Stop Paying for Token Bloat.
Start Executing Locally.

Agent loops re-send your whole conversation on every turn, and the bill grows with the length of the task. Vibe Engine compiles your intent into a recipe once, then the model steps back. A recipe with no ai_call step reruns with no model involved at all — no tokens, no cloud dependency, no vendor lock-in.

Why Is My AI Tool Using So Many Tokens?

The Agent Loop Problem

Cursor / Windsurf / Copilot / Claude Code

  • Every interaction re-sends your entire conversation history
  • Agent loops retry, backtrack, and re-read files — each step costs tokens
  • A trivial "write a file to my desktop" task costs a full conversation of context
  • Monthly costs scale with usage, and heavy months are the expensive ones
  • No way to "save" a working interaction and replay it for free
The Vibe Engine Way

Compile Once, Execute Forever

  • AI writes a small recipe once — that's the only LLM call
  • Executes locally — and if the recipe has no ai_call step, every rerun costs zero tokens
  • Same recipe, same result, every time — deterministic execution
  • $8.99/month flat — run unlimited recipes, no per-token billing
  • Save recipes as JSON files — share them, git-commit them, cron-schedule them

Locked Into One AI Provider? There's a Better Way.

The Lock-In Trap

Cloud AI IDE Extensions

  • Each tool ties your workflow to its own app and service
  • Copilot requires GitHub + Microsoft ecosystem
  • Windsurf ties workflows to their cloud
  • Switch providers = rebuild everything from scratch
  • Provider goes down = you can't work
Model-Agnostic Freedom

Vibe Engine Works With Everything

  • Ollama, LM Studio, OpenAI, Anthropic, Gemini, Groq, OpenRouter — all supported
  • Auto-discovers local AI servers on startup — zero configuration
  • Same recipe works across any OpenAI-compatible endpoint
  • Switch models mid-workflow — local for privacy, cloud for power
  • Runs offline with local models — no internet required

Is My Code Being Sent to the Cloud?

The Privacy Problem

Cloud-First AI Tools

  • Your code, prompts, and files are sent to remote servers for processing
  • Even "local" modes often phone home for telemetry or model calls
  • No way to guarantee sensitive data stays on your machine
  • Hard to use on a network with no internet access
Local Execution

Your Data Never Leaves Your Machine

  • Standalone binary — no cloud dependency, no telemetry
  • Encrypted secrets vault — API keys never appear in recipe files
  • Use local models (Ollama, LM Studio) for zero-cloud workflows
  • SHA-256 audit receipts prove exactly what executed and when
  • Air-gap ready — works on networks with no internet access

Why Do AI Agent Frameworks Keep Failing?

Framework Fatigue

LangChain / CrewAI / AutoGPT

  • Python dependencies, virtual environments, version conflicts
  • Agent loops hallucinate, retry endlessly, or silently fail
  • Context windows overflow after a few steps — small models can't cope
  • Requires developer expertise to set up and debug
  • Every run is non-deterministic — same input, different output
No Frameworks. No Dependencies.

One Binary. One JSON File. Done.

  • Zero dependencies — download vibra.exe, double-click, working
  • Self-healing JSON parser makes even 3B local models produce reliable recipes
  • No agent loops — single-pass compilation eliminates context overflow
  • Deterministic execution — the same recipe runs the same way every time
  • Auto-repairs truncated output, markdown fences, and unbalanced braces

Can Small Local Models Actually Do Real Work?

The Small Model Problem

Using Ollama or LM Studio Alone

  • Small models (3B-7B) produce broken JSON and incomplete outputs
  • No execution layer — the model generates text but can't act on it
  • No file operations, no HTTP requests, no system automation
  • Multi-step workflows require manual copy-paste between prompts
  • No way to chain local model output to a cloud model and back
Small Models + Vibe Engine = Full Automation

The Execution Layer Local Models Were Missing

  • RepairTruncatedJSON fixes broken output from small models automatically
  • Ships vibra-llama — a custom Ollama model tuned for deterministic recipes
  • Auto-discovers Ollama, LM Studio, vLLM, Jan, LocalAI on startup
  • Chain local models to cloud models in the same workflow (privacy sandwich)
  • 7 action types: file ops, HTTP, scripts, AI calls, notifications, transforms, GUI automation

Frequently Asked Questions

How does Vibe Engine cut token usage?

Traditional agent loops re-send your entire conversation history on every interaction, so cost scales with how long the task runs. Vibe Engine takes a different approach: the AI writes a small JSON recipe once, then steps back, and the Go runtime executes it locally. There are two kinds of recipe and they behave differently. A pure-execution recipe — one with no ai_call step — reruns with no model involved at all, so reruns cost nothing. A recipe that contains an ai_call step still calls a model each run; it is cheaper than an agent loop because it sends one structured turn instead of a growing transcript, but it is not free.

Does Vibe Engine work with Ollama and LM Studio?

Yes. Vibe Engine auto-discovers local AI servers on startup, including Ollama (port 11434), LM Studio (port 1234), vLLM (port 8000), Jan (port 1337), and LocalAI (port 8080). No configuration needed — just have your local model server running and Vibe Engine connects automatically. It also ships vibra-llama, a custom Ollama model tuned for deterministic recipe generation with even small 3B parameter models.

Is Vibe Engine an alternative to Cursor or GitHub Copilot?

Vibe Engine solves a different (and broader) problem. Cursor and Copilot are code-completion tools tied to specific editors and cloud providers. Vibe Engine is a general-purpose local execution engine that works with any AI model, any MCP client (Claude Desktop, Cursor, Cline, Windsurf, VS Code), and automates tasks beyond just code — file operations, HTTP requests, system scripts, GUI automation, and multi-model AI pipelines. Think of it as the Unix pipe for AI: the model is your grep, Vibe Engine is your shell.

Can I use Vibe Engine without any cloud AI at all?

Absolutely. With a local model running through Ollama or LM Studio, Vibe Engine operates with zero internet connectivity. Your data never leaves your machine. This makes it suitable for networks with no internet access, and any situation where sending code or data to external servers is not an option.

Why do AI agent frameworks like LangChain and CrewAI keep failing?

Agent frameworks use ReAct-style loops where the AI repeatedly reasons, acts, observes, and re-plans. Each loop iteration adds to the context window, and small models (3B-7B) quickly lose coherence as context grows. The result: hallucinated actions, infinite retry loops, and connection errors. Vibe Engine eliminates this by compiling the entire workflow into a single-pass recipe upfront. There's no loop to overflow, no accumulated context to corrupt, and no non-deterministic re-planning.

How do Vibe Engine recipes work with MCP (Model Context Protocol)?

Vibe Engine runs as an MCP server that any compatible client can call. When you use Claude Desktop, Cursor, Cline, or Windsurf, those tools can invoke Vibe Engine as a tool provider via MCP's stdio protocol. The two exposed tools are run_recipe (execute a workflow) and validate_recipe (check a recipe before running). This means any AI assistant that supports MCP can drive Vibe Engine's local execution capabilities without needing to understand the recipe format itself.
