The author pushed each AI coding platform through complex full-scale applications with multiple revision rounds to test which ones break under pressure.
Describes a rigorous testing methodology beyond simple hello-world apps.
Each platform is graded on four categories worth 25 points each: UX/UI, AI agent prompt building efficiency, code export and deployment, and pricing and limitations.
The author establishes a consistent scoring framework for all tools.
Cursor scored 13 out of 25 for AI agent prompt building efficiency due to failures in following instructions and inconsistent execution under layered prompts.
The tool missed offline functionality, had a buggy theme toggle, and the redesign broke the layout.
Cursor's pricing score is 19 out of 25, with Pro plan at $16-20/month, but the credit-based billing change in June 2025 halved effective requests from ~500 to 225.
The switch to credit-based billing made usage less predictable and reduced the value of the $20 plan.
Windsurf scored 15 out of 25 for AI prompt building efficiency because it struggled with major structural changes and produced incomplete implementations.
It lacked placeholder data in the complex build and broke the layout when asked for a full redesign.
Base 44 received 25 out of 25 for deployment due to native web deployment, automatic authentication and database setup, and direct iOS/Android publishing.
Everything is built in, eliminating the need for external hosting or configuration.
Base 44's pricing ranges from $192 to $1,920 per year, scoring 18 out of 25 due to higher costs for advanced usage despite flat pricing and unlimited apps.
The all‑in‑one value is strong, but premium tiers make it less accessible for heavy users.
Only one platform, Base 44, can handle the full process of building, iterating, and deploying without things breaking, making it the best AI coding tool.
The other tools either lacked consistency, deployment integration, or broke under layered revisions.
