Which one is for you

Pick Fly.io if

  • Fits if you want machines near users in several regions and are fine on the command line
  • Works for apps that stop when idle and pay by the second

Look elsewhere if

  • Skip it if you want a free plan, as the trial is $1 for 7 days
  • Not for you if you don't like a command line
  • Pricey if you add a database: Managed Postgres starts at $38 a month
  • Watch out: the prices quoted are for Ashburn and Secaucus, the cheapest regions, and a dedicated IPv4 is $2 a month
  • Watch out: data out costs $0.02 per GB in North America and Europe and $0.12 in Africa and India

Pick Koyeb if

  • Fits if you deploy containers and want autoscaling
  • Works for AI jobs that need GPUs and per-second billing

Look elsewhere if

  • Skip it if you want a free plan
  • Pricey if you run one small app, at $29 plus compute
  • Watch out: the pricing page says Koyeb is joining Mistral AI and doesn't say what changes
  • Watch out: private Slack support, SSO and RBAC are on higher plans, and the SLA starts at Scale, $299

How this page was made

  • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
  • The grades are our own, from each tool’s review or report card. The GPA is their average.
  • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
  • The differences and the answers to the questions are worked out from those listings.
