Cloud-hosted agent that integrates directly with GitHub repos, plans before coding, reviews its own work, and opens PRs—replacing the need to switch contexts between your IDE and task management.

Summary
Shifts coding agents from synchronous IDE helpers to background workers that handle multi-step tasks asynchronously, freeing you from blocking on AI execution. The human-in-the-loop design lets you steer mid-execution without restarting, matching how real teams actually work.

Implementation verdict
Ready now via hosted version at swe.langchain.com—requires Anthropic API key and GitHub connection. Replaces manual task routing and PR creation for complex features; overkill for one-liners (they're working on a local CLI for that). Worth trying if you have substantial refactors or feature tasks to delegate.
