Alive in real time
The world, its creatures, its events: everything reacts to your time. Midnight is another story.
Always with you
Small and light enough for your keys. Trappet goes where you go.
Online or off the grid
No signal? Keep exploring. Trappet plays fully offline and catches up when you’re back.
Made to be modded
Fully open to mods. Add new creatures, places and stories, and share them with everyone.
What is Trappet?
A tiny game console.The world outside isthe cartridge.
Trappet is small enough to hang from your keys, and you play it by walking. Wherever you stand, the streets, rivers and fields around you become the map, and someone already lives there.
01 · The screen
A window onto right here.
Every cell is a patch of real ground around you, drawn as a tile. You’re always the one in the middle.
02 · Buttons & radios
Three buttons. Three radios.
Three buttons on the side and a touch display: all you need to greet a stranger, explore ruins or milk a cow. Inside, GPS puts you on the map, and Wi-Fi and Bluetooth keep you in sync with your friends.
03 · Built to go out
Comes along anyway.
Small enough for a keyring and it charges over USB-C, so it’s already in your pocket when you head out.
Every walk, a different world.
Take it to the river, the village or the olive groves and the screen follows the ground. These are real spots in the Ebro valley, and you’re about to explore it.
* Colours are a sketch. Nothing’s decided yet.
How it works
The real worldis the map.
Trappet reads the land around you from OpenStreetMap (water, woods, fields, villages) and redraws it as a grid of pixel-art cells, each about 150 metres across. You're always standing in the middle one: walk out here, and you walk in there.
The locals
Go outside.It’s alive out there.
Trappet’s world is full of creatures. Some are friendly. Others are… working on it. Where you are and what time it is decide who turns up. The goblin, sadly, turns up everywhere.
At night, Trappet gets a bit dark.
Trappet runs on real time. When the sun goes down where you are, it goes down in there, and the same fields fill up with other things. Lights in the cemetery. People in the woods who shouldn’t be. Most nights you just walk past. Some nights something notices.
Some things only come out at 3 AM, in a forest.*
* What you’re doing in a forest at 3 AM is your business.
Modding
Modders, we got you covered!
Trappet ships with plenty of tiles to draw the real world. But you can make your own, and choose what happens the moment someone steps in.
With the Lua SDK you can code literally anything: new tiles, new NPCs, and the exact places they show up. How much water, how much forest, a cemetery or a cave nearby.
How modding works
01Draw a tile.
Pixel by pixel, in the colours you like. This one is a pier for a quiet river.

Custom NPCs?
Of course!
Trappet’s world is full of life, and you can add to it: any creature, any interaction, any behaviour. Here’s one pig and three ways to write it. Pick one, then go and bother it.

Featured this week
Grandpa’s Pier
by @lucia_px
A quiet pier on a forgotten river. Sit with the old man long enough and he’ll tell you where they bite.
Also includes:
- Animated water
- Grandpa (NPC)
- Dawn and dusk lines
The Workshop
“Meet me on the hill behind the church.”
We’re building a Workshop where anyone can share their mods. Install a friend’s, walk up the hill behind the church, and there it is: their tile, in the real world, waiting for you.
Community
Pull up a log.
Trappet is being built in the open, on Discord. Chat with the devs, tell us what you’d love to see in Trappet, and get the devlog and modding tools before anyone else. The best ideas might end up in the final device. Everyone you met on the way down is already there.
Being built right now
No big studio.
Just us and our pets.

By day we build hardware and software for tech companies. The rest of the time, we build Trappet. Here’s a year of it: the places that inspired it, the people (and animals) we met along the way, the prototypes that worked, the designs and mechanics we scrapped, the engineering, the marketing, the music and, of course, our pets. We won’t lie to you: they do all the work.
