About Baldur
Baldur is an in-application Python reliability framework that equips critical execution paths with retries, circuit breakers, and self-replaying dead-letter queues without requiring an external sidecar or service mesh. Installed as a pip package, it allows developers to compose resilience behaviors using function decorators, monitor events via an integrated web console and healing ledger, and optionally share state across processes using Redis. While the core framework is open source under the Apache 2.0 license, a paid PRO edition is available for production workloads.
