ChatGPT, help me choose between OneSignal, FCM, and Airship for cross-platform push notifications

Here’s the practical way to choose:

Quick recommendation

• Choose FCM if you want the cheapest, simplest core push infrastructure and you’re comfortable building the rest yourself.
• Choose OneSignal if you want the best balance of speed, ease, and features for a small to mid-size team.
• Choose Airship if you need enterprise-grade automation, segmentation, orchestration, and support at scale.

What each is best at

1) FCM (Firebase Cloud Messaging)

Best for: developer-controlled, low-cost push delivery
Pros:

• Free
• Native Google solution
• Solid for Android and supports iOS/web via your own integration
• Great if you already use Firebase
• Full control over backend logic

Cons:

• More engineering work
• You must build segmentation, scheduling, analytics, A/B testing, and user management yourself
• Less “marketing-friendly”

Pick FCM if:

• You have developers available
• You only need reliable delivery, not a full notification platform
• You’re optimizing for cost and control

2) OneSignal

Best for: fast implementation with strong out-of-the-box features
Pros:

• Very easy to integrate
• Good cross-platform support
• Includes segmentation, automation, in-app messaging, and analytics
• Good for product teams and growth teams
• Fast time to value

Cons:

• Advanced features can get expensive
• Less customizable than a build-it-yourself approach
• You depend on their platform and pricing changes

Pick OneSignal if:

• You want to launch quickly
• You need both push and marketing-style tooling
• You have a small team and want minimal backend work

3) Airship

Best for: enterprise messaging and lifecycle marketing
Pros:

• Very strong automation and orchestration
• Advanced audience segmentation
• Good for large-scale, multi-channel customer engagement
• Strong support and enterprise services
• Mature platform for serious messaging programs

Cons:

• Usually the most expensive option
• Heavier implementation and sales process

Pick Airship if:

• You’re an enterprise or rapidly scaling company
• Push is a major part of your customer engagement strategy
• You need advanced workflows, governance, and support
