Operion
Event-driven workflows for every company on your platform, in one binary on PostgreSQL.
Catalog events
Register your Kafka events once and let each tenant build workflows on them, from webhooks and schedules too.
Your own nodes
Add node types as HTTP services in any language, with signed calls and answers that can come days later.
One binary, one database
Run a single container next to PostgreSQL, with waits and retries that survive restarts.
