Continue.dev Review 2026: Open Source AI Coding Assistant

The modern development workflow is a constant dance between focus and context switching. Developers strive to stay “in the zone,” but repetitive coding tasks, debugging, refactoring, and even writing documentation often pull them away from their core problem-solving. While AI coding assistants have emerged as powerful allies, many require leaving the IDE, copying code, or are tied to specific, often proprietary, models. This is where Continue.dev enters the picture: an open-source, IDE-native AI coding assistant designed to keep developers in their flow by integrating large language models directly into their existing environment, offering strong flexibility and control over the AI backend. It’s for any developer looking to supercharge their coding efficiency without sacrificing privacy or vendor choice. ...
