Connect is already used in production by companies like CrowdStrike, PlanetScale, Redpanda, Chick-fil-A, Bluesky, and Dropbox. The post covers Connect's spec conformance testing (which found 22 conformance issues in Google's gRPC implementations), its simpler HTTP/1.1/2/3-compatible protocol, and calls for contributors to build support for Rust, Python, Ruby, Java, and Dart. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Connect RPC and how does it relate to gRPC? Connect RPC is a family of libraries from Buf for building browser- and gRPC-compatible HTTP APIs, positioned as a more open alternative to Google's gRPC. It generates server handlers, marshaling, routing, compression, and type-safe clients from a Protocol Buffer schema, and its 1.0 implementations are required to maintain 100% conformance with the gRPC and gRPC-web protocols. _Compare gRPC alternatives like Connect RPC and track ecosystem shifts on daily.dev._ ### Why did Connect RPC join the CNCF? Connect RPC joined the Cloud Native Computing Foundation to establish well-governed, community-led open source governance rather than remaining solely controlled by Buf. Under the new model, all repositories follow RFC-based evolution voted on by maintainers, including community contributors who now hold equal decision-making power alongside Buf-employed maintainers. _Follow open governance changes in projects like Connect RPC by staying current on daily.dev._ ### How many conformance issues were found in Google's gRPC implementations compared to Connect RPC? Testing identified at least 22 conformance issues across Google's generally available, v1.0 gRPC implementations, versus only a handful of mostly specification-ambiguity issues in Connect RPC, which have already been fixed. This was measured using a fully automated conformance suite validating implementations against both the Connect RPC and gRPC protocol specifications. _Weigh conformance and stability trade-offs between gRPC implementations using resources on daily.dev._ ## Similar posts on daily.dev - [connect-rust joins the Connect project · Buf](https://daily.dev/posts/connect-rust-joins-the-connect-project-buf-apuqzc6s4) · Buf Blog · 5 upvotes · 0 comments - [gRPC vs REST Is the Wrong Question · Buf](https://daily.dev/posts/grpc-vs-rest-is-the-wrong-question-buf-xe2qehlxz) · Buf Blog · 109 upvotes · 4 comments - [ConnectRPC: Generate Typed SDKs from Your GraphQL API](https://daily.dev/posts/connectrpc-generate-typed-sdks-from-your-graphql-api-cgx6z8ayk) · WunderGraph · 9 upvotes · 0 comments - [Cloudflare Workers and Containers now support inbound TCP connections and gRPC](https://daily.dev/posts/cloudflare-workers-and-containers-now-support-inbound-tcp-connections-and-grpc-ip5ywscgz) · Cloudflare · 6 upvotes · 0 comments - [Cloudflare Workers Accept Inbound TCP, with gRPC the First Protocol on Top](https://daily.dev/posts/cloudflare-workers-accept-inbound-tcp-with-grpc-the-first-protocol-on-top-pplojcdxn) · InfoQ · 0 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source), [#architecture](https://daily.dev/tags/architecture), [#grpc](https://daily.dev/tags/grpc), [#cncf](https://daily.dev/tags/cncf) [View this post on daily.dev](https://daily.dev/posts/connect-rpc-joins-cncf-grpc-you-can-bet-your-business-on-buf-o1tp8tykp) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Connect RPC joins CNCF: gRPC you can bet your business on · Buf","url":"https://daily.dev/posts/connect-rpc-joins-cncf-grpc-you-can-bet-your-business-on-buf-o1tp8tykp","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/connect-rpc-joins-cncf-grpc-you-can-bet-your-business-on-buf-o1tp8tykp"},"datePublished":"2026-08-23T07:20:08.772Z","dateModified":"2026-08-23T07:20:30.056Z","description":"Connect RPC, Buf's gRPC-compatible library family, has joined the Cloud Native Computing Foundation to strengthen its open governance and community-led...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7d480afd1605b53ea64418f9457dec22?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7d480afd1605b53ea64418f9457dec22?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Buf Blog","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Buf Blog","logo":"https://media.daily.dev/image/upload/s--2YBgo_Nm--/f_auto,q_auto/v1787469605/logos/buf?_a=BAMAMicg0","url":"https://daily.dev/sources/buf"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/connect-rpc-joins-cncf-grpc-you-can-bet-your-business-on-buf-o1tp8tykp","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"open-source,architecture,grpc,cncf","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Buf Blog","item":"https://daily.dev/sources/buf"},{"@type":"ListItem","position":3,"name":"Connect RPC joins CNCF: gRPC you can bet your business on · Buf"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/connect-rpc-joins-cncf-grpc-you-can-bet-your-business-on-buf-o1tp8tykp#faq","mainEntity":[{"@type":"Question","name":"What is Connect RPC and how does it relate to gRPC?","acceptedAnswer":{"@type":"Answer","text":"Connect RPC is a family of libraries from Buf for building browser- and gRPC-compatible HTTP APIs, positioned as a more open alternative to Google's gRPC.
