Firebase Cloud Messaging vs TrackJS

Both stand on error monitoring software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

Firebase Cloud Messaging

Free plan AndroidAPIExtension+2

FCM provides message delivery options and targeting for a range of client platforms at no listed cost. Web projects need HTTPS, and sensitive-data apps must add their own end-to-end encryption.

TrackJS focuses on contextual frontend error monitoring with privacy controls, integrations, APIs, and optional AI analysis. Its paid plans, retention periods, and per-minute error limits should guide plan selection.
