Free, like everything else
Missing something? Ask for it.
The best tools on this site exist because somebody needed them. Tell us what you were trying to do and we will look at building it.
Every tool here is free, and requesting one is free too. Requests go straight to the person who builds them, and the things people actually ask for tend to get built first.
What happens next
Your request lands in a real inbox, not a ticketing system. If it is something small and self-contained it may appear within a week or two. If it needs a heavy library or live data it takes longer, and occasionally something cannot be built at all — in which case you get a reply saying so rather than silence.
If you left an email address, you will hear back when it ships. If you did not, keep an eye on the full tool list, which grows every week.
How to make yours more likely to get built
Describe the job, not the tool. "I need to know how many working days until a deadline" tells us far more than "add a date tool" — sometimes an existing tool already does it, and sometimes the obvious tool turns out to be the wrong shape for the actual problem.
Small, sharply-defined tools get built fastest, because they can be made properly in one sitting. A request that would take an afternoon usually beats one that would take a month, even if the big one sounds more impressive.
Changes to existing tools count too
A missing unit in a converter, an option that would save you a step, a result shown in a format that is easier to paste somewhere else — these are usually the quickest wins of all, and they make the tool better for everyone who uses it afterwards.
The same goes for anything that looks wrong. If a number does not match what you expected, please say so. A wrong answer is the one problem worth dropping everything for.
Questions people ask
Does it cost anything?
No. Requesting is free and so is every tool on the site. There is no account, no queue you can pay to skip, and no paid tier.
Will you actually build it?
Often, yes. Requests go straight to the person who builds the tools, and things people actually ask for jump the queue — the roadmap is long, so a real request is the strongest signal about what to do next.
How long does it take?
It depends on the tool. Something small and self-contained can appear within a week or two. Anything needing a large library or live data takes longer, and a few things cannot be built at all — those get a reply explaining why.
What makes a good request?
Tell us what you were trying to do, not just the tool name. "I need to check how many working days until a deadline" is far more useful than "add a date tool", because it often turns out an existing tool already does it, or that the obvious tool is not quite the right shape.
Can I ask for a change to an existing tool?
Yes, and those are usually the quickest wins. A missing unit, an option that would save you a step, an answer shown in a more useful format — all worth sending.
Do I need to give my email?
Only if you want a reply. The request opens in your own email app, so you can see exactly what is being sent before anything leaves — and you can delete anything you would rather not share.
