Releem

Releem is a database advisor tool designed for MySQL, MariaDB, and PostgreSQL. It focuses on analyzing database configurations and workloads around the clock to identify risks and improvement opportunities across three key dimensions: performance, reliability, and security. Unlike traditional monitoring tools that only display metrics and alerts, Releem provides a clear, prioritized list of actionable items. Each recommendation is accompanied by an explanation of why it matters and a step-by-step guide on how to implement the change safely. The tool integrates with a running database in minutes and requires no credit card to start. It continuously scans the database environment, detecting suboptimal settings such as incorrect buffer pool sizes, inefficient query cache configurations, missing indexes, unsafe authentication methods, or outdated TLS versions. For each detected issue, Releem assigns a severity level and a priority score based on impact and urgency, helping database administrators and DevOps teams focus on what matters most first. It also offers a safe application process: before applying any configuration change, Releem can simulate the impact, suggest the optimal new value, and verify the result after the change is made. This reduces the risk of downtime or performance degradation during tuning. In addition to configuration tuning, Releem can detect security vulnerabilities like weak passwords, exposed ports, or missing encryption settings. It also monitors reliability risks, such as replication lag, disk space shortages, or insufficient memory allocation for connections. The tool supports multiple database instances and can be used in cloud deployments, on-premises servers, or hybrid environments. Releem does not store sensitive data; it only reads metada
