Is PubNub worth the price?

75/100

PubNub's pricing offers a generous free tier for initial exploration, but quickly scales up to a $98/month Starter plan.

The jump from free to nearly $100 for basic scaling might feel steep for small projects. It's best for developers and startups needing robust real-time infrastructure with predictable costs at scale.

Hidden Costs & Gotchas

Overage fees for exceeding MAU/transaction limits

Potential for high costs on Pro plan

Add-ons for advanced features not in Starter

Data storage limits on lower tiers

How PubNub Compares to Competitors

Compared to Ably, which offers a free tier up to 3M messages and then usage-based pricing starting around $15/month for basic plans, PubNub's $98/month Starter plan is significantly higher. Firebase Realtime Database offers a generous free tier and then scales based on usage, often appearing more cost-effective for smaller projects than PubNub's fixed Starter fee.
