What Lerix does
Error tracking
Crashes and errors grouped by fingerprint, ranked by users affected, with device, OS, version and breadcrumbs. An AI assistant reads the stack trace against your GitHub repo and explains the cause.
Push notifications
APNs, FCM and Web Push from one screen. Topics, scheduling, images, custom sounds, per-device delivery status, and update or unsend after delivery.
AI agents (MCP)
A native MCP server so any agent that speaks MCP can create projects, generate push credentials and manage topics for you.
REST API
Send, update, unsend and cancel notifications, and read deliveries, from your own backend.
