Price notes and sources
  1. Each vendor's public list price in US dollars, before tax, for the selected configurations, checked 7 November 2026. Prices change, so check the source before you decide.
  2. The machines differ. An offstage sandbox is one of up to 8 on a Mac Studio M5 Max, sharing its 18-core CPU and 36 GB of memory. CPU and memory are not reserved per sandbox. GitHub's standard runner has 3 M1 cores; Blacksmith's selected M4 runner has 6 vCPUs; Namespace's selected macOS runner has 4 vCPUs and 7 GB RAM. Scaleway, AWS and Daytona rent whole M4 or M4 Pro Mac minis.
  3. GitHub's $0.062/minute, Blacksmith's $0.08/minute and Namespace's prepaid $0.04/minute are multiplied by 60 for the hourly bars. Namespace's overage rate is $0.06/minute ($3.60/hour). Included minutes may cover some work. GitHub rounds each job up to a whole minute; offstage bills per second.
  4. Daytona's $60.08 reservation can't end early and holds up to 2 sandboxes on one Mac. AWS and Scaleway charge the first 24 hours, then by usage. Scaleway's €0.22 an hour is converted at the European Central Bank's rate of 6 November 2026 (€1 = $1.1165).
