Overte vs ZEP

Overte is open-source software for creating, hosting, and exploring virtual worlds through VR or desktop experiences. Users can meet in worlds and attend or host live VR events; world creation and editing can be collaborative. VR support includes body tracking, and a single world can scale to up to 500 users. JavaScript scripting can add games, interactables, interface elements, and custom applications. Users can import 3D objects, and the software includes spatial audio and physics powered by the Bullet engine. Overte is free under the Apache 2.0 license, with Linux and Windows releases, source code, and Docker images listed for download. It can be self-hosted, including on a home server; the project says there is no central authority and no account is required. Overte e.V., a non-profit association registered in Germany, is behind the project, though membership is not required to use or develop the software. Community discussion is available on Matrix and Discord, with the Matrix Space bridged to Discord. Documentation covers security for Interface and servers, including crash reporting and asset security.

ZEP is a web service for virtual spaces used for online gatherings, offices, bootcamps, and events. People can connect through video, reactions, chat, and spatial audio; rooms accommodate up to 20 participants, and guest access and screen sharing are supported. The Map Editor lets users place objects, add links or videos, and design maps. ZEP’s site presents ZEP, ZEP QUIZ, and ZEP SCHOOL as separate services. In ZEP QUIZ, teachers create quizzes, students join as avatars, and results are available in real time. QUIZ AI can generate questions from a topic or uploaded class materials and create answer choices. Students can join in a browser using a QR code or entry code, without installing an app. The displayed quiz plans cap concurrent users at 200. ZEP School offers spaces for a school’s teachers and students, with tailored estimates, administrative documents, and multiple payment methods for schools. The Free plan costs nothing and has limited access to premium maps and question types. ZEP lists no mobile apps.
