I love Fastmail, but I don't understand why they chose Electron for this. It's totally fair that they want to keep it web-based, but why ship a 318 MB memory hog? Why not something lighter like Tauri or a custom wrapper like Fastmate [1] did?
I’ve been looking for something like this, but closer to the Claude Code philosophy of a strong, terminal-first workflow. What I really want is a "Claude Code Manager" that can spin up new git worktrees, manage multiple instances, and let me jump between them - no heavy UI abstraction.
I’ve noticed these UIs tend to strip away native features (plan mode, sub-agents etc.). A thin layer that preserves Claude Code’s built-ins while orchestrating instances, worktrees, and branches from the shell would be ideal for me.
