Git is generally insufferable when it comes to these. Diffing YAMLs is even worse, and it gets downright hideous when the specific document you're working with betrays YAML's rules about orderedness (the document is order invariant, while YAML is ordered). In that case, even most semantic diffing tools become unusable.
I've been recently using dyff [0] to diff YAMLs in an order invariant way, and it's been absolutely liberating. Couldn't help with version control, but it's still night and day.

libopenapi
libopenapi is a fully featured, high performance OpenAPI 3.2, 3.1, 3.0, Overlays and Arazzo parser, library, validator and toolkit for go applications.
Project mention: Your MCP Server Is Eating Your Context Window. There's a Simpler Way | dev.to | 2026-03-16OpenAPI-native, no code generation. The binary embeds the latest Apideck Unified API spec. On startup, it parses the spec with libopenapi and builds commands for every API group, resource, and operation. When the API adds new endpoints, apideck sync pulls the latest spec. No SDK regeneration, no version bumps.

That’s why I created godiffyaml, a tool designed to solve this exact issue. Whether you’re a developer, DevOps engineer, or system admin, godiffyaml makes diffing multi-document YAML files painless.
