Restorm or Postman?
Postman is the reference tool for API testing. This page says where Restorm is different — starting with the fact it designs APIs, not only tests them.
In brief
Section titled “In brief”| Restorm | Postman | |
|---|---|---|
| Executable protocols | 15, including Kafka, AMQP, Redis, STOMP, OData, tRPC | HTTP, GraphQL, gRPC, WebSocket, MQTT, Socket.IO |
| API design | Visual designer + 5-protocol mock + client and doc generation | Cloud-side API editor |
| Project storage | A file on your own disk, version-controllable | Hosted, synchronised workspace |
| Sharing | git | Collaborative workspace |
| Chaining | Visual scenarios (90 box types) | JavaScript scripts + Collection Runner |
| Scripting languages | 7 (TS, JS, Python, Lua, Ruby, R, C#) | JavaScript |
| Mock servers | Local, 6 protocols, offline | Hosted |
| Network firewall | Yes, every outbound call vetted | No |
| AI driving | Built-in MCP server — drives the app (interface, execution, screenshots) | Separate MCP server, on the cloud API side |
| Record a web page | Built-in mini browser + replayable route deduction (REST, GraphQL, gRPC-web, WebSocket) | Proxy / traffic interception |
| Licensing model | Capabilities, no quotas | Per seat, with quotas |
The differences that really matter
Section titled “The differences that really matter”Design, not just test
Section titled “Design, not just test”Restorm is not just a client: it is also an API designer. Model an API by hand — models, enums, routes — then serve it as a mock in HTTP, GraphQL, SOAP, OData and gRPC all at once, and generate its clients and its documentation, without writing a line of spec. Postman offers a cloud-side API editor; Restorm designs, simulates and generates locally, in the same tool as your tests.
The project is a file
Section titled “The project is a file”This is the structural difference. A Restorm project is a YAML file sitting in your repository: your requests follow the same review cycle as your code, their history is the git history, and the access rights are your forge’s.
Serialisation is deterministic — canonical key order, stably derived identifiers — so
that git diff stays readable. See
.restorm projects and files.
Scenarios replace scripts
Section titled “Scenarios replace scripts”Where Postman asks you to write JavaScript in Pre-request and Tests tabs scattered across the collection, Restorm offers a graph: the flow is visible, branches and loops are boxes, and the execution order is the drawing rather than an implicit property of the collection.
When the graph is not enough, the Code box is there — in seven languages.
Protocol coverage
Section titled “Protocol coverage”Kafka, AMQP, Redis, STOMP, OData, tRPC and JSON-RPC are first-class request types, with their own editor and their own execution. See the protocol catalogue.
In practice: testing an event-driven system — REST call, Kafka message, MQTT notification — fits in a single project and a single scenario.
The firewall
Section titled “The firewall”Restorm blocks by default every outbound call that does not come from a URL in your project, and asks you for authorisation. See Firewall. That is a guarantee no other API client offers.
The licensing model
Section titled “The licensing model”Restorm gates capabilities, never quotas: no limit on requests, collections or calls. The purchase trigger is running in continuous integration. See Plans and capabilities.
Migrating
Section titled “Migrating”Your collections import as they are, scripts included — the pm.* compatibility layer
makes them work with no rewriting. See
Migrating from Postman.
