Hardware requirements
Open WebUI
Open WebUI itself has no GPU requirement — it is a frontend. The GPU requirement depends entirely on the model you connect. For small models (7B-8B), you can run on CPU only with 16 GB system RAM.
LibreChat
LibreChat itself needs no GPU. Docker host minimum: 4 GB RAM (2 GB MongoDB + 2 GB app). For local models, add GPU per model requirements. Runs fine on a $5/month VPS with cloud APIs only.
