Jailbreaker: LLM Jailbreak Testing You Can Actually Repeat

Jailbreaker is an open-source evaluation platform from SpecterOps designed to manage and scale manual and automated LLM jailbreak testing: configuring targets (target/attacker/judge roles), selecting technique families, running baselines and experiments across prompt datasets, capturing evidence, and analyzing results via dashboards and SQL-backed reports. The article describes the operator-focused workflow, technique registry (roleplay, prompt injection, iterative attacks, etc.), experiment matrices, and how to clone/run the project locally to make jailbreak testing repeatable and auditable.
