Postman has long been a default choice for API developers, with a strong platform to design, test, and debug APIs. Apidog has emerged as a free Postman alternative aimed at API development teams, with up to 4 users and unlimited test runs on the free plan. As of March 1, 2026, the Postman free plan is limited to a single user and 25 collection runs per month—so the gap between Postman and Apidog for small teams has widened. Both tools support the API lifecycle (HTTP requests, responses, validation, design, testing, mocking); the main difference is who they serve and what the free tier allows.
Pro tip: The Postman free plan is now 1 user only. Need free collaboration for 2–4 people and unlimited test runs? Try Apidog—up to 4 users, unlimited test runs, and full API design, mock, and docs at $0. Sign up free (no credit card); import Postman collections and switch in minutes.
Postman: Ideal for API consumers
Postman fits API consumers who need to work with existing APIs quickly. It is strong in these areas:
Ideal use cases:
- Rapid request creation and execution: Build and send requests with different methods, headers, and parameters.
- Organizing requests with collections: Group requests and run them in sequence for workflows or multi-step testing.
- Forking existing collections: Duplicate and adapt public Postman collections.
- Visualizing with Postman Flow: Create request flows and visual representations of API interactions.
Limitations:
- Limited support for APIs in development: Frequent API changes mean rewriting requests and scripts.
- Detached API specification: Specs and collections are separate, so there’s no single source of truth; updates may not sync to collections.
- Postman free plan limitations: From March 1, 2026, the Postman free plan is 1 user only and 25 collection runs per month. More runs or team use require a paid plan (Postman pricing starts at $14/user/month for Team). So Postman is dead for small teams with more than 1 user on the free tier—many look for Postman alternatives like Apidog.
Apidog: Ideal for API development teams
Apidog fits API development teams, especially those working on APIs that change often. It offers up to 4 users and unlimited collection runs on the free plan—no Postman free plan cap. Sign up here.
Ideal use cases:
- Visual API specification creation: Create and update API specs visually as APIs evolve.
- Visual tests and assertions for QA: Build tests and assertions visually; Postman scripts can be reused.
- Real-time updates with API spec changes: Changes in specs flow to requests and tests, reducing manual updates.
- Logical and data flow visualization: Orchestrate requests and data flow between them.
- Auto-generated requests and mock responses: Generate requests and mocks from specs for fast prototyping.
- Unlimited collection runs: No monthly run limit—unlike the Postman free plan (25 runs). Up to 4 users free—unlike Postman’s 1 user.
Limitations:
- Complexity for pure API consumers: If you only need to send a few requests, Apidog’s setup can feel heavier than minimal tools.
- No Postman Flow–style diagram tool: Apidog doesn’t offer a direct equivalent to Postman Flow for diagram-first workflow design.
