skalert

Skalert is a cross-platform, open-source framework designed to manage and deliver alerts from diverse data sources to users and systems in real time. It provides a centralized model for defining alert rules, routing logic, and notification channels, enabling organizations to scale incident notification across distributed environments. The name blends 'sky' and 'alert' to evoke broad visibility and timely warnings.

Architecture and data model: Skalert consists of alert producers, a processing engine, and delivery modules. It supports pluggable backends and connects to common message queues and data streams. At its core is an alert object with fields such as id, source, severity, timestamp, status, and metadata. The rule engine supports correlation, deduplication, and silencing, while the routing layer determines which channels receive each alert.

Features: real-time processing, high throughput, fault tolerance, multi‑channel delivery (email, SMS, chat, webhooks, mobile push), templating, and localization. It offers rate limiting, escalation policies, and audit trails. Extension is possible through plugins and adapters for monitoring tools, incident management platforms, and data sources.

History and status: Skalert emerged from a community-driven effort to unify alerting across disparate monitoring stacks. It has seen multiple major releases, with active development and regular documentation updates. Adoption is strongest among mid‑sized organizations and open‑source projects that require centralized notification orchestration.

Deployment and considerations: Skalert can be deployed on‑premises or in cloud environments, and is designed to operate alongside existing monitoring and observability stacks. Users should plan for schema maintenance, access control, data privacy, and scale management in larger deployments. Potential limitations include configuration complexity and the need for careful policy design to avoid alert fatigue.
