isitsecure is a free, open-source security scanner that lets web developers test their applications for vulnerabilities using static analysis, live-app testing, and AI code review in one command. The scanner is available now and works with popular frameworks like Next.js, Django, and Spring Boot, with optional AI-powered fixes that can be integrated into development workflows.

A developer released isitsecure, a free and open-source security scanner that combines four scanning approaches—SAST (static code analysis), DAST (live app testing), LLM-powered code review, and AI fix generation—in a single command. It runs 40 rule-based scanners by default, or up to 44 with the --depth deep flag, and supports TypeScript/JavaScript, Python, Java/Kotlin, and any HTTP API.
Why it matters
Developers can scan their web apps for vulnerabilities without needing separate commercial tools or deep security expertise. The scanner automatically connects findings to tests—for example, if code shows no authentication check, it sends an unauthenticated request to verify the flaw is exploitable—and generates code patches developers can paste into their editor or AI assistant.
What to watch
The tool is free for rule-based scans (no API key needed). LLM-powered features cost an estimated $5–8 for code-only review or $10–15 for a full scan, using Anthropic Claude or Google Gemini APIs. Installation requires Python 3.11+ and git; the web UI is available via isitsecure launch.
isitsecure addresses a gap in developer tooling by bundling multiple security scanning approaches into a single, free command-line interface. Historically, developers have had to choose between separate static analysis, dynamic testing, and code review tools—each with its own setup and learning curve. By automating the connection between code findings and live-app tests, and adding AI-driven fix generation, the tool reduces friction for teams that want to shift security earlier in the development cycle.
The scanner's support for multiple frameworks (Next.js, Django, Spring Boot, FastAPI) and its modular installation (developers can add browser-based testing or LLM features as needed) suggests it is designed for rapid integration into existing CI/CD workflows. The estimated cost of $5–15 per full scan, when LLM features are used, is positioned as a low barrier compared to traditional commercial security tools, which may require enterprise licensing or per-developer seats.
