What our research says

Keel Studio

Keel Studio's premise is narrowing the gap between 'operator wants a new field' and a deployed change, without going through a formal dev cycle each time. It sits inside a larger custom-built operations platform rather than standing alone, so evaluating it means going through Keel's discovery-call sales process rather than a self-serve trial.

Pros

  • Backed by a named UK company (Planko Ltd) rather than an anonymous storefront
  • Targets a specific, well-defined gap — operator self-service inside a custom backend
  • Base Keel platform already covers database, APIs, auth, and permissions, so Studio changes plug into a real system

Cons

  • No published pricing — every engagement starts with a discovery call and a custom quote
  • No free tier or self-serve trial to test before committing to a build

Supabase

Supabase is a strong default for developers who want a real Postgres database with auth and storage included, and it is especially popular as the backend for AI-generated apps. The free tier is enough to build and demo. Watch the pausing of idle free projects and usage-based add-ons once you go to production.

Pros

  • Standard Postgres with auto-generated APIs and Row Level Security
  • Open source core that can be self-hosted
  • Auth, storage, realtime and functions in one project
  • Spend caps are on by default on the Pro plan

Cons

  • Free projects are paused after a week of inactivity
  • Pro costs are per organization and compute for additional projects is billed on top
  • Vector search at large scale is less specialised than a dedicated vector database

Which one fits

Choose Keel Studio if you need

  • Operations teams already running (or considering) Keel who want minor changes self-served
  • Companies replacing a rigid, template-locked ERP with something built to their own process

Choose Supabase if you need

  • Developers and vibe-coders who need a ready backend with auth for a web or mobile app
  • AI apps that want embeddings stored beside application data in Postgres
