// EDITOR'S TAKE
OpenHands is the closest match, since it runs agents in a sandbox that can take an issue and produce a pull request rather than only assisting inside the editor. opencode and Aider keep a human in the loop at the terminal and are far more predictable day to day, while SWE-agent is really a research harness tuned for benchmark-style issue solving.
