# Best API Development Tools - Page 2

  *By [Adam Crivello](https://research.g2.com/insights/author/adam-crivello)*

   API development tools allow users to design, build, simulate, and fully test the functionality of their custom-built application programming interfaces (APIs) in a secure environment. These tools help the user with the pre-production requirements for APIs by enabling developers to ideate, set design guidelines, and ultimately build and test APIs under one dashboard. Once an API is published, developers use [API management tools](https://www.g2.com/categories/api-management) to govern it. Some [API marketplace](https://www.g2.com/categories/api-marketplace) solutions contain tools for editing APIs, but those tools are less focused on developing and managing an API and are more focused on choosing external APIs to benefit the actual product.

To qualify for inclusion in the API Development category, a product must:

- Provide native tools to design and develop APIs
- Allow parallel development and team-wide visibility throughout the development process
- Provide simulation and testing capabilities for pre-production APIs

## How Do You Choose the Right API Development Tools?

### What You Should Know About API Development Tools

### Most Popular FAQs

#### What are API development tools?

API development tools are software platforms that help developers build, test, document, and manage APIs throughout the development lifecycle. They typically include features for designing API schemas, sending and inspecting requests and responses, automating test suites, generating documentation, and, in more advanced platforms, managing API gateways, versioning, and access controls. The category spans lightweight tools used by individual developers for quick testing all the way to enterprise platforms that govern API infrastructure across large organizations. The right tool depends on whether a team primarily needs a testing and documentation workflow or a full API lifecycle and integration management layer.

#### What does API mean in software development?

API stands for Application Programming Interface. In software development, it refers to a defined set of rules and protocols that allow one application to communicate with another without exposing the underlying code. APIs are how modern software systems exchange data and trigger actions across services — connecting front-end interfaces to back-end logic, pulling data from third-party platforms, or integrating tools like CRMs, payment processors, and databases. In a business context, APIs are the connective tissue between the tools and systems an organization runs on.

- [Apidog](https://www.g2.com/products/apidog/reviews) **:** Earns the highest ease-of-use score in the category among all platforms with 20 or more reviews, with developers citing its interface design and workflow consolidation as reasons it requires significantly less ramp-up time than alternatives.

#### How do small development teams manage API documentation without a dedicated technical writer?

This is a recurring challenge flagged in SMB reviews across this category on G2. Most modern API development platforms generate documentation directly from the API definition or test collections, eliminating the need for a separate documentation process entirely. Reviewers in small teams most commonly solve this by selecting a tool that produces documentation as a built-in output of the development workflow, rather than treating it as a downstream task, keeping it in sync with the API as it evolves. The platforms most frequently cited for this in SMB reviews are those that consolidate API design, testing, and documentation in a single interface rather than requiring separate tooling for each stage.

- [WSO2 API Platform](https://www.g2.com/products/wso2-api-platform/reviews): Noted by enterprise reviewers for its open-source flexibility and strong security layer, a fit for financial services teams that need to maintain direct control over their API infrastructure rather than relying on a fully managed SaaS platform.
- [Frends](https://www.g2.com/products/frends/reviews): A platform with enterprise representation in its reviewer base and above-average satisfaction scores, reviewed by teams in regulated industries that need a structured integration and API workflow tool with clear auditability.

#### What do enterprise buyers most commonly dislike about API development software?

The most consistently cited dislikes include steep learning curves for platforms with broad feature sets, pricing that scales aggressively with usage or team size, and documentation that doesn't keep pace with platform updates. For integration-focused platforms like MuleSoft, reviewers frequently flag implementation complexity and dependence on specialized expertise as high ongoing costs beyond licensing. Postman enterprise reviewers cite collaboration feature limitations and version control at scale as recurring pain points. Evaluating onboarding support quality and total cost of ownership, including professional services, is strongly recommended before committing to an enterprise contract.
