ApyGuard is a developer-first API security testing platform that finds vulnerabilities and authorization flaws before they reach production.

Most teams don't have an accurate picture of the APIs their applications actually expose. OpenAPI files go stale, and AI coding assistants (Copilot, Cursor, Claude Code) generate endpoints faster than anyone documents them. Traffic-based security tools only see APIs that are already deployed โ€” ApyGuard starts from the source code, so it catches issues before exposure, not after.

How it works:

  • Discover โ€” endpoints are found directly in your codebase (FastAPI, Django, Flask, Express, NestJS), including shadow endpoints missing from your specs
  • Document โ€” OpenAPI specifications are generated automatically and kept in sync with the code
  • Test โ€” full OWASP API Security Top 10 coverage, with emphasis on BOLA, BFLA, and broken authentication; attack payloads are tailored to each API's schema and role model instead of generic fuzzing
  • Fix โ€” findings are ranked by exploitability and include remediation guidance, routed to Jira/Slack

Ships with your pipeline: CI/CD security gates for GitHub Actions, GitLab CI, CircleCI, and Azure DevOps. Integrations with GitHub, GitLab, Jenkins, Postman. Findings map to OWASP, GDPR, and PCI DSS requirements to support compliance reporting. On-premise deployment available.

Start free in the editor: APIScout, our free VS Code extension (also on Open VSX for Cursor and Windsurf), discovers endpoints and generates OpenAPI specs entirely locally โ€” no code leaves your machine, no account required.

Transparent pricing: self-serve plans from $129/month, seven-day free trial, no credit card, no sales call. Built for startups and SMB teams shipping APIs without a dedicated AppSec department.

Possible disadvantages of api-usage

  • Limited API Coverage
    The platform might not include all available APIs, potentially missing niche or newly released services that could be relevant to some users.
  • Outdated Information
    Information on the platform may not be updated in real-time, leading to discrepancies between the listed data and the actual current state of an API.
  • Lack of Personalization
    The platform may not offer personalized recommendations based on specific user needs or previous usage patterns, limiting its utility for tailored searches.
  • Dependency on User Input
    If the platform relies on user-generated content for reviews or ratings, the quality and reliability of this information can vary significantly.
  • Potential Overwhelm
    With numerous APIs and data points available, new users might find it challenging to navigate and extract the most relevant information for their specific use case.

ApyGuard features and specs

  • 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.

    Cloud-hosted with nothing to deploy โ€” 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 โ€” 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.

Analysis of api-usage

Overall verdict

  • Without independent verification, api-usage (apiusage.info) cannot be confidently confirmed as a good or reliable service since there is insufficient public information, reviews, or track record available to assess its quality, security, and support.

Why this product is good

  • Limited publicly available information makes it difficult to verify claims about the service
  • No substantial user reviews or third-party assessments found to confirm reliability or performance
  • Unclear track record regarding uptime, customer support quality, or data security practices
  • Potential newer or niche player in the API monitoring/usage tracking space with limited market validation

Recommended for

  • Users willing to conduct their own due diligence and testing before committing
  • Those seeking a possibly low-cost or niche alternative to established API usage tracking tools
  • Developers comfortable trying newer services and providing feedback
  • Not recommended for enterprises requiring proven, well-documented vendor reliability without further research

Questions & Answers

As answered by people managing api-usage 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 โ€” 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 โ€” especially authorization flaws like BOLA and BFLA โ€” 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 โ€” 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 โ€” 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)
