Invite People to a House Party Without Posting It

Four people, a borrowed amp, and a basement that smells faintly of a washing machine. That's the gig. Friday, starts whenever the drummer's lift turns up, and if forty strangers arrive we are all going to have a genuinely bad evening.

So you don't post it anywhere. Obviously. Which puts you back to sending the address to eleven people individually, three of whom will lose it, one of whom will ask again at ten on Friday night while standing on a street that looks like every other street.

There's a middle setting nobody uses

The instinct is that a thing is either announced or it's a group chat, and there's nothing in between.

There is something in between, and it's boringly simple: a page that genuinely exists — real link, opens in any browser, has the photos and the time and the door on it — that just isn't listed anywhere. You can't browse your way to it. Not on a map, not in a feed, no search turns it up. It's there because you made it, and it's reachable if somebody sent it to you.

In Blinko Spots that's a Beacon with one toggle left alone. Show on nearby map is opt-in and off by default. You have to actively switch it on before anyone browsing the area can find the thing. Leave it, and they can't.

That default is the right way round, and it's worth knowing it's the way round it is, because most things you publish anywhere else start from the opposite assumption.

Now the part you actually need to take in

A link is not a lock.

Anyone holding the link sees the whole page. Photos, the time, the exact address, directions to the door. Not an approximate area — the address. That is deliberate and it has to be, because your mates need to find the basement and a vague circle on a map is no use to anyone at half past nine in the rain.

Which means the whole security model here is who you send it to, and what they do with it next.

The map coarsening protects you from a stranger browsing the neighbourhood. It does nothing at all about a screenshot forwarded into the year group chat at eleven o'clock. Nothing about a link pasted into somebody's story. Nothing about the friend of a friend who was sent it "just in case", who has met you twice, and who is a lovely person with three hundred contacts.

So say it. Out loud, in the chat, in the same message as the link: don't forward this. It's an unglamorous sentence and it does more work than any setting in any app.

And judge the send before you make it. A link that reaches thirty people you know well is a different object from a link that reaches thirty people, six of whom you couldn't pick out of a queue. The app can't tell those apart. You can.

Sending it

You can paste a bare link, and sometimes that's all you want. But the share sheet builds a card instead — the title, the time window, the short link, and a code big enough to scan off someone's screen.

If the people you're sending it to are in a Blinko group with you, the card goes straight into that chat and they can follow it from there. If they're not, the same card goes out through your phone's normal share sheet into whatever you actually use, as an image with a link attached.

Either way it's one send and it answers everything. You stop being the address service.

It isn't only gigs

The shape fits anything where everyone welcome is the wrong sentence.

The two-in-the-morning revision thing in the library that stays open — third floor, the good desks by the window, we're here till it gets light. You want the six people doing the same module. You do not want the cohort.

A birthday in a flat with a landlord who reads noise complaints as a hobby. A film night. A leaving do that is genuinely just the twelve of you. A seven-a.m. run that four people have said, in writing, that they will do.

All of them: a page that answers every question, sent to a bounded list, with nothing about it discoverable by anyone else.

When it moves rooms

Basements flood. The gig relocates to Tom's because his housemates have gone home for the weekend.

You edit the page and it's correct from then on. Nothing is sent to anybody — people following it see the change the next time they open the app, and everyone else finds the page right whenever they open the link. Quieter than a broadcast, and it means you can correct the page six times without six phones going off in six pockets.

If it's the kind of night that properly moves — starts in the flat, ends up somewhere down by the water — a Live Beacon does the pin-and-re-pin version of the same idea, and it's honest about being a snapshot rather than a trail.

Afterwards

You end it and it stops being live. It doesn't vanish — it settles into the past ones, so in a month when you're trying to remember what date that gig was, it's there.

Blinko Spots is free. Every feature, no tiers.

Two neighbouring cases, if either is more your problem. When you do want strangers — a garage sale, a park thing, the whole extended family — the same page works the other way round. And when the thing recurs rather than happening once, the page collects followers between sessions and the regulars end up somewhere else entirely.

Put the sentence in the message when you send the link. Don't forward this. Then go and move the sofa.
