LiMP products and tools
Small, useful tools that run right in your browser — no install, no sign-up. Check whether your VPN really works, what the internet can see about you, and whether anything is leaking. We log and store nothing.
Or pick a category to see the tools for a specific task:
Network & VPN
My IP address & footprint
Your public IP address, city, provider and network (ASN), browser fingerprint and WebRTC. Plus a lookup for any domain or IP.
OpenIs my VPN working
Check your public IP and leak signals (WebRTC, IPv6, time zone) with a plain answer: is the VPN working right now, and what does each signal mean.
CheckDNS leak test
Which DNS servers handle your queries: resolver address, provider and country, plus a verdict on whether DNS leaks outside your VPN tunnel.
Run testInternet speed test
Download and upload in Mbps, ping and jitter in about 25 seconds, a verdict for 4K, calls and gaming, and latency to LiMP servers.
Start testInternet stability test
Ping, jitter and packet loss across 25 quick probes with a plain verdict: is your connection good enough for calls, gaming and video. Right in your browser.
Run testWi-Fi security check
Is this Wi-Fi safe: DNS spoofing, HTTPS interception, page injection and WebRTC. A five-point traffic light and a clear answer on logging in to your bank and email.
Check networkWebsites & links
Is a site down for everyone or just me
Check a site from an external vantage point and from your own browser: HTTP status, response time and a plain verdict — is it down for everyone or only for you.
CheckWebsite availability from different countries
Does a site open from Russia, Europe, the USA and Asia: 8 check points, DNS, TCP and HTTPS stages for each, and signs of access restriction from Russia.
CheckLink and website phishing check
Domain age, certificate, redirects, brand lookalikes and the Phishing.Database list. Addresses are shown as text, no files are downloaded.
Check a linkDependency audit & SBOM
Upload a lock file or manifest: known vulnerabilities (OSV), licenses, deprecated packages, cloud SDKs and a CycloneDX SBOM. Files are parsed in your browser.
CheckPasswords & breaches
Password generator
A strong password or passphrase with no signup: length, character sets, strength and crack-time estimate. Generated in your browser — nothing is sent or stored.
GeneratePassword strength and leak check
Password strength and time to crack with tips, plus a breach check against Have I Been Pwned. Your password never leaves the browser: only 5 hash characters are sent.
CheckEmail breach check
Whether your email or a website appears in known data breaches: date, number of accounts, what data leaked and what to do. We don't store the address.
