devsync

Edit locally, run remotely.

devsync is for working on one machine and running the code on another: a GPU server, a lab workstation, a cloud VM, an embedded board. It is built for networks that drop.

• You (or a coding agent such as Claude Code) edit files locally, at full speed, with any editor. Nothing freezes when the network does.
• devsync exec -- pytest sends the changed files, runs the command on the remote in the matching directory, streams the output, keeps the exit code, and copies back files the command generated.
• Commands run detached on the remote. Every exchange is a short ssh session, so a dropped connection only delays output and never kills the command. Results are collected into .devsync/jobs/<id>/ on your machine.
• Nothing needs to be installed on the remote: devsync uploads its own small static agent over ssh.
