OutageDeck
That's usOutageDeck tracks 96 major cloud and SaaS vendors from their official status feeds, checked about every 10 minutes, and turns changes into email, Slack, Discord, and webhook alerts. Everything is public by default: per-vendor status pages with independent 90-day uptime history, incident timelines, an anonymous JSON API, embeddable badges, and RSS.
Strengths
- Free tier you can actually operate on: email alerts for 5 providers, no notification cap
- Flat $19/mo entry plan with unlimited providers — vendors are never counted as monitors
- Open JSON API, badges, and RSS without an account
- Official sources only, linked from every page — no crowd-noise false positives
Trade-offs
- Curated catalog of 96 major vendors, not thousands of long-tail services
- Alerts fire when the official feed changes — no crowdsourced pre-acknowledgment signal
- No hosted private status boards yet
Best for: solo developers and small teams whose stack is the major clouds and SaaS tools, and anyone who wants status data as an API. OutageDeck pricing
IsDown
The biggest catalog in the category — 6,000+ services — now part of UptimeRobot. IsDown layers crowdsourced problem reports on top of official status pages, so it can often flag an outage before the vendor acknowledges it.
Strengths
- 6,000+ tracked services covers long-tail vendors most aggregators miss
- Crowdsourced early detection, plus its own reporting on incidents vendors never acknowledged
- Native integrations with incident tooling (PagerDuty, Opsgenie, Datadog, ServiceNow) on higher tiers
- Hosted public and private status pages for stakeholders
Trade-offs
- No permanent free plan — a 14-day trial, then from $27/mo for 15 monitors
- Pricing scales with monitor count: watching 150 vendors is the $179/mo tier
- Crowd signals trade some precision for speed — early reports are not official confirmations
Best for: Teams that need maximum vendor coverage, incident-management integrations, and the earliest possible signal. IsDown pricing
StatusGator
The longest-running aggregator, tracking 3,600+ services with aggregated status boards teams can share. Popular with IT departments and education, and it folds your own websites into the same board.
Strengths
- A decade of operating history and 3,600+ tracked services
- Aggregated status boards built for sharing with a whole organization
- Combines vendor status with monitoring of your own sites at 1-minute intervals
- Permanent free plan exists (3 monitors)
Trade-offs
- The free plan caps notifications at 10 per month — enough to evaluate, not to operate on
- Entry pricing starts at $79/mo for 25 monitors; 150 monitors is the $299/mo tier
- Status boards and history depth are gated by plan
Best for: IT teams and organizations that want a shared vendor status board, with their own sites monitored alongside. StatusGator pricing
