Reviewers describe Heroku in narrow but clear terms: it makes it easy to deploy software quickly and supports plenty of integrations, which stands out as the main practical benefit. The only specific drawback mentioned is that it no longer offers a free tier. Founder reviews are present, but they contain no written feedback, so they do not add evidence beyond generally positive sentiment. Overall, the review text points to a developer-friendly deployment experience, with cost now a more noticeable concern for smaller or casual users.
