Cost Scale Analysis: When to choose Postman over Railway
Both Postman and Railway rely on identical usage-based scaling curves in this simulator. At equivalent workloads (free tier up to 7,500 MAUs, followed by $23 base + $0.007 per additional active user), their price trajectories align exactly, meaning the commercial decision pivots strictly on technical fit and compliance footprint.
Notably, Postman supports a broader compliance footprint (SOC2, GDPR) compared to Railway (None), representing a critical differentiator for security audits.
