# supabase-skill vs planetscale-skills

Pick supabase-skill if you are on Postgres and want the agent to write row-level-security-correct queries, auth, and realtime by default. Pick planetscale-skills if you are on MySQL and want schema changes to behave like Git — branch, deploy-request, merge — without downtime at scale.

## Pick supabase-skill when

Your stack is Postgres (or Supabase), and RLS policies, auth flows, edge functions, and realtime are where you want the agent to stop making mistakes.

## Pick planetscale-skills when

Your stack is MySQL at scale, and you want branch-based, zero-downtime schema migrations with a deploy-request workflow.

## Side by side

| | supabase-skill | planetscale-skills |
| --- | --- | --- |
| Database engine | Postgres | MySQL / Vitess |
| Signature strength | Row-level security, auth, realtime, edge functions | Schema branching, deploy requests, online migrations |
| Migration model | Standard migrations, RLS-aware | Git-style branch / deploy-request / merge |
| Scale approach | Managed Postgres | Horizontal Vitess sharding |
| Publisher | Supabase (official) | PlanetScale (official) |
| Provenance | Verified | Verified |

## Bottom line

The choice follows your database, not the skill. If you already run Postgres or Supabase, supabase-skill removes the most common footguns — views bypassing RLS, updates silently returning zero rows — and knows auth and realtime. If you run MySQL on PlanetScale, planetscale-skills makes migrations reviewable and safe with the branch-and-deploy-request flow. Neither replaces the other; pick the one that matches the engine you are committed to.

## Common questions

**Should I use the Supabase or PlanetScale skill?**

Match your database. supabase-skill is for Postgres/Supabase and is strongest on row-level security, auth, and realtime. planetscale-skills is for MySQL on PlanetScale and is strongest on Git-style schema branching and zero-downtime migrations. Both are official, vendor-published, verified skills.

**Is Supabase or PlanetScale better for schema migrations?**

It depends on the model you want. planetscale-skills brings a branch / deploy-request / merge workflow that makes schema changes reviewable and non-blocking on MySQL. supabase-skill handles standard Postgres migrations and, crucially, keeps them row-level-security-aware. If Git-like migration branching is the priority, PlanetScale; if RLS-correctness is, Supabase.

**Do these skills work outside Claude Code?**

We list only verified-working agents on each skill page. supabase-skill is catalogued for Claude Code, Cursor, and Codex; planetscale-skills for Claude Code and Cursor. Check each skill page for the current list.
