Firebase FCM is push-only infrastructure. You still need: backend server ($20-100/mo cloud hosting), database (Firestore/Realtime DB pay per read/write), user authentication (Firebase Auth setup), Cloud Functions (pay per invocation), storage (pay per GB), analytics (Firebase Analytics separate), and weeks building segmentation, scheduling, admin dashboard. Total: $0 push + $50-200/mo services + weeks of dev time. SashiDo $4.95/mo includes push, MongoDB, user auth, Cloud Code, storage, analytics—complete backend ready to use. Better total value with production support.

No. Firebase Cloud Messaging provides no public SLA, no uptime guarantee, and zero direct support. As a free service, Google makes no reliability commitments. Production issues require posting on Stack Overflow or Firebase forums hoping for community answers (can take days or weeks). No engineers to call, no guaranteed resolution times. SashiDo provides 99.9% uptime SLA on battle-tested Parse Server infrastructure (10+ years stable). Real human support from engineers responds in 8-12 hours. Production-ready reliability with accountability.

Yes! Firebase FCM tokens work the same way on SashiDo because both use native FCM for Android and APNs for iOS. Migration steps: 1) Set up Parse Server on SashiDo (15 min), 2) Migrate Firebase user data to Parse User objects, 3) Store FCM tokens in Parse Installation objects, 4) Replace Firebase Admin SDK calls with Parse.Push.send(), 5) Test delivery. Token format is identical. Bonus: you get complete backend (database, auth, APIs) not just push. See our migration guide guide.

Yes, extensively. Firebase FCM is push-only infrastructure—no segmentation (topics only), no scheduling, no analytics, no admin dashboard, no user management. You build everything. SashiDo includes: Advanced segmentation (MongoDB queries on any user field), Scheduling (Cloud Code with cron jobs), Analytics dashboard (delivery, opens, user engagement), User management (Parse User system with auth), Admin UI (send push from dashboard), Token lifecycle management (automatic cleanup), Real-time diagnostics (delivery status, error codes). Production-ready features, not DIY.

Firebase provides zero direct support—only Stack Overflow and Firebase forums. Production issues require posting questions and hoping for community answers (can take days or weeks). No engineers to contact, no guaranteed response times. Free service means no support commitment. SashiDo includes human support from engineers who know Parse Server and push notifications. 8-12 hour response times (often faster for critical issues). No premium tier required. Real engineers who fix issues, not forum speculation.

If Firebase works for you and you've built custom infrastructure, migration may not be urgent. Consider SashiDo if: 1) You're tired of building everything yourself (segmentation, scheduling, analytics), 2) You need production SLA and direct support (not community forums), 3) You want real engineers to call when issues arise, 4) Firebase service costs are adding up ($50-200/mo for Firestore + Functions + Storage), 5) You want open-source backend you can self-host if needed. Many developers migrate to get complete backend with SLA and support for less than Firebase service costs.
