What GoAlert is

GoAlert is open-source software for on-call schedules, alert notifications, and automatic escalation. Teams can use schedules, rotations, and escalation policies to decide who receives an alert and move it to another responder when it is not acknowledged. Alerts can enter through its generic API, email, Grafana, Prometheus, Site24x7, Sensu, or manual entry in the web interface. Notifications include SMS and voice through Twilio, email through Mailgun, and Slack. GoAlert is self-hosted and distributed as a single binary or Docker images; a running PostgreSQL instance is its only hard requirement. Administrators can enable GitHub OAuth or OpenID Connect. The setup guide recommends configuring a data-encryption key for sensitive information, such as API keys, before it is stored in the database. The interface is described as responsive and mobile friendly. GoAlert is free, with no free trial, and is licensed under Apache License 2.0. Two-way SMS is available for US-based numbers; Indian government regulations prevent it for Indian numbers.
