Cursor or Claude Code? Not a contest — two tools for two different minds

Clients and new engineers ask us the same question: “which one is better?”. The honest answer after a year of using both daily on projects like Umbrella and the TtaKkaa POS suite: the question is wrong. The two tools do not compete for the same chair; one sits next to you, the other works in the next room.

Cursor: when you are the one driving

Cursor is an editor, and that is not a passing remark. When you are inside a file you know, and want a smart completion, a refactor of a function, or an explanation of an obscure part of legacy code — you want the tool in front of your eyes, on the same line, at the same rhythm. Restructuring the tables screen of TtaKkaa Cashier in Flutter was “visual” work: see, tweak, run, repeat. That is Cursor at home.

Claude Code: when you want to delegate a whole task

Claude Code does not sit in the editor; it sits in the terminal and behaves as an agent. You give it a goal and boundaries and it goes: reads dozens of files, runs the tests, edits, re-runs, and returns with a report. When we had to migrate the Umbrella store from huge PNGs to WebP, rewriting every call site and regenerating the srcsets, that was not line-by-line work. It was a task to delegate. The agent finished what would have taken two days in fifty minutes, with a PR ready for review.

The decision table on our wall

• I know the file and I know what I want: Cursor.
• I know the goal but not every file: Claude Code.
• A change touching more than ten files: Claude Code first, Cursor for the finishing touches.
• Learning a new library while writing: Cursor, because learning happens by seeing.
• Repetitive boring work (translations, tests, formatting): Claude Code, no hesitation.

The trap we fell into

Using an autonomous agent for a tiny edit is like hiring a truck to deliver a letter.

At first we delegated everything to the agent, even colour changes. The result: waiting, cost, and a sense of lost control. The opposite trap is real too: trying to migrate a whole database through editor completions exhausts you and makes mistakes. The new skill is not “writing the prompt”; it is matching the tool to the size of the task.

What about the team?

More important than tools: agreement. Ours is simple — every agent-written PR carries a clear label, and every rules file (.cursor/rules or CLAUDE.md) is reviewed like code. Both tools share nearly the same file, so do not write the rules twice.
