The short version

  • Only Cerebrium has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cerebrium free Hobby tier limited to 3 apps and 5 GPU concurrency; Koyeb pricing starts at $29/month with additional compute costs
  • They diverge on capability: Cerebrium covers Ultra-fast cold starts, Koyeb covers Serverless containers.
  • Prices and features above were last checked on 29 August 2026.
