Two code & development tools, one decision. Here is the honest split.
| Cursor | Tabnine | |
|---|---|---|
| Pricing | Free trial | Free plan |
| Best at | Multi-file changes, refactors, and "build me this feature" prompts that touch many files. | Companies that cannot send code to third-party clouds but still want AI completion. |
| In short | An AI-first code editor that can edit across your whole codebase, not just autocomplete a line. | A privacy-focused AI code completer that can run on your own infrastructure with team-trained models. |
| On Atlas | 3 starter prompts | 3 starter prompts |
Pick Cursor when the job is Multi-file changes, refactors, and "build me this feature" prompts that touch many files.. Pick Tabnine when the job is Companies that cannot send code to third-party clouds but still want AI completion.. Still torn? Run one real task through both free tiers. An hour of testing beats a week of reviews.
Here is my code: [paste code]. Find the three most likely bugs or edge cases, explain each in one sentence, then show the fixed code with tests.
