Buying checklist for AI coding & developer tools
- Match the tool to your editor (VS Code, JetBrains, terminal) and your main languages.
- Test it on your real codebase: context across many files matters more than single-function demos.
- Check privacy terms if your code is proprietary — some offer no-training or self-hosted options.
- For app builders, check whether you can export the code and host it yourself.
Keep in mind: Generated code can contain bugs and security issues. Review changes, run tests and never paste secrets such as API keys into prompts.
