The Agentic
Development Environment
Delegate the code. Control the outcome.
SimpleEdit is built around reviewing code agents have written — not writing it yourself. Steer multiple Claude Code sessions across worktrees, inspect diffs, and ship faster.
Built for the agentic workflow
When you run agents in parallel, your job changes. SimpleEdit is designed for that shift.
Diff-first UI
Commit review and staged change inspection are first-class citizens, not buried in a menu. The moment you click a commit, a side-by-side Monaco diff fills the pane.
Multi-worktree by design
Run separate agents on separate branches simultaneously. Each pane tracks its own worktree with independent editor state — review a diff in one while an agent runs in the other.
Live agent awareness
See which files Claude Code has touched and what it's currently doing — without leaving your review flow. File tree highlights update in real time as the agent works.
Contextual agent interaction
Send questions about a specific commit or diff directly to a Claude terminal, with context pre-filled. Select a line of code and ask the agent to reconsider it — right from the editor.
Two agents.
Two branches.
One screen.
SimpleEdit works best with a bare git repository and git worktrees — one per agent session. Open the repo once and get a pane for each branch. The git log, file tree, editor, and terminal are all per-pane.
Understand any commit
in seconds
Click Tour on any commit and Claude narrates the changeset — an overview, then a topic-by-topic walkthrough of every file touched. Streamed live, cached for instant replay.
High-level overview before diving into code
Grouped by topic, not file order
Inline compact diffs alongside the explanation
Cached on disk — revisit without re-running Claude
Question the diff,
not the codebase
Select any line in the diff, press ⌘I, and ask Claude about it. The commit hash, file, and selected lines are sent as context — no copy-pasting, no context loss.
Route the question to any running Claude Code terminal. The agent sees exactly what you see, so its answer is precise.
A real editor,
not just a viewer
Monaco Editor under the hood — the same engine as VS Code. LSP-powered diagnostics, hover info, and go-to-definition for TypeScript, JavaScript, CSS, JSON, Rust, Python, and Go.
