Looking for a managed PostgreSQL database with a free tier? We've got you covered. In this article, we'll explore the top PostgreSQL databases with free tiers to use for your applications in 2025. These free-tier options are perfect for side projects, MVPs, and learning how to use cloud databases. All these database solutions integrate with Koyeb, enabling you to seamlessly connect databases hosted by third-party providers to your applications running on the Koyeb platform.

In today’s fast-evolving tech world, seamless connectivity between applications and databases is critical, but often comes with challenges such as credential management and environment-specific configurations. Choreo simplifies this process by offering streamlined connection options to Choreo-managed databases, making it easy to integrate components with databases. We’re excited to announce our latest feature: database connections.

Discover how to efficiently mask SQL data at scale. Explore the best practices based on our extensive experience with large enterprises. Almost every enterprise has SQL databases, which means they need SQL data masking. Some SQL databases have built-in masking options, such as Microsoft SQL Server dynamic data masking. But is that the right approach? And what about all of your other databases and data sources?

Databases are the backbone of modern applications, enabling efficient storage and retrieval of data. But have you ever wondered why databases like PostgreSQL don’t simply use HTTP for communication? The answer lies in the specialized nature of database protocols. The PostgreSQL wire protocol is specifically designed to handle complex database tasks such as transactions, secure authentication, and efficient data transfer.

There is increasing demand for realtime data delivery as users expect faster experiences and instantaneous transactions. This means not only is lower latency required per message, but providers must also handle far greater capacity in a more globally-distributed way.

SQL Server is a cornerstone RDBMS for enterprise applications, handling transactional workloads, analytics, and complex querying. As modern architectures increasingly rely on APIs for data access—particularly in microservices, cloud-native systems, and third-party integrations—efficient exposure of SQL Server data has become essential. API wrappers simplify this process by automating the creation of RESTful endpoints for SQL Server, reducing the need for custom API development.

Following the deprecation of Realm, we have partnered with MongoDB to ensure that MongoDB customers can continue to deliver the device sync capabilities their customers depend on. The solution: a MongoDB Connector for the Ably LiveSync product. Ably LiveSync enables you to seamlessly fan-out your MongoDB Atlas state to billions of clients in realtime - ensuring reliable, low-latency delivery of your document data.

As a data engineer who has worked on building and managing various technical aspects of data pipelines over the years, I've navigated the intricate landscape of data integration, transformation, and analysis. In mid-market companies, where data-driven decision-making is pivotal, constructing efficient and reliable database pipelines allows you to store data in cloud data warehouses and carry out better data analysis or machine learning models.

Today, Confluent, the data streaming pioneer, is excited to announce its entrance into MongoDB’s new AI Applications Program (MAAP). MAAP is designed to help organizations rapidly build and deploy modern generative AI (GenAI) applications at enterprise scale.
