Mulpex

About

Hi, I'm Gidi Dafner. I'm a full-stack engineer based in Israel and the author of Mulpex.

My day job is partner and head of development at DreamVPS, where I've spent the last few years building cloud infrastructure from scratch — a virtual server management platform, a zero-trust security product (Cloudraw), and a managed WordPress ecosystem (ClickPress). Most of what I write runs on Node.js and React, backed by MongoDB and Redis.

Mulpex started as a tool for myself. I run a lot of parallel Claude Code sessions, and iTerm2 + zsh kept fighting Claude over Ctrl-keys and readline. Owning the keyboard layer turned out to need a real GUI, so I built one. The git-worktree-per-tab thing came next, because once you have multiple Claude tabs you immediately want them on different branches.

Then everything that follows from actually living in a worktree-per-tab world started piling up: per-branch dev servers on auto-allocated ports so two features run side by side in the browser; pre-deploy review with selection-anchored Ask-Claude so the small questions get answered before push instead of in code review; loose tabs for the messy non-branchable work; kebab-case tab titles from a side-channel Haiku call so the sidebar stays scannable when ten Claudes are running. Parallel Claude in worktrees is now a category — Anthropic ships their own; there are a dozen third-party tools — so what Mulpex is really about is the composition and the opinions, not any single feature.
