While there is documentation available, it can sometimes be sparse or outdated, making it difficult for users to find solutions to specific issues.
Dependency Overhead
Karma requires multiple dependencies and plugins to function effectively, which can increase the complexity of the project setup and maintenance.

Possible disadvantages of Supabase

New and evolving
As a relatively new platform, Supabase is still evolving, which means it might lack some features found in more mature solutions and could have occasional bugs or stability issues.
Limited integration
Currently, Supabase has fewer third-party integrations compared to other established backend-as-a-service (BaaS) providers, which might limit its utility in diverse tech stacks.
Learning curve
Despite its user-friendly interface, there could be a learning curve for those unfamiliar with PostgreSQL or real-time database concepts.
Pricing for advanced features
While Supabase offers a free tier, advanced features, and higher usage plans come with a cost. This might be limiting for startups or hobby projects with tight budgets.
Limited geographic presence
Supabase's infrastructure might have limited geographic data centers compared to larger cloud providers, potentially affecting latency and performance for users in certain regions.
