Hey,
I built Cloistr because I kept googling things like "free VAT calculator" and landing on pages with three sign-up walls before I could even use the thing.
Cloistr is a growing set of small, free tools for freelancers and small businesses — VAT calculator, invoice generator, freelance tax estimator, password generator, and more. No account, no email, no paywall — and it'll stay that way.
The site runs on ads to keep it free, not subscriptions or sign-ups.
Everything runs directly in your browser, so nothing you enter ever touches a server.
16 tools live so far, more on the way. Built solo — genuinely curious what you'd want to see next.
Love that everything just runs in the browser with no sign-up nonsense. Honestly the no-server approach is such a smart call for tools handling sensitive stuff like tax estimates and invoices, feels way more trustworthy than most alternatives out there.
Ran the VAT calculator and the break-even one without even making an account, which is honestly rare these days. Loved that nothing gets sent anywhere, took me 30 seconds to get a real number for a client quote.
Love that everything runs in-browser and there's no sign-up, makes it so easy to just pop in and use. One thing that would help me a lot: a CSV export option for the invoice generator so I can quickly import line items from a spreadsheet instead of typing each one out. Would be a great add to an already solid toolkit.
Love that everything runs locally with no sign-up. One thing that would make it even more useful for me is a built-in currency converter that pulls in live exchange rates for when I'm invoicing international clients, or at least lets me input custom rates and lock them to a specific invoice date.
Really love that everything runs in the browser with no sign-up, that kind of privacy-first approach is honestly so rare these days. One thing that would make it way more useful for me though is adding a simple export to PDF option for the invoice generator, since most clients expect a proper PDF attachment rather than just a print view. Would basically round out the whole freelancer workflow.
Took the VAT calculator for a spin and it was refreshingly fast, no flickering ads or surprise sign-up popups. The whole thing just feels respectful of your time.
