Open Source Ruby Database Software for Mac

Grafana OSS is a leading open-source visualization and observability platform that lets you query, visualize, alert on, and explore your data—regardless of where it’s stored. With support for 100+ data source plugins (such as Prometheus, Loki, Elasticsearch, InfluxDB, SQL/NoSQL databases, OTel, and more), you can unify metrics, logs, traces, and other observability signals in one place. Grafana OSS empowers you to build dynamic, reusable dashboards with rich visualizations, template variables, interactive filtering, and cross-panel linking. Its Explore mode enables ad-hoc queries and side-by-side comparisons of time ranges, queries, and data sources. Grafana also includes built-in alerting, allowing you to define threshold-based rules and send notifications to external systems (e.g. Slack, PagerDuty, OpsGenie). Backed by a strong community (https://grafana.com/community/) and open governance, Grafana OSS is free to use, modify, and deploy under the AGPL-3.0 license.

Redland is a set of object-based, modular and portable C RDF libraries providing RDF APIs for the graph, triple storage (librdf), RDF/XML parsing and serializing (Raptor), SPARQL RDF querying (Rasqal). Language APIs in Perl, PHP, Python, Ruby and others.

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.

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. It’s ideal for developers who need high-quality sample data for testing or demos.

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.

Logidze is a Ruby on Rails extension that enables versioning for ActiveRecord models using PostgreSQL JSONB columns. It stores change history directly in the database, allowing applications to track, view, and restore previous states of a record without creating additional tables.
