About KB Cafe

KB Cafe is a developer’s knowledge base, café-warm. KB is for Knowledge Base, the substance, the tools and references; Cafe is for the delivery: warm, fast, and made to be used, not wrestled with.

The domain has roots: kbcafe.com was a go-to developer resource in the early-to-mid 2000s, explaining the infrastructure of its era, RSS, feeds, and a deep shelf of C++/C#/.NET how-tos that people linked for years because they needed a reference. We brought it back, and rebuilt it for how we work today.

What’s here

• Tools: fast developer utilities that run entirely in your browser.
• AI Explained: clear references for modern AI infrastructure: context windows, MCP, RAG, embeddings, and the patterns behind agents.
• Reference: evergreen explainers on the fundamentals.
• Feeds: modern RSS/Atom/OPML tools, honoring the site’s heritage.

How we build

Everything runs client-side: nothing is uploaded, there are no accounts, and the tools work offline once loaded. We write references to be read once and remembered, and we don’t pad them with filler. The goal is simple: be the place developers cite when they need to explain how something works.
