No winner has been declared. Run Cursor and Windsurf IDE against the same frozen task and publish the raw scores before recommending either one.
Has WhichAI declared which product is better for AI-assisted coding?
No. This page records narrowly sourced vendor facts and a test protocol. WhichAI has not run both products on the same frozen task, so there is no published winner.

| Pricing question | What do the current official plan, usage, and overage terms cost at your expected volume? | What do the current official plan, usage, and overage terms cost at your expected volume? |
| Decision question | Does Cursor produce the accepted output with fewer corrections, lower observed cost, or a better control fit on your frozen task? | Does Windsurf IDE produce the accepted output with fewer corrections, lower observed cost, or a better control fit on your frozen task? |
Freeze one task, its inputs, acceptance criteria, account state, model settings, and evaluator before the first run. Use the same number of trials for both products.
Declare a winner only when the run and a predeclared decision rule are published. A tie or a split decision by task is valid.
