Sanity CMS Development
We design and build content management systems with Sanity. Content modeling, custom editing interfaces, front-end integration, and hosting.
Our Services
Your new favorite design & dev partner
The list below is heavy on frameworks, tech stacks, and platforms, but we don't want you to think of Bits&Letters as just a dev shop. We can help you figure out what you need, whether it's improving your existing design or SEO, migrating you onto something easier to maintain, or building a brand new site or app.
We fix the system underneath
Most redesigns stop at the visual layer. We work on the content model, CMS workflow, component architecture, and front-end together, so the site stays useful after launch.
Built for the people who update it
Your team should be able to publish, revise, and create new pages without filing tickets for every change. We design the CMS and components around real editorial workflows.
AI-ready code your team can keep editing
We build with Claude Code and other agents in mind, so we can move faster without sacrificing quality, and your team can use your favorite tools to make changes after handoff.
Small teams, direct access
Every client gets a shared Slack channel and Notion workspace, with direct access to the folks working on your design and code — no middle-people or ticket queues.
Astro Web Development
Content-driven marketing websites built with Astro. Front-end, CMS, hosting, and integrations handled as one system by a single experienced partner.
Next.js Development
Web applications and content-driven sites built with Next.js. Front-end, CMS, hosting, and integrations handled as one system.
Design Systems
Components, patterns, and documentation that connect brand design to web implementation so your team can produce pages without starting from scratch.
WordPress Development
WordPress development and rebuilds for companies with complex content needs. Custom themes, clean architecture, or migration to a headless CMS.
If you need help with something specific that's not listed here, shoot us an email — these solutions are our top recommendations, but we've worked with pretty much everything.
How we do what we do
Start with discovery
Whether it's just some quick Q&A at the start of the engagement, or a full workshop with your team, we aim to deeply understand your goals and constraints, so we can deliver solutions that'll stand the test of time.
Design ⇔ code
Handoffs. You hate 'em, right? Us too. Most of our design process happens in code, either in live prototypes or iterations on beta versions of your site, and we demo working software, not just mockups.
Human craft with AI speed
Clients hire companies like ours for our judgment and experience — precisely the stuff you can't get from AI.
But that expertise includes deep, hands-on familiarity with the AI ecosystem, from using agent fleets to assist with scaffolding and writing boilerplate code, to integrating LLMs, skills, and other tools into client workflows
Structured content specialists
We're experts in getting you and your team off of the page-building treadmill, building content systems that keep your website organized and maintainable, so you can keep moving.
A structured, headless approach also helps set you up for reuse across digital channels — if that's something you need now or in the future — and also makes future migrations or bulk edits much simpler.
Training & documentation
We set you up for success with live workshop sessions, video demos, and written docs, all tailored to your key workflows and business needs. And if you have questions about your setup, we're just an email or Slack message away.
Your codebase, built to last
The code we ship is yours, and it's written so another developer (yours or someone else's) can pick it up without a translator. No walled gardens, agency lock-in, or gnarly surprises in year three.
Engagements
Every design + dev package includes code ownership, technical SEO and accessibility fundamentals, and a dedicated Slack and Notion workspace with direct access to our team.
