6. Codex by OpenAI

What it does: Codex can generate code based on natural language prompts, allowing you to describe what you want in plain English.

Pricing: $0.01 per 1,000 tokens used.

Best for: Developers who want to quickly prototype features without writing boilerplate code.

Limitations: It can misinterpret prompts, leading to incorrect code outputs.

Our take: Codex can speed up our initial coding phases, but we always need to refine the generated code.

7. DeepCode

What it does: DeepCode uses AI to review your code and provide feedback on potential bugs and security vulnerabilities.

Pricing: Free for open-source; $19/mo for private repositories.

Best for: Developers focused on maintaining code quality and security.

Limitations: It may not catch every issue, especially in larger codebases.

Our take: We find DeepCode invaluable for enhancing security, but it’s not a complete substitute for manual reviews.
