Sweep today is an AI assistant for JetBrains IDEs (IntelliJ, PyCharm, WebStorm, and more): next-edit autocomplete plus an integrated coding agent that searches your codebase, edits code, and runs tests and linters in the editor, using Sweep's own models. (Sweep originally shipped a GitHub issue-to-PR bot; that is now its legacy product.)
Fleet operates across the entire development lifecycle, headless and outside any editor. A developer agent handles coding, a reviewer agent approves or requests changes, and a release-manager agent handles the merge and labeling — all triggered automatically by GitHub label changes through Fleet's watcher daemon.
