No. Castio works alongside OBS: you set it up once as your stream destination and OBS stays the same tool you always use.
No. Castio is a web app: you open it in your browser and all you need is OBS. There's no desktop app to download.
No. You upload a single signal to Castio and we replicate it to each platform from our server. Your upload bandwidth is the same as with a single platform.
Today, Twitch and YouTube, with a direct connection. Kick and TikTok are coming soon.
There is no free plan. There are two plans: Standard (3 destinations, up to 720p at 60 fps) and Pro (5 destinations, up to 1080p at 60 fps). If you pay with Mercado Pago (Uruguay and Argentina), you get a 7-day free trial. If you join the beta, you get a founders promo.
Not yet. The 9:16 vertical format for TikTok and Shorts is in development and coming soon.
Since the signal goes through Castio before reaching each platform, it can add a small delay. We haven't published an official measurement yet: when we have one, we'll share it here.
Your keys are stored encrypted, and Twitch and YouTube connect through OAuth, with no keys involved. The signal you send to Castio can be encrypted; the output to each platform depends on what it supports, and in Twitch's case it is not encrypted. We never share your keys with third parties.
Yes, no lock-in. You cancel from your account and keep your plan until the end of the period you've already paid for.
Beta news, support and roadmap straight from the team. Tell us what feature you need and share your setup with other streamers.
We build Castio with a small team. Your support on Patreon helps us keep improving it and get to what's next faster.
