Open-source uptime, status pages, on-call, APM and logs · by HackerBay, Inc. (OneUptime)

§1

Overview

OneUptime is an open-source project that tries to cover the whole reliability toolchain in one product: uptime and synthetic monitoring, status pages, incident management, on-call scheduling with phone and SMS escalation, OpenTelemetry logs, traces and metrics, error tracking, APM and drag-and-drop workflows. An AI agent can analyse incidents and open fix pull requests.

The hosted service separates plans from usage. The free plan already includes a status page, incident management and telemetry; you pay $1 a month for each active monitor and $0.10 per GB of telemetry. Growth adds unlimited status pages and subscribers, on-call rotations and API access, and Scale adds SSO and access control.

Because it is open source, you can self-host the whole platform instead, which suits teams that want uptime checks, status pages and on-call without several subscriptions. As an all-in-one tool, each individual part is less deep than a specialist product.
