Most CMSes were designed around pages. Sanity was designed around content. When you are managing shared components, multiple audiences, or content that appears in more than one place, that difference shapes everything.
Bits&Letters designs and builds content systems with Sanity: the content model, a Studio shaped to how your editors work, the front-end, hosting, and integrations. Your team gets a CMS that fits the way they actually work.
David strikes that rare balance of design, creativity, and technical know-how, and made it easy for our team to move fast without sacrificing quality. He made the process of building and updating pages fun by creating templates and reusable components.

How we build with Sanity
Content modeling first
Before we write code, we map your content: what types exist, what repeats, what is shared. The model is the blueprint for the CMS and the front-end both.
A Studio your team will use
Custom editing interfaces with clear labels, validation, conditional fields, and role-based access. The interface matches your process, not the other way around.
Component-based page building
Editors assemble pages from a library of content blocks with live preview. Flexible enough for new layouts without a developer, structured enough that every combination looks right.
Migrations from WordPress and Webflow
Content audits, a new content model, migration scripts, and redirects. Most migrations are also the chance to clean up years of ad hoc updates.
Front-end in Astro or Next.js
Astro for content-driven marketing sites, Next.js when you need application-like features. Live preview works with both.
Training and post-launch support
Documentation and training for your team, with paid support scoped into the build and ongoing development agreed around your needs.
Built on Sanity
All case studiesLive Data Physical Installation w/ Sanity + SvelteKit
We built the backend for Stripe's viral Black Friday campaign — live data, clever animation, and enterprise-grade reliability.
Webflow to Astro + Sanity Migration
A component system and structured CMS that turned rigid pages into content the marketing team, and their agents, can actually change.
What's so great about Sanity?
Real-time collaboration
A Google Docs-style model where multiple editors work on the same document at once. Drafts are separate from published content, so updates do not touch the live site until they are ready.
Structured content
A product description, a team bio, or a pricing callout is defined once and referenced wherever it is needed. Update it in one place and every page reflects the change.
Complete customization
Custom workflows, validation rules, conditional fields, role-based access. We build exactly the editing experience your team needs.
Data portability
Sanity stores content as portable JSON. If you ever need to move, your content comes with you in a clean, structured format. It stays yours.
Sanity × AI
Put AI to work with content your whole team can use.
-
Your code. Your choice of support.
You own your code and can choose human or agent-assisted review, monitoring, and maintenance from B&L as your site evolves.
-
An agent-friendly foundation
Sanity’s structured content and MCP support give agents a clear way to work with your CMS. Paired with Astro or Next.js, your content and code are ready for human and AI collaboration.

Frequently asked questions about Sanity
What is Sanity CMS?
A headless content management system that stores content as structured data and delivers it via API. Unlike WordPress, Sanity separates content from presentation, so the same content can power a website, app, or newsletter from a single source.
How is Sanity different from WordPress?
WordPress tangles content with theme code, plugin data, and formatting markup. Sanity stores clean, structured JSON with real-time collaboration and a fully customizable editing interface. The tradeoff is more upfront design work; that's where we come in.
How much does a Sanity implementation cost?
We scope CMS implementation and the front-end together. Cost depends on your website's overall complexity, custom editing features, and integrations. We scope every project after a discovery conversation.
Can you migrate from WordPress to Sanity?
Yes. We audit existing content, design a new content model, write migration scripts, and build the new front-end. Migrations are also a good opportunity to restructure content that's accumulated over years of ad-hoc updates.
What front-end framework works best with Sanity?
We most often pair Sanity with Astro for content-driven marketing sites and Next.js for more interactive sites. Sanity's live preview works seamlessly with both.
Does Sanity support visual editing?
Yes. We implement component-based page building with live preview on every project. Editors see a form-based interface on one side and a real-time preview on the other.
How does Sanity handle multiple editors?
Real-time collaboration similar to Google Docs. Multiple editors can work on the same document simultaneously without overwriting each other.
What if we want to switch platforms later?
Sanity stores content as structured JSON, so it's portable. We also architect instances to be maintainable by any competent developer. Paid support is scoped into the build, with ongoing development agreed around your needs.
