Performance
Depending on your server setup and scaling needs, you might encounter performance issues, especially for high-traffic applications, requiring constant monitoring and fine-tuning.
Limited Scalability
Parse might not be as scalable as other backend solutions like Firebase, particularly for apps that need to handle massive amounts of data and users.
Initial Setup Time
The initial setup of a Parse server and its environment can be time-consuming and challenging, particularly for those without DevOps experience.
Feature Limitations
While Parse offers a rich feature set, some advanced features available in other modern backend-as-a-service (BaaS) platforms may lack, necessitating custom development.

Cost
While Fly.io offers a free tier, the cost can become significant as you scale your applications.
Limited Language Support
Fly.io supports fewer runtime environments and languages compared to more established platforms like AWS or Azure.
Platform Maturity
As a relatively new platform, Fly.io may lack some advanced features and ecosystem integrations offered by more mature competitors.

Supabase Alternatives 🔄 in 2025 😼

Supabase Series B
Not to crash the party or anything. Supabase is great and all but in terms of feature completeness and getting actual products built, it doesn't come close to Parse[0]. Same with Appwrite. Both of these are very popular but they either lack essential features or have them behind a subscription wall. For example, the OSS version of Supabase (last I checked) doesn't include the edge functions which are really... - Source: Hacker News / about 4 years ago
