Tim Baek

Open WebUI

Baek started the Open WebUI repository with its initial commit on 2023-10-06, and the README credits Timothy Jaeryang Baek as its creator. The project describes itself as a self-hosted AI platform that can run entirely offline and works with Ollama and OpenAI-compatible APIs, so the same interface can serve local and cloud models. Its license notice is held by Open WebUI Inc. and names Baek as the creator.⁴³⁷

The project's documentation says its team is led by Baek as creator and founder, supported by company staff and community contributors. Baek's own homepage says Baek is currently building Open WebUI, described there as an open, local and decentralized AI interface, and Baek continued to author commits to the repository in October 2026.¹²⁵
