Permission to use, copy, modify, and/or distribute this software for any
purpose with or without fee is hereby granted, provided that the above
copyright notice and this permission notice appear in all copies.
THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES WITH
REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF MERCHANTABILITY

INDIRECT, OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES WHATSOEVER RESULTING FROM

PERFORMANCE OF THIS SOFTWARE.Why ISC?
The ISC License is functionally equivalent to the MIT License but with simpler language. It is approved by the Open Source Initiative (OSI) and is the default license used by npm and OpenBSD.
It was chosen for VMark because:
- Simplicity — easy to read and understand
- Permissiveness — no restrictions on how you use the software
- Compatibility — works with virtually all other open-source licenses
Third-Party Software
VMark is built on open-source software from many authors: Rust crates, npm packages, and components compiled into them, such as Graphviz and the Node.js runtime inside the MCP server. Their licenses (MIT, Apache-2.0, BSD, ISC, MPL-2.0, EPL-2.0 and others) ask that their notices accompany every copy of VMark.
Every VMark build includes the full text of those notices. To read them, open Settings → About and click Third-party notices — the file opens in your default text viewer.
The notices are generated from the exact dependencies of each release, so they match the version you have installed.
