FAQ
Which AI coding tool is fastest?
Cursor and Windsurf both use sub-second autocomplete. For agent runs that touch many files, Claude Code is slower per task but produces the most complete output.
Is GitHub Copilot worth it in 2026?
Yes for teams already on GitHub Enterprise. The compliance story and IDE coverage justify the seat cost. Solo devs typically prefer Cursor.
Can I use these tools offline?
Tabnine offers a self-hosted option that runs on your infrastructure. The other four require an internet connection.
