SSL monitoring that
doesn't make you buy an
entire observability stack.
SSL certificates + full HTTP uptime monitoring in one place.
Live TLS probe, Certificate Transparency, new-cert detection, and real downtime alerts via email, Slack & webhooks.
No need for a bloated observability platform.
Every certificate, counting down.
Dive deeper: how the live probe + CT works · why shorter certs are a problem
SSL + Uptime monitoring. One focused tool.
LIVE TLS PROBE
Real handshake on :443. Reads issuer, SAN, chain, TLS version — not just what CT says was issued.
UPTIME MONITORING (UptimeRobot-style)
Any HTTP method, full path/route, expected status codes, keyword match in body. Configurable interval, pause/resume, full history.
CT MONITORING + NEW CERT ALERTS
Certificate Transparency logs + real alerts the moment a new certificate is issued for your domain.
ALERTS ON EVERYTHING
Email, Slack, Webhook (SMS on paid, Teams etc via webhook). 30/14/7/1 for SSL. Immediate on uptime down. Idempotent.
PRIVATE & INTERNAL CERTS
Monitor anything your probe can reach (internal networks via tunnel supported).
FREE TIER + API EARLY
10 SSL + 10 uptime monitors free forever. Full webhooks + REST API from Starter at $15/mo.
Everything under control, at a glance.
Real screenshots from the live dashboard — no staged mockups.
SSL fleet — every certificate, every status, in one table. VALID · EXPIRING · EXPIRED · ERROR · NEW CERT badge when CT detects a new issuance.
Uptime monitors — HTTP checks every 1–60 min. UP / DOWN / PAUSED with latency per check.
Full per-monitor history — response time, status code, and outage windows.
Domain expiry — track WHOIS renewal dates alongside SSL.
DNS monitors — instant alert on any A, MX, TXT, CNAME change.
Public status page — hosted at /s/slug with 90-day uptime bars.
Per-resource alerts — email, Slack, custom webhook. Choose thresholds: 30/14/7/1 days.
Team & RBAC — invite teammates, assign roles, manage pending invitations.
Priced for one job, not a platform.
Webhooks and full REST API from the entry tier. Real CT new-cert alerts + proper uptime monitoring. Free tier is the most generous for both SSL and HTTP checks. See the architecture.
