The API platform that everyone uses and few love

Postman owns the API client and platform category through ubiquity and ecosystem. The product has gotten heavier and more sales-led; alternatives like Insomnia, Bruno, and Hoppscotch are credible for teams that want lighter tooling.

Choose Postman if...

Any team that builds or consumes HTTP APIs — especially useful for sharing tested requests across engineering, QA, and partners.

Avoid Postman if...

Teams concerned about sending API traffic through third-party servers — self-hosted Bruno or Hoppscotch are privacy-first alternatives.

Choose Prefect if...

Data engineering teams orchestrating ETL, ML pipelines, or cross-service data workflows who want Python-first ergonomics.

Avoid Prefect if...

Long-running stateful or transactional workflows with strict durability requirements — Temporal is stronger for microservice orchestration.
