Koyeb remains committed to offering a free tier for deploying applications, despite challenges such as abuse and fraud that have led other platforms, like Heroku, to discontinue their free offerings. By running on bare metal infrastructure and implementing cost-efficient strategies like scale-to-zero, Koyeb aims to sustain its free tier without requiring credit cards for sign-up, although payment details may be needed if automated systems cannot verify user authenticity. The free tier serves as a key element of Koyeb's Product Led Growth strategy, allowing users to experiment with the platform, provide feedback, and potentially convert into paying customers as their projects grow. Koyeb offers a variety of plans alongside the free tier, including Hobby, Starter, Startup, and Enterprise options, to accommodate different user needs and encourage growth from hobby projects to full-scale business applications. The company also supports open-source projects within its free tier and encourages community engagement and feedback to enhance its platform further.
