Supabase as Default AI Backend
Convex
Supabase won the AI coding wave because it is the easiest relational backend for an LLM to safely suggest in one shot. Postgres gives generated apps a familiar table model, and Supabase wraps that database with auth, storage, realtime APIs, functions, and a dashboard, so an AI tool can point users to one service instead of stitching together five separate products. That simplicity helped make it the default backend in many AI app creation flows.

For an AI coding product, recommending Supabase is easy because the setup maps cleanly to common app prompts, create tables in Postgres, add login, store files, call APIs. Supabase monetizes across database usage, bandwidth, and monthly active users, so each successful generated app can expand into durable recurring revenue.

The contrast with PlanetScale shows why feature breadth matters. PlanetScale is built to be the best database layer, with branching, sharding, and zero downtime schema changes, but it is not the all in one backend. That makes it a stronger fit when an app outgrows simpler defaults, not when an AI assistant needs a fast first recommendation.

This also explains why Supabase grew so fast. AI coding tools like Bolt.new, Lovable, and Replit pushed more users into workflows where the winning backend is the one an LLM can provision quickly and explain simply. That distribution helped drive Supabase from about $30M ARR at the end of 2024 to $70M by August 2025.
The next leg is a fight to keep that default position as AI platforms add their own native databases and more specialized players chase production workloads. Supabase is moving deeper into analytics, observability, and AI specific storage, which pushes it from starter backend toward a broader application data platform.
