Self-host vs Terraform

Example values: replace every number with your own. None of them is vendor data.

Self-hosting saves about $780 a year for 20 seats: SaaS $2,400 vs self-host $1,620 (server $144, backups $36, admin time $1,440). Break-even at about 14 seats at these numbers.

Admin hours start from our guess for difficulty unrated and are yours to edit. Terraform price: No per-seat price (Essentials). HCP Terraform is usage-based (resources under management), no per-seat price: Free up to 500 managed resources; Essentials $0.10/resource/mo; Standard $0.47/resource/mo; Premium $0.99/resource/mo. Corroborated from third-party reads. Source: vendor pricing page, checked 2026-11-10.
