Open Source Free Trial

Local-first, self-hosted runtime for auditable AI agent sessions

SandBase Harness is a self-hosted runtime and MCP bridge for running AI agent sessions on your own machine.

It provides sandboxed sessions, credential handling, memory, approvals before tool calls fire, and an audit and replay log of what an agent did. A local console ships with it.

Sandbox backends are configurable, so the isolation layer can be swapped for the one that fits your environment. Apache-2.0 licensed.

Pricing: Free
