Open-source GitHub Copilot alternative — any model, VS Code and JetBrains, fully customizable.
Continue is the most widely adopted open-source Copilot alternative — a VS Code and JetBrains extension providing inline completions and conversational AI coding assistance with any model. Claude, GPT-4, Gemini, or local models via Ollama — Continue works with all of them. For developers who want GitHub Copilot's in-editor experience without the subscription or the data-sharing concerns, Continue is the open-source standard.
Continue is an open-source AI coding extension available for both VS Code and JetBrains IDEs — making it the only open-source option that works across both major editor ecosystems. It provides inline code completion (Tab), AI chat grounded in the codebase, inline editing of selected code, and context-aware documentation references. Continue's model flexibility is its primary advantage over GitHub Copilot: configure it with any API-accessible model (Claude, GPT-4, Gemini, Mistral, Cohere) or any local model via Ollama — and switch between them in seconds. For organizations with data sovereignty requirements, running Continue with a local Ollama model provides Copilot-equivalent in-editor AI assistance with no data leaving the building. Continue is free — the only costs are API calls if using cloud models. The configuration is YAML-based and highly flexible: define which models handle completion vs. chat, set context providers (docs, web search, GitHub issues), and configure keyboard shortcuts to match your workflow. For developers who want a transparent, customizable, cost-flexible alternative to GitHub Copilot or who have principled positions on open-source tooling, Continue is the right choice.
Configure Continue with Ollama running Qwen2.5-Coder or Code Llama locally — get inline completions and AI chat in VS Code or JetBrains with no API calls and no data leaving the machine. For enterprises with data residency requirements or developers working on classified codebases, this provides practical AI coding assistance within privacy constraints.
For JetBrains users (IntelliJ, PyCharm, WebStorm, GoLand), Continue is the primary open-source AI coding option — GitHub Copilot works in JetBrains but is a paid subscription with OpenAI's data terms. Continue provides comparable inline completion and chat quality while allowing model switching, local options, and full configuration transparency.
Codeium is a commercial product with a generous free tier and polished UX — easier to set up, better out-of-the-box completion quality. Continue is fully open source with unlimited model flexibility and local model support — better for privacy requirements, customization, and JetBrains users who want open-source tooling. For straightforward Copilot replacement, Codeium is easier. For full control and privacy, Continue is better.
The AI IDE that developers actually switch to — codebase-aware agents, Tab completion, and Composer in one VS Code fork.
