## 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.

#### Which API development software has the best reviews on G2?

The highest-rated API development tools on G2, ranked by review volume, star rating, and likelihood to recommend, cover both standalone API testing and design tools and broader integration platforms.

- [Apidog](https://www.g2.com/products/apidog/reviews): The highest-rated platform in the category among tools with 50 or more reviews, with strong ease-of-use and ease-of-setup scores and a fast-growing reviewer base.
- [Boomi](https://www.g2.com/products/boomi/reviews): A well-reviewed integration and API management platform with representation across SMB and enterprise buyer segments and consistently above-average satisfaction scores.

#### Which API platform is best for microservices architecture?

See the full set of options on the[API Development Software SMB page](https://www.g2.com/categories/api-development/small-business).

- [Postman](https://www.g2.com/products/postman/reviews) **:** The most reviewed platform among SMB buyers in the category by a large margin, with 133 SMB reviews, reflecting its position as the default starting point for small teams and individual developers who need a capable free-tier API tool.
- [Apidog](https://www.g2.com/products/apidog/reviews) **:** The second most reviewed platform among SMB buyers and the highest rated in the category overall, with small team reviewers citing its all-in-one approach to API design, testing, and documentation as a cost-effective alternative to managing multiple tools.
- [Kong Gateway](https://www.g2.com/products/kong-gateway/reviews) **:** An open-source API gateway with a free community edition, reviewed by small teams that need lightweight API management capabilities without committing to an enterprise platform contract.

#### What is the best API development tool for startups?

Startups on G2 prioritize tools that are fast to adopt, well-documented, and capable of supporting team collaboration as engineering headcount grows. These are the most reviewed options among companies with fewer than 50 employees in the category. 

- [Workato](https://www.g2.com/products/workato/reviews) **:** The third most reviewed platform among SMB buyers, rated above the category average, with startup reviewers citing it as a practical fit for teams that need to build and expose integrations quickly without custom infrastructure.
- [Boomi](https://www.g2.com/products/boomi/reviews) **:** The fourth most reviewed platform among SMB buyers with above-average satisfaction scores, reviewed positively by growing teams that need API integration capabilities alongside their core development workflows.
- [Frends](https://www.g2.com/products/frends/reviews) **:** A well-reviewed integration platform with SMB representation in the category, cited by small teams that need a structured API and workflow automation tool that doesn't require a dedicated integration engineer to operate.

#### Which API development tool is the most user-friendly for developers?

Ease-of-use and ease-of-setup scores from G2 reviewers clearly separate a small group of tools that developers find intuitive from platforms that carry a steeper learning curve.

- [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.
- [Postman](https://www.g2.com/products/postman/reviews) **:** The second-highest ease-of-use score among well-reviewed platforms in the category, with a large reviewer base consistently praising its intuitive request-building interface and low barrier to new developers.

#### 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.

#### What API development tools work best for solo developers and consultants?

Solo developers and consultants reviewing API tools on G2 prioritize platforms that are free or low-cost for individuals, portable across client projects, and capable of producing clean documentation and test collections that can be shared without additional tooling.

- [Apify](https://www.g2.com/products/apify/reviews) **:** A well-reviewed platform with above-average ratings in the category, used by individual developers who need to build, publish, and monetize APIs built around data extraction and automation workflows without maintaining their own infrastructure.
- [Workato](https://www.g2.com/products/workato/reviews) **:** Reviewed positively by SMB and individual users building integrations for clients, with above-average satisfaction scores and a reviewer base that includes consultants who need to hand off clean, documented API workflows.

- [MuleSoft Anypoint Platform](https://www.g2.com/products/mulesoft-anypoint-platform/reviews): Reviewed by enterprise teams in financial services for its API security policies, traffic management, and compliance-oriented design, with large organization buyers citing its maturity in regulated industries as a key differentiator.
- [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.
