1UP Vision

Vision is a browser-based overlay editor for livestreamers on Twitch and YouTube. You design your stream layout once, add it to OBS as a browser source, and every change after that shows up on stream instantly, without reloading OBS.

Unlike most overlay tools, Vision is built for teams. Your mods can edit the same overlay with you in real time, like a shared document, so they can update scores, count in-game deaths, switch scenes or bring guests on air while you play. Roles and permissions decide who can change what (for example, mods can edit scores but not the layout), and every action is logged.

Features:

Overlay editor: a real-time canvas with layers, snap guides, multiple scenes and animated transitions, custom CSS, Google Fonts and custom fonts, videos and a live stream preview behind the overlay. Alerts: keyframe-animated alerts for follows, subs, bits and tips, with text-to-speech (about 50 voices in 14 languages), conditions per event and import from StreamElements. Guest calls: low-latency callers with camera or screen sharing, an audio mixer, N-1 routing and talkback, delivered straight into the overlay. Interactive events: quiz shows and tournaments where viewers take part in real time. Sponsor rotations: logo rotations by game, title or campaign, with impressions per logo you can export as CSV. Chatbot: commands, timers and moderation for Twitch and Kick. Chat commands can change counters, scores and countdowns in the overlay. Shared overlays: run the same overlay in several OBS instances when you stream together. Extensions: third-party developers can build their own components with the Vision SDK.

There is a free plan with no credit card required. Paid plans add more overlays, alerts, guest calls and custom roles.
