JamKazam vs Jamulus

JamKazam lets musicians play live and in sync with others over the Internet from home. The service offers online sessions, open jams, scheduling, and searches for musicians by interests, instruments, proficiency, and connection latency. It also provides JamTracks: multitrack recordings whose parts can be muted or soloed for practice and playing along. Recording sessions and broadcasting performances through YouTube, Facebook, and Twitch depend on plan. New users receive 30 days of Gold features before their selected plan takes effect. Joining online sessions requires the JamKazam app, which the maker identifies as compatible with Windows 10 and 11 and macOS 10.15 or later. The app guides users through setting up audio equipment; setup instructions recommend an Ethernet connection to the router. Plans are Free at free, Silver at $4.99 a month, Gold at $9.99 a month, and Platinum at $19.99 a month. The Free plan limits sessions to one hour, four hours monthly, and four players, and excludes recording, broadcasting, and video.

Jamulus is free, open-source software for playing, rehearsing, or jamming remotely in real time over a broadband connection. It is described for choirs, bands, folk and classical musicians, music lessons, schools, and universities. In its client mixer, users can set the level they hear from each connected musician and use mute, solo, pan, and grouping controls. People connected to the same server can exchange text messages visible to everyone there. A connected MIDI controller can operate mixer volume, pan, mute, and solo controls, with availability depending on platform and version. Users may run their own server, but this is optional because clients can connect to listed or unlisted servers. Network conditions affect server quality; the manual says fewer than five players is usually fine on a slower home connection. Communications are sent without encryption, and normal use shares a user's Jamulus name, city, country, instrument, and skill level with connected servers, peers, and protocol-using third parties. When recording is enabled, unmodified servers show a notice, and the server operator controls recordings.
