Ranburg developer tools are built for software engineers, Salesforce admins, and technical teams who need reliable utilities without installing desktop apps. From JSON and SQL formatters to regex testers, UUID generators, and Salesforce-specific builders, every tool delivers instant feedback in a clean interface optimized for daily development work.

Privacy matters: the majority of our developer utilities run client-side using modern browser APIs. Your source code, queries, and test data are not uploaded to Ranburg servers. This makes our tools safe for prototyping with sample data and debugging production-like payloads in sandbox environments.

The collection spans general-purpose utilities and Salesforce-specialized generators including SOQL builders, Apex test scaffolds, cron expression generators, and OmniStudio expression helpers. Whether you are a full-stack developer, DevOps engineer, or Salesforce consultant, you will find tools that save hours of repetitive formatting and boilerplate writing.

All tools are responsive, keyboard-friendly where applicable, and include SEO-rich documentation below each utility so you can learn while you work. Explore calculators and generators categories for related utilities, or use the site-wide search to jump directly to any tool.
