Developer Guide

Picking the Right AI Coding Tool

The best tool depends on your language stack, IDE preference, and whether you need agentic or autocomplete AI.

🏗️

Autocomplete vs Agentic

Autocomplete tools (Copilot, Codeium) suggest code line-by-line. Agentic tools (Cursor, Windsurf) understand context and make multi-file changes autonomously.

🔒

Privacy Matters

Enterprise developers should evaluate whether code is sent to external servers. Tabnine and AWS CodeWhisperer offer on-prem options for compliance-sensitive teams.
