Varnish (Wodby)
Boost your web performance with a powerful open-source HTTP cache. Gain deep insights and modern observability with real-time OpenTelemetry integration.
The Vinyl Cache Project is the open-source software formerly known as Varnish HTTP Cache. It is a high-performance web accelerator designed to significantly speed up content delivery and reduce backend server load. For nearly two decades, this project has provided a robust solution for caching HTTP traffic.
A key enhancement is the introduction of VCOT, a utility that brings modern observability to your cache environment. VCOT integrates seamlessly with OpenTelemetry by parsing Varnish Shared Logs (VSL) in real-time. This allows you to export detailed telemetry data, including traces, metrics, and logs, to any OpenTelemetry-compatible backend.
Key features include:
- High-performance caching: Drastically improve website and API response times.
- Modern Observability: Utilize the VCOT tool for deep insights via OpenTelemetry.
- Independent FOSS Project: Managed by a community-driven association, ensuring it remains free and open source.
- Proven and Mature: Built on a foundation of 20 years of development and real-world use.
