Styra Load Introduction

Styra Load is an enterprise-grade drop-in replacement for the Open Policy Agent (OPA) that offers:

  • Datasource integrations: Connect quickly to your Kafka, LDAP, S3 without needing to write or manage your own plugins.
  • Secrets manager integration: Connect to HashiCorp Vault to securely use http.send.
  • Logging integrations: Send your authorization decision logs to Splunk or Kafka.
  • Live impact analysis: Check to see if your new policies impact production before they are merged.
  • Lower costs: Use cheaper cloud infrastructure because Styra Load uses 10x less memory and 40% less CPU than OPA.
