What RedFang is
RedFang is a cloud-based AI red-team scanner for indie builders. It scans AI agents, GitHub repositories, and application URLs, and lists customer-service chatbots among its target systems. Before scanning, it asks users to verify target ownership with a TXT-record or file-upload challenge. RedFang says a scan takes five minutes and returns a grade from A+ to F.
Its seven v1 threat categories include direct prompt injection, tool misuse, sensitive data leakage, output-as-attack-vector, agent overreach, denial-of-wallet, and system-prompt extraction. Repository scans look for exposed keys, broken authentication, and AI-introduced bugs. RedFang says its approach follows the OWASP LLM Top 10 threat model and tests 12 known direct prompt-injection patterns per scan. Reports can include plain-English findings, the working prompt, a curl reproduction command, fix code, and a retest after a fix. The free preview costs nothing and shows the grade and top three issue categories without a credit card. Full reports cost $19 a month. A shareable badge reflects the latest grade; its listed scan cadence varies by tier.
