Sampler
Your own sync server across every device.
Maestro Sampler
Overview
Your own sync hub for all your devices.
Connect your phones, computers and browsers to one hub, with no account and no third-party server. Run your models on your own machines with Ollama, LM Studio or llama.cpp, and use them from any device. Data is end-to-end encrypted and stays on your own hardware.
Features
-
Running Models with llama.cpp
Run your models on your own machine with llama.cpp and native GPU acceleration, then use them from every device linked to your hub.

-
QR Code Connection
Link a new device in seconds by scanning a QR code. No account to create and no server in between.

-
Profiles
Keep separate profiles for each person or use, each one sealed end to end on your own hardware.

MCP server
A self-hosted MCP server.
Sampler can run an MCP server on your own hub, so Opera can reach the tools you connect to it without any data leaving your hardware. Nothing goes through a third-party server.
- Hosted on your own machine, under your control.
- Each member runs their own MCP servers, limited to their own folder on the hub.
- Called from Opera with a simple @mention.
