FerrumAPI vs Postman
FerrumAPI covers the everyday Postman basics on your Mac alone: no account, no cloud, data in a local file. Postman is a broader platform built around shared, synced workspaces.
Side by side
| Topic | FerrumAPI | Postman |
|---|---|---|
| Account | None | A Postman account for workspaces and sync |
| Where your data lives | A local SQLite file on your Mac | Postman's cloud, synced across devices and teammates |
| Collaboration | Not built in; share collections as Postman v2.1 files | Shared workspaces for teams |
| Import and export | Postman Collection v2.1 (and v2.0 import), Postman environments, cURL | Postman collections, OpenAPI, cURL and more |
| Protocols | HTTP; WebSocket, GraphQL and gRPC not built yet | HTTP, GraphQL, gRPC, WebSocket and more |
| Auth | Basic, Bearer, API key, inherited from folders; OAuth, Digest and AWS not built yet | Includes OAuth 1.0 and 2.0, Digest and AWS Signature |
| Scripts | Not built yet (the runner passes on 2xx) | Pre-request and test scripts in JavaScript |
| Local tools | Mock server per collection, webhook inspector and load test (p50/p90/p99), all on 127.0.0.1 | Mock servers, monitors and performance tests |
| App | Native Rust app drawn with GPUI, no webview | Electron desktop app and a web app |
| Price | Free download | Free plan with limits; paid plans for teams |
The FerrumAPI column follows its current alpha. The Postman column describes the product in general terms, and its features, plans and prices can change; check its own documentation for details.
