Pricing

One runtime. Three license paths.

The engine remains source-available for personal study. The desktop app is a free download with a 10-day Baryon Pro trial; a Pro license is the paid path for performance use. Distribution, hosted services, OEM, and installation work sit on a commercial license.

Personal study and non-commercial engine use remain under the public source license.

The desktop app is free to download; a 10-day Baryon Pro trial unlocks Performer Mode, stage output, and OSC/MIDI control.

The Founder License is the early-supporter lane: a perpetual Baryon Pro desktop license, separate from the trial and subscription paths.

Distribution, hosted services, OEM embedding, and installation work require a commercial license.

The pricing model

Baryon has three clear use boundaries: public engine access for study, Baryon Pro for desktop performance use, and a commercial license for anything that ships, hosts, embeds, or deploys to a client. Keeping those boundaries explicit keeps the source license honest and the commercial path predictable.

Personal and non-commercial engine use

The engine is source-available for personal, educational, research, and other non-commercial use under PolyForm Strict. This path is for studying the runtime, modifying it privately, and contributing improvements back.

Desktop product path

The desktop app is free to download and explore in Listener Mode. Every install includes a 10-day Baryon Pro trial that unlocks Performer Mode, Syphon and Spout stage output, and OSC/MIDI control — started from inside the app, no account required. When the trial ends, a Baryon Pro license keeps those tools for live use.

The Founder License is the early-supporter lane, separate from the trial and subscription paths: a perpetual Baryon Pro desktop license plus founder perks, for people who want to back Baryon early and own their license outright. A perpetual license keeps Performer Mode on every build included in its update window, subject to periodic license validation. Annual update renewal adds another year of eligible feature releases; critical hotfixes remain eligible with the feature release they repair.

The newest Baryon build always remains available to download and run in Listener Mode. If a perpetual license does not include that build, Performer Mode stays locked and Baryon offers both update renewal and the newest eligible archived installer.

Commercial license path

A separate commercial license is required when Baryon becomes part of something you ship, sell, host, embed, or install for a client — distributed products, hosted services, OEM embedding, fixed installations, and similar deployments.

How to choose

  • Public source path — you are studying the runtime or experimenting privately.
  • Trial path — download the app and run the 10-day Baryon Pro trial to evaluate Performer Mode with your own rig.
  • Founder License path — you want to support Baryon early and own a perpetual Baryon Pro desktop license for your performance work.
  • Commercial license path — Baryon becomes part of a distributed, hosted, or deployed product.
