Facts

Purpose

GateSentry is an open-source HTTP/HTTPS proxy and DNS sinkhole with a web admin dashboard for home and small networks.github.com · 5 Oct 2026

Filtering

It supports DNS blocklists, per-device or per-user policies, scheduled rules, safe search, keyword filters, and content filters.github.com · 5 Oct 2026

HTTPS inspection

Optional HTTPS inspection can match URL paths and response content types when traffic is routed through the proxy and clients trust its CA certificate.github.com · 5 Oct 2026

AI image filtering

Optional AI image filtering is disabled by default and supports xAI, OpenAI, or an operator-configured Ollama endpoint.github.com · 5 Oct 2026

Visibility and recovery

The dashboard provides logs, statistics, device inventory, and backup and restore functions.github.com · 5 Oct 2026

Deployment

GateSentry can run as a Docker container on Linux or as a downloadable binary for Linux, macOS, and Windows.github.com · 5 Oct 2026

Audience

The project describes GateSentry as useful for network-wide content filtering, privacy guarding, parental controls, and blocking known-bad domains.github.com · 5 Oct 2026

Security defaults

The maker says the defaults are intended for a trusted local network and are not hardened for direct Internet exposure; the admin UI uses plain HTTP.github.com · 5 Oct 2026

Filtering limits
