MindsDB is an open-source AI layer that democratizes machine learning by embedding its capabilities directly within databases using familiar SQL syntax.
Introduction
For too long, integrating AI and machine learning into applications required complex data pipelines, specialized AI engineers, and moving sensitive data out of secure databases. MindsDB shatters this model. It provides a Federated Query Engine and a Cognitive Engine that sits between your data sources (like MySQL, Snowflake, or PostgreSQL) and your AI models (like OpenAI, LLama 2, or a custom predictor).
The result is a unified platform that allows any developer who knows SQL to perform sophisticated tasks, such as forecasting, churn prediction, or building an LLM-powered assistant, directly from their database. By eliminating data silos, providing a clear chain-of-thought for every AI answer, and ensuring data never leaves its trust boundary, MindsDB makes AI analytics trustworthy, real-time, and scalable.

Review
MindsDB is an innovative, open-source AI layer that democratizes machine learning by embedding its capabilities directly within databases using familiar SQL syntax. Co-founded by Jorge Torres and Adam Carrigan in 2017, its mission is to enable developers to build cutting-edge AI applications without the complexity of traditional data science infrastructure or cumbersome Extract-Transform-Load (ETL) pipelines.
The platform’s major breakthrough is the ability to “query-in-place,” eliminating data movement and ensuring real-time AI analytics. It allows users to create, train, and query predictive models or large language models (LLMs) on their data simply by running SQL CREATE MODEL and SELECT statements. With over $200$ data connectors, it unifies structured and unstructured data, enabling the creation of transparent, auditable AI assistants that provide real-time insights. MindsDB is a paradigm shift for operationalizing AI, making predictive analytics accessible to full-stack developers.
Features
AI-SQL Interface
Allows users to create, train, and query AI models using simple SQL statements like CREATE MODEL and SELECT FROM AI_TABLES.
Federated Query Engine
Connects to over $200$ data sources (databases, data warehouses, streaming platforms, and SaaS apps) and allows for real-time querying without moving the data (Zero-ETL).
Cognitive Engine & Knowledge Base
Unifies structured and unstructured data to build Retrieval-Augmented Generation (RAG) powered AI assistants that provide transparent, auditable reasoning for their answers.
Integrated LLMs and ML Frameworks
Acts as a broker, allowing developers to choose and integrate leading LLMs (like GPT-4) or ML frameworks and apply them to their connected data.
Multimodal Support
Supports training predictive models on various data types, including structured data, unstructured text, time-series data, and even images/documents.
Enterprise-Ready Deployment
Offers deployment options for VPC, on-premise, and serverless environments, ensuring data privacy, governance (RBAC), and high availability for large organizations.
Best Suited for
Full-Stack and Backend Developers
Ideal for developers who want to add predictive or generative AI features to their applications without becoming data science experts.
Data Engineers
To simplify the data pipeline, leverage the Federated Query Engine, and eliminate ETL processes for machine learning.
Business Analysts & Operations Managers
To generate complex, real-time analytics and predictive reports using natural language and simple SQL queries.
FinTech and E-commerce
Widely used for time-series forecasting, anomaly detection, churn prediction, and real-time recommendation systems.
Organizations with Data Governance Needs
Essential for enterprises that require explainability and full transparency (chain-of-thought) to validate AI results and maintain compliance.
Open Source Enthusiasts
The core platform is open source, attracting a large community of developers for local and individual projects.

Getting Started with MindsDB: Step by Step Guide
Getting started with MindsDB involves deploying the core platform and teaching it how to predict.
Step 1: Deploy the MindsDB Server
Deploy the open-source MindsDB container (via Docker or Helm charts) on your local machine, cloud server, or VPC.
Step 2: Connect to a Data Source
Use a CREATE DATABASE SQL statement to connect MindsDB to your existing data source (e.g., CREATE DATABASE my_postgres_db WITH ENGINE = ‘postgres’, PARAMETERS = {…};).
Step 3: Create an AI Predictor
Use a CREATE MODEL SQL statement to instruct MindsDB to train a machine learning model on your connected data for a specific prediction (e.g., CREATE MODEL my_model FROM my_postgres_db (SELECT * FROM sales_data) PREDICT sales_prediction;).
Step 4: Query the Predictor
Once the model is trained, use a simple SELECT statement to get real-time predictions, treating the model as an AI Table in your database (e.g., SELECT sales_prediction FROM my_model WHERE date = ‘2025-10-30’;).
Step 5: Operationalize in Application
Integrate the prediction query directly into your application code or business intelligence tool to leverage real-time AI insights for decision-making.
Frequently Asked Questions
Q: Is MindsDB fully open source?
A: Yes, the core MindsDB product is open source, allowing developers to use it for free for individual and local projects. Enterprise-level features (managed deployments, governance) are commercial.
Q: What is the "AI Table" concept?
A: The AI Table is a conceptual representation in MindsDB that allows developers to query a trained machine learning model as if it were a standard SQL table.
Q: Can MindsDB connect to SaaS apps like Salesforce or Slack?
A: Yes, MindsDB uses its Federated Query Engine and extensive connectors to integrate data from various SaaS applications, allowing that data to be used for model training and querying.
