Twin Scores side by side
GitHub
Human91
Agent94
GitHub is the default public source host and a full DevOps surface: issues, PRs, Actions, Packages, Codespaces, and security scanning. Humans live in the PR timeline. Agents live in the REST and GraphQL APIs, Checks, and workflow YAML. Few products have a more complete twin:.
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.
