KLAUSSY

Run Claude Code across every worktree.
In one window.

For the 20× developer.

Klaussy is a desktop app for macOS, Windows, and Linux that orchestrates multiple Claude Code sessions across git worktrees, reviews pull requests with AI, and offers tab-autocomplete from a local model — nothing per-keystroke ever leaves your machine.

Free to try. $39 lifetime access unlocks an access key for every platform.

What it does

Parallel worktrees, one view

Spawn a worktree per task, each with its own Claude Code instance. Columns, grid, or single-pane view. No more cd juggling.

Auto-debug CI failures

Klaussy connects to your PR's CI; one click pulls the failing job's logs and Claude returns root cause + suggested fix, applied straight to the worktree.

Full PR review surface

Pull in any PR, read the diff with inline comments, run an AI review that breaks into per-finding cards — ignore, implement, or append to PR.

Plan · Debug · Review

Every worktree has a dropdown that spawns a dedicated Claude tab running Claude skills to plan and debug, or a multi-phase PR review — same worktree, no context loss.

Inline AI — locally

Tab-autocomplete powered by qwen2.5-coder via Ollama. ~100ms latency. No code leaves your laptop.

Built-in editor

Monaco editor with LSP diagnostics. Edit and commit straight from the diff panel. AI-generated commit messages optional.

See it in action

Left: a Review action running on one worktree. Middle: another worktree idling. Right: a live GitHub PR with inline comment threads and a review composer.

Klaussy with parallel Claude Code terminals, a Review action in flight on the left, and a GitHub PR review surface on the right showing inline comment threads.

Debugging a failing CI check: click Debug on the red row and Claude pulls the job logs, points at the exact line, and proposes a fix. Ask follow-ups in the chat, then click Fix this to have Claude apply it in the PR worktree.

Klaussy's Checks tab showing a failing 'Lint, format, build' run with its file:line annotations expanded. Below, the Debug panel shows Claude's three-part analysis (what broke, caused-by-this-PR, fix) and a chat composer for follow-up questions, plus 'Fix this' and 'Open as task' buttons.

AI PR review: each finding is its own card with severity, file:line location, the offending code, and a written critique. Per-finding actions: Ignore, Add to PR, Claude implement, or open a chat with Ask Claude / Claude investigate.

A High-severity finding in the Review tab pointing at src/hooks/useSpeechRecognition.js:97-112, with a code block, written comment explaining the swallowed-errors bug, and a row of action buttons including Copy, Claude investigate, Ask Claude, Ignore, Add to PR, and Claude implement.

What you need

  • macOS 12 (Monterey) or later — Apple Silicon or Intel — Windows 10/11, or Ubuntu 22.04+ (other modern Linux distros generally work).
  • Claude Code CLI installed and authenticated. Klaussy orchestrates claude — it doesn't replace it.
  • GitHub CLI (gh) authenticated. Required for PR review features.
  • Ollama (optional). Only needed if you opt into local inline autocomplete. On macOS, Klaussy can install it via Homebrew; on Windows/Linux, install from ollama.com.

FAQ

Does my code get sent to third parties?

When you use Claude features, prompts + repo context go to Anthropic via the claude CLI you already trust. GitHub operations go through your local gh. Inline autocomplete runs entirely locally via Ollama and qwen2.5-coder:1.5b — nothing per-keystroke leaves your machine. We don't run a server of our own.

Do I need a Claude subscription?

You need whatever plan your claude CLI is configured for. Klaussy doesn't bill separately for AI usage — your purchase is a one-time license for the app itself.

How does the access key work?

After purchase you'll receive a license key. Paste it into Klaussy → Settings → License once, on any of your machines. The key is tied to you, not to a single OS — the same key activates Klaussy on macOS, Windows, and Linux.

What does “lifetime” mean here?

One-time payment, no subscription. You get every future update to Klaussy at no extra cost for as long as the app exists. AI usage (Claude, GitHub) still runs on your own accounts.

Which platforms are supported?

macOS 12+ (Apple Silicon and Intel), Windows 10/11, and Ubuntu 22.04+ (other modern Linux distros generally work). All builds are signed where the platform supports it.

Why the 2 GB download prompt for inline autocomplete?

~500 MB is Ollama's runtime; ~1 GB is the qwen2.5-coder:1.5b model weights. You only see this prompt if you opt in — otherwise a free word-based completer handles Tab.

What happens to my data if I uninstall?

On macOS, remove ~/Library/Application Support/Klaussy and ~/Library/Logs/Klaussy. On Windows, remove %APPDATA%\Klaussy. On Linux, remove ~/.config/Klaussy and ~/.local/share/Klaussy. Ollama and its models persist independently — uninstall it through your package manager and remove ~/.ollama.

Is this open source?

The application itself is commercial, closed-source. Feedback and bug reports live in a public repo (this one). The bundled open-source components are listed in About → Licenses.

How do I report a bug or request a feature?

Open an issue in this repo, or drop it in the Discord. Both get read.
