Vybin is a free, open desktop AI agent for vibe coders. Self-improving. Multi-model. Multi-tab. Local-first. No subscription, ever.
Vybin ships with a complete agent runtime, 8 model providers, 6 sandboxes, a multi-platform gateway, a cron scheduler, and ~30 built-in tools — all local, all free.
Skills auto-create and improve turn by turn. Lessons persist across sessions. A user-model learns who you are — your stack, projects, preferences, expertise.
Anthropic, OpenAI, Bedrock, Gemini, OpenRouter, Ollama (local), Groq, Mistral / DeepSeek / Together. Credential pool with automatic failover.
Run code in Local, Docker, SSH, Modal, Daytona, or Singularity. Isolation when you want it, speed when you don't.
Ctrl+T opens a new chat tab. Each one runs its own agent process, its own memory, its own skills. Like an IDE, but for conversations.
Drive your agent from Telegram, Discord, WebSocket or HTTP API (OpenAI-compatible). Your assistant, where you already are.
Schedule agents that run on their own. "Every Monday at 9, review the new PRs and send me a summary on Telegram." Done.
Browser (Playwright), voice (STT + TTS), vision + image gen, web search/extract/crawl, code execution, delegate, todo, checkpoints, skill manager, memory.
All your Model Context Protocol servers, plug-and-play. Vybin speaks MCP natively — no wrappers, no proxies, no fuss.
Tokens, costs, providers, latency. A dashboard that tells you exactly what you spent and where, without sending data anywhere.
No server in the middle. No subscription. Settings live in your
machine. Skills, lessons and user-model all stored under
~/.cero/. You own everything.
/new, /stop, /retry,
/undo, /personality, /compress,
/usage, /insights. Power-user shortcuts
built in.
Pixel fonts, scanlines, terminal palette. Three themes (violet, lima, amber). It's a tool that looks like fun to use.
A quick honest comparison. Other tools are great too — but if you're vibe coding, you probably want something that's free, local, and learns you.
No accounts. No setup wizard from hell. Drop in your API key (or point it at Ollama) and start.
Grab the .msi (Windows), .dmg (macOS) or .AppImage (Linux). Single binary, no Electron bloat.
Drop a key from Anthropic / OpenAI / OpenRouter, or aim it at your local Ollama. Switch any time.
Open a tab. Type what you want. Vybin learns your style, builds skills, remembers lessons. Every session you ship faster.
