Postman vs Sentry
Both are developer tools. Here is what separates them.
What Postman is
Postman is a platform for building, testing, documenting and publishing APIs. Its client sends HTTP, GraphQL, gRPC, WebSocket and MQTT requests from a single interface, and requests are grouped into collections that can be shared and run as a suite. Environments hold sets of variables, so the same collection can be pointed at a different target without editing the requests themselves. Testing is done in JavaScript. Pre-request and post-response scripts run around every request, tests are written against a built-in snippet library, and the Collection Runner chains requests, runs them in a set order and logs the results. The same collections run unattended in two other places: Newman and the Postman CLI execute them inside a CI/CD pipeline, and monitors run them on a schedule, support multiple regions and can be restricted with static IP allowlisting. The Postman CLI also lints API schemas and performs security and governance checks. Mock servers return canned responses, so a client can be built before the real API exists. Postman Flows builds runnable workflows on a visual canvas, can embed AI request blocks, and comes with a gallery of more than 100 prebuilt templates. Workspaces come in personal, internal, partner, multi-partner and public forms, and Postman runs a Public API Network for shared APIs alongside a Private API Network for internal ones. Postman runs in a browser, as a desktop application for Windows, macOS on Intel and Apple Silicon, and Linux on x64 and ARM64, and as an extension for VS Code, VSCodium, Cursor and Windsurf. The browser version relies on a separate Postman Agent download to reach local and private networks, and an Interceptor extension is published for Chrome, Safari, Edge and Firefox. The Free plan is $0 and covers a single user, Solo is $9 per user per month billed annually, Team is $19 with unlimited users, and Enterprise is $49. The limits mostly govern volume rather than features: API monitoring is capped at 1,000 requests a month on Free and 10,000 on the paid plans, Postman API calls run from 10,000 a month on Free to 10 million on Enterprise, and deleted collections can be recovered for one day on Free against 90 days on Team and Enterprise.
What Sentry is
Sentry captures application errors and performance data from code running in production. An error report includes a stack trace that shows the values of local variables at each frame, so the state that produced the failure is visible without reproducing it locally, and breadcrumbs record the sequence of events that led up to it. Distributed tracing links a single request across every service and function call it touches, with the SDK sampling rate set through tracesSampleRate. From that data Sentry detects performance problems on its own, including N plus 1 queries, slow database calls and uncompressed assets. Logs can be filtered on structured attributes such as a customer id rather than by matching raw strings. Session Replay covers web frameworks and mobile through React Native, Android, iOS and Flutter, and flags rage clicks and dead clicks where a user taps an element that does not respond. It masks all text, inputs and media by default before a recording leaves the user's browser. Release Health reports crash free session rates, adoption per version and failure rate. SDKs cover JavaScript, Python, Java, Kotlin, PHP, Ruby, Go, Rust, Elixir, Perl, Scala, .NET and native C and C++, along with mobile and game platforms including Android, Apple, React Native, Flutter, Unity, Unreal Engine and Godot. Sentry integrates with GitHub, Jira and Slack, and can assign a new issue automatically to the developer whose commit introduced it. The free Developer plan is limited to a single user seat and includes 5,000 errors, 5 million spans, 50 session replays, 5GB of logs, 5GB of application metrics, one uptime monitor, one cron monitor, 1GB of attachments and 10 custom dashboards, with a 30 day lookback on data. The Team plan costs $26 per month on annual billing, places no limit on seats, raises the error allowance to 50,000 and extends retention to a 90 day lookback. The Business plan costs $80 per month on annual billing and adds unlimited custom dashboards and 1,000 metric monitors, against 20 on Team. Enterprise is quoted individually with custom quotas on every dimension. Usage above an allowance is charged separately: logs and application metrics beyond the included 5GB cost $0.50 per additional GB, extra uptime monitors $1.00 each and extra cron monitors $0.78 each.
