When to Choose Convex
- If you’re a 10-person startup with a simple Realtime Backend requirement and a budget under $5,000 per month, Convex is a more cost-effective option.
- If you prioritize ease of use and a simple learning curve, Convex is a better choice, with most developers able to set up a basic project in under 3 days.
- If you need to handle a small to medium-sized user base (less than 10,000 concurrent connections) and prioritize automatic caching for reactive queries, Convex is a better fit.
- For example, if you’re a 20-person SaaS company needing to build a simple chat application with Realtime Backend, Convex can help you get started quickly and efficiently.
When to Choose Supabase
- If you’re a 50-person enterprise with a complex Realtime Backend requirement and a budget over $10,000 per month, Supabase is a more scalable option.
- If you prioritize customization and control over your Realtime Backend, Supabase offers more advanced features and configuration options.
- If you need to handle a large user base (over 10,000 concurrent connections) and prioritize priority support, Supabase is a better choice.
- For instance, if you’re a 100-person e-commerce company needing to build a complex Realtime Backend with multiple integrations and custom caching, Supabase can provide the necessary scalability and support.
Real-World Use Case: Realtime Backend
Let’s consider a Realtime Backend use case where we need to build a simple chat application with 100 concurrent users. With Convex, setup complexity is around 2-3 hours, and ongoing maintenance burden is relatively low. The cost breakdown for 100 users would be around $50 per month. However, with Supabase, setup complexity is around 5-7 days, and ongoing maintenance burden is higher due to manual caching requirements. The cost breakdown for 100 users would be around $25 per month for the free plan, but would increase to $100 per month for the paid plan with priority support. Common gotchas include handling connection limits and optimizing query performance.
Migration Considerations
If switching between Convex and Supabase, data export/import limitations include a maximum of 100,000 rows per export. Training time needed to learn the new platform would be around 3-7 days. Hidden costs include potential increases in query costs due to differences in pricing models.
