What it does

Built for streamers who want control

Game-aware profiles

SparkStream sees which app is in focus and switches your active rewards to match. A cloud bot cannot: it runs on a server that never sees your screen.

Stream event triggers

Follows, subs, gift subs, bits, raids, hype trains. Every event triggers the same action system: hotkeys, sounds, scripts, HTTP requests, TTS, programs.

Approval queue

Flag any reward to require manual approval before it fires. Approve runs the actions. Decline skips them and refunds the viewer their points automatically.

On-stream overlays

Drop-in OBS overlays for goals, alerts, chat, a pricing ticker and more. The Layout Editor combines them into one browser source, and a Smart Zone auto-arranges whichever are live right now.

Mini-games and auctions

Turn channel points into moments: Spin the Wheel, dice rolls, live auctions that refund outbid viewers instantly, and an end-of-stream credits roll.

Smart Queue

Redeems become quest cards on a clean overlay instead of alerts that break your focus. Clear them when it suits you; rejected or missed cards refund everyone automatically.

Spotify integration

A now-playing overlay, playback hotkeys, and channel-point song requests that add tracks straight to your queue. Runs on your own Spotify app, tokens stay on your PC.

Dynamic pricing

Let reward prices rise with demand and cool down over time, with an optional on-stream ticker. Free covers two rewards; Pro unlocks them all.

E2EE direct messages

Encrypted end-to-end. Your private key never leaves your device. SparkStream cannot read your messages: not in transit, not at rest, not ever.

Team management

Delegate to mods with scoped roles: Mod, Senior Mod, Lead Mod. Scripts and API keys stay Owner-only. Every mod action is logged to a private audit trail.

Achievements and leaderboards

Unlock badges and secret themes as you use SparkStream, some granting Pro credits. Ranked overlays for gifted subs, bits, redemptions and more, free with no gating.

How it works

Rewards go in. Actions come out.

Point any channel point reward or stream event at what happens on your machine: a scene switch, a sound, a script, a hotkey, an overlay. It runs where your stream does, so there is no cloud round-trip and nothing to leak.

Privacy

Minimal data. By design.

By default we hold little more than your Twitch username, your licence status and the devices signed in to your account, and your chat and stream events stay on your machine. Anything more on our server exists only because you switched on a feature that needs it. Three opt-in Pro features are the exception: analytics and the mobile queue touch redemption data, and the hosted chat bot reads your chat to spot commands without storing it. Analytics hashes viewer ids so individuals are never named. Messages are end-to-end encrypted: unreadable to us by architecture, not policy.

Free is not a trial

Rewards

Bring a friend, get thanked for staying

Every SparkStream account gets a personal referral code and a running loyalty bonus. No sign-up, no catch: both are automatic.

+7 credits
Refer a friend

Your referral code is just your Twitch username. Share it, and a friend who enters it gets a bonus month of Pro on us. The moment they subscribe, you get 7 Pro credits (about a week) added to your own account.

+5 / month
Loyalty bonus

Every month you stay subscribed to Pro, you earn 5 bonus credits on top of your renewal, a thank you for sticking around. That adds up: about six months in, you have banked roughly a free month. Credits never expire while you are subscribed, and if a payment is ever late, banked credits quietly keep Pro running instead of cutting you off.
