Run OpenClaw without exposing your API tokens

·2026.04.18 11:27

Key point

Introducing Nilbox, which passes fake tokens and substitutes them with real tokens at the network layer.

Details

A runtime built to run OpenClaw safely.

The core problem is that no matter which sandbox you use, the real API token gets exposed to the agent as-is via environment variables.

Nilbox reduces this problem in the following way.

  • It passes a fake placeholder instead of the real token to the agent
  • Example: ANTHROPIC_API_KEY=ANTHROPIC_API_KEY
  • When an actual API call goes out, it's intercepted at the network layer and substituted with the real token
  • Even if the token leaks, all an attacker gets is a meaningless string

Additionally, it provides a managed Linux runtime that works on macOS, Windows, and Linux.

  • A Store offering one-click app installs
  • Support for full shell access
  • Downloadable at: nilbox.run
