# Heroku Canonical: https://inetgeek.com/hosting/heroku/ Managed application platform that runs apps in containers called dynos, deployed from Git or Docker images, with add-on services such as Heroku Postgres. ## Who it suits Teams that want to deploy by pushing to Git and let the platform handle the runtime, with Postgres, a scheduler and Docker deploys available on the same platform. Consider something else if The dyno filesystem is ephemeral, and a web process must respond within 30 seconds of receiving a request. ## Adoption signals - Detected running on 15,978 live sites (BuiltWith, checked 2026-09-12) ## iScore 64 / 100 (80% interval 61–68), rank 11 of 11 in hosting — interval overlaps the next rank, so this is an ordering, not a finding. inetGeek's own reading, computed from sourced facts against category peers by disclosed rules. Not a provider claim. Intervals are 80%; a provider with few documented facts is pulled toward the category middle rather than scored on what little is known. Method: https://inetgeek.com/iscore/.
