Knapsack OpenClaw App - A safe & simple OpenClaw / Moltbot / Clawdbot app for Mac

Knapsack is an open-source desktop client for OpenClaw / Clawdbot / Moltbot — the AI agent that controls your browser and acts on your behalf. Giving AI that power is dangerous without guardrails. Knapsack adds them: sensitive path blocking (SSH, credentials, .env), prompt injection defense, tool loop limits, mandatory confirmation before sending messages or spending money, and sandboxed scripting. Also bundles a private notetaker, email autopilot, and multi-LLM support. Local/open source.
