Your farmer
Heal, hurt, refill or drain energy, warp you home, invincible, frozen, faster or slower, a random hairstyle or upgrading and downgrading the tool you hold.
Your chat moves onto your farm: they give or take gold, change the weather and the time, fill the fields with slimes and bats and drain your energy.
Four stops, in under a second.
From TikTok, Twitch, Kick, YouTube or Starvios: a gift, a follow, likes or a chat command.
Receives the event, checks your active profile for the matching effect and sends it.
SMAPI is Stardew Valley's mod loader. The app installs it along with the OverInteractive mod, which runs every effect in your save.

The effect reaches your farmer instantly.
Everything happens from the game's status bar, at the bottom of the app.
It detects Stardew Valley in your Steam library. If it lives somewhere else, press «Set path» in the bar below and pick it.
Press «Install mod». The app downloads SMAPI, places it next to the game and puts the OverInteractive mod in the «Mods» folder. The game's executable is not touched.
The app starts Stardew Valley through SMAPI, which is what loads the mod. From Steam the game opens without mods.
SMAPI's black window opens next to the game: that's normal and you shouldn't close it.
With the game open, the bar below switches to «Connected». Effects apply as soon as you load a save.
In «Profiles» create an example one in a click or build your own: each gift, follow or chat command fires the effect you pick.
Each effect is assigned to a gift, a follow, likes or a chat command.
Heal, hurt, refill or drain energy, warp you home, invincible, frozen, faster or slower, a random hairstyle or upgrading and downgrading the tool you hold.
Give or take gold, gift you a specific item or max out the day's luck.
Rain, storm, snow, wind or clear skies, changing the time of day or dropping forage around you.
Slimes of every color, bats, crabs, ghosts, serpents, skeletons, golems… or wiping out every monster at once.
If you open it from Steam, Stardew Valley starts without SMAPI, the mod doesn't load and the bar stays at «Stopped». Use «Launch game».
Nothing applies on the title screen. With a menu open, during an event or a cutscene, the effect may wait until you get control back.
The OverInteractive mod lives in its own folder inside «Mods». Installing or removing it doesn't touch your other SMAPI mods.
Download OverInteractive for free: this same guide is waiting inside the app, in the game's «Start» tab.
