As answered by people managing HetrixTools and srvScripts.
srvScripts's answer:
It puts 162 free server-admin tools, 400+ tested guides and 39 open-source scripts in one place, with no sign-up. Many tools run entirely in your browser, so nothing you paste is uploaded, and each tool page says where its checks run. Every guide and script states how it was tested and on which versions, and every script shows a SHA-256 checksum plus clear backup and undo steps before you run it.
srvScripts's answer:
WordPress and PHP on a LiteSpeed server with MariaDB; plain JavaScript for the in-browser tools; Bash and PowerShell for the scripts; and a self-hosted speech-to-text service for call-recording transcription.
srvScripts's answer:
Most DNS and email-check sites give you one lookup at a time and push you to sign up. srvScripts is free without an account and handles bulk work: up to 256 IPs or CIDR ranges against 33 blacklists at once, an SPF checker that follows the full include tree and counts lookups, and IPv4 and IPv6 subnet tools. When a check finds a problem, it links to a step-by-step fix guide written for cPanel, DirectAdmin, Linux or Windows Server, so you can go from "what's wrong" to "fixed" on one site.
srvScripts's answer:
Server administrators, hosting providers and web agencies who look after cPanel, DirectAdmin, Linux or Windows servers, plus developers and IT staff who need to fix email delivery, DNS, SSL or blacklist problems quickly.
srvScripts's answer:
srvScripts was started by a working server administrator who runs hosting servers for companies and agencies. The same checks and fixes came up again and again: mail going to spam, an IP on a blacklist, DNS not updating, SSL errors after a migration. The useful tools were scattered across many sites, often limited or behind sign-ups. srvScripts collects them in one free place and adds the tested guides and scripts that go with them.
