Community or commercial package indexes are not operated by this project unless explicitly listed here - verify any third-party package against sources and checksums you obtain from ilusm.dev.

Acceptable use policy

You may use ilusm to:

  • Build applications, scripts, and services
  • Conduct authorized security testing on systems you own or have explicit written permission to test
  • Research and learn about security techniques in controlled environments
  • Participate in CTF competitions and bug bounty programs within their stated scope

You may not use ilusm to:

  • Access, modify, or disrupt systems without authorization
  • Conduct attacks against infrastructure, services, or individuals
  • Create malware, ransomware, or other harmful software for deployment
  • Violate any applicable law or regulation

Violation of this policy may result in legal liability. ilusm contributors are not responsible for misuse of the software.

Privacy

ilusm.dev does not collect personal data. The site does not use cookies, analytics, or tracking. The Loveshack runner executes entirely in your browser - no code is sent to any server.

No warranty

ilusm is provided "as is" without warranty of any kind. The language is under active development. APIs may change. The self-hosting bootstrap is a work in progress. Do not use ilusm in production systems without understanding its current limitations.

  2. Document the vulnerability with reproduction steps.
  3. Contact the maintainers through the channel listed on the download page.
