How we rank: tools are ordered by the balance of positive vs. negative recurring points in sampled posts, weighted by how many posts discuss them here. Tools with no posts are listed after, unranked. We show what people say, not who said it. Scenario name evidence: Google autocomplete: "open source ai coding agent github", "open source ai coding assistant".
