@AniC_dev (boat.dev / Ascii, YC F26) published a YC Bookface warning: big sandbox vendors hand out large credits, then bills around $30k can imply ~50x markup vs bare metal. His team built long-running agent VMs for QA, PR review, docker compose, and Rust builds; boat.dev still takes 50–70% gross margin at about 6–19x below incumbents, and he says Claude Code can stand up an internal stack in an afternoon.

Key Takeaways

  • ✓Sandbox vendor choice is framed as a company-level decision alongside fundraising and hiring.
  • ✓Incumbent sandboxes fit short sessions, not hour-long cloud coding agents.
  • ✓Claimed 6–19x lower prices imply customers may overpay 15–68x vs raw compute.
