Conversation
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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

- 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.

Correct the Postgres version claim and add verification dates to time-sensitive data
The article claims Supabase offers "Postgres 17 on new projects," but official documentation shows Supabase currently uses PostgreSQL 15.x (15.1 in docs, 15.8.1 for self-hosted). Only Prisma Postgres runs PostgreSQL 17. Fix this factual error.
Additionally, all version numbers and quota rows (pricing, free-tier limits, auto-pause behavior) require an "as of " note. These numbers drift with platform updates and readers need to know when claims were last verified. Add a timestamp (e.g., "as of April 2026") and link to official docs so readers can check current values before publishing.
Applies to lines 30–39, 54–60, 69–69.

| Prisma Postgres was rebuilt around AI agents. A native MCP server ships with the Prisma CLI and works with Cursor, Claude Code, Windsurf, and the OpenAI Agents SDK. You can scaffold a schema and provision a database from a single prompt with `npx prisma init --db`. You can spin up a throwaway database for an AI-generated app with `npm create db` in seconds. See [Announcing Prisma's MCP Server](/blog/announcing-prisma-s-mcp-server-vibe-code-with-prisma-postgres) and [Prisma Postgres for AI Coding Agents](/blog/announcing-prisma-postgres-for-ai-coding-agents). | ||

🧩 Analysis chain
🌐 Web query:
What is the currently documented Prisma Postgres quickstart command for creating a new database? Check official Prisma docs/blog pages and confirm whether npm create dbandnpx create-db@latest are both valid, or if one is preferred/deprecated.
💡 Result:
The currently documented Prisma Postgres quickstart command for creating a new database is npx create-db@latest. This is shown consistently across official Prisma documentation pages, including the dedicated "Getting started with npx create-db" guide (result 1,6,7) and the Prisma Postgres quickstart (result 2). The command provisions a temporary Prisma Postgres database, providing a connection string for the .env file. npx create-db (without @latest) also appears in some quickstart pages (e.g., result 2,18,20), likely as shorthand since npx defaults to latest, but docs explicitly recommend @latest for ensuring the newest version without global install. npm create db is not documented in any official Prisma sources as a valid command for this purpose. No mentions found; it appears invalid or non-existent. Neither is deprecated; npx create-db@latest is the preferred/current command.

Replace npm create db with npx create-db@latest on line 149 for documentation accuracy
Line 149 references npm create db, but official Prisma documentation only supports npx create-db@latest. The npm create db command is not a valid Prisma-documented way to provision a database. Update line 149 to match the canonical command used elsewhere in the document (line 174) and align with the official Prisma Postgres quickstart.

…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.
