Terms of Service
By using LinuxCLI, you agree to the terms below. This is a small, free service run by one person — these terms exist mainly to keep it usable for everyone, not to bury you in legal text.
Acceptable use
Use LinuxCLI only against hosts and domains you own, operate, or are otherwise authorized to test — for example your own infrastructure, or public DNS/WHOIS records that anyone is allowed to query.
Do not use LinuxCLI to probe, harass, gather information about, or otherwise interfere with third-party systems without authorization. This includes using it as a building block for automated reconnaissance against targets you don't control.
Only the fixed set of read-only diagnostic tools offered on the site is available. There is no active port scanning (nmap, masscan, etc.), no file upload, and no persistent shell — attempts to work around these limits (e.g. via crafted arguments) are themselves a violation of these terms, separate from whatever the command validator already blocks technically.
Rate limits and enforcement
Usage is rate-limited per IP address (and per API key, if you generate or register one). Limits exist to keep the service available for everyone, not to meter a paid product — there is currently no paid tier.
Accounts or IP addresses used abusively — to violate the acceptable use section above, to circumvent rate limits, or to attack the service itself — may be rate-limited further or blocked, without notice, at the operator's discretion.
No warranty, no uptime guarantee
LinuxCLI is provided as-is, free of charge, with no uptime or availability guarantee. It may be slow, rate-limited, partially unavailable, or discontinued at any time without notice. Do not build anything business-critical on top of it.
Command output comes from real, live tools (dig, curl, whois, etc.) run against real, live infrastructure you point them at — LinuxCLI does not guarantee the accuracy, completeness, or timeliness of that output, only that it faithfully runs the command you typed and returns what the tool itself produced.
