GitHub Copilot is cheaper at $10/mo, against $30/mo.
AI code review on every pull request
AI completions and agents, native to GitHub
Copilot writes the code, CodeRabbit reviews it. Copilot is the cheaper and broader of the two at $10/mo Pro, and it does ship review on GitHub, but review is one feature among many. CodeRabbit does nothing else: line-by-line comments on every diff, suggested fixes, and it is free on open source. If you only buy one, buy Copilot. If review quality is the thing you are missing, add CodeRabbit.
