What verification unlocks
See how your site is discovered—and control what agents see.
- Control what agents see
Edit your listing description, tags, public contact details and additional llms.txt paths. Publish your terms for automated access, attribution and pricing.
- Make your profile eligible for search
A valid, listed, unblocked, verified profile can appear in our publisher sitemap and become eligible for search-engine visibility. Search engines decide what to index and rank.
- Appear in our llms-full.txt
Eligible verified publishers are listed by name, with their file links and summaries, in the service overview agents can read.
Free. No account registration, backlink or payment required. Public discovery remains available without verification.

# host-tools
> Free developer tools for everyday tasks — JSON, encoding, hashing, DNS and HTTP checks. No sign-up, no paywall, and nothing you paste into a local tool is uploaded.
Most tools process their input entirely in the browser, so nothing you paste is uploaded. The exception is `website-status`, which uses our server for the lookup and has a daily free limit. Each entry below states which mode it uses.
Every tool is documented on its own page with what it does, what it is not, and how it handles your data. Content is written for humans; this file is only an index.
