Why KloudUtils

Your data stays on your computer

No account. Your work stays local: notes, secrets and files stay where they are.

Plain files you own

Notes are Markdown and requests are .http files. Sync them, put them in git, or open them elsewhere.

No more pasting secrets into websites

Decode a token, format a payload or compare a config without sending it anywhere.

Works offline

Works on a plane, without internet: write notes with diagrams and improve them with AI.

Yes. KloudUtils runs an MCP server on your computer, so Claude, Codex, Cursor, VS Code and other AI agents can query your data files, read notes, check certificates or send saved API requests. The kloudutils CLI gives commands your secrets without showing them.

Changes, and a secret sent to a new host, wait for your approval in the app. The app fills in secret values itself, so the AI doesn’t see them.

Your local toolbox for daily work
