Mihari
Mihari is a cloud observability platform combining uptime monitoring, on-call alerting, telemetry, API documentation, and error tracking. Its European probes check HTTP, TCP, DNS, and ICMP at intervals down to 30 seconds. On-call tools provide rotation schedules, escalation chains, and notifications through email, SMS, phone calls, Slack, Microsoft Teams, PagerDuty, and webhooks. Telemetry covers logs, metrics, and distributed tracing, with OpenTelemetry and Prometheus ingestion. Error tracking records stack traces, source maps, and contextual breadcrumbs, and groups duplicate errors. The free plan includes 10 monitors, one status page, 1 GB of logs retained for seven days, three dashboards, one documentation project, five team members, one escalation policy, email alerts, and 5K error events monthly. Platform access costs €19 per month; Early Access costs €19 one-time. Mihari is web-based, hosted in France, GDPR compliant by design, and in public beta.
