10 Best Free Alternatives to Heroku (2026)
Heroku pioneered the PaaS model with git-push deployments, but its elimination of the free tier in 2022, high dyno pricing ($7/month for basic), and limited compute regions have sent developers looking for alternatives. Modern platforms like Railway and Fly.io offer generous free tiers, faster deployments, and global edge compute at competitive prices.
