A desktop app for Twitch streamers. From a single window it runs alert overlays, a full multi-channel chat client, a native chatbot, subathons, moderation tools, channel points, polls and predictions, OBS control, closed captions, and a clip manager. It runs entirely on your machine with a local server and embedded database, and installs in under 100 MB.
LuckyBot connects to Twitch directly with your login. No Streamer.bot required, though connecting one adds more sources. LuckyBot Cloud can relay Ko-fi, Streamlabs, StreamElements, Fourthwall, and custom WebSocket feeds, and includes a mobile companion for watching chat and events from your phone.
- Launch the app. The local server and database start automatically.
- Log in with Twitch. Events, chat, and channel actions work natively from there.
- Create an overlay using the drag-and-drop editor, the HTML/CSS/JS code sandbox, a widget, a reactive character, or a ready-made starter.
- Copy the overlay URL and paste it into OBS as a Browser Source.
- When an event comes in, the matching alert plays.
Optional: connect Streamer.bot over a local WebSocket, or add a LuckyBot Cloud token in Settings. When multiple sources deliver the same event, LuckyBot fires exactly one alert, preferring Twitch's own feed first, then Streamer.bot, then Cloud.
Overlays
- Drag-and-drop visual editor with layers, shapes, groups, motion paths, attachments, animations, keyframe timelines, and a properties panel
- Reactive overlays: a character with a looping idle animation and a reaction per event
- Full HTML/CSS/JS code sandbox with live preview, configurable fields, a console, and one-click template updates
- Ready-made templates: stream alerts, goal widgets, Spotify now playing, Twitch polls and predictions, subathon timer and goals, closed captions, weather, sound alerts, and more

- Weighted chance, variants with conditional logic, priority or random selection
- Per-alert duration, queue behavior, chaining, and optional text-to-speech
- Show and hide animations per layer, plus a keyframe animator for full timelines

- Counters can be dropped onto an overlay in one click and update live as commands run
