Fly.io vs Koyeb

Fly.io suits developers prioritizing pure usage-based edge compute, while Koyeb offers a freemium full-stack PaaS with structured fixed-fee plans.

Our Take

Both Fly.io and Koyeb offer container-native deployment on a global edge network with a free tier, and neither supports self-hosting. The primary distinction between these two platforms lies in their pricing models and the breadth of their service offerings. Fly.io operates on a pure usage-based model, allowing developers to pay only for the resources consumed, which can be ideal for highly variable or bursty workloads where cost efficiency is paramount. Its explicit focus on edge compute is designed for applications demanding minimal latency and global distribution. Koyeb, conversely, employs a freemium model, providing a free tier before transitioning into structured paid plans like Pro, Scale, and Enterprise, which include fixed monthly fees in addition to compute costs. This approach caters to teams that prefer predictable budgeting and a clear path for scaling with defined tiers. Koyeb positions itself as a full-stack PaaS, aiming to simplify the entire deployment and management lifecycle beyond just container orchestration. Developers prioritizing fine-grained cost control and a dedicated edge compute environment will find Fly.io to be the more suitable choice. Teams seeking a comprehensive full-stack PaaS with a freemium entry point and structured, predictable monthly plans should opt for Koyeb.
