- Reading and writing .px files — The praxis language specification is MIT licensed. Anyone can author .px constraint files, decision ledgers, and procedures.
- Personal / non-commercial use — All Plures tooling (PluresDB, pares-radix, pares-agens) may be used for personal, non-commercial purposes under the Business Source License 1.1.
Using the following in a commercial or production capacity requires a commercial license from Plures:
- PluresDB — Reactive graph database and state engine
- pares-radix — Agent runtime with praxis evaluation
- pares-agens — Multi-agent orchestration framework
- Write your .px constraints and dev-guide content (MIT — yours to own)
- Evaluate them locally during development (BSL personal use — free)
- Run them in CI/CD pipelines or production systems → contact us for licensing
All BSL-licensed works convert to Apache License 2.0 on March 28, 2030. Before that date, commercial use requires an agreement.
