Honest Fit Assessment
We tell you when Svelte is the wrong choice, before you spend money on it.

We build and migrate web applications with Svelte and SvelteKit for teams that need quick load times, less JavaScript in the browser, and code their own engineers can maintain.
Introduction
Svelte suits products where load speed and a small code footprint matter more than access to the biggest library ecosystem. It compiles components into plain JavaScript at build time, so the browser downloads less code and does less work.
That is the usual pitch. Our view is narrower. Svelte pays off most for dashboards, content heavy sites, embedded widgets and customer portals used on mobile networks. For a product that depends on dozens of React only libraries, a rewrite can cost more than it returns, and we will say so before any work starts.
As a software product development company, we put every request through our Svelte Fit Check. We look at who uses the app and on which devices, which libraries you depend on, and who will maintain the code after launch. Only then do we recommend a build, a migration, or no change at all.
Svelte and SvelteKit builds with server rendering for fast first loads
Phased migration from React, Vue or Angular, one route at a time
Code reviews and handover so your team can own the codebase
Security and Compliance
Security work on a Svelte project is mostly about the server side. We follow the HIPAA, ISO 27001 and SOC 2 controls shown below, which in practice means validating input in SvelteKit server endpoints, setting strict content security policies, scanning dependencies in the build pipeline, and checking roles on every protected route. Projects that handle health or payment data get a security review before each major release.
Svelte Services
We build new web applications in Svelte and SvelteKit, from first prototype to production release. Typical projects include customer portals, booking flows, internal dashboards and marketing sites that need app like interaction.
Each build starts with a short technical discovery. We agree on routing, data loading, rendering mode and hosting before writing components, because those early choices decide how fast the app stays as it grows.

Why Pattem Digital
We tell you when Svelte is the wrong choice, before you spend money on it.
Every project reports bundle size and Core Web Vitals before and after release.
Work ships in small releases, so you see progress every sprint.
Clear conventions, tests and documentation make handover simple.
Our engineers handle APIs, databases and cloud hosting alongside the front end.
Start with an audit or a small team, then scale as the product grows.
Svelte Full Stack
Svelte handles the interface. The rest of the stack decides how data flows, how the app scales and what hosting costs. We choose back end tools based on your team's skills and expected load, not on what is fashionable. These are combinations our engineers use in production work.

Suits products with many related data types, where each screen should request only the fields it needs.

A simple, widely understood setup for teams that already run REST services and want a lighter front end.

A structured option for larger teams that want typed GraphQL contracts and a modular Node.js back end.

Good for real time features such as live updates and chat, with Node.js handling custom business logic.

Chosen when the API must handle many concurrent requests with low memory use.

A quick path to production for data products, with Postgres from Supabase and Python services in FastAPI.

Generates a GraphQL API from your Postgres schema, which shortens back end work for data heavy dashboards.

A serverless setup where you pay for actual use, suited to traffic that rises and falls sharply.
Engineering Standards
Our Svelte projects follow one set of conventions for component structure, naming, state and data loading. Every pull request gets a peer review and runs automated tests before it merges. We keep dependencies few and current. Documentation is written during the work, not at the end.

Shared rules for components, stores and routes make any file easy to find and change.
Unit, component and end to end tests run on every change.
Components are built for reuse, so new screens take less time to ship.
Setup guides, architecture notes and component docs stay in the repository with the code.
Svelte Developers
Add Svelte engineers to your team or hand us a complete project. We agree on scope, communication rhythm and quality checks at the start, then report progress every sprint.
Svelte engineers work inside your sprints, on your tools and your code review rules.
We build and run a Svelte team for you, then transfer it to your organization when you are ready.

Common Queries

Got more questions? Feel free to contact us directly with any questions.
Cost depends on scope, team size and the engagement model. An audit or proof of concept is priced as a fixed package, while a full product build is usually priced by team and duration. We share a written estimate after a short discovery call.
Choose Svelte when page weight, load speed and a simpler codebase matter most. Choose React when you rely on its large library ecosystem or already have a big React team. We recommend one only after looking at your product.
In most cases, yes. We migrate route by route, so the current app keeps running while new screens move to Svelte. Each step is tested and can be rolled back if needed.
Most engagements begin with a discovery session soon after agreement.
Yes. Most of our Svelte projects use SvelteKit for routing, server rendering and API endpoints. For installable apps we draw on our progressive web app development work. We also build plain Svelte components when you need widgets inside an existing site.
You do. The repository, documentation and deployment setup belong to you, and we run a handover so your team can maintain the app without us.
