ToolJet AI vs n8n Self-Hosted AI Starter Kit: Feature Comparison, Docker Setup, and $5 VPS Cost Breakdown

Introduction#

Self-hosted AI platforms are gaining traction among developers and sysadmins who want control over their AI workflows without vendor lock-in. Two notable open-source options are ToolJet AI and n8n's self-hosted AI starter kit. Both offer ways to build AI-powered applications, but they differ significantly in approach, features, and deployment.

This post compares these platforms side-by-side, focusing on:

• Core features and capabilities
• Docker-Compose setup on a $5 VPS
• Local LLM integration (Ollama/LM Studio)
• Security considerations
• Total cost of ownership

Whether you're a developer evaluating tools for a project, a sysadmin setting up AI infrastructure, or a hobbyist running experiments on a budget, this comparison will help you choose the right platform.

Overview of ToolJet AI and n8n AI Starter Kit#

ToolJet AI#

ToolJet AI is part of the broader ToolJet platform, which allows users to build internal tools with drag-and-drop components. The AI component enables integration with large language models (LLMs) and other AI services, allowing developers to create AI-enhanced dashboards and workflows.

Key features include:

• Visual builder for dashboards and forms
• Pre-built AI components (chat UI, prompt templates)
• Integration with OpenAI, Hugging Face, and local LLMs
• REST API and database connectors
• Multi-user collaboration and role-based access

n8n AI Starter Kit#

n8n is a workflow automation platform, and its AI starter kit is designed for developers who want to build AI-powered workflows. It includes pre-configured nodes for common AI tasks and integrates with various LLM providers.

Key features include:

• Workflow-based approach to AI tasks
• Pre-built nodes for text generation, classification, and more
• Integration with OpenAI, Anthropic, and local LLMs
• Extensible node system
• Docker-based deployment

Feature Comparison#

Docker-Compose Setup on a $5 VPS#

Both platforms can run on a $5 VPS (like DigitalOcean's Basic plan or Vultr's Starter instance), but resource allocation and performance will vary.

Prerequisites#

• VPS with at least 1GB RAM (2GB recommended)
• Docker and Docker Compose installed
• Domain name (optional but recommended for HTTPS)

ToolJet AI Setup#

1. Clone the repository:

git clone https://github.com/ToolJet/ToolJet.git
cd ToolJet

2. Create a .env file with basic configuration:

cp .env.example .env

3. Edit .env to set:

TOOLJET_HOST=https://yourdomain.com
LOCKBOX_MASTER_KEY=generate_a_secure_key
SECRET_KEY_BASE=generate_a_secure_key

4. Start services:

docker-compose up -d

5. Initialize the database:

docker-compose run --rm tooljet-server npm run db:reset

n8n AI Starter Kit Setup#

1. Clone the repository:

git clone https://github.com/n8n-io/self-hosted-ai-starter-kit.git
cd self-hosted-ai-starter-kit

2. Start services:

docker-compose up -d

3. Access the web interface at http://your-vps-ip:5678

Local LLM Integration#

Both platforms support integration with local LLMs through Ollama and LM Studio.

Ollama Integration#

1. Install Ollama on your VPS:

curl https://ollama.ai/install.sh | sh

2. Pull a model:

ollama pull llama2

3. Start Ollama service:

ollama serve

4. In ToolJet AI:

   • Add a new REST API data source
   • Point to http://localhost:11434/api/generate
   • Use appropriate request body format

5. In n8n:

   • Use the HTTP Request node
   • Configure to POST to http://localhost:11434/api/generate
   • Set JSON body with model and prompt

LM Studio Integration#

LM Studio runs locally on your development machine. To integrate with a remote VPS:

1. Start LM Studio and enable local server
2. Configure reverse proxy (nginx) on VPS to forward requests to your local machine
3. Update platform configurations to use the reverse proxy endpoint

Performance on $5 VPS#

Running either platform on a $5 VPS (1 vCPU, 1GB RAM) is possible but comes with limitations:

ToolJet AI#

• Initial load time: 15-30 seconds
• Memory usage: ~600MB with basic setup
• Concurrent users: 2-3 before performance degradation
• Database queries may slow down with complex dashboards

n8n AI Starter Kit#

• Initial load time: 10-20 seconds
• Memory usage: ~400MB
• Workflow execution: Good for simple workflows
• Complex AI tasks may timeout or fail

Security Hardening#

ToolJet AI Security Considerations#

1. Environment Variables: Never commit .env files to version control
2. HTTPS: Use Let's Encrypt with nginx reverse proxy
3. Database: Secure PostgreSQL with strong passwords
4. API Access: Implement rate limiting and authentication
5. Updates: Regularly pull latest Docker images

n8n AI Starter Kit Security Considerations#

1. Webhook Security: Use webhook validation and authentication
2. Credentials: Store sensitive data in n8n's credential manager
3. Network: Restrict access to necessary ports only
4. Execution: Monitor workflow execution for unusual activity
5. Updates: Keep n8n Docker image updated

Cost Analysis#

Monthly Costs (USD)#

Both platforms have similar cost structures. The main variable is whether you need a dedicated domain and backup storage.

FAQ#

1. Can both platforms run on the same VPS?#

Yes, but you'll need to manage resource allocation carefully. Running both simultaneously on a 1GB VPS may cause performance issues.

2. Which platform has better local LLM support?#

Both platforms support local LLMs equally well. The choice depends more on your workflow preferences than LLM integration capabilities.

3. How do updates work for each platform?#

ToolJet AI requires pulling new Docker images and running database migrations. n8n updates are simpler, usually just requiring a new Docker image pull.

4. Can I migrate workflows between platforms?#

Direct migration isn't possible due to different architectures. You'll need to rebuild workflows in the target platform.

5. Which platform is better for beginners?#

ToolJet AI's visual builder makes it more approachable for beginners, while n8n's JSON-based workflows require more technical knowledge.

Conclusion#

Both ToolJet AI and n8n's self-hosted AI starter kit offer compelling options for developers and sysadmins looking to deploy AI capabilities on a budget.
