Tools for live performance shouldn't hold you hostage.
Ghost Arcade is built by performers, for performers. We don't want to be the company that calls home from a venue projector to re-validate your license five minutes before doors open.
The full source is on GitHub under AGPL-3.0. Use it, fork it, modify it, ship it. The only ask: contribute fixes back when you can, and credit the project where it's reasonable.
Common questions
Is it really free?
Yes. The full app, every effect, every output mode, no signup, no watermark, no expiry. Forever.
What's the catch?
AGPL-3.0 — if you fork it and host a modified version as a network service, you have to publish your changes back. Output you create with it (videos, livestreams, recordings) is yours, not ours.
Can I use it commercially?
Yes — for paid gigs, installations, broadcasts, anything. AGPL only kicks in if you redistribute the software itself or run a modified version as a service.
What about offline use?
It works fully offline forever. No license server, no activation, no callbacks. Install once, use anywhere.
Is there a paid version?
Not at the moment. We may build a separate commercial product (e.g. for houses of worship with on-site support) but the open-source app stays free and full-featured.
How do I support the project?
Star the repo, file good bug reports, contribute fixes, share your work, tell people about it. That all helps.
