WiFi tools for network engineers
A free toolkit for planning, deploying, and debugging WiFi networks. Every tool runs in your browser, with no sign-up and nothing stored. Built by the team behind Purple's guest WiFi, captive portals, and location analytics.
IP addressing and subnetting
Plan address space, subnets, and DHCP scopes before you touch a switch.
DNS and domains
Resolve records, check propagation, and inspect domains and addresses.
DNS record lookup
Query A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV and PTR records for any domain.
DNS propagation checker
Compare a DNS record across Google, Cloudflare, NextDNS and AdGuard resolvers.
WHOIS domain lookup
Check a domain's registrar, expiry, nameservers and DNSSEC status via RDAP.
What is my IP address
See your public IP, IP version, approximate country, reverse DNS and browser details.
WiFi deployment
Size and shape the wireless network itself.
Access point calculator
Estimate how many wireless access points your venue needs from area and user density.
Beacon and SSID overhead calculator
Estimate the airtime your SSIDs and beacon frames consume so you can prune wasteful broadcast overhead.
WiFi channel planner
Pick non-overlapping 2.4 and 5 GHz channels for your access points to cut co-channel interference.
Connectivity and performance
Measure speed, latency, and DNS response from where you are.
Internet speed test
Measure download and upload throughput from your browser, with no app or plugin required.
Latency and jitter test
Measure round-trip latency and jitter to gauge connection stability for calls, video, and gaming.
DNS speed test
Compare how fast public resolvers such as Cloudflare, Google, and NextDNS answer from your location.
Security and access
Certificates, RADIUS, walled gardens, and client-privacy controls.
SSL certificate checker
Verify a site's certificate issuer, expiry, days remaining, chain trust and SANs.
Walled garden generator
Generate pre-authentication whitelists and ACL rules for Cisco Meraki, Ubiquiti UniFi and Aruba.
RADIUS setup guide
Generate WPA2 and WPA3 Enterprise (802.1X) configuration profiles for cloud identity providers.
MAC randomization simulator
Simulate the impact of MAC address rotation on visitor analytics and data integrity.
Utilities
Everyday encoding, hashing, and credential helpers.
Password and passphrase generator
Create strong random passwords and memorable passphrases with a live entropy meter.
Encoder, decoder and hash generator
Base64, URL, HTML and hex encode/decode, plus MD5, SHA-1, SHA-256 and SHA-512 hashing.
WiFi QR code generator
Create a scannable QR code that joins a WiFi network, generated entirely in your browser.
MAC address lookup
Identify the hardware vendor behind any MAC address from its OUI prefix.
HTTP header checker
Inspect the response headers and security headers any URL returns.
Planning a network you actually have to run?
These tools plan the network. Purple layers guest onboarding, captive portals, and location analytics on top of it, across Cisco Meraki, HPE Aruba, Ruckus, and Juniper Mist.
