Features and specs

What each product offers, as listed by its team.

ExpressJS 7 features
ApyGuard 17 features
  • Fast Setup
    ExpressJS provides a minimal and flexible framework that allows rapid setup and development of web and mobile applications.
  • Middleware Support
    ExpressJS has a robust middleware system, allowing developers to add reusable functions to the request-handling pipeline.
  • Extensibility
    ExpressJS is highly extensible through third-party libraries and built-in functionality, catering to the needs of various applications.
  • Performance
    Due to its minimalist core, ExpressJS provides efficient performance and is capable of handling a high number of requests per second.
  • Community and Ecosystem
    A large and active community provides extensive documentation, support, and a wide array of open-source packages to extend functionality.
  • Flexibility
    Compared to full-stack frameworks, ExpressJS gives developers the freedom to structure their applications as they see fit.
  • Compatibility
    ExpressJS works seamlessly with various template engines, databases, and other frameworks, making it versatile for different project requirements.

Possible disadvantages

  • Minimalist Core
    The minimalist nature of ExpressJS may require additional time and effort to integrate required plugins and libraries for specific features.
  • Learning Curve
    While ExpressJS is straightforward, mastering the middleware pattern and effective usage can have a learning curve for new developers.
  • Callback Hell
    Developers can encounter 'callback hell' due to nested callback functions, though this can be mitigated using Promises and async/await in modern JavaScript.
  • Lack of Convention
    Unlike opinionated frameworks, ExpressJS lacks conventions, which can lead to inconsistent code structure and maintenance challenges across different projects.
  • Security
    ExpressJS does not have built-in security features and relies on third-party solutions, requiring developers to be vigilant about applying best security practices.
  • Scalability
    While ExpressJS can handle high traffic, building and maintaining a highly scalable application might require significant additional effort, particularly in terms of codebase organization and resource management.
  • API Security
    Developer-first API security: discovery, documentation, testing, and vulnerability management in one platform.
  • API Security Assessment
    Maps your full API attack surface and delivers a prioritized, evidence-backed risk report.
  • API Security Testing
    Simulates real attacks with payloads tailored to each API's schema and role model to catch broken auth, injection, and authorization flaws before production.
  • API Discovery
    Finds every endpoint your backend actually exposes by analyzing the codebase directly, before deployment.
  • Sensitive Data Detection
    Identifies endpoints exposing sensitive data that needs protection or masking.
  • Behavioral Analysis
    Learns normal API behavior and flags anomalies and business-logic issues beyond schema validation.
  • OpenAPI Documentation
    Generates and maintains OpenAPI specifications from discovered endpoints, so docs never go stale.
  • Business Logic Testing
    Detects logic abuse schema validation can't catch, like users reaching other users' data or skipping workflow steps.
  • OWASP API Top 10 Coverage
    Automated test coverage for the full OWASP API Security Top 10.
  • CI/CD Integration
    Blocks releases on critical findings via GitHub Actions, GitLab CI, CircleCI, and Azure DevOps.
  • Scheduled Scans
    Runs security tests on demand or on a recurring schedule for continuous coverage.
  • Vulnerability Management
    Dashboards for risk posture, trends, and endpoint-level insight, with Jira and Slack routing.
  • Compliance Reporting
    Maps findings to OWASP, GDPR, and PCI DSS requirements for audits and security questionnaires.
  • SaaS
    Cloud-hosted with nothing to deploy — no agents, no traffic mirroring; sign up and run your first scan the same day.
  • On-Premise Deployment
    Self-hosted option for organizations with data residency or isolation requirements.
  • VSCode Extension
    APIScout: free, local-first endpoint discovery and OpenAPI generation in the editor — no code leaves your machine. Also on Open VSX for Cursor and Windsurf.
  • Chrome Extension
    Captures API calls from live browsing sessions to discover endpoints and feed your API inventory.

Questions & Answers

As answered by people managing ExpressJS and ApyGuard.

What makes your product unique?

ApyGuard's answer:

ApyGuard starts from source code, not traffic. Most API security platforms watch production traffic to discover APIs — which means they can only see endpoints that are already deployed and receiving requests. ApyGuard discovers endpoints directly from the codebase, generates OpenAPI documentation from what it finds, and tests for OWASP API Top 10 issues — especially authorization flaws like BOLA and BFLA — before the code ships. It also comes with APIScout, a free VS Code extension (also on Open VSX for Cursor and Windsurf) that runs endpoint discovery entirely locally, so no code ever leaves the developer's machine. And unlike most of the category, pricing is public and self-serve, starting at $129/month.

Why should a person choose your product over its competitors?

ApyGuard's answer:

It depends on your situation, honestly. If you're an enterprise with a security operations team and a six-figure budget, traffic-based platforms are mature options. ApyGuard is built for the teams those platforms don't serve: startups and SMBs that ship APIs every week without a dedicated AppSec department. Compared to spec-first tools, ApyGuard doesn't require you to already have an OpenAPI file — it generates one from your code. Compared to traffic-based tools, it tests pre-production instead of after exposure. Compared to per-endpoint enterprise pricing, it starts at $129/month with a seven-day trial, no credit card and no sales call. You can find out what your API actually exposes the same day you sign up.

How would you describe the primary audience of your product?

ApyGuard's answer:

Backend developers, DevSecOps engineers, and engineering leaders at startups and small-to-mid-sized technology companies — typically SaaS, fintech, e-commerce, and healthcare teams. A fast-growing part of our audience is teams building with AI assistants like Copilot, Cursor, and Claude Code, who need to know exactly which endpoints their AI-assisted codebase actually exposes.

What's the story behind your product?

ApyGuard's answer:

The recurring problem: teams almost never had an accurate picture of the APIs their applications exposed. OpenAPI files went stale, undocumented endpoints shipped every sprint, and the tools that could help were priced and designed for large enterprises. AI coding assistants made the gap worse - code ships faster than anyone documents or reviews it. ApyGuard was built to close that gap from the source code side: discover what's really there, document it automatically, and test it before production - at a price a startup can actually pay.

Which are the primary technologies used for building your product?

ApyGuard's answer:

Python (static analysis and scanning engine) TypeScript (web application and VS Code extension)
