Aider is an open-source AI pair-programming tool for developers who want an agentic coding workflow directly in the terminal.

Continue is a wildly popular, entirely open-source AI coding assistant that operates as a highly flexible, deeply customizable extension for VS Code and JetBrains IDEs. Its fundamental philosophy is to provide developers with absolute, uncompromising control over their AI tooling. Rather than locking users into a specific, proprietary Large Language Model or a rigid monthly subscription, Continue allows developers to "bring their own AI." Users can seamlessly plug in API keys for powerful commercial models or connect the extension directly to locally hosted, completely private open-source models using tools like Ollama. The extension provides a highly intuitive, sidebar-based chat interface where developers can easily highlight specific blocks of code and ask the AI to explain, refactor, or debug the logic. However, Continue goes significantly further by offering a powerful, native autocomplete engine that functions beautifully alongside the chat interface. It also features a deeply innovative "slash command" system, allowing developers to create highly customized, easily repeatable AI workflows—such as automatically generating specific unit test structures or translating code comments into different languages with a single keystroke. Because it is completely open-source and deeply extensible, Continue is heavily favored by privacy-conscious developers, massive enterprise security teams, and researchers who require absolute data sovereignty over their proprietary codebases. It is backed by a massive, highly active community that constantly develops new integrations and shares customized prompt templates. Continue represents the definitive open-source alternative to proprietary AI assistants, ensuring that the future of intelligent software development remains accessible, transparent, and highly customizable.
