Comparisons
Compare DecisionManager
Every comparison here is written the same way: a capability-by-capability table, the measurements behind the rows that carry the most weight, and a stated list of what the other engine does better. Nothing is claimed that the tables do not show.
Live differentiators
What you can measure today
Step budget, wasm/edge packaging, decision warehouse, and a free trial that is not empty — shipped capabilities, not a roadmap slide.
Deterministic step budget
Same input reaches the same verdict under load and on regulatory replay — bounded by steps, not a wall-clock timer.
LiveWasm & edge bundles
Verified wasm32 engine and hash-verified edge bundles — Lambda, Workers, Cloud Run, or no-database edge under your account.
LiveDecision warehouse
Post-hoc explanation, execution history, and KPI streams so operators prove what ran after the fact.
LiveFree trial, seeded
Signup creates a project, decision service, ruleset, published version and active dev deployment in one transaction — no empty shell.

Honest comparisons only
Every head-to-head page states what the other engine still does better. We will not invent ODM or Drools weaknesses to win a bake-off on paper.
DecisionManager vs IBM ODM
Runtime architecture, decision latency, deployment model, developer experience, licensing and governance, side by side — plus the commercial comparison and the places IBM ODM is genuinely ahead.
DecisionManager vs Drools / Red Hat KIE
Architectural contrast with Drools and KIE Server: measured Rust runtime figures, edge deployment and governance — plus where Drools still leads on stateful inference and the Java ecosystem.
DecisionManager vs Pega BRE
Deployment model, AI authoring, edge execution, and governance compared against Pega Business Rules Engine and Next-Best-Action. Includes what Pega leads on: case management, SI ecosystem, and formal certifications.
DecisionManager vs Camunda DMN
BRMS focus vs BPMN process orchestration. Deterministic step budget, WASM edge, and governance lifecycle compared against Camunda's DMN and FEEL engine. Includes where Camunda leads: open source, DMN standard, BPMN orchestration.
After the comparison
The next question is usually what a move would actually involve, and what you would be moving onto.
