One API to Rule Them All: Migrating from zod-openapi to ConnectRPC We're unifying our internal tRPC API and public REST API into a single ConnectRPC service. Here's how we're doing it—and how AI is accelerating the migration.

We are going full connectRPC by @buf.build

Protovalidate is now v1.0 After 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 dat...

Big milestone! Protovalidate just hit v1.0

It's big news for the Protobuf semantic validation library trusted by Microsoft, GitLab, Nike and 1000's more to:
✅ Define validation rules only once
✅ Enforce everywhere (Go, Java, Python, C++, TypeScript)

Finishing Kafka: LinkedIn proved it works, Buf makes it simple Stanislav Kozlovski's deep dive into the Kafka creation story appeared last weekend. It detailed how LinkedIn solved data problems with Kafka and also revealed three remaining challenges—schema evolut...

LinkedIn's Kafka origin story reveals 3 gaps: Schema evolution, plug-and-play integration, and governance.

Buf complete that vision:

- CLI breaking change detection
- Bufstream broker-side schema awareness
- BSR organization-wide governance

Finish what Kafka started. ⚡

🚨 With streaming data, any record flowing through your pipelines is a potential point of failure. When schemas drift or malformed data sneaks through, your downstream systems don't just slow down—they break.

TL;DR: The first 15 field numbers are special: most runtimes will decode them much faster than the other field numbers. When designing a message type for decoding performance, it’s good to use these field numbers on fields that are almost always present.

Tip of the week #8: Never use required Don’t use 'required' to modify fields—you won’t be able to get rid of it later when you realize it was a bad idea.

Tip of the week #7: Scoping it out buf convert and protoscope are powerful tools for examining and debugging wire format dumps.

TL;DR: buf convert is a powerful tool for examining wire format dumps, by converting them to JSON and using existing JSON analysis tooling. protoscope can be used for lower-level analysis, such debugging messages that have been corrupted.
