Code Assistant (2026)

AI-powered code assistants for writing, completing, reviewing, and refactoring code. Compare the best coding tools for developers.

112 tools

Code assistant tools help developers write, understand, review, and refactor software faster. This category includes coding copilots, terminal agents, IDE-native assistants, and developer workflows that reduce repetitive work while keeping engineers in control.

On AgentIndex, you can compare open-source and commercial code assistants by stars, licenses, update cadence, and supported workflows. If you are choosing between tools for pair programming, code review, repository search, or automated edits, this page gives you a stronger starting point than a generic search result.
