Anysphere · Coding Agents
Cursor is the most popular AI-powered IDE, built as a fork of VS Code with deep model integration across autocomplete, chat, and inline edits. It supports multiple frontier models and has become the reference point for all coding agent comparisons. Its CMD+K and Composer features enable both single-file edits and full multi-file agentic workflows.
Cognition · Coding Agents
Devin was the first publicly announced "AI software engineer," capable of planning and executing full engineering tasks across a sandboxed environment with browser, terminal, and code editor. While early demos generated enormous hype, real-world users report it excels at well-scoped tasks but struggles with ambiguous requirements. Controversy around its benchmark claims makes it one of the most debated agents on the platform.
Anthropic · Coding Agents
Claude Code is Anthropic's CLI-native agentic coding tool, running directly in the terminal with deep filesystem and shell access. It reads the entire codebase context and can autonomously edit files, run tests, and commit code — making it a favourite among power users who prefer a terminal-first workflow. Claude Code is widely regarded as the most capable agent for complex, multi-file refactors.

Most helpful published review per agent, pulled from current Ruling data.
Ruling editorial benchmark: Cursor remains the strongest default for product engineers who want chat, inline edits, and multi-file changes inside a familiar VS Code-style workflow. It is fastest when the codebase is already organized and the user can review each patch carefully. The main limitation is that large refactors still need a senior engineer shaping the plan and checking edge cases.
Ruling editorial benchmark: Devin is strongest when the ticket is narrow, the repo is accessible, and success can be checked with clear tests or acceptance criteria. It is less reliable when the task requires product judgment or deep organizational context. The product is important to benchmark because it defines the autonomous-software-engineer category, but buyers should evaluate output quality against cost carefully.
Ruling editorial benchmark: Claude Code is excellent when the workflow starts in the terminal and the task benefits from reading files, editing multiple paths, running tests, and iterating with explicit approval. It feels less like autocomplete and more like a supervised engineering partner. Teams should still budget for token usage and require human review before merging generated changes.
