Best Codeium Alternatives

Twinny is a free, open-source AI code completion extension for VS Code that works with any OpenAI API-compatible endpoint including local models via Ollama. It provides real-time inline suggestions, a sidebar chat for code discussion, workspace embeddings for context-aware completions, and a decentralized P2P inference network. A privacy-first alternative to GitHub Copilot with zero licensing cost.

Entire is an AI-native code management platform designed for teams managing fleets of AI coding agents. Founded by former GitHub CEO Thomas Dohmke, it records the reasoning and instructions behind AI-generated code alongside the code itself, making agent-written software easier to review, audit, and maintain. Launches with Checkpoints, an open-source CLI tool that logs prompts and token usage for Claude Code and Google Gemini CLI, with more agent integrations planned.
