Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
AUTOMATIC1111 Stable Diffusion WebUI
- Development pace has slowed; Forge fork is now more actively maintained
- Requires a capable GPU (8 GB VRAM minimum for most modern models)
- No built-in user accounts or API key auth for multi-user deployments
Onyx Community Edition
- Self-hosted stack is resource-heavy (Postgres + Vespa + Redis + multiple services)
- Some enterprise connectors and features are gated behind the paid cloud tier
- Initial connector sync for large knowledge bases can take hours
- SAML/SSO configuration requires manual setup and is not well-documented for self-hosters
