Sanity to Payload CMS Migration

Why Teams Are Leaving Sanity for Payload CMS

Sanity's a solid headless CMS — until it isn't. As projects scale, the cracks show up fast. Pricing gets unpredictable. GROQ, for all its flexibility, locks your querying logic into a proprietary syntax nobody else uses. And the moment you need custom backend logic — webhooks, access control, custom endpoints — you're suddenly stitching together serverless functions and third-party services just to get basic things done.

Payload CMS takes the opposite approach. It's open-source, self-hosted, and built on Node.js with MongoDB or Postgres. One codebase you actually own, with a full admin panel, a solid API, and complete control over your data layer.

We've migrated editorial teams, SaaS platforms, and e-commerce brands from Sanity to Payload. Here's what that process actually looks like.

The Real Pain Points with Sanity

Pricing That Scales Against You

Sanity's free tier works great for prototypes. Hit production traffic and it's a different story — API CDN requests, dataset usage, and bandwidth charges stack up quickly. A mid-traffic content site can blow past $99/month without much effort. Payload's self-hosted model ties costs to your infrastructure, not per-API-call metering.

GROQ Lock-In

GROQ is Sanity's proprietary query language. Flexible? Yes. Portable? Not at all. Every query you write is a query you can't reuse anywhere else. Switch CMSes later and you're rewriting your entire data-fetching layer from scratch. Payload uses standard REST and GraphQL — no proprietary syntax, no lock-in.

Limited Backend Customization

Need custom auth flows? Role-based access that goes beyond basic permissions? Server-side logic triggered by content changes? In Sanity, you bolt on external services. In Payload, hooks, access control, and custom endpoints are first-class features baked directly into the CMS.

No Native Database Access

Sanity stores your data in their hosted Content Lake. You can export it, sure, but direct database access isn't part of the deal. With Payload, your MongoDB or Postgres database is yours. Query it directly, back it up on your own schedule, replicate it however you want.

Studio Customization Ceiling

Sanity Studio is React-based and reasonably customizable — but you're working inside their plugin architecture and structure API. Payload's admin panel is also React-based, except you own the entire application. The customization ceiling is effectively gone.

What Payload CMS Brings to the Table

Self-Hosted, Open-Source Freedom

Payload is MIT-licensed. Deploy it anywhere that runs Node.js — Railway, Render, DigitalOcean, AWS, your own VPS. No vendor lock-in, no surprise invoices at the end of the month.

TypeScript-First Architecture

Payload's built in TypeScript from the ground up. Collection configs generate types automatically. Your frontend and backend share the same type definitions. That alone kills entire categories of bugs.

Built-In Access Control and Auth

Authentication, role-based access control, field-level permissions — all included out of the box. No external auth service required. Define who can read, create, update, or delete at the collection or field level using straightforward functions.

Hooks for Everything

Before and after hooks on every CRUD operation. Need to send an email when a post publishes? Resize an image on upload? Sync data to a third-party API? Write a hook. It's just Node.js — no serverless glue code needed.

Rich Text Done Right

Payload's Lexical-based rich text editor stores content as structured JSON, not HTML strings. You get full control over serialization, custom blocks, and inline elements. It's comparable to Sanity's Portable Text, but it lives inside your own application.

Our Sanity to Payload Migration Process

1. Content Audit and Schema Mapping

We export your Sanity schemas and map every document type, object type, and reference to equivalent Payload collections and globals. We identify Portable Text blocks that'll need custom serializers in Payload's rich text config.

2. Data Export and Transformation

We pull your full dataset from Sanity using their export API. Custom scripts transform those NDJSON exports into Payload-compatible documents, preserving relationships, slugs, and metadata along the way. Images and files migrate to your chosen storage — local filesystem, S3, or Cloudflare R2.

3. Payload Configuration Build

We build your Payload config with TypeScript collection definitions, access control policies, hooks, and custom components. Had customizations in Sanity Studio? We replicate that functionality in Payload's admin panel.

4. API Layer and Frontend Integration

Whether you're on Next.js, Astro, or something else, we update your data-fetching layer. GROQ queries get replaced with REST or GraphQL calls against your Payload API. We use Payload's auto-generated TypeScript types for end-to-end type safety.

5. SEO Preservation

Every URL, every redirect, every meta tag — preserved. We map Sanity slugs to Payload slug fields, configure 301 redirects for any structural URL changes, and validate your sitemap and canonical tags post-migration. Screaming Frog crawls run before and after to catch any gaps.

6. QA, Training, and Launch

Full regression testing on content rendering, admin workflows, and API responses. We train your editorial team on Payload's admin interface. Then we cut over with zero downtime.

SEO Preservation Strategy

SEO migration is where most agencies drop the ball. Here's how we handle it:

• Pre-migration crawl captures every indexed URL, meta tag, structured data block, and internal link
• Slug parity — every content piece keeps its exact URL path
• 301 redirect map for any URLs that must change due to structural differences
• Canonical tag audit post-launch to prevent duplicate content issues
• Google Search Console monitoring for 90 days after launch to catch crawl errors and indexing drops
• Structured data validation — JSON-LD schemas are ported and tested against Google's Rich Results tool

Timeline and Pricing

A typical Sanity to Payload migration takes 3-6 weeks depending on content volume and customization complexity.

Project Size	Content Volume	Timeline	Starting Price
Small	Under 500 documents	2-3 weeks	$4,000
Medium	500-5,000 documents	3-5 weeks	$8,000
Large/Enterprise	5,000+ documents	5-8 weeks	$15,000+

Pricing covers schema mapping, data migration, Payload configuration, frontend integration, SEO preservation, and editorial team training. Complex custom plugins, multi-tenant setups, or extensive access control systems get scoped separately.

Is Payload CMS Right for You?

Payload's the strongest choice if your team cares about ownership, TypeScript, and backend flexibility. If you want a CMS that doubles as your application server — not just a content API bolted on the side — Payload's the move.
