Community Opinions & Reddit Feedback
“A Capterra reviewer from an engineering team wrote that Postman is indispensable for managing API collections, organizing requests by environment, and running integration tests before deploying — praising environment variable management as one of the best features for switching instantly between dev, staging, and production configurations.”
Capterra: Postman Reviews (2026)
“A QA engineer on Capterra noted that Postman made API testing much simpler with its clean UI, easy setup, and strong test management — calling the Newman CI/CD integration particularly valuable and describing it as the go-to tool for API testing despite a few performance and pricing concerns.”
“A G2 reviewer praised Postman for simplifying the entire API lifecycle through a clean UI that works well for developers, architects, testers, and integration teams alike — highlighting strong CI/CD integration, environment management, and AI capabilities that help create tests and understand APIs faster.”
G2: Postman Reviews (2026)
“A senior software engineer on Capterra with over three years of daily use described Postman as a reliable and efficient tool for REST and GraphQL API development, calling its consistency, versatility, and maturity a dependable part of their workflow — and noting they chose it over Apidog specifically for its polish and feature depth.”
“A recurring complaint across Capterra and G2 reviewers is the lack of a fully functional offline mode — many features depend on an active internet connection, which is restrictive in low-connectivity environments or air-gapped development setups.”
“G2 reviewers consistently flag that Postman becomes resource-heavy and slow when handling large collections with many nested folders, with sluggish performance being one of the most cited drawbacks at scale.”
“After Postman tightened its free tier in March 2026 to a single user and just 25 collection runs per month, a wave of developers began evaluating alternatives like Bruno, Hoppscotch, and Apidog — with frustration focused on cloud-sync dependency and free plan restrictions that make team use cost-prohibitive.”

“Enterprise users on PeerSpot flagged that Postman lacks comprehensive integration with third-party test management tools, has no native SOAP API support in newer versions, and has a pricing structure that doesn't reflect value well for teams in regions with currency variation.”

Community Opinions & Reddit Feedback
“A developer writing on Medium described switching from Postman to Bruno after Postman dropped its offline Scratch Pad mode in 2023, praising Bruno's offline-first, Git-friendly approach as ideal for projects with strict security requirements where sending API data to third-party servers is unacceptable.”
Medium: Why I Switched to Bruno for API Testing (2025)
“A Product Hunt reviewer called Bruno a great replacement for Insomnia and Postman once both moved to subscription and account-required models — praising the open-source approach, offline use, and storing collections as readable text files in Git as features that make secret management and versioning feel natural.”
Product Hunt: Bruno reviews (2025)
“A senior quality engineer at a digital product studio wrote that co-locating Bruno collections alongside application code in Git was a revelation — noting that when they delivered a client project, the client received not just an integration but living documentation their technical team could immediately extend and maintain.”
In The Pocket: Bruno – The Lean, Git-Friendly API Client (2025)
“A comparison piece from May 2026 noted that Bruno's GitHub repository crossed 44,000 stars and that adoption inside engineering teams — measured indirectly through .bru files appearing in public repositories — had roughly tripled since Postman's March 2026 pricing change, confirming Bruno as the primary beneficiary of the migration.”
Crosscheck: Postman vs Bruno vs Insomnia (2026)
“Product Hunt reviewers consistently noted that Bruno's UI is less advanced than competitors like Postman or Insomnia — covering the essentials well but lacking the polish of more feature-heavy tools, which can be a friction point for teams coming from richer environments.”
“A 2026 comparison noted that Bruno's protocol coverage, while sufficient for most teams, falls short of Postman's (no MQTT, no built-in MCP client) and Insomnia's (no SSE or Socket.IO), and that GraphQL-heavy teams relying on schema introspection and query autocompletion tend to prefer Insomnia for that specific workflow.”
“The offline-only, no-cloud-sync stance that is Bruno's biggest selling point is also its biggest limitation for teams that need cross-device access or non-Git-based collaboration — there is no web app, no shared workspace, and no way to access collections without a Git repository or manual file transfer.”
