Is this a replacement for Resolume?

Not for a professional VJ. Resolume mixes clips, maps projectors and takes MIDI, and Vortexia does none of those. It replaces the specific case of wanting live audio-reactive visuals without buying, installing or learning a suite, which covers most streamers and a lot of DJs.

What other free VJ software is there?

TouchDesigner is free for non-commercial use, capped at 1280×1280, and is a node-based environment you build visuals in. Hydra is free, open-source live coding in the browser: you write short code to make the picture. projectM is an open-source music visualizer compatible with MilkDrop presets. Each is a good tool; Vortexia is the one designed around a stream, with an OBS link, channel events and Stream Deck triggers.

What do I actually get for free?

Three of the eight engines at 720p and 30fps with a small watermark, Twitch integration, and no time limit or card. It is a tier rather than a trial. Plus at $4.99 a month removes the watermark and adds 1080p at 60fps, all eight engines, and automatic YouTube and Kick events.

Can I control it live during a set?

Yes. Changes you make in the dashboard, such as preset, colour, zoom or engine, reach your OBS source within a couple of seconds without touching OBS. Effects fire from the dashboard buttons, Shift+Alt+1 to 6, or trigger links on a Stream Deck key for drops and transitions.

How do I get my DJ software audio in?

In Chrome or Edge on Windows, set Listening to Music / system and share the screen your DJ software is on, with the audio box ticked. Elsewhere, route its output to a virtual cable, VB-Cable on Windows or BlackHole on a Mac, and choose that as the browser’s microphone, or use an audio interface or mixer with USB out, which already appears as an input.

Can I put it on a projector at a gig?

Yes. Open vortexia.live/ambient on a laptop connected to the projector and tap Start: no account, the screen stays awake, and it listens through the laptop’s microphone.

Does it need a good machine?

The 2D engines cost about a millisecond per frame at 1080p. The two 3D engines are much heavier, so they start at 720p and reach 1080p on the High setting. Performance Mode lowers the render resolution if the same machine is running a game or your DJ software.

What is Free VJ Software in Your Browser?

Vortexia is free VJ software that runs in your browser: live, audio-reactive visuals with no download, no licence key and no install. It generates the picture on your graphics card from the music itself, with eight fractal engines, a pulse on every kick, and bass, mids and treble each driving a different part of the motion. Be clear about where it fits. Suites such as Resolume mix video clips, map projectors and take MIDI; Vortexia does none of that. It suits a DJ streaming a set, a bedroom producer, or anyone who wants a moving backdrop in OBS or on a venue screen without building one. Among the other free options, TouchDesigner is free for non-commercial use up to 1280×1280 but is a node-based environment you build visuals in; Hydra is free, open-source live coding in the browser; and projectM is an open-source visualizer compatible with MilkDrop presets. Vortexia is the one built around streaming: one OBS link, Twitch events on the free plan and trigger links for a Stream Deck. The free plan runs at 720p with a small watermark and no time limit.
