Demo

1. Start in seconds

_{Install, run binex ui, and you're building workflows}

2. Build & run custom workflows

_{Drag & drop nodes, configure models, run with human input}

3. Explore & debug results

_{Debug, trace, diff, lineage — full post-mortem inspection}

What is Binex?

Binex is an open-source, fully local runtime for AI agent workflows. No cloud. No telemetry. No vendor lock-in.

pip install binex
binex ui

That's it. Browser opens. You're building AI workflows.

Why Binex?

• 100% local — your data never leaves your machine
• 100% open source — MIT licensed, audit every line
• Zero telemetry — no tracking, no analytics, no surprises
• Full debuggability — every input, output, prompt, and cost is visible
• Any model — OpenAI, Anthropic, Google, Ollama, OpenRouter, DeepSeek, and 40+ more via LiteLLM

Installation

Requires Python 3.11+

pip install binex

With extras:

pip install binex[langchain]    # LangChain Runnables
pip install binex[crewai]       # CrewAI Crews
pip install binex[autogen]      # AutoGen Teams
pip install binex[telemetry]    # OpenTelemetry tracing
pip install binex[rich]         # Rich colored CLI output

Web UI

Launch the visual workflow editor:

binex ui

Visual Drag & Drop Editor

_{Collapsible node sections, tool picker with 10 built-in tools, MCP config, Visual ↔ YAML sync}

6 node types: LLM Agent, Local Script, Human Input, Human Approve, Human Output, A2A Agent

• 20+ preset models including 8 free OpenRouter models
• Built-in prompt library (Planner, Researcher, Analyzer, Writer, Reviewer, Summarizer)
• Tool Picker — 10 built-in tools, MCP server integration, custom Python tools
• Collapsible sections — Model, Prompt, Tools, Advanced per LLM node
• Workflow Settings panel — configure MCP servers (stdio/HTTP) and cron schedules
• Switch between Visual and YAML modes — changes sync both ways (including tools & MCP)
• Real-time cost estimation as you build
• Custom model input — use any litellm-compatible model

Dashboard

_{All runs at a glance — status, cost, duration}

Debugging & Analysis

_{Left: Node-by-node debug inspection. Right: Gantt timeline with anomaly detection.}

Run Comparison

_{Side-by-side diff with filtering: changed, failed, cost delta}

19 Pages — Full CLI Parity

Category	Pages
Workflows	Browse, Visual Editor (with tool picker & MCP config), Scaffold Wizard
Runs	Dashboard, RunLive (SSE), RunDetail
Analysis	Debug (input/output artifacts), Trace (Gantt timeline), Diagnose (root-cause), Lineage (artifact graph)
Comparison	Diff (side-by-side with filter bar, compare with previous run), Bisect (NodeMap, DAG visualization, divergence metrics)
Costs	Cost Dashboard (charts), Budget Management
System	Doctor (health), Plugins, Gateway, Export, Scheduler (cron)

Navigation

Sidebar organized into 4 groups: Build (Editor, Scaffold), Runs (Dashboard), Analyze (Compare, Bisect), System (Gateway, Plugins, Doctor). Run-specific pages (Debug, Trace, Diagnose, Lineage, Costs) open from run context.

Replay

Debug any node → click Replay → swap the model or prompt → re-run just that node. No re-running the entire pipeline.

Quickstart

CLI

# Zero-config demo
binex hello

Tip: Runs a 2-node demo workflow (producer → consumer), no API keys needed.

# Run a workflow
binex run examples/simple.yaml

Tip: Uses your configured LLM provider. Set OPENAI_API_KEY or use ollama for fully local runs.

# Inspect the run
binex debug latest
binex trace latest

Tip: debug shows per-node inputs/outputs. trace shows the execution timeline as a Gantt chart.

Web UI

binex ui

Tip: Opens the browser automatically. Use --port 9000 to change the port, --no-browser to skip auto-open.

Create a Workflow

Pattern Nodes

9 built-in agentic patterns that expand into sub-DAG pipelines at runtime:

Pattern	Description
critic	draft → critique → refine (self-improvement loop)
debate	pro → con → judge (adversarial reasoning)
best_of_n	N parallel candidates → selector
reflexion	act → evaluate → reflect (iterative self-reflection)
scatter	mapper → N parallel workers → reducer (fan-out/fan-in)
fsm	finite state machine with configurable states and terminal
constitutional	draft → critique-per-principle → revise
chain_of_verification	draft → verify claims → synthesize
plan_execute	planner → N executors → aggregator

nodes:
  review:
    pattern: critic
    model: gpt-4o
    config:
      rounds: 2
    steps:
      critique:
        model: gpt-4o          # override per step
