- Hosting Model
- Local or hosted (your machine or their cloud)
- Platforms
- webself-hosteddocker to self-host
- Installation
- Use the hosted web app with your API keys, or self-host with Docker/Vercel
- Operational Setup
- The free hosted app is immediate, but it does not include model usage: the user must bring provider API keys and understand provider billing
- Where Your Data Lives
- The open app stores chats and settings locally in the browser by default; hosted Pro adds synced cloud storage, and model requests go to whichever provider the user configures
- The Catch / Trade-off
- It can fan one prompt across models, but you must provision and bill each provider separately and its interface is less focused on clean answer comparison than Admix.
