Fixie uses a high-performance tree-graph architecture that represents messages as internal maps and lists, outperforming legacy engines. This approach eliminates the "conversion tax" of traditional canonical objects; internal data is simply added as subtrees. Because the structure is natively hierarchical, it converts to JSON instantly whenever visibility or downstream integration is required—all without sacrificing the engine's low-latency hot path.
Configuration, status, and message inspection are available in a clean web UI, supported by command-line controls for seamless runtime management.
Measure and analyze the performance of your FIX infrastructure with built-in tools designed to identify latency bottlenecks under load.
Accelerate your time-to-market by ensuring your infrastructure meets the specific requirements of financial venues with our automated certification tools.
Download Fixie, unzip it, and run one command. The local console provides the runtime guide, editable configuration, status, and message browser.
