Interesting tools

Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.

Skir

Declarative language for types & APIs.

What we like

Define the schema then generate idiomatic, type-safe code (Python, Go, Java, Rust, TS, etc). Dynamic serialization options e.g. binary or JSON. VS Code extension & LSP tooling. Supports backwards compatibility when changing schemas.

What we don't like

Compile-time errors if you add a field, but don’t regenerate the code - this is the opposite to protobuf which handles it by defaulting values. This may be better, depending on your philosophy.

Atomic

Knowledge graph.

What we like

Local, open source, markdown-based knowledge base. Auto-generates wiki articles from tags. Built-in semantic search with vector embeddings. Supports different types e.g. markdown notes, web clips, articles. Supports MCP. Can be an HTTP server without a desktop UI.

What we don't like

Everything is self hosted so you need to do some setup work. This is also a benefit.
