Best Self-Hosted Databases for Companies

In a world where data powers every business decision, maintaining privacy, flexibility, and control has become more important than ever. That’s why an increasing number of companies are moving away from cloud-only tools and embracing self-hosted databases — systems they can install, manage, and control entirely on their own infrastructure.

But what exactly does self-hosted mean, and why are so many modern teams choosing this model?

What Does Self-Hosted Mean and Why It Matters

A self-hosted database is a system you install and operate on your own server, either on-premises or in a private cloud. Unlike SaaS (Software as a Service) platforms that rely on third-party infrastructure, self-hosted setups allow you to have local control over your data, configurations, and security protocols.

This autonomy is crucial for organizations that handle sensitive information or operate in industries with strict compliance regulations. With full access to the source code, businesses can audit, customize, and optimize their databases for unique workflows.

For example, a team building home automation or home assistant integrations may prefer to store and process data locally rather than sending it to the cloud. This ensures faster response times and greater privacy — something cloud-based systems can’t always guarantee.

The rise of open source software has made self-hosting more accessible than ever. Companies no longer need extensive IT teams to deploy powerful database systems. Instead, they can use flexible, intuitive platforms like Baserow, which simplify setup and management while retaining full data control.

Top Self-Hosted Databases for Companies

Baserow – The Modern, No-Code Open Source Database

Baserow is redefining how companies approach data management. As a no-code, open source software, it empowers teams to build and scale internal tools, manage projects, and centralize operations — all while maintaining complete ownership of their data.

Organizations can host Baserow on their own servers or private clouds, giving them complete control over uptime, access, and performance. Its accessible source code lets teams customize fields, workflows, and automation rules to match their internal processes.

Baserow integrates seamlessly with tools like Home Assistant or IoT ecosystems for home automation, making it a great choice for tech-driven businesses looking to unify local and digital operations.

What truly sets Baserow apart is its community-driven development. The Baserow Community actively contributes templates, integrations, and plugins that continuously enhance the platform. This collaborative environment ensures rapid evolution and transparent improvements.

Example Use Case: A logistics company uses Baserow as its internal database to manage delivery routes and warehouse stock. Hosting it on its private server ensures fast access for staff and full compliance with internal data protection policies.

PostgreSQL – Reliable and Scalable

PostgreSQL is a battle-tested open-source relational database known for data accuracy and scalability. It’s widely used in industries that demand consistent performance and complex querying capabilities.

Companies appreciate PostgreSQL for its community support and rich extensions ecosystem. It’s also a top choice for developers looking to integrate structured data systems with no-code tools like Baserow. Learn more about databases and structure in Baserow’s database blog.

MySQL / MariaDB – Proven and High-Performance

MySQL and MariaDB remain two of the most popular self-hosted database options for web and enterprise applications. Both are efficient, stable, and highly customizable.

They give developers source code access for performance tuning and flexibility in configuration — essential for applications that rely on real-time analytics or high-speed transactions.

MongoDB (Community Edition) – Flexible and Document-Based

MongoDB’s community edition is a favorite for companies managing unstructured or semi-structured data. Its document-based approach offers flexibility, and self-hosting ensures sensitive data stays within the organization’s ecosystem.

It’s especially useful for startups developing AI models or automation systems that depend on local computation and self-hosted AI environments.

Benefits of Choosing a Self-Hosted Database
