DMN-first decision platform

Rule Management for Modern Teams

Move business logic out of hardcoded services and into a governed DMN workflow. Themis helps teams collaborate on rules, validate changes, and deploy decision logic with speed.

  • DMN-first
  • API-ready
  • Team-safe governance

Runtime architecture

Drools-powered decision execution with no server-restart deployment

Themis runs on Drools, a battle-tested rule engine, and supports deployment of new rule pushes without restarting servers.

Note: Initial request latency may briefly increase right after new rules are deployed while warm-up completes.

Features

Core capabilities built for decision logic

From source management to runtime execution, Themis gives teams a full operating layer for business rules.

Git-Backed Rule Sources
Connect repositories and branches to keep every rule change versioned, reviewable, and recoverable.
Deployment and Execution
Ship decision logic quickly and execute it via API using structured inputs for deterministic outcomes.
Validation and Simulation
Test scenarios before release to catch regressions and improve confidence in business-critical decisions.
Deep Rule Search
Find decision models, rules, and dependencies across sources without manual digging.

Team operations

Governance that feels fast, not heavy

Give every team a safe path to release rule changes with clear ownership, approvals, and traceable outcomes.

  • Keep product, engineering, and operations aligned on decision outcomes.
  • Reduce risk with explicit ownership and controlled release workflows.
  • Maintain traceability from proposal to production execution.

Workspace Isolation

Separate decision assets by team, organization, or environment while preserving a consistent operating model.

Role-Based Access Control

Gate sensitive actions so only authorized users can change models, deploy releases, or manage members.

Audit-Ready History

Track who changed what and when to support governance, incident response, and compliance workflows.
