GitHub Copilot

Paid

GitHub Copilot is an AI pair programmer that suggests code as you type, inside VS Code, JetBrains IDEs, Neovim and GitHub itself. It completes whole lines and functions from context, answers questions about your repository in chat, and can propose fixes for failing tests or review pull requests. Copilot Workspace and the coding agent extend it to multi-step tasks. It supports several underlying models and works with most popular programming languages. A free tier offers limited completions and chat requests; paid plans raise limits and add enterprise controls, including policy management and audit logs. It is the most widely adopted coding assistant and integrates tightly with GitHub workflows.

Cursor

Freemium✦ Featured

Cursor is an AI-first code editor built on VS Code, so existing extensions and keybindings carry over. It adds inline AI edits, a chat panel that can see your codebase, and an agent mode that plans and applies multi-file changes from a natural-language request. Tab completion predicts multi-line edits, and you can reference files, docs and symbols with @-mentions. It supports popular models from several providers and lets you bring your own API key. The free tier includes limited AI requests; paid plans raise limits and unlock the agent. Teams that want AI assistance without leaving a familiar editor tend to adopt it quickly.

Ollama

Free

Ollama lets you run open-weight language models on your own machine with a single command. It handles model downloads, GPU acceleration and local serving, exposing an API compatible with common OpenAI-style clients. The library includes models for chat, coding, vision and embeddings, from laptop-friendly options to larger models for workstations. Because everything runs locally, prompts and data never leave your computer — useful for confidential work, offline use and experimentation without per-token costs. It runs on macOS, Linux and Windows, and integrates with tools like Open WebUI. It is the simplest way to start with local LLMs, though large models need substantial RAM and a capable GPU.
