FastRuby.io

FastRuby.io is the upgrade service of OmbuLabs, which lists a Philadelphia, Pennsylvania address on its site; its team page shows engineers in the United States, Brazil, Argentina and South Africa. Its service page offers Ruby and Rails upgrades and an application-specific roadmap estimating effort per minor version jump, alongside maintenance, security audit and staff augmentation services. The "100+ upgrade projects" and "30,000 developer hours" figures on that page are FastRuby's own.

The Procore upgrade account, published June 12, 2020, describes OmbuLabs working with Procore on Rails 5.0-to-5.1 upgrade issues. The Irish Chess Union account, published September 14, 2026, describes a Rails 7.0-to-8.1 upgrade of a volunteer-run association's application. Both include a named client quote but remain supplier-hosted evidence.
