The same four-service stack costs $69/month on both Sevalla and Railway — until workloads turn bursty or spiky. A worked three-scenario comparison with the math, plus the flat-rate Hetzner number that collapses both bills.
Tabby Is the Self-Hosted Copilot Nobody Priced Yet: Owned GPUs vs Per-Seat Copilot
Fifty developers on Copilot Business costs $11,400 a year; a $3,000 GPU box serves the same team flat. The full TCO of self-hosted Tabby on owned GPUs — hardware, power, ops time, and Copilot's usage-based overage — with breakevens at 10, 20, and 50 seats.
