Postman

Postman is a platform for working across the API lifecycle, from design and testing to distribution, documentation, and monitoring. Its API client supports multiple protocols, authentication, response inspection and visualization, variables, environments, and request history. For design work, it supports API specifications, mock servers, importing definitions, multiple formats, and third-party integrations. Testing options include collection runs, automated, integration, performance, regression, and end-to-end testing, plus the Postman CLI. Listed connections include Jira, Slack, GitHub, GitLab, Microsoft Teams, VS Code, Amazon API Gateway, AWS Secrets Manager, and 1Password Vault. Postman describes tools for protecting and resolving secrets, and says customer data is not used to train its models; Enterprise teams control AI access and use. The Free plan is free and includes 50 AI credits, core tools, specifications and mock servers, Native Git, Collection Runner, performance testing runs, and Manual Flows. Solo costs $9 a month billed annually. Postman was founded in 2014 and is headquartered in San Francisco.

Postman brings API client, design, testing, and monitoring capabilities into one platform. The Free plan offers a way to use core tools, while new customers should note the available plan structure and annual billing for Solo.

Postman suits developers and teams that need API design, testing, documentation, or monitoring tools. Its API client, mock servers, testing options, and integrations support different parts of that work.

Overview

Postman is an API lifecycle platform for developers and teams that need to design, test, document, distribute, and monitor APIs. It is best suited to work that spans more than sending requests; the Free plan covers core tools, while paid plans add testing, collaboration, and governance capabilities.

Key features

API work from request to release

The client handles multiple protocols, built-in authentication, response inspection and visualization, variables, environments, and request history. GraphQL and SOAP support broaden its reach, and the combination of request tools with API specifications, imported definitions, and mock servers makes Postman useful across design and implementation. Mock servers and core tools are part of Free, so teams can begin without committing to a paid plan.

Testing includes collection runs, automated, integration, performance, regression, and end-to-end testing, with the Postman CLI, scheduled runs, CI/CD integration, and contract testing also supported. Free includes Collection Runner and performance testing runs; Solo adds data-driven testing with exports and expanded API monitoring. That gives individual users a stronger testing and monitoring package, though team collaboration and governance sit higher in the plan structure.

Integrations and safeguards

Postman integrates with tools including Jira, Slack, GitHub, GitLab, Microsoft Teams, VS Code, Amazon API Gateway, AWS Secrets Manager, and 1Password Vault. It describes local secret protection, cloud secret detection, and runtime secret resolution, with integrations for HashiCorp, AWS Secrets Manager, Azure Key Vault, and 1Password. Its stated compliance credentials include SOC 2 Type II, PCI DSS, HIPAA, GDPR, CCPA/CPRA, CSA STAR, TX-RAMP, ISO 27001, and ISO 42001. Postman says customer data is not used to train its models; Enterprise teams can control AI access and usage. Premium Support, with contractual SLAs and 24/7 global coverage, is an Enterprise-only add-on.

Pricing

Postman is freemium. Free costs nothing and includes 50 AI credits, the API client and core tools, specifications and mock servers, Native Git, Collection Runner and performance testing runs, and Manual Flows. It is a substantial starting point, but Solo and Team provide 400 AI credits per month or per user each month and unlock additional capabilities.

Solo costs $9 a month, billed annually. It adds data-driven testing with exports, unlimited private NPM packages and library, custom-branded documentation, unlimited custom domains, and expanded API monitoring. Its annual billing matters for individuals who want those extras without team features. Team costs $19 a month per user, billed annually, and adds team collaboration, unlimited workspace and collection viewers, basic RBAC, SDK generation and distribution, and the Simple Security add-on. Its per-user annual commitment makes it a better fit for organized teams than occasional collaborators.

Enterprise has custom pricing and includes an API Catalog, Private API Network, advanced RBAC and organization controls, governance, audit logs and reporting, and private test and Flows runners. Teams can trial Enterprise features before upgrading. Basic and Professional are no longer available to new customers; existing Professional customers keep their current plan and pricing.

Platforms

Postman is available as an extension and on Linux, macOS, the web, and Windows. That range suits teams working across desktop environments or through a browser.

Who it's for

Postman is a strong fit for developers and API teams that want client, design, testing, and monitoring tools in one platform, particularly when integrations and security controls matter. Free suits exploration and core API work; Solo targets individual users needing expanded testing and documentation, while Team and Enterprise address collaboration and organizational controls. It is less compelling for users who need only a lightweight HTTP client or a low-cost, non-annual team plan.

Pros and cons

• Pro: API client, design, testing, and monitoring capabilities share one platform, reducing the need to split routine API work across separate tools.
• Pro: Free includes Native Git, mock servers, Collection Runner, and performance testing runs, giving users meaningful core capabilities at no cost.
• Pro: Team and Enterprise add collaboration, access controls, governance, and private runners for organizations with broader needs.
• Con: Solo and Team require annual billing, and Team's price is per user, which can make the commitment less suitable for short-term or irregular use.
• Con: Basic and Professional are closed to new customers, leaving new buyers to choose among Free, Solo, Team, and custom-priced Enterprise.
• Con: Premium Support is an Enterprise-only add-on, so lower-tier customers cannot obtain its contractual SLAs and 24/7 coverage through their plan.

Alternatives

Choose Apidog if its freemium offering and time-unlimited Free plan for four users suit a small team; its Basic plan is $12 a month. SoapUI is a free alternative when REST, SOAP, and GraphQL testing, mocking, and command-line automation are the priority. Choose Insomnia if its free Essentials plan fits a small Git Sync project: it covers three users and 1,000 mock server requests per month. Bruno offers a free Open Source plan with two workspaces and five OpenAPI syncs per month, a narrower starting point for users who can work within those caps. xh is a free open-source command-line HTTP client for users seeking a focused terminal tool.

Testfully is another freemium API tool. Hoppscotch is a freemium alternative, and OpenReq offers a free and open-source option.

Verdict

Postman is the right choice for developers and teams that want API client, design, testing, and monitoring work under one roof, with a Free plan that makes it possible to start without a paid commitment. Look elsewhere if annual billing, per-user Team pricing, or Enterprise-gated support and governance do not match your needs.
