Summary

  • New blog post at apps/blog/content/blog/supabase-vs-prisma-postgres/index.mdx comparing Supabase and Prisma Postgres as database services, with a fair acknowledgement of Supabase's broader BaaS up front.
  • Covers architecture (unikernels vs. dedicated instances), pricing models (ops vs. compute), DX (ORM integration, code sample comparison), migrations, Query Insights, pooling/edge, Studio, and AI/MCP integration.
  • Ends with a when to pick which table and a clear CTA toward Prisma Postgres.

Assets

  • hero-supabase-vs-prisma-postgres-844x474.svg and meta-supabase-vs-prisma-postgres-1266x711.png are placeholders. The meta PNG is a copy of an existing post's OG image so the share preview will look wrong. Both should be swapped for final art from the design team before merge.

Test plan

  • pnpm exec fumadocs-mdx compiles the new post with no errors.
  • Local pnpm dev --filter blog serves the post at http://localhost:3002/blog/supabase-vs-prisma-postgres returning HTTP 200.
  • All 11 H2 sections render (verified via rendered HTML).
  • No em dashes, en dashes, or ellipses in prose (per style guide).
  • Tags match the allowed enum (prisma-postgres, data-platform).
  • Final hero and meta images from design team.
  • Review pass from a DevRel teammate.

Summary by CodeRabbit

  • Documentation
    • Published a new in-depth blog post comparing Supabase and Prisma Postgres. Includes a snapshot comparison table, sections on architecture, cold-starts, pricing/free tiers, developer experience with ORM/schema/query examples, migrations, query diagnostics/observability (with embedded visuals), connection pooling/edge considerations, studio/data browsing, AI/agent integration, decision guidance, and a CLI snippet to try Prisma Postgres.

Adds a balanced, database-layer-focused comparison between Supabase and
Prisma Postgres. Covers architecture, pricing models, DX, migrations,
Query Insights, pooling, Studio, and AI/MCP integration, with a clear
"when to pick which" framing.

Hero and meta images are placeholders and should be swapped for final
art before merge.

In `@apps/blog/content/blog/supabase-vs-prisma-postgres/index.mdx`:
- Around line 9-10: The frontmatter fields metaImagePath and heroImagePath
currently reference placeholder artwork; update those two keys in the blog post
frontmatter (metaImagePath and heroImagePath) to point to the final, correct
image files (ensure the target image filenames/paths exist in the repository and
match the intended social preview and hero art), then verify the meta preview by
building or using the share-preview tool to confirm the social card displays the
correct image.
- Around line 149-150: The doc currently uses the incorrect command `npm create
db` in the Prisma Postgres paragraph; replace that token with the canonical `npx
create-db@latest` so the sentence reads consistently with other references (see
the surrounding text that mentions `npx prisma init --db` and the later `npx
create-db@latest` usage) and align with the official Prisma Postgres quickstart.
- Around line 30-39: Update the "**Postgres version**" table row to correctly
state Supabase uses "PostgreSQL 15.x" (Prisma Postgres runs PostgreSQL 17), and
add a verification timestamp (e.g., "as of April 20, 2026") to all
time-sensitive table rows: "**Postgres version**", "**Pricing model**", "**Free
tier**", and "**Cold starts**"; also add inline or footnote links to the
official Supabase docs, Prisma docs, and respective pricing pages so readers can
verify current values before publishing.

…ormat

- Drop the verbose scope-setting intro paragraphs.
- Reorder the snapshot table so the five Prisma advantages (cold starts,
  pricing model, free tier, query diagnostics, AI/MCP) come first with
  bolded cells, and baseline rows follow.
- Remove all Drizzle mentions and all references to Accelerate.
- Trim architecture, migrations, query insights, and connection pooling
  sections.
- Pricing: add a small-startup example that favors Prisma, drop the
  read-heavy caveat.
- DX: shorter, more confident framing around the Prisma ORM package.
- Remove the dated Why-Prisma-2024 link.
- Query Insights: add the dashboard GIF and link to the announcement post.
- Studio: list each product's strengths without declaring a winner.

- Add shared OG/hero art and wire metaImagePath and heroImagePath
- Improve readability: callouts, bullets, internal link basePath fixes
- Update title to avoid Next.js ambiguity; trim closing section

Made-with: Cursor
Replace `npm create db` with the canonical `npx create-db@latest` to match
other references in the post and the official Prisma Postgres quickstart.

Made-with: Cursor
Contractions pass, cut AI-pattern trailing clauses, and tighten the closing recommendation.
