LAN Waifu
Ember Pro
Fireball
She charges a fireball in her hands and throws it. Her target runs about in a panic, in flames.
aimed · 5 s burn
A little friend for your editor, with superpowers.
She walks along your VS Code window, cheers when you save, naps when you don't, and carries messages to your teammates' screens.
For VS Code and Cursor, on Windows, macOS and Linux.
What she does
Free, for everyone. Set a room code to share her with your team; without one she's yours alone and nothing goes on the network.
Roams your whole window
She walks along the bottom of VS Code, over editors, sidebar and terminal. Drag her anywhere and she drops back down.
Reacts to your code
Cheers when you save, frets at errors, celebrates commits, sits out of the way while you type, naps after two idle minutes.
Visits teammates
Now and then she walks off the edge onto a teammate's screen. Theirs visit you the same way, then head home.
Can be thrown
Grab her and fling her off the edge: she flies onto your teammate's screen and crash-lands there.
Carries messages
Send a teammate a note or a sound. She walks it over in person and tells them, in her own words.
Has a menu
Right-click her for everything she can do, in her own colours, down to typing your message in a box over her head.
The cast
Pick one. Each has her own look, her own voice and her own signature power.
☾ Midnight
Calm, sleepy, quietly fond of you.
❄ Frost
Cool and aloof. Cares more than she shows.
♡ Sakura
Bubbly. Everyone's best friend on day one.
✧ Violet
Dreamy and mysterious. The stars told her.
✦ Ember
Fiery. Turns everything into a race.
✿ Honey
Sweet. Brings snacks, worries about you.
☘ Mint
A cheeky prankster with a giggle.
LAN Waifu Pro: the move list
Right-click your character or press Ctrl+Alt+P. Aimed powers fly to the character you pick, across to a teammate's screen if that's where she is.
Frost Pro
Freeze
An ice shard turns her target into a block of ice, which cracks and shatters as it wears off.
aimed · 5 s freeze
Sakura Pro
Heart beam
A heart charms its target into walking over to Sakura, hearts circling her head, even from another screen.
aimed · crosses screens
Honey Pro
Sweet heal
Honey and candy for a friend: she shakes off any ice, fire, charm or bugs, cheers in a column of golden sparkles, and keeps a golden shield for 2 minutes that every attack, and Midnight's lullaby, bounces off.
aimed · cures · 2 min shield
Midnight Pro
Moon glide
Midnight summons a crescent moon and rides it about the window, and every character in the room, on every screen, falls asleep for 8 seconds. Only Honey's shield keeps one awake.
everyone · 8 s of sleep
Mint Pro
Bug jar
Mint lets a jar of bugs loose on a teammate: her character runs about covered in bugs, and her code looks bugged for 10 seconds, with typos, squiggles and bugs crawling over it. Only looks: the file is never touched.
aimed · 10 s of bugs
Ember Pro
Fire dash
She blazes across the whole window on a trail of fire. Anyone in her way goes flying.
area · knocks back
Violet Pro
Shadow portal
She sinks into her portal and rises right next to any character you pick, on whichever screen she's on.
teleport · any screen
Everyone Pro
Teleport
Vanish in a puff of smoke and pop up somewhere else on your screen, or next to a teammate.
teleport · any screen
Everyone Pro
Fly
Up and away, superhero style: she soars back and forth over your code, then glides down to land.
8 s flight
Everyone Free
Dance
No license needed. Every character has her own dance, in her own style: Sakura's idol hearts, Violet's spell-casting twirl, Mint's peace signs.

Questions
Does she send my code anywhere?
No. She notices only that you saved, made an error or typed fast, never what your code says, and that stays on your machine. With a room code, she sends only what's needed to visit teammates and carry messages, encrypted with a key made from the room code; without one, nothing leaves your machine. More in the privacy policy.
How do teammates find each other?
Everyone sets the same room code. On the same network (an office LAN) characters find each other automatically; across networks, you can list each other's addresses or use a relay.
Which systems does she work on?
Windows and macOS, and Linux in an X11 session or on KDE Plasma, where she roams the whole window. On other Linux desktops she walks along your open editors instead, and the superpowers aren't available there.
Do my teammates need Pro to see my powers?
No. Anyone can be hit by a fireball or charmed by a heart. Pro is for casting them.
Is Pro a subscription?
No. $4.99 once, and it's yours for good on up to
3 machines. Moving to a new machine? Run

Can I get a refund?
