The best moments of a stream deserve more than a chat spam — they deserve the screen itself reacting. Kloot’s effects library puts confetti, emoji rain, fireworks, and screen shake on deck keys you fire by hand, so the eruption lands the exact second your reaction does. Every effect plays over the whole scene for a few seconds and cleans itself up. Here is how to build your set — including a custom emoji button — and fire it from your phone.

It lands here — press a key, it's real
What you’ll build
A fire set of hype effects — presets plus your own custom emoji buttons — pinned to deck keys you smash from your browser or phone, each erupting over the full scene and clearing itself.
Paste your single Kloot overlay URL into one Browser source in OBS and size it to your canvas. That one source powers every effect and every other Kloot tool — you never add another browser source.
Already have Kloot in OBS from another tool? Skip this — effects ride the source you already added.
Open the Emojis tool and switch to the Build lane. Add the emojis you want on hand from the built-in library — a 🔥 for clutch plays, a 💀 for terrible puns, whatever fits your stream. Everything you add lands in your fire set, ready to fire and pin from the Fire lane.
On Creator and Pro you can also upload your own images and GIFs (PNG, GIF, WebP, SVG — up to 2MB) and fire those like any emoji. The Free plan uses the built-in library.
The default style governs your set: Single pops one big emoji (pop, slam, bounce, spin, or pulse), Burst sends a crowd of them in the direction you pick — rain down, rise up, explode from center, or sweep across. A 🔥 that rises reads completely differently from a 🔥 that rains.
Dial in burst count (1–50), duration (1–30 seconds), and scale (1–10). A quick 8-emoji burst is a reaction; a 40-emoji, 10-second downpour is an event. Tap any tile body in the Fire lane to preview safely inside the panel — only the red Fire pill goes live.
Each key you pin keeps its own copy of these settings, so your everyday reaction and your milestone eruption can be the same emoji at very different power.
Pin your custom emoji buttons and favorite presets (confetti, fireworks, heart rain, shockwave) to deck keys. The deck runs in any browser and installs as an app on your phone — so the phone next to your keyboard becomes the hype button. One tap, instant eruption, auto-cleanup.
Keep pressing during a big moment — effects stack (up to five at once), and a short per-key cooldown keeps it from turning into soup.
Setup is three minutes — this is the loop you’ll run a hundred times a stream: the moment, the key, the eruption, the cleanup.
A clutch play lands, a big donation drops, a raid rolls in, chat goes vertical. This is exactly the moment automated alerts miss — because the reaction that matters is yours, not a bot’s.
One tap on a deck key — in your browser, or on the phone next to your keyboard — and the effect fires instantly. No menu, no arming step, no delay between your reaction and the screen’s.
Confetti, emoji rain, fireworks — each effect plays over the whole scene for a few seconds and then removes itself. There is nothing to dismiss, hide, or reset; the scene is clean before you’ve stopped grinning.
Big moment? Fire again before the last one ends — effects layer on top of each other (up to five at once, the newest always lands). Confetti into fireworks into a 🔥 rise is a legitimate strategy.
A hype effect is your reaction, made screen-sized. The moments where one key press earns its place:
When: The 1v4 lands, the boss finally dies, the impossible jump sticks.
Why it works: The screen erupting the same second you do makes the moment feel bigger — and it clips beautifully. A manual key means it fires on YOUR reaction, never mid-whiff.
When: Sub goals, follower milestones, channel birthdays, someone’s first ever donation.
Why it works: Confetti and fireworks turn a number ticking over into an on-screen event. Fire it while you say thank you and the celebration lands as one beat, not two.
When: You keep a signature emoji on a key — a 💀 rain for terrible puns, a 🫡 for fallen teammates.
Why it works: Fired at the same kind of moment every stream, one emoji becomes an inside joke your regulars wait for — the cheapest community ritual you can build.
When: Just Chatting, cooking, music, IRL — formats where there are no game events to hook anyway.
Why it works: Event-driven alert tools have nothing to listen to here. A manual key doesn’t care what you’re streaming: if it felt like a moment, it gets an eruption.
Every preview below is the real effect engine firing on a loop — the same eruption your viewers see, not a mockup.
The universal celebration — reads instantly at any size.
Sub goal hits mid-game: one tap and confetti pours over the scene while you say thanks. Three seconds later it’s gone and nobody touched OBS.
One key, fires instantlyA downpour of any emoji you pick — your signature move.
Keep a 🎉 rain on one key and a 💀 rain on another. Same effect, different emoji, completely different meaning — chat learns both within a week.
Pick the emoji per keyThe same rain engine, reversed — embers floating up the screen.
Someone in chat says the play was “kinda fire”? Prove it. Rise ↑ direction turns any emoji into a slow-burn flex that reads great over dark scenes.
Direction is per key: rain, rise, explode, sweepThe big-occasion effect — save it and it stays special.
End-of-stream win, tournament qualification, a milestone months in the making. Fireworks are the one you don’t fire every day — which is exactly why they land.
Stack it over confetti for the full finaleNowhere to place, nothing to anchor: effects play over the whole scene, above everything, and clear themselves when they’re done.
No — by design. Kloot is manual-fire: you press the key, so the eruption lands on YOUR reaction, in the same beat as your voice. An auto-fired effect during a whiffed play is exactly the awkwardness this avoids — and it means effects work on any platform, with no event wiring.
Any emoji from the built-in library works on every plan, including Free. Uploading your own images and GIFs (PNG, JPEG, WebP, SVG, or GIF up to 2MB) — your sub emote, your mascot — is a paid feature on Creator and Pro.
None — the effects library is free forever, with a small watermark until you upgrade. It is the easiest way to start with Kloot: build a fire set tonight, upgrade later only if you want uploads or the paid tools.
Yes — fire again before the last one ends and they layer, up to five at once (the newest always lands; the oldest clears first). Each key has a short 1.2-second cooldown so a mash stays hype instead of turning into noise.
They are tuned to be light: each effect runs for a few seconds through the same single browser source as every other Kloot tool, then removes itself completely. Nothing keeps animating in the background.
No — every effect cleans itself up. It plays over the whole scene for its duration and disappears. There is nothing to dismiss, hide, or reset between fires.
Confetti, emoji rain, fireworks, screen shake — build your fire set in three minutes and it’s on a key before your next stream. Free forever, with a small watermark until you upgrade.
