An AI coding assistant writes, edits or reviews code alongside you. This shelf tags 100 tools directly — which is exactly why the label is close to useless on its own: it covers products that share almost nothing beyond the adjective. The parent hub list also includes tools from child shelves (code-review-ai, chat-based-coding, inline-completion), so the grid below can show more than those 100 direct tags. Start by deciding which kind of assistant you are shopping for.
The division that matters is not which model sits underneath — most of these now run several — but where the tool lives and how much it may do before it asks. Four shapes cover almost everything here. Inline completion inside an editor you already use: GitHub Copilot, 88/100 in GitHub Copilot, free for 2,000 completions a month and $10/mo for Pro. An AI-native editor that owns the whole window: Cursor, 91/100 in Cursor, which appears in 42 of the 589 published comparisons — more than any other tool on this page. A terminal-resident agent that edits files and runs commands on its own: Claude Code at 92/100 (Claude Code), Aider at 83/100 and free if you bring your own API key. And an asynchronous reviewer that never touches your editor but comments on pull requests: CodeRabbit, 88/100, free for public repos and $24/user/mo after; Greptile, 85/100, $30/seat/mo with 50 reviews included.
Those four shapes stack without redundancy — an authoring tool plus a review bot is a coherent setup. Two tools of the same shape is where the budget leaks. Quality and security gates such as Semgrep (87/100), SonarQube (87/100) and Snyk (86/100) may still appear in this parent list via child shelves when they ship AI-assisted analysis — they are not coding-authoring assistants tagged on this shelf itself.
Consolidation was the story of 2026. Six tools from this category sit in the graveyard, three of them retired this year: Continue was acquired by Cursor and its standalone product discontinued on 18 June 2026, the Roo Code extension shut down on 15 May 2026 with its GitHub repository archived, and Codeball's PR-triage product went dark on 12 June 2026. Kite (2022), GitHub Copilot X (2024) and Phind fill out the list. Read that as a warning about picking on novelty: the survivors are mostly the tools with a business model you can name.
Coverage on the tools tagged here is unusually deep — 65 of the 100 have a scored review — so the practical route is to pick your shape first, open the review of the two or three candidates in it, and only then look at price. Where two tools are close, the head-to-head comparison pages will usually be more decisive than either review alone.
