Athar is a self-hosted push notification and growth platform built as an open-source repository on GitHub. The project positions itself as an alternative to hosted engagement tools, with a focus on giving teams control over their data, infrastructure, and messaging workflows.
From the repository description and architecture notes, Athar combines mobile SDKs, a web dashboard, backend services, and data pipelines for sending campaigns, tracking events, and building automated user journeys. The docs folder and iOS workspace entries suggest the project includes implementation and deployment material for running the system across multiple platforms.
