OpenResty Private Libraries
Enterprise-Grade Private Modules for Mission-Critical Applications

You've tuned everything you can reach. The bottleneck is in the code you don't control.
Community-driven fixes follow their own pace, leaving production incidents waiting while known CVEs linger on critical paths.
The biggest hidden cost of introducing new modules is the intrusion into existing systems and the overhead of transformation workloads.
Beyond our existing catalog, we specialize in building bespoke modules. From custom protocol support to specialized data processing engines, our team of core contributors turns your technical requirements into production-ready reality.
Open-source libraries are often designed for general-purpose use cases and can fall short under extreme loads. Performance bottlenecks are rarely isolated. Our proprietary modules address multiple critical layers across the entire request path. This includes everything from the LuaJIT runtime and JSON serialization to client implementations for mainstream protocols and databases like HTTP, Kafka, Redis, MySQL, and Memcached, as well as traffic limiting, dynamic metric collection, and I/O modules. Each module is meticulously optimized for real-world production workloads, with fine-tuning applied at every layer—from JIT compilation paths and memory allocation strategies to the Nginx event loop. This approach significantly reduces unnecessary context switching and GC pressure, resulting in processing speeds up to 10 times faster than open-source alternatives.
The open-source community operates on its own timeline. Your production incidents do not. When a known CVE or stability bug affects a critical component, waiting for an upstream merge can mean weeks or even months of unacceptable risk exposure. We deliver validated patches directly within our proprietary modules. Each patch includes comprehensive regression test coverage and detailed change logs, ensuring full auditability and traceability. This eliminates reliance on community release schedules and the need to maintain costly, unpredictable custom forks during critical moments.
The greatest hidden cost of introducing new modules is the potential disruption to existing systems. Our proprietary modules adhere to interface designs consistent with their open-source counterparts and are fully compatible with existing OpenResty/Nginx configuration syntax. Integration can typically be completed in a matter of hours. With a clear upgrade path and guaranteed rollback capabilities, technical decisions can truly be made independent of scheduling pressures, rather than being bogged down by extensive re-engineering estimates for every evaluation.
Each private module comes with OpenResty XRay authorization by default, providing dynamic tracing capabilities covering the Lua layer, C extension layer, and system call layer. Deploy and it's visible, exceptions appear and can be investigated, locate bottlenecks without modifying a single line of business code—OpenResty XRay is the foundational assurance for private module observability and our commitment to the long-term maintainability of each module.
