our call
Start with ButterCMS — highest vibe code, weakest moat.
ButterCMS
ButterCMS provides hosted content infrastructure for non-technical marketers to manage pages and blog posts. If you already run a self-hosted headless backend like Payload CMS, Strapi, or Directus, paying $99-$375/month for ButterCMS is unnecessary. AI tools can generate custom content schemas and admin UI components in a matter of days.
you can rebuild
- Blog engine with built-in taxonomy (categories, tags, authors)
- Dynamic page builder components and landing page schemas
- Content collections for structured JSON data (e.g., FAQs, testimonials)
- Media library with CDN URL generation and basic image transformation
- Webhook triggers on content publishing and modification events
what you lose
- SaaS CDN infrastructure managed for content delivery
- Zero-config setup for non-technical marketing teams
- Pre-built multi-environment migration utilities out of the box
- Out-of-the-box user role permissions and audit logging
- Vendor technical support and guaranteed API uptime SLAs
real moats
- Developer ergonomics and client SDK availability across frameworks
- High switching costs once integrated across multiple legacy apps
- Zero infrastructure maintenance overhead for non-technical teams
open source escape hatches
- Payload CMS MIT
- Strapi Community (MIT / SEE LICENSE)
- Directus BSL 1.1 / GPLv3
Sanity
Rebuilding simple JSON storage with an admin UI is straightforward, but Sanity is a complex real-time document database with collaborative editing (OT/CRDT), custom GROQ query engine, and dynamic asset processing pipelines. Replacing its infrastructure from scratch introduces massive engineering overhead for zero commercial gain.
you can rebuild
- JSON document CRUD storage
- Basic draft vs. published state machine
- Simple webhooks on content change
- Role-based permission checks
- Form schema generation from code
what you lose
- Real-time collaborative document editing with conflict resolution
- GROQ dynamic query language with deep references
- Sanity Image Pipeline (instant focal point cropping and resizing on CDN)
- Server-Sent Events (SSE) live content preview streams
- Sanity Studio customizable React editorial UI framework
