Server configuration scripts for transparent WebP image delivery via Accept header negotiation.
WebP with Accept negotiation is a collection of server configuration scripts that enable automatic WebP image delivery based on client support. It detects if a browser accepts WebP via the Accept header and serves WebP assets transparently, reducing image file sizes for better performance. This approach allows existing applications to benefit from WebP without code modifications.
Web developers, system administrators, and DevOps engineers who manage web servers and want to optimize image delivery performance with WebP.
It provides a drop-in solution for WebP support through server configurations, eliminating the need to modify application code. Developers choose it for its simplicity, compatibility with existing setups, and performance gains from smaller WebP files.

As per the README, it enables transparent WebP serving without modifying existing applications, making it a drop-in solution for legacy systems.
Serves smaller WebP files to compatible browsers, reducing bandwidth and improving page load times, as highlighted in the value proposition.
Appends 'Vary: Accept' to client responses, ensuring correct caching behavior for different browsers, as specified in the key features.
Configures as a proxy to forward WebP capability via 'WebP: true' headers, allowing backend servers to adapt without changes.
Only includes ready-to-use configurations for Nginx and Varnish; other servers require manual adaptation, as admitted in the README with 'What about server X?'.
Assumes WebP files are already on disk; lacks built-in dynamic conversion, adding overhead for image management and storage.
Depends on client Accept headers, which can be unreliable in proxied environments, potentially causing format misdelivery.
