First-party only — a session id and where you arrived from, so we can tell which pages are worth writing more of. No advertising, no third-party trackers, nothing that follows you off this site.
Both are on this list because they are genuinely good at something. The question is which something you need. Below is the factual comparison, then the honest answer about who each one is for.

| Best for | Multi-file work in a repo you can describe well — the more context you put in CLAUDE.md, the further ahead it gets. | Well-specified, self-contained tickets a team would otherwise queue for weeks. |
Configuration is a first-class feature — memory files, skills, hooks and permissions are documented and versionable in the repo
Works on the real filesystem and the real shell, so it can run your tests instead of guessing whether they pass
Subagents let you fan work out without polluting the main context window
Anthropic models only — you cannot point it at a different provider
Terminal-first, which is a poor fit if you want inline autocomplete while you type
Heavy usage on the $20 plan runs into limits fast; the useful tiers cost more
Genuinely asynchronous — you assign and walk away
Slack-native assignment fits how teams already triage
Its own environment means no local setup
Cost is an order of magnitude above assistant tooling
Success depends heavily on how well the ticket is written
Least suitable of anything here for exploratory work
Pick Claude Code if multi-file work in a repo you can describe well — the more context you put in CLAUDE.md, the further ahead it gets.
Pick Devin if well-specified, self-contained tickets a team would otherwise queue for weeks.
And a thing worth saying plainly: the gap between these two is smaller than the gap between a repo that tells an agent what it is and one that does not. If you are choosing between them to fix inconsistent output, the tool is probably not the variable. The free Foundations track covers the part that is.
