Most "best AI tools" lists online are affiliate farms. We test tools on real dev workflows — shipping features, debugging production issues, cutting invoice generation time — and write down what actually worked.
Reviews below are grouped by use case. Every review names the version tested, the stack it was tested in, and what the tool could not do. If you see a tool missing, it either failed testing or we have not finished reviewing it yet.
Three frontier models compete for production workloads in June 2026. Claude Opus 4.8 leads on coding (88.6% SWE-Bench), Gemini 3.5 Pro owns ultra-long context (2M tokens), and GPT-5.6 targets agentic tasks. Here's the decision framework.
OpenCode is the most-starred open-source AI coding agent in history — and in a 38-task production benchmark, it beat Claude Code on debugging and documentation while losing on complex refactors. Here's the full breakdown, cost model, and who should actually switch.
Zhipu's GLM-5.2 is live across all Z.ai Coding Plan tiers with a 1M-token context window — five times wider than GLM-5.1. It shipped without a single published benchmark. Here's what that means, and how to wire it into Claude Code, Cline, or OpenClaw today.
