The FIX fabric that works for every counterparty.
In principle FIX is the common language of the buy and sell side. In practice every counterparty speaks a slightly different version — separate channels per asset class, different dialects per order type, networks with their own routing logic. Quazar is the AI-native fabric that absorbs that complexity.

Twenty years of FIX, rebuilt for the AI era.
Quod Financial has built and run three generations of FIX connectivity and routing software — for our own business, at production scale.
Along the way we have navigated thousands of inbound and outbound gateways across disparate networks and routes. The problems are always the same: varying versions, dialects and rules; custom mapping and routing rules for each order flow; and labour-intensive certification. Networks are frequently proprietary with little cloud capability, and specifications are often out of date — errors that only surface during certification.
The result is familiar. Engineering teams end up as glorified IT support, spending weeks debugging tags instead of building trading infrastructure.
Quazar applies the 10x rule to FIX. A deterministic, low-cost, low-compute layer that lets AI manage the complexity underneath — built on a cloud-native architecture designed to absorb scale at a fraction of the traditional cost. Whether you run a handful of connections or automate thousands of routes, you stop fighting the infrastructure.
A new paradigm.
Quazar sits between two FIX-enabled systems. Incoming messages are matched against your mapping rules, rewritten into the format the receiving system expects, and forwarded on.
Your OMS, or any FIX-capable application, connects to Quazar. No front-end changes required.
Quazar applies your rule set — translating between FIX versions, correcting tags, mapping fields. Rules run from simple remappings to conditional transformations by asset class.
The normalised message is translated into the receiving system's dialect and forwarded. Order lifecycle, parent/child relationships, algo parameters and execution IDs are preserved end to end.
Session health, latency metrics and audit logs surface in a single control plane. Routing rules are managed through the REST API.
FIX-to-FIX routing with merge and split.
- Pass-through, fan-out, funnel-in, many-to-many
- Market data fan-out and drop-copy
- AI and visual rule builder
- REST-managed — no restart to change a route
- Conditional and failover routing — coming
Multi-session FIX engine with no hard session limit by design.
- SSL-encrypted sessions
- Sequence number and session settings via GUI
- Shared SenderCompID and TargetCompID, split by SubID
- Data dictionary changes without a session restart
- Config rollback to last known-good state

- Rollback to last known-good configuration
- Automated hub failover — on the roadmap
Dashboards with admin and runtime route tracing.
- Session, message flow and system health
- Latency tracking and real-time alerting
- Audit trail of who did what, and when
- Message-level troubleshooting — view an incoming message, the rules and FIX manipulations applied, and the resulting outbound message
- Full order grid — coming 2026
- Web UI — coming 2027
Managed, sorted.
Running hundreds to thousands of FIX connections is labour-intensive and, more often than not, an impediment to the business.
The cost of onboarding, certification and connectivity can be high enough that establishing a new client route becomes prohibitively expensive and slow. A route that should take days takes months.
We have streamlined and automated onboarding and certification using AI-driven auto-certification and testing. We use the cloud not only for compute, but to give you access to your own models and the wider cloud network. What traditionally takes weeks of manual FIX certification compresses to hours.
Onboarding
Counterparty onboarding and certification run as a managed service, from spec analysis to production cutover.
Operations
Session management, availability monitoring, incident response and counterparty connectivity, against defined service levels.
Maintenance
Upgrades, fixes and template updates handled for you, on-premise or cloud-hosted.
Cost matters.
Connectivity should not cost hundreds of dollars per connection per month. So for the buy side, it doesn't cost anything at all.
Download it, run it, plug in your own models or build your own MCP integrations. The full platform — routing, transformation, session management, monitoring and templates.
Managed in the cloud, with cloud-based routing across parts of your network. AI gives you deeper insight and greater control while cutting operational cost through automation.
Free buy-side access means firms on both sides of a flow can connect Quazar to Quazar directly, removing fixed-network fees entirely.
We do not charge for FIX-to-FIX connections.
We considered making Quazar open source. We decided against it, to protect the proprietary know-how we have spent twenty years building from being absorbed wholesale. Instead we made simplicity the strongest feature.
Individual connection plugins are a different matter. Where a plugin serves the wider market rather than the core engine, we intend to publish it openly.
Questions, answered.
What is Quazar?
An AI-native FIX Fabric: a high-performance platform for routing, transforming and managing FIX connectivity. It replaces fragile point-to-point infrastructure and expensive fixed networks with a single intelligent fabric you configure in minutes, not months.
Who is Quazar for?
Both sides of the flow. Buy-side firms connect directly to their brokers without paying per-connection network fees. Sell-side firms aggregate, normalise and manage hundreds of inbound client sessions through one platform.
Who builds and supports Quazar?
Quazar is built, supported and operated by Quod Financial — an owner-managed trading technology company with over two decades of FIX connectivity and trading systems experience. It is written in C++ for performance and reliability.
Is Quazar open source?
No. Quazar is proprietary software built and maintained by Quod Financial. It is free for buy-side firms for up to 10 inbound connections, with a growing library of pre-built transformation templates included.
