Apify

Apify is the largest marketplace of tools for AI. At its core is Apify Store, a marketplace where builders create, publish, and monetize tools called Actors. Actors are serverless cloud programs that get web data and automate tasks on the web. Builders create them with JavaScript or Python. Build an Actor once and publish it to Apify Store. Thousands of builders already have. Earn when others use it - Apify handles all the infrastructure, billing, and monthly payouts. For everyone else, Apify means never building from scratch. Apify Store has thousands of ready-to-run Actors for extracting Amazon product data, scraping Google Maps listings, monitoring competitor prices, pulling social media content, generating leads, and hundreds of other jobs on the web. Pick the Actor you need, run it, and get your data. Behind the scenes, Actors handle proxy rotation, CAPTCHA solving, JavaScript rendering, headless browsers, scaling, storage, and scheduling. The Apify platform runs with 99.95% uptime. It's SOC 2 Type II, GDPR, and CCPA compliant, and trusted by companies and organizations such as Intercom, Groupon, and the European Commission. Run Actors through Apify Console, integrate them with Zapier and Make, or connect them to AI frameworks like LangChain and Hugging Face to feed LLMs and vector databases. Apify's MCP server lets AIs like Claude discover and use Actors as tools dynamically, so an agent can ask "find the top 10 Indian restaurants in San Francisco" and automatically use the right Actor to get that data. Use cases span competitive intelligence, lead generation, market research, SEO monitoring, and crawling websites for AI context. If there's data on the web, there's probably an Actor for it. Apify has residential and datacenter proxies, browser automation with Puppeteer and Playwright, automatic retries, error handling, monitoring dashboards, and APIs. Schedule runs to keep data fresh and export to JSON, CSV, Excel, Google Sheets, databases, or push straight into your workflows. Beyond Apify Store, the Professional Services team builds and maintains custom solutions with dedicated data experts and long-term project maintenance. Start free with $5 in prepaid monthly platform usage; paid plans scale with compute, storage, and proxy usage (see https://apify.com/pricing).

Small Business FAQs

What is the most affordable API development tool for small businesses?

Cost and accessibility are primary concerns for small teams and individual developers evaluating API tools on G2, with buyers in this segment favoring platforms that offer generous free tiers or low-cost entry points without sacrificing core functionality. See the full set of options on the API Development Software SMB page.

  • Postman: 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: 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: 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: 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: 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: 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: 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: 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.
  • Boomi: Scores above WSO2, Kong, and MuleSoft on ease-of-use among platforms with 20 or more reviews, with reviewers noting its visual integration designer as a more accessible entry point for teams new to API management platforms.

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: 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: 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.
  • Frends: A platform reviewed by small teams and individual practitioners for its low-overhead approach to API and integration workflow management, with satisfaction scores above the category floor among its reviewer base.

What is the most reliable API development platform for enterprises?

Enterprise engineering teams on G2 evaluate reliability through API gateway uptime, platform performance under load, quality of vendor support, and stability of integrations with existing development toolchains.

  • MuleSoft Anypoint Platform: Among the most enterprise-reviewed platforms in the category, with large organization reviewers citing its maturity and depth as a reliable foundation for managing APIs and integrations in production environments at scale.
  • Kong Gateway: Reviewed by enterprise teams for its API gateway performance and open-core architecture, with engineering organizations citing its lightweight footprint and horizontal scalability as reliability strengths under high traffic loads.
  • Boomi: Reviewed across both SMB and enterprise segments with consistently above-average satisfaction scores, with enterprise buyers citing platform stability and a broad connector library as key factors for production reliability.

What is the best-reviewed API development tool for enterprise app integration?

Integration depth is the most critical evaluation criterion for enterprise buyers in this category, with large organizations prioritizing platforms that can connect internal systems, third-party services, and external APIs without creating long-term maintenance overhead.

  • MuleSoft Anypoint Platform: The most enterprise-focused platform in the category by reviewer composition, with large organization reviewers consistently citing its integration runtime, connector ecosystem, and API management layer as primary reasons for selection over other tools.
  • WSO2 API Platform: Reviewed positively by enterprise buyers for its flexibility in managing APIs across hybrid and multi-cloud environments, with above-average enterprise satisfaction scores from teams running complex integration topologies.
  • Workato: The highest-rated platform among enterprise-reviewed tools with 10 or more enterprise reviews, with large organization buyers citing its pre-built connector library and low-code automation layer as strengths for connecting enterprise applications through APIs.

Which API development platforms are best suited for financial services enterprises?

Financial services and banking together represent the largest non-technology industry segment in G2 reviews for this category, with buyers in these verticals placing particular weight on security controls, audit logging, and compliance with data handling requirements.

  • MuleSoft Anypoint Platform: 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: 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: 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.
