Benchmark results

These are measured results produced by the Neuron-JS benchmark harness (yarn benchmark). They compare @sebasoft/neuron-js against json-rules-engine, json-logic-js, a hand-coded TypeScript baseline, and rule-engine-js across the pricing, eligibility, and workflow-routing scenarios. See the methodology for how each metric is collected.

Numbers reflect a single machine, Node version, and commit; reproduce locally before citing. No value on this page is hand-entered — charts and the table below are generated from the same source file.

Throughput comparison

metric: throughput_decisions_per_second · decisions / second · higher is better

Cold-start comparison

metric: cold_start_ms · milliseconds · lower is better

Bundle-size comparison

metric: bundle_size_minified_bytes · minified bytes (esbuild, node platform) · lower is better

Validation overhead

metric: validation_overhead_ms · milliseconds per decision · lower is better

Neuron-JS differentiator: competitors provide no schema-validation step (0).

Explanation overhead

metric: explanation_overhead_ms · milliseconds per decision · lower is better

Neuron-JS differentiator: competitors provide no explanation trace (0).

Full results (medium · 10,000 decisions)

Throughput is decisions/second (higher is better); all latency, cold-start, and overhead columns are milliseconds (lower is better); bundle size is minified bytes.

Validation and explanation overhead are Neuron-JS capabilities (validateScript, explainExecution); the other engines provide no equivalent step, so their measured delta is 0.
