For local businesses.

A quiet way to send short updates to the customers who actually want them. No algorithm to fight. No ad spend. No fake followers.

The idea

You run a barbershop, a café, a comic shop, a salon, a yoga studio, a little bookstore. You'd like to tell your regulars when something matters — a same-day opening, a new arrival, a closure on Tuesday — without paying Instagram to show your post to the people who already follow you.

On instruments, your updates only reach the customers who opted in by entering a code you handed them. Nothing is public. Nothing is boosted. Nothing is suppressed. The people who care, see it.

How it works

1. Sign up as a business. Free. Email confirmation, no approval queue.
2. Generate join codes. Three are created automatically. You can revoke and rotate any time.
3. Hand the codes out. Print one on the counter card. Add it to receipts. Text it to your texting list. Tape it next to the register. You choose how it spreads.
4. Post when you have something to say. Short text. A photo if it helps. That's it.

What you can post

• Today's special
• A last-minute opening
• A holiday closure
• A new arrival or seasonal menu
• A note that you're running behind, or that there's no wait
• A photo of the new dog, the new sign, the new espresso machine

Text-only posts are fine. Not everything needs a picture.

A few real examples

What's different

• Code-gated, not public. Only people you handed a code to can see your posts. You decide where the codes live.
• No comments. Posts go out one-way. You're not signing up to moderate a comment section.
• No follower count race. You'll see how many subscribers you have, and that's it — no rankings, no leaderboards, no "engagement rate."
• No algorithm. Subscribers see your post in the order you wrote it, in their feed alongside posts from family and friends.
• No ads, ever. instruments doesn't sell promoted posts. There's nothing to outbid.
• You won't see anyone's timeline. Business accounts can post but never browse — by design. You're not pulled into the feed game.

What it's not for

Reaching new customers. instruments has no search, no directory, no public discovery. If somebody doesn't have your code, they can't find you here. For acquisition you'll still want signage, word-of-mouth, and whatever other channels you already use. instruments is for the people who already came in.

Cost

Free. There's no business model that depends on charging you, because there's no business model that depends on showing your post to fewer people than chose to subscribe.
