Why developers switch from ShipEngine
Expensive at every tier
ShipEngine Advanced starts at $75/mo for just 1,000 labels. RevAddress Starter is $29/mo for 5,000 API requests. At 10,000/mo: ShipEngine = $600, RevAddress = $79. That's 87% less.
Overage fees add up quietly
Exceed your ShipEngine plan and you pay $0.06–$0.075 per extra label with no cap. RevAddress returns a clean 429 — no surprise charges, ever. Upgrade when you're ready.
No free tier for own-carrier
ShipEngine's free tier only works with their carrier accounts. Bring your own USPS account? You need Advanced ($75+/mo). RevAddress free tier works with your own USPS credentials from day one.
