Your favourite name is taken. That is not the moment to get creative with the spelling.
This is what most people do next, and every one of these moves makes the name worse: drop a vowel, swap a letter for a lookalike, tack on a number, add an x at the end. The name still looks like yours on a slide. It stops working the moment someone hears it and tries to find you. Every mention becomes a spelling lesson, and a few listeners land on the original name instead, which is someone else's business.
There are only a few rescues that actually keep a name usable, and they all use real words.
Add a word that says what it does. A short verb in front, like get, try, or use, or a word for the thing itself, like app, studio, or lab. It has to read as a phrase a person would say, not a password.
Add a word that says who it is for. The audience, the place, the craft. If the extra word narrows the name to the people you actually serve, it is doing work. If it is just filler to dodge a taken domain, it is not.
Flip the order, or shorten it honestly. Sometimes the second word first is a better name than the original. And a shorter version of the name, cut at a natural break, beats a longer version held together with a hyphen or a number.
Then run every variation through the same checks as a fresh name. Say it out loud. Ask someone to spell it after hearing it once. Check the domain and the handles together, before you commit. A variation that fails any of those is not a rescue, it is the same trap with extra steps.
And if no variation passes, let the name go. That is the hardest part, and it is also the cheapest. A name you can actually own, found in an afternoon, beats a name you have to defend and spell for the next five years.
That is the part of naming I built NamerGuide around. Describe what you are building and it shows you name candidates with domain and username availability checked together, with the date each check was made, so you can see what was actually verified and when. Run your variations through it before you commit, not after.
