Open Source Ruby Database Software

Grafana OSS is the leading open-source platform for visualization and observability. It enables teams to query, visualize, alert on, and explore telemetry data from multiple sources in a single interface. With support for 100+ data source plugins—including Prometheus, Loki, Elasticsearch, InfluxDB, SQL/NoSQL databases, and OpenTelemetry—Grafana helps teams correlate metrics, logs, and traces across applications and infrastructure. Users can build interactive dashboards with rich visualizations, template variables, and reusable panels to monitor systems and troubleshoot issues in real time. Grafana includes capabilities such as ad hoc data exploration, alerting, annotations, and flexible query support. Its extensible plugin ecosystem integrates with cloud platforms, databases, and developer tools—allowing teams to build observability workflows without vendor lock-in. The easiest way to get started with Grafana is with Grafana Cloud, our fully managed, full-stack observability platform.

Logstash is a server-side data processing pipeline that dynamically ingests data from numerous sources, transforms it, and ships it to your favorite “stash” regardless of format or complexity. It supports and ingests data of all shapes, sizes and sources, dynamically transforms and prepares this data, and transports it to the output of your choice. Logstash is extensible, with over 200 plugins available to let you create and configure your pipeline how you choose.

Easily create living style guides/front-end style guides/pattern libraries by adding Markdown documentation to your Sass project. By clicking the color swatch in the style guide, users can copy the hex code of the color (useful for designers). When pointing the cursor on the variable name, it will be copied on click instead (useful for developers). The output will respect newlines. You can add any CSS to each example if it helps to make it better in the style guide only. You can set options to apply to all commands or all commands giving a name. This is useful when you depend on Haml or other templating engines. If you want your style guide to work as an API, you might have views already written somewhere else and don’t want to write the same HTML code into the style guide.

Blazer is a business-intelligence engine for Rails that lets teams write SQL in the browser, visualize the results, and share insights without leaving their app. It turns raw database queries into charts, tables, and dashboards, so non-engineers can explore data with minimal friction. Queries can accept parameters, enabling reusable reports for different time ranges, segments, or customers. Access controls and audit trails help teams manage who can run, edit, or view sensitive analyses. Scheduled checks and alerts turn BI into proactive monitoring by notifying you when metrics cross thresholds or regress. Because it’s a Rails engine, it integrates into your app’s authentication, layouts, and deployment workflows, reducing the overhead of maintaining a separate BI stack.

This is a recipe manager written in Ruby with MySQL database (rails) that allows easy sorting and searching using group tags. It will have integrated support for unit conversion and for the resizing of portions.

DataVision is a reporting tool similar to Crystal Reports. DV supports many data sources (JDBC, files) and many output formats (HTML, XML, PDF, LaTeX, Excel, delimited files, DocBook). DV includes a GUI editor. DV is embeddable. Reports are XML-based.

Delayed Job is a Ruby background-processing library designed to move long-running work out of the request cycle and into an asynchronous job queue. It was extracted from Shopify and is built around a database-backed jobs table rather than a separate queueing service. The system stores serialized Ruby objects that respond to a perform method, then workers pull and execute those jobs later. It supports priority, scheduled execution, retries, failure tracking, locking, and multiple workers across machines. Developers can enqueue explicit job objects or use send_later to delay method execution on existing objects. It is best suited for Rails and Ruby applications that need a simple, persistent background job system for emails, imports, downloads, indexing, and batch work.

ErosOnRails is a framework developed for cataloging works of art in cultural heritage institutions.

Evil Seed is a Ruby tool for seeding databases with realistic, localized, and structured test data. It integrates with Rails and uses Faker, but allows more advanced customization like data relationships and repeatable sequences.
