GitHub Copilot
Human84
Agent72
GitHub Copilot is the completion and chat assistant inside VS Code, JetBrains, and github.com. Completions, Copilot Chat, and Copilot Workspace-style flows are the human job. Agent-style coding exists but is coupled to GitHub's identity and policy engine, which enterprises.
Replit
Human83
Agent75
Replit is a browser IDE, hosting platform, and increasingly an agent that builds apps from a prompt. The human magic is zero-setup: a REPL in a tab. Agent features (Agent, APIs, deployments) exist and are improving, but the source of truth is Replit's hosted environment.
