Tervia Lite: Terminal-first Git review companion

A lightweight diff and commit tool for terminal-only AI coding users who don't want to open a full editor

Problem

Heavy AI coding users increasingly run Claude Code or Codex in the terminal, and open VS Code almost only to review Git diffs. Keeping a full editor installed just for that wastes memory and disk. Existing terminal tools either do Git only or file browsing only — none combine terminal, diff review, and occasional manual edits in one lightweight place.

Solution

A single-binary or lightweight GUI tool that combines multi-tab/split terminals, Git diff staging by file or hunk plus commit, and simple file browsing with syntax-highlighted editing in one window. Not a full IDE — it serves the core loop of 'AI writes, I review changes, occasionally tweak a line, then commit,' with fast startup and low footprint.

Users

AI coding power users who live in the terminal, remote server developers, users on low-spec machines

MVP

Multi-tab and split terminals; sidebar Git diff with file/hunk staging and commit; file tree browsing with read-only syntax-highlighted preview; commit history and branch switching;

Revenue

Open-source core plus paid packaged builds (cross-platform installers, auto-updates, team config sync); or one-time license

Why now

AI coding is pushing many developers back to the terminal, reducing editor usage while review needs remain; big editors won't optimize for this narrow path, leaving room for an indie tool.
