CoreWeave, a leading AI cloud, has added Bufstream to its internal platform as part of the W&B Models and Weave product lines.Fri, 08 May 2026 00:00:00 GMThttps://buf.build/blog/protobuf-lsphttps://buf.build/blog/protobuf-lspBuf is proud to announce the first fully-featured, production-grade LSP server for Protobuf. The Language Server Protocol is the standard API for integrating language support into your favorite IDE or text editor, such as VSCode, IntelliJ, or Neovim. An LSP server provides the smarts that power go to definition, code completion, finding references, and semantics-aware syntax highlighting.Wed, 14 Jan 2026 00:00:00 GMThttps://buf.build/blog/protovalidate-v1https://buf.build/blog/protovalidate-v1After two years of development, we're proud to announce that Protovalidate has reached v1.0. Protovalidate is the semantic validation library for Protobuf. Protobuf gives you the structure of your data, but Protovalidate ensures the quality of your data. Without semantic validation, you're stuck writing the same validation logic over and over again across every service that consumes your messages. With Protovalidate, you define your validation rules once, directly on your schemas, and they're enforced everywhere.Fri, 12 Sep 2025 00:00:00 GMThttps://buf.build/blog/buf-custom-lint-breaking-change-pluginshttps://buf.build/blog/buf-custom-lint-breaking-change-pluginsBuf is introducing custom lint and breaking change plugins via the Bufplugin framework.

We joined the CNCF to demonstrate our deep commitment to sustainably and responsibly growing Connect as a well-governed and community-led open source project. Today, Connect integrates seamlessly with gRPC systems in production at companies of all sizes, such as CrowdStrike, PlanetScale, RedPanda, Chick-fil-A, BlueSky, and Dropbox.Tue, 04 Jun 2024 00:00:00 GMThttps://buf.build/blog/enhanced-buf-push-bsr-uihttps://buf.build/blog/enhanced-buf-push-bsr-uiWe've made it easier to onboard and use the BSR with improved support for monorepos, tighter integration with source control providers, and a new BSR UI that is more polished and has improved accessibility.Fri, 17 May 2024 00:00:00 GMThttps://buf.build/blog/protobuf-editions-are-herehttps://buf.build/blog/protobuf-editions-are-hereMost Protobuf users should ignore Editions and continue using proto3. If you become an early adopter, we’ve been working closely with Google to ensure that Buf will support editions as soon as they’re generally available.Thu, 09 May 2024 00:00:00 GMThttps://buf.build/blog/kong-insomnia-grpc-bsr-supporthttps://buf.build/blog/kong-insomnia-grpc-bsr-supportKong Insomnia’s 9.0 release includes integrated support for the Buf Schema Registry.
