Leaving Heroku With Your Procfile Intact: 7 Migration Paths for a 5-Person Team

Migrating a small application from Heroku need not require a full rewrite because its Procfile, buildpacks, and configuration variables are generally portable, while add-ons, release-phase behavior, scheduled jobs, logging, and database migration require more deliberate work. Dokku, Railway, and Fly.io offer the closest path for retaining Procfile and buildpack workflows, whereas Render, DigitalOcean App Platform, Northflank, and Qovery typically require a Dockerfile or prebuilt container image, with each Procfile process becoming an independently configured service. The article recommends exporting configuration variables early, explicitly recreating release migrations and operational integrations, testing for memory leaks that Heroku’s regular dyno restarts may have concealed, and keeping Heroku available during a staged DNS cutover. Costs for a web process, worker, and roughly 10 GB PostgreSQL database vary substantially: self-hosted Dokku is cheapest in direct spending but shifts server maintenance to the team, managed PaaS options reduce operations work, and Qovery becomes more economical chiefly at larger scale or when organizations benefit from using their own cloud accounts and committed-use discounts. A short Dockerfile or an OCI image produced with Cloud Native Buildpacks can improve portability across future platforms, while the preferred destination ultimately depends on whether the team prioritizes minimal migration changes, managed convenience, low infrastructure costs, multi-region deployment, or control of its own cloud environment.
