Autocomplete and coding assistance with broad editor support.
Our verdict
Codeium
Codeium is the strongest free option for AI coding assistance. Unlimited individual use, broad IDE support, and completion quality close enough to Copilot that most engineers won't notice the gap day-to-day. For solo developers or budget-conscious teams, the default pick.
