Convex may suit you better if…
- You want end-to-end TypeScript and automatic reactivity
- You prefer writing backend logic over SQL
- You build highly collaborative realtime UIs
Compare
Da8a vs Convex
Convex is a reactive backend where queries and mutations are TypeScript functions and clients stay in sync automatically. Da8a is Postgres with SQL, row-level security and supabase-js, on a server of your own.
| Topic | Da8a | Convex |
|---|---|---|
| Data model | Relational Postgres 16 with SQL | Document-relational tables accessed through TypeScript functions |
| How clients read data | supabase-js REST queries and Realtime subscriptions | Reactive queries that re-run when data changes |
| Access control | Row Level Security policies in SQL | Checks written in your server functions |
| Functions | Deno edge functions | Queries, mutations, actions and scheduled functions |
| Where it runs | A dedicated server of your own, managed for you | Convex cloud, or the open-source backend you host |
| Pricing model | A flat price per server | Plan tiers plus usage |

Da8a may suit you better if…
- You want SQL, joins, extensions like pgvector, and standard Postgres tools
- You want policies enforced in the database
- You want a flat price on your own server
Switching to Da8a

jsonbcolumns. - Move mutations into SQL functions or edge functions.
- Replace
useQuerywith supabase-js queries and Realtime channels.
