Sells autonomous task completion rather than an editor. Acquired Windsurf in 2025, consolidating the middle of the coding market.
Tools that do comparable work, best fit first, drawn from the catalogue rather than hand-picked. Every one is listed whether or not there is money in it for us.
Best general option for explaining unfamiliar code, debugging a single file, or analysing a spreadsheet with real Python behind it.
View ChatGPT →Reads long files and whole error traces without losing the thread, which makes it good at explaining unfamiliar code and debugging in a chat window.
View Claude →Reviews pull requests line by line and leaves comments in the diff, with the reasoning attached rather than a score.
View CodeRabbit →The editor most professional developers have converged on. Understands a whole codebase, not just the open file.
View Cursor →The default, and the one already wired into the editor and the pull request your team uses. A free tier now covers light use.
View GitHub Copilot →Upload a spreadsheet and it writes and runs real code against it, showing the working rather than describing it.
View Julius AI →Where Devin sits in the wider category pages.
Strong fit — Programming, debugging, data analysis, spreadsheets, math, engineering, technical research.

Autonomy means less visibility into what changed — review discipline matters more, not less. Larger organisations may still be routed through sales rather than self-serve.
6 tools do comparable work: ChatGPT, Claude, CodeRabbit, Cursor, GitHub Copilot, Julius AI. 6 of them have a free plan.
