Internet tools
Velohost Tools
Privacy-first diagnostics and utilities designed to expose how the internet actually behaves — without abstraction or scoring.
Each Velohost tool focuses on a single observable behaviour — DNS resolution, certificate state, protocol responses, or encoding formats. The goal is clarity, not judgement.
For framework-level integrations and automation, see the Velohost plugin library .
Infrastructure & DNS
Inspect DNS records, resolution behaviour, certificate state, propagation timing, and core infrastructure signals.
DNS lookup
Perform live DNS queries to retrieve authoritative A, AAAA, MX, TXT, SPF, DKIM, DMARC and related records.
WHOIS lookup
Check domain registration details including registrar, registration dates, expiry, and authoritative name servers using WHOIS and RDAP data.
IP geolocation
Identify the network owner, ASN, and approximate geographic region associated with an IP address or domain.
SSL certificate checker
Inspect SSL/TLS certificates to verify validity, expiry, issuer, and supported security protocols.
HSTS status checker
Check whether a domain enforces HTTP Strict Transport Security (HSTS) and how browsers will treat HTTPS enforcement.
Ping test
Test network latency and packet loss to a remote host using ICMP echo requests.
Traceroute
Trace the network path packets take to reach a destination and identify latency at each hop.
TTFB checker
Measure Time To First Byte (TTFB) to assess backend responsiveness and server performance.
Broken link checker
Scan a website for broken internal and external links that may impact usability and SEO.
Canonical URL checker
Inspect canonical tags to verify correct URL consolidation and prevent duplicate content issues.
Open Graph checker
Preview and validate Open Graph metadata used by social platforms when sharing links.
SERP preview
Preview how a page title and meta description may appear in search engine results.
Meta length checker
Check title and meta description lengths against common search engine display limits.
HTML size checker
Measure total HTML document size to identify performance or rendering issues.
Favicon checker
Detect and validate favicons used by a website across browsers and platforms.
CDN detector
Detect whether a website is using a Content Delivery Network (CDN) and identify the provider.
Sitemap extractor
Extract and inspect URLs from XML sitemaps, including sitemap index files.
User agent parser
Inspect and parse user agent strings to identify browsers, operating systems, and devices.
Encoding & Utilities
Lightweight helpers for timestamps, encoding formats, and low-level data representations used across the web.
Base-64 encoder / decoder
Encode and decode Base-64 values using UTF-8. Commonly used for HTTP authentication, APIs, and data transport.
URL encoder / decoder
Encode or decode URL components to safely transmit data in query strings and paths.
HTML encoder / decoder
Encode and decode HTML entities to safely display or process markup.
JSON validator
Validate and format JSON to ensure correct structure and syntax.
JWT decoder
Decode and inspect JSON Web Tokens (JWT) to view headers, payload claims, and expiry information without verification.
Unix timestamp converter
Convert Unix timestamps to human-readable dates and back with second or millisecond precision.
ISO 8601 converter
Convert and validate ISO 8601 date and time strings across time zones.
UUID generator
Generate RFC 4122 compliant UUIDs for identifiers and database keys.
Random string generator
Generate secure random strings with configurable length and character sets for passwords, tokens, API keys, and identifiers.
Password strength checker
Evaluate password strength based on length, entropy, and common attack patterns.
