Comparisons anchored on Kestra, the Apache-2.0 event-driven orchestrator with declarative YAML flows and a paid Enterprise Edition, against other self-hosted workflow platforms.
Declarative YAML flows with a plugin catalog against code-first scripts, flows and internal apps. Compares Kestra and Windmill on authoring model and who can maintain workflows, supported languages, infrastructure (Kestra's single-server default and Enterprise HA backends against Windmill's PostgreSQL job queue), licensing, and the SSO, audit and secrets features each reserves for its paid edition.
What the Apache-2.0 Kestra edition does in production and what needs Enterprise: SSO, SCIM and RBAC, external secrets managers, audit logs, multi-tenancy, worker isolation and the high availability architecture with Kafka and Elasticsearch.
