Opened #TropicalOnRails with a simple truth: new startups are choosing Rails in 2025—and thriving with it. Why, how, and what can we do better?
But first, a quote from @gxespino from @luthorAI
These are all the founders I talked to this time: Rails lets them focus on business, not boilerplate 🙌
The Rails ecosystem is vibrant, but founders want more:
⚡️Modern, cohesive frontend tools: advanced Hotwire and Inertia docs, design-forward UI kits
⚡️AI tooling and guidance includes patters of integration with Python services, infrastructure and tooling for Agents, MCPs and more.
⚡️Prescriptive guidance for performance at scale and working with LLMs in production
⚡️New reason to be vocal about using Ruby: Pragmatic Enlightenment. More about it >>
