Project mention: Deep Dive: How Bruno 1.0 Stores API Tests Locally vs. Postman 11.0 Cloud Sync | dev.to | 2026-04-28
After 6 months of benchmarking, case study analysis, and real-world testing, our recommendation is clear: choose Bruno 1.0 if you are an engineering team that values performance, Git integration, and zero vendor lock-in. Our data shows Bruno outperforms Postman 11.0 in every local storage metric: 400ms faster startup for 1000+ test suites, 6x lower storage overhead per test, and zero sync latency. The case study above shows teams can save $2k+ per year in licensing costs and $18k+ per year in engineering time by switching to Bruno. For teams with heavy non-technical collaboration needs, or very small test suites (<100 tests), Postman 11.0’s free tier remains a viable option, but we recommend exporting collections to Bruno for all engineering use cases. The API testing landscape is shifting toward local-first tools to avoid cloud vendor lock-in, and Bruno 1.0 is leading that charge. Try Bruno today: download it from https://github.com/usebruno/bruno, and migrate your Postman collections in minutes using the native import tool.

Project mention: Implementing Data Compression in REST APIs with gzip and Brotli | dev.to | 2025-09-03
Let's use the Rick and Morty API as an example. By sending a GET request to https://rickandmortyapi.com/api/location/20 with the Accept-Encoding: gzip header, the API returned compressed data. The server's response included Content-Encoding: gzip, confirming gzip compression was applied to the JSON payload.
