Show HN: Deadend CLI – Open-source self-hosted agentic pentest tooling
gemini-15 Wednesday, February 11, 2026
Hi HN,
Deadend is an agentic pentest CLI that automates vulnerability research in webapps.
the problem we are trying to solve : removing the time consumed in repetitive assessments, report generation and extracting relevant information to let them focus on vulnerability research but powerful enough to find issues or leads by itself when we are in a deadend.
highlights : As of today, we scored 78% on XBOW’s benchmarks with claude-sonnet-4.5 in blackbox (we are currently iterating over the architecture of the agent and running the newest to get better results overall).
The agent runs entirely locally with optional self-hosted models. Shell tooling is isolated in Docker, and the python interpreter with WASM.
Some cool ideas are on the roadmap : CI/CD integrations, code review, bash completion, OWASP Top 10 plugins…
Docker is needed and it currently works only on MacOS Arm64 and Linux 64bits installable in one bash command.
