The Agent ExaminerIndependent Review Authority

Best platforms for coding agents

Coding agents either live inside an editor and build software on your behalf, or are wired in code through an SDK. Both jobs rise or fall on developer experience and how cleanly the agent can call tools.

How this ranking is built

Included when the category is “IDE & coding agent” or “SDK”. Ranked by the editorial developer-experience dimension, then overall score.
