AI coding tools split into three jobs: completing code, editing whole codebases, and building apps from prompts. Pick by the job you do most.
In-editor completion
GitHub Copilot and Tabnine add suggestions inside your existing editor with minimal friction — Tabnine adds a privacy/on-prem focus for teams.
Codebase-aware agents
Cursor and Windsurf understand your whole project and make multi-file, agentic edits — best for refactoring and feature work.
Prompt-to-app builders
v0, Bolt.new and Lovable turn prompts into working full-stack apps, great for prototypes and non-developers.
