Unofficial project. This wiki documents a community-built client that is not affiliated with, endorsed by, or supported by Mistral AI. The author has no connection to Mistral — the project simply builds on top of Mistral Vibe and the Mistral Vibe CLI. "Mistral" and "Mistral Vibe" are trademarks of Mistral AI.

Welcome to the Halny Vibe Deck wiki — the documentation for a desktop & web client of the Mistral Vibe AI coding agent.

Halny wraps the vibe-acp CLI in a full workspace: resumable agent sessions, file tree with preview and editing, a git panel, statistics, remote SSH projects, and a built-in HTTPS server for browser/mobile access.

What can it do?

• Chat with the agent — streaming responses, thinking, tool calls, colored diffs, plans (todo checklists), prompt queue, image attachments and @file mentions
• Resume anything — every session is persisted and can be replayed, with its own model/mode/thinking settings
• Preview & edit files — CodeMirror 6 editor with syntax highlighting, PDF/spreadsheet/docx/markdown/mermaid/image viewers, colored diffs
• Git integration — status, log, diff, stage/unstage, commit and push from the dock panel
• Remote SSH projects — run agent sessions on remote machines, browse and edit remote files over SSH
• Serve mode — built-in HTTPS server with login & password; use the UI from any browser or install it as a PWA on your phone
• Statistics — tokens, cache hit ratio and cost per model/session, all computed locally
• 6 languages — English, Polish, French, Spanish, German, Italian
