Built for VAPT Experts. Focused on API Security.

Josh API Analyzer is an API-focused security testing platform designed to help penetration testers, security researchers and VAPT teams assess APIs faster and more efficiently.

Capture traffic, analyze vulnerabilities, manually test requests, fuzz endpoints, manage authentication tokens and generate professional reports — all from one tool.

Why VAPT Professionals Choose Josh API Analyzer

01. API-First VAPT

Built specifically around API security testing, with 25 selectable vulnerability detectors covering the OWASP API Security Top 10 (2023) along with classic and extended API security issues.

02. Capture Real API Traffic

Capture API requests directly from a browser session, Python applications and test scripts, or import an existing HAR file. Start testing from real application traffic instead of building every request manually.

03. Automated Vulnerability Detection

Analyze individual requests or complete captured sessions for vulnerabilities such as BOLA/IDOR, broken authentication, BFLA, SQL Injection, XSS, SSRF, JWT vulnerabilities, business logic issues, race conditions and more.

04. Repeater for Manual Verification

Don't blindly trust automated findings. Send requests to the built-in Repeater, modify parameters, headers or request bodies, replay them and manually verify the behaviour of the target API.

05. Intruder-Style API Fuzzing

Test parameters automatically using Sniper, Battering Ram, Pitchfork and Cluster Bomb attack modes. Use built-in payloads or provide your own payload lists to explore unexpected API behaviour.

06. Authentication & Token Testing

Extract authentication tokens from captured traffic and reuse them during Replay, Repeater and Intruder testing. The built-in Token Decoder also helps inspect JWT headers, claims and algorithm information.

07. Test Multi-Step API Workflows

Modern APIs rarely work as a single request. Josh API Analyzer supports workflow chaining, allowing the output of one request — such as a login token — to automatically become the input of another request.

08. Reduce False-Positive Noise

Detector results use confidence scoring and false-positive filtering before findings are surfaced, helping VAPT teams focus their attention on meaningful results during large scans.

09. Professional VAPT Reporting

Export findings in JSON, CSV, XML and HTML. Generate a technical Developer Report containing evidence, impact, payloads and remediation guidance, or create an Executive Summary for management and stakeholders.

10. Keep Engagement Data Organized

Sessions, requests, responses, findings and tokens are stored locally in a structured SQLite database, giving you a transparent and queryable record of your security assessment.

11. Built-In Team Access Control

Work with different access levels using Admin, Analyst and Viewer roles. Audit logging provides visibility into activity when the tool is used by multiple analysts.

12. Extend It With Python

The tool uses a Python-based architecture, allowing security teams to extend detection capabilities and build additional testing logic without learning a proprietary plugin SDK.

Authorized Testing Only: Josh API Analyzer is intended only for security testing of systems you own or have explicit authorization to assess. Always obtain appropriate permission before performing active security testing.
