What Is Postman?

Postman is the platform teams use to design, test, and document APIs, and it is used by tens of millions of developers around the world. This deal gives a startup engineering team a full year free on the Basic team plan. For a company building software today, where almost everything talks to something else over an API, that is a year of professional-grade tooling for the layer that ties the whole product together, at no cost.

The offer targets exactly the moment where it matters most. Early on, a startup's APIs are changing constantly. New endpoints appear, old ones get reshaped, and the contract between the backend and everything that consumes it is in motion every week. Postman gives the team a shared place to see that contract, exercise it, and keep it documented while it moves. A free year covers the stretch when the product is finding its shape, which is exactly when good API tooling saves the most time.

The core value is that Postman replaces a scattered pile of half-remembered curl commands, private scripts, and tribal knowledge with one system the whole team shares. Everyone works from the same collection of requests, sees the same environments, and reads the same documentation. The API stops being something only its author understands and becomes something the team owns together.

What Is Insomnia?

Insomnia is an API client for testing and debugging REST, GraphQL, gRPC, and WebSocket. This deal provides the free plan, which gives a startup's engineers a capable tool for exercising and inspecting their APIs without adding a cost while the team is small. For any company building or consuming APIs, and that is nearly all of them, this is one of the everyday tools engineers reach for, and having it free from the start is a clean win.

Every backend a startup builds has an API, and every API needs to be tested by hand during development. Before there is a frontend, before there are automated tests, an engineer needs to send a request and see what comes back. Insomnia is built for exactly that. It lets developers construct requests, send them, and inspect the responses across the major protocols a modern product uses, so the team can verify that an endpoint works the way it should before anything else depends on it.

Supporting REST, GraphQL, gRPC, and WebSocket in one tool is the practical strength here. A startup rarely uses only one protocol. It might have REST endpoints, a GraphQL API, gRPC between internal services, and WebSocket for real-time features. Rather than juggling a different tool for each, the team uses one client for all of them. The free plan makes that consolidation cost nothing, which is exactly the right price for a tool every engineer uses many times a day.
