AI FIX Parser – a blazing-fast desktop app for parsing and analyzing FIX protocol messages. No cloud. No data ever leaves your machine. Future: AI-powered FIX engine generation.
Free to use. No sign-up required.
Built for traders, developers, and support engineers who work with FIX protocol daily. Fully offline — your data stays on your machine.

See every message in chronological order with sender, target, message type badges, order details, and one-click selection.
Click any message to see all tag/value pairs with human-readable descriptions, color-coded by category. Skip common fields with a checkbox.
Switch to the Raw Text tab for a clean, copyable text representation of any parsed message — perfect for tickets and documentation.
150+ tag descriptions and value lookups for MsgType, OrdStatus, Side, ExecType, TimeInForce, and more — no external reference needed.
Your data never leaves your machine. No network calls, no telemetry, no cloud — everything is parsed and rendered locally. Safe for sensitive production logs.
