Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Plivo

  • The headline per-message saving does not apply to US 10DLC registration fees or carrier surcharges, which are pass-through costs and identical across vendors.
  • The feature surface is narrower than the market leader, so products needing video, email or richer verification will need a second supplier.
  • Support is tiered and the entry tier is not appropriate for traffic that a business depends on commercially.
  • Deliverability on some international routes depends on an underlying carrier mix that can change without the customer being informed.
  • Its price advantage is smaller on US A2P traffic than on international routes, so a US-only sender may save considerably less than a headline comparison suggested.

Postman

  • Free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans
  • Only 25 collection runs per month and 1,000 API calls/month on free tier
  • Removed local-only Scratch Pad mode in 2023, forcing cloud account creation and sync
  • Requires Postman account and internet connection for most features
  • Cloud-first architecture with mandatory syncing to Postman's cloud servers
  • No CI/CD integration or advanced security features on free plan

Answered from the vendors’ own pages

Plivo: Will switching to Plivo cut our US messaging bill?

Partly. The per-message rate may fall, but 10DLC brand and campaign fees and the per-segment carrier surcharges are pass-through costs that are the same whichever provider you use.

Postman: What is the cost of Postman?

Postman has a free plan limited to 1 user, 25 collection runs/month, 1,000 API calls/month. Team plans start at $14/user/month for Basic. Professional at $29/user/month, and Enterprise at $49/user/month.

Plivo: Does Plivo publish pricing?

Yes, as a per-destination rate card covering SMS and voice by country, so you can model your own destination mix before contacting sales.

Postman: Can I use Postman offline?

Postman requires an internet connection to sync collections to the cloud. Since 2023, the Scratch Pad local-only mode was removed. Users must sign in with a Postman account, and collections sync to cloud by default. Offline work is possible but limited without cloud sync features.
