What it does
Any agent, your choice
Run each task on Claude Code, OpenAI Codex, Google Gemini, or GitHub Copilot. Pick a default, switch per terminal, or run the same task in two agents side by side.
Parallel worktrees, one view
Spawn a worktree per task, each with its own agent 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 your agent 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 agent tab running Klaussy's guided Plan flow, a Debug pass, 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.
Debugging a failing CI check: click Debug on the red row and your agent 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 the agent apply it in the PR worktree.
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, Implement, or open a chat to Ask or Investigate — all run on your selected agent.
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).
- At least one agent CLI installed and authenticated — Claude Code, OpenAI Codex, Google Gemini, or GitHub Copilot. Klaussy orchestrates the agent you choose — 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 an agent, prompts + repo context go to that agent's provider via the CLI you already trust — Anthropic (Claude), OpenAI (Codex), Google (Gemini), or GitHub (Copilot). 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 subscription for the agents?
You need whatever plan each agent CLI you use is configured for — Claude, Codex, Gemini, and Copilot all run on your own accounts. 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 (your agents, 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.
