Building Security Testing Tools
The story began on 14 June, when a Dev.to author said they built a free cybersecurity scanner that gives any website a security score. NewsHive first detected the thread on 15 June. On 23 July, another Dev.to post said MythX had shut down in March and that the post’s author built a replacement because nothing had taken its place.
By 9 August, a developer had tested a security extension against 20 real sites and found three bugs in their own tool, an admirably efficient reminder that scanners also need scanning. Other Dev.to reports described an audit of a vibe-coded SaaS that found five critical vulnerabilities in five minutes; an open-sourced AI security scanner; an AI-powered smart contract auditor seeking developer feedback; concerns about deployment security headers; a tool built to replace 10 separate developer tools; and Cursor hardcoding API keys. Another post framed Apple’s killing of a $100 million vibe-coding app as a security story. OpenAI invited developers to try its new Codex Plugin Scanner and compare scores.
Taking this as factual, impact is 0%. Developers have more self-built and open-source security-testing options to examine. These reports establish no measured change for users, vendors, or the wider security market.
Watch for independent test results, public fixes for the three bugs, and evidence that developers adopt these scanners beyond their creators’ demonstrations. Clear details about the MythX replacement would also sharpen the picture.
