As answered by people managing DevFinanceTools and SecuryBlack.
SecuryBlack's answer:
SecuryBlack combines three tools into one: continuous email breach monitoring, uptime monitoring, and heartbeat checks for backup verification. Most tools do one of these. SecuryBlack does all three in a single dashboard, so homelabbers and developers stop juggling separate subscriptions.
SecuryBlack's answer:
Uptime Kuma monitors your services but doesn't check breaches. HIBP checks breaches but not uptime. Healthchecks.io verifies cron jobs but nothing else. SecuryBlack replaces all three with one unified dashboard and one subscription at €19/month — or free.
SecuryBlack's answer:
Homelabbers, sysadmins, and developers who self-host services, run automated backups, and want to know immediately if something breaks or their email appears in a data breach. Technical users tired of managing multiple monitoring tools separately.
SecuryBlack's answer:
Built out of personal frustration with tool fragmentation. Running a homelab meant paying for and managing Uptime Kuma, HIBP, and Healthchecks separately. SecuryBlack started as a side project to consolidate everything into one place, and grew into a product for anyone running their own stack.
SecuryBlack's answer:
React (frontend), PostgreSQL, Docker, Rust (telemetry agent OxiPulse via gRPC/OTLP), self-hosted on Hetzner.
