  • Only Postman has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bandwidth commercial terms are negotiated contracts rather than a published rate, so a small team cannot start without going through a sales process.; Postman free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans
  • They diverge on capability: Bandwidth covers Owned US carrier network, Postman covers API client.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Bandwidth

  • Commercial terms are negotiated contracts rather than a published rate, so a small team cannot start without going through a sales process.
  • US A2P messaging still requires 10DLC brand and campaign registration, and those fees plus per-segment carrier surcharges are charged on top of the negotiated message rate.
  • The self-serve developer experience is weaker than the aggregators it competes with, so teams prototyping quickly start elsewhere and migrate later, if ever.
  • Its owned-network advantage is a United States advantage; international coverage arrived through the Voxbone acquisition and does not rest on the same model.
  • Committed volume pricing means an organisation whose traffic falls short of forecast pays for capacity it did not use.

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

Bandwidth: Is Bandwidth a carrier or a reseller?

It is a licensed carrier operating its own US network. That removes the wholesale margin an aggregator pays its upstream and gives direct control over routing and regulatory functions such as E911.

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.

Bandwidth: Do 10DLC fees apply on top of Bandwidth's rates?

Yes. US A2P messaging requires brand and campaign registration with The Campaign Registry, and the registration fees plus per-message carrier surcharges are billed in addition to whatever per-message rate you negotiated.

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.

Source
Bandwidth: Did Bandwidth acquire Voxbone?

Yes, in 2020, for 519.4 million dollars. Voxbone supplied international phone numbering and became the basis of Bandwidth's coverage outside the United States.

Postman: Does Postman have team collaboration?

Team collaboration is not available on the free plan (limited to 1 user). Team plans start at $14/user/month and include shared workspaces, real-time collaboration, and team management features.

Postman: Does Postman work with other development tools?

Postman integrates with Git repositories, offers a Node.js runner (Newman) for automation, and connects with popular CI/CD platforms. Teams using git-native workflows may prefer alternatives like Bruno.
