Frequently Asked Questions
Are the tools really free?
Yes, all of them. Every tool in this list opens and works with no subscription, no credits and no cut-down versions. There is nothing to pay: the site pays for itself with advertising. The heaviest tools, such as the video upscaler or transcription, have a daily number of uses because each run takes up a real server, but they do not ask anyone for anything either.
Do I need to sign up to use the tools?
No, with no exceptions. Open the tool's page and get to work. You are not asked for an email, no wall appears halfway through, and you do not need an account to download the result.
How does Sitometro work?
Sitometro downloads the page the way a search engine crawler would and runs it through about eighty checks split into nine areas: server speed, SEO, design, technical aspects, marketing, sustainability, privacy, accessibility and readability for AI. It returns a score from 0 to 100, where the target is 90, with the problems found and the order in which to tackle them. The report can be downloaded as a PDF.
Can I use the tools for my clients?
Yes. The tools suit agencies, freelancers and consultants: you can use them to analyse your clients' websites, prepare professional quotes and produce detailed reports.
Is the data I enter safe?
The data is processed in real time and is not stored on our servers. Some tools save data locally in your browser to make them easier to use.
How often are the tools updated?
We keep the tools updated so they stay accurate and reliable. Databases such as the Wappalyzer one behind Tech Radar are updated every month with the latest technologies.
Can I request new tools?
Yes. We are always looking for new ideas. Write to us and we will look at your suggestion.
Do the tools work on mobile?
Yes, all the tools are designed for mobile devices. You can use them on a smartphone or tablet as easily as on a desktop computer.
Do the files I upload stay private?
Many tools work inside the browser, so the file never leaves the device. Where processing on our server is needed, as with audio and video, the page says so plainly.
How do I find the right tool?
The search box at the top looks by name or by what you need to do, and the catalogue is split by area: tax, images, documents, text, development, health and finance.
Does my data stay private?
Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.
Do you store what I enter?
No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.
Do you profile me? Are you GDPR compliant?
We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.
If it is free, how do you make money?
From advertising, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
Pick a tool and use it right away.
The tools on this page are free, and almost all of them work without an account.
