What This Section Covers
You typed "where to" into a search box because you want a place to go, right now, that is free, legal, and does not want an account or a card. This page points you to the most useful legitimate destinations for four quick checks: what your internet address is, how fast your connection is, whether a particular website is down, and where a plane is in the sky right now. None of the services listed here will ask you to sign up or pay, and every one of them is legal to use from a normal web browser.
Speedtest by Ookla, The standard speed check
Speedtest by Ookla is the most widely used internet speed test on the web. It measures your download speed, upload speed, and ping (latency) to a server you choose or that it picks automatically. The free version runs entirely in your browser and shows you results in a few seconds. The retrieved information does not document whether an account or payment card is required, but the service has been publicly available for years without either. It works globally, though the exact list of countries is not documented in the source material. If you want a speed test that most people recognise and that gives you a clear result you can compare with others, start here.
Fast.com, The simplest speed check
Fast.com is run by Netflix and does one thing: it measures your download speed. You open the page and the test starts immediately. There are no buttons to press, no servers to choose, and no account or payment card is mentioned in the retrieved information. It works on any device and in any country, though the source does not document a specific country list. This is the fastest way to see if your connection is slow right now, because you do not have to do anything except wait a few seconds.
CNMC’s official speed test, For users in Spain
If you are in Spain, the national telecom regulator (CNMC) provides its own speed test. The official page states it is a free, ad-free service for measuring real connection quality. It is developed by a public body, so the free basis is a public service, not advertising. The retrieved snippet does not mention account or payment card requirements, and it documents coverage only for Spain. This is the right choice if you want a test backed by a regulator and you are physically in Spain.
HostCry Is It Down, Check if a site is reachable from many countries
HostCry’s “Is It Down?” tool checks whether a public URL is reachable. The source says it checks from 114 countries, is completely free, and requires no account or credit card. You type a website address, and it tells you if the site is up or down from multiple locations around the world. This is useful when a site seems broken on your end and you want to know if the problem is yours or theirs. The free basis is the site’s own free monitoring service.
CheckWebs, A quick single-site status check
CheckWebs provides live HTTP status, response time, and diagnostics for a website you enter. The source says no account is required. It does not document country coverage, payment card requirements, or a licensing basis for free access. This is a simpler alternative to HostCry if you just want a yes/no answer about one site without seeing results from many countries.
Flightradar24, Live aircraft and airport tracking
Flightradar24 shows you where planes are in the air right now on a map. The retrieved information says the basic online functionality is available for free and includes aircraft and airport tracking, search, basic map settings, limited 3D tracking, and ads. The source does not document account or card requirements or country restrictions. Its free basis appears to be ad-supported access. If you want to see what flights are overhead or track a specific plane, this is the place. The free version is enough for casual use.
How to choose between them
Pick a speed test first if your internet feels slow. Use Speedtest by Ookla if you want a full result with upload and ping. Use Fast.com if you only care about download speed and want the test to start itself. Use CNMC’s official speed test only if you are in Spain and want a regulator-backed result. For checking whether a website is down, use HostCry Is It Down if you want to see results from many countries, or CheckWebs if you just need a quick status. For tracking planes, Flightradar24 is the only documented free option that covers live aircraft and airport tracking. None of these services require an account or a card, and all of them are legal to use from your browser.
