2026 Software Stack Cost Index: Benchmark Report on SaaS Pricing, Seat Scaling & Self-Hosted TCO
An empirical benchmark study analyzing verified software licenses, per-seat scaling economics, open-source hosting TCO, and subscription overlap across 71 audited tools and 20 business capabilities.
Executive Summary & Key Findings
Satisfies CRM, Invoicing, Email, and Docs using verified permanent free allowances.
For 5-person agencies across 5 core capabilities ($147/mo total).
Hosting n8n, Twenty CRM, and Supabase on an $8/mo VPS vs $160+/mo commercial SaaS.
Modern business software costs vary dramatically based on license structure. Commercial vendors increasingly gate essential features behind $50–$90/seat tiers, while open-source self-hosted alternatives and modular SaaS stacks allow teams to operate at a fraction of standard industry pricing.

Runs Invoice Ninja, Plausible Analytics, or Uptime Kuma.
Runs n8n + Redis + PostgreSQL or Twenty CRM comfortably.
Multi-container cluster: Supabase + PostHog + Chatwoot + n8n.
