built with React 19, PixiJS 8, TypeScript and Vite.

Who it suits

YATME suits OpenTibia map creators and administrators working with Tibia 15.00+ client assets and OTBM maps. It is a fit for people comfortable running a self-hosted browser editor with Docker, or setting it up locally for development.

Limits

YATME requires asset files from a Tibia 15.00+ client and an .otbm map file. Local development requires Node.js 22 or later.

Getting started

1. Get asset files from a Tibia 15.00+ client.
2. Prepare an .otbm map file and, if needed, its sidecar XML files.
3. Choose the Docker Compose or Docker run instructions in the project README.
4. Mount client assets read-only and map files read-write in the Docker setup.
5. Open the editor at localhost port 8080 by default.
6. For local development, install Node.js 22 or later and follow the project instructions.

Verdict

Pick YATME if you need a self-hosted browser editor for OpenTibia maps and have the required client assets and OTBM files. Docker instructions provide a route to run it, and local development is also possible. Look elsewhere if you need an editor that does not depend on Tibia 15.00+ assets.
