Streaming Companion
Your entire broadcast control room, owned outright.
StreamSync collapses your chat bot, alert box, moderation panel, and automation tool into one desktop app that talks directly to Twitch — and, in Pro, YouTube, Kick, and Facebook Live at the same time. Stop paying five different services to run one stream.

Local-first
Your data never leaves your machine. OAuth tokens live in your OS's secure credential store — StreamSync's own servers see nothing.
No subscription
Buy once, own it. The Demo/Pro split is a one-time purchase, not a monthly plan.
Honest scoping
We tell you what's not supported yet instead of shipping a broken button — like Kick's live-event coverage, which is clearly scoped.
Headline Features
Everything you need to run the show
Multi-platform chat bot
One bot, one command set — works across Twitch (all editions), plus YouTube and Kick chat relay in Pro. Commands, timers, counters, and quotes share a single config.
Visual overlay builder
Drag-and-drop alerts, chat boxes, and stream-info widgets onto a 1920×1080 canvas — no HTML/CSS required. Generates OBS-ready browser-source URLs instantly.
Triggers & Actions automation
65+ action types spanning moderation, OBS control, channel points, polls, file I/O, and webhooks — with logic gates, branching, and queues so alerts never overlap.
Real on-screen alerts
Animated follow/sub/raid/cheer/redeem alerts with a shared batching engine, so simultaneous events display together instead of stuttering one after another.
Points, loyalty & mini-games
Automatic viewer point accrual with a sub multiplier, plus !slots, !roulette, and !gamble commands built in.
Giveaway system
Keyword-entry giveaways with duration timers and winner redraw — and automatic resume if the app restarts mid-giveaway.
Built for power users
Tier 2-
OBS Studio remote control
Scene switching, source visibility, filters, audio muting/volume, text-source rewriting, media triggers, and recording/streaming start-stop — all triggerable from stream events.
-
Deep Twitch coverage
Polls, predictions, channel-point reward management, raids, shoutouts, warnings, VIP/mod management, chat mode toggles, announcements, and stream markers.
-
Persistent global variables
A key-value store usable in chat responses, overlay JS, and triggers — with a local REST endpoint for building your own integrations.
-
Quote database
CSV/JSON import with searchable in-app management.
-
Chat quality-of-life
BTTV/7TV/FFZ emote support, Twitch badge rendering, per-user nicknames, and a pop-out chat window.
What Pro unlocks
One-time upgradeYouTube
Live chat polling with Super Chat, Super Sticker, and membership normalization, plus ban/timeout/mod tools and title updates.
Kick
Chat sending, channel status, and moderation via REST. Kick has no live event feed yet — we scope that clearly rather than overpromise.
Facebook Live
Page live-video comment polling and sending as a full chat surface.
StreamHub bridge
Trigger a post directly to Discord, Facebook, Instagram, YouTube, X, or Threads from a Twitch event — without StreamSync ever holding those platforms' credentials.
Better Together
Connect StreamHub once, and let StreamSync post your raid alerts, follow milestones, or stream-start announcements automatically — no copy-pasting, no extra login. The two apps talk over a password-protected connection that never leaves your own computer, and StreamSync never sees your StreamHub platform credentials — only an opaque destination name.
