License

Atbash has two parts with different licenses: the client software you install and run alongside your agents, and the hosted Atbash service it connects to.

Client software — Apache License 2.0

The following client software is open source under the Apache License, Version 2.0:

• Atbash SDK
  atbash-sdk
• Atbash CLI
  atbash-cli
• Agent framework plugins
  OpenClaw, Hermes, Claude Code, Codex / ChatGPT, MCP, LangChain, LangGraph, AutoGen, Eliza
• Atbash Connect
  atbash-connect
• Atbash Sandbox
  atbash-sandbox

The license applies per repository. Each repository's LICENSE and NOTICE files are authoritative, and its third-party notices list the open source components it includes. Versions published before the move to Apache-2.0 remain available under the license they were released with.

The Atbash service — proprietary

The hosted Atbash service, including the judge, the verdict chain, the dashboard and the on-chain contracts, is proprietary software of Atbash Technologies Ltd. All rights reserved. Your use of the service is governed by the Terms of Service. The Apache-2.0 license on the client software does not grant any rights to the service.
