At the time of writing, HTTP/3 is supported by 30.4% of the top 10 million websites. This market penetration is astounding, but it seems like all of this progress has been possible almost exclusively by work on browsers, load balancers and CDN providers. What about the backend? How’s HTTP/3 doing there? The answer, sadly, is not as incredible.

Because of this, I have been very interested in HTTP/3 in the context of gRPC. While gRPC has been instrumental in driving the adoption of HTTP/2, the same isn’t true for HTTP/3 even though HTTP/3 promises several benefits that all seem to apply exceptionally well to gRPC services.

In this post, we’ll dive into what HTTP/3 is and explore the compelling reasons why it’s an ideal fit for gRPC applications. We’ll uncover the technical advancements that promise to make HTTP/3 faster, more reliable, and more secure. But we won’t stop at theory; we’ll get our hands dirty with practical examples in Go, demonstrating how to set up and test gRPC servers and clients over HTTP/3.

By the end of this journey, you’ll have a solid understanding of the benefits HTTP/3 brings to gRPC, the tools available to start using it today, and the potential it holds for the future of API development. So, fasten your seatbelts and get ready to experience the next generation of network protocols!
