Svelte developers on your backlog
Developers who pick up tickets, follow your branching rules, and ship in reviewed pull requests.
The Problem
You Picked Svelte, and Now Nobody Else Knows It
It shows up when the developer who chose Svelte gets busy or leaves. The app works, but nobody else can extend it, and job posts draw no Svelte applicants.
01 · Syntax
Half the components use old syntax, half use runes.
We move components to Svelte 5 runes as we touch them, with tests.
02 · Forms
Forms fail when JavaScript loads slowly or not at all.
We build forms as SvelteKit form actions, then enhance them with use:enhance.
03 · Tests
There are no tests, so every release goes out on hope.
We add unit, component, and end-to-end tests to every change we ship.
04 · People
Only one developer on the team knows Svelte.
We share the load and document patterns your next hire can follow.
Your product runs on SvelteKit because one developer loved it, and the app is fast. Now that developer is stretched thin, and your job posts bring in React resumes. Half the components use Svelte 4 syntax, the other half use runes, and nobody's sure which is right. Forms break when JavaScript loads slowly on a weak connection. There are no tests, so every release goes out on hope.
We start with a code review: Svelte version, component patterns, load functions, and the adapter you deploy with. Then our developers join your repository, ship features in reviewed pull requests, and move components to Svelte 5 runes as we touch them. Forms become SvelteKit form actions that work before JavaScript loads. Every change ships with tests, so the next developer inherits a map, not a mystery.
Runes, one component at a time
Components move to Svelte 5 runes as we touch them, with no big-bang rewrite.
Forms that work without JavaScript
SvelteKit form actions post on any connection, then use:enhance adds the smooth version.
Three test layers
Vitest, Svelte Testing Library, and Playwright tests on every change we ship.
Our Svelte and SvelteKit Development Process
From Code Review to Handover in Five Clear Steps
You see our findings and a fixed price first, then working screens on preview deploys and tested pull requests every week.
We read your svelte.config, routes, and load functions, and run the Svelte 5 migration tool on a branch to see what changes. You get the findings and the plan that fits your backlog.
What's Included
What You Get With Svelte Development Services
Svelte developers who leave the codebase easier to work in: features, a runes migration, progressive forms, typed data loading, three test layers, and docs.
Compare Options
DeveloperLook vs Freelancer vs Rewrite in React
A freelancer can start within days, and a React rewrite widens your hiring pool. Here's what each one costs you when your app already runs on SvelteKit.
| Feature | DeveloperLookBest fit | Freelancer | Rewrite in React |
|---|---|---|---|
| Time to first change | About 1 week | A few days | Months before parity |
| Svelte 5 runes | Migrated as we go | Depends on the person | Not relevant |
| Hiring pool later | Docs make it wider | Unchanged | Largest pool |
| Forms without JavaScript | Form actions everywhere | Varies by person | Rebuilt from scratch |
| Tests | 3 layers on every change | Often none | Written again |
| Bundle size | Stays small | Stays small | Often larger |
| Cost | Fixed price per scope | Lowest hourly rate | Highest, a full rebuild |
| Ownership | Your repository, documented | Yours, per contract | Yours, after the rewrite |

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built apps, dashboards, and websites for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Teams Find Svelte Developers Through Us
Svelte is easy to read and hard to hire for. These habits make sure the next person can pick up exactly where we stop.
Patterns written down
We document how your app loads data, handles forms, and shares state. Your next hire learns your patterns in days, not by trial and error.
Runes without a freeze
We migrate components as we touch them, so features keep shipping. Old syntax that still works can wait for a calmer sprint.
Slow networks in mind
We test forms and pages with JavaScript throttled or switched off. Customers on weak connections can still sign in and submit.
Honest about React
If your hiring plans depend on a big talent pool, we'll tell you before we quote that React may suit you better. We won't push Svelte for its own sake.
Two sets of eyes
A second engineer reviews every pull request before your team sees it. Svelte's short syntax still hides the occasional logic mistake.
Your code, your accounts
Repository, hosting, and database accounts stay in your name from day one. You can remove our access whenever you choose.

Good fit
Teams whose Svelte expert left
Your SvelteKit app was built by one developer who has moved on, and you need to hire Svelte developers who can pick it up fast.
Startups that chose SvelteKit
You picked SvelteKit for speed and want SvelteKit developers to build the next screens while your founders focus on sales.
Teams still on Svelte 4
Your app still uses Svelte 4 syntax, and you want the move to runes done without stopping feature work for weeks.
Companies hiring for a Svelte role
You've tried to find Svelte developers through job boards for months, and you need someone shipping while the search continues.
Agencies with Svelte client work
You've sold Svelte web development to a client and need developers who deliver it under your agency's name and standards.
Not a fit
No code, no preference
You have no code yet and no team preference. React Development Services may suit your long-term hiring plans better.
Content site, not an app
You need a marketing site or blog more than an app. Our Astro Website Development page covers content-first sites.
Budget under $950
You need a single component fixed in an afternoon. A freelancer paid by the hour is cheaper for that than our smallest plan.
Native mobile app needed
You need an iOS and Android app with offline storage and push alerts. A mobile framework fits that better than a SvelteKit web app.

Saimul IslamFounder & CEO, DeveloperLookStill have questions?
Send a message or book a call with the team.
Svelte work with DeveloperLook starts at $950 for a feature sprint of up to 4 features or a batch of fixes. A SvelteKit app or dashboard of up to 12 screens costs $3,200, and a full product build of up to 25 screens starts at $6,600. Prices are fixed after a free code review.
A sprint takes about 2 weeks, a 12-screen app or dashboard 5 to 8 weeks, and a larger product 10 to 12 weeks. The main variables are how many APIs the app talks to and how settled your designs are. You see working screens on preview deploys from the first sprint.
You can hire SvelteKit developers through freelance sites, the Svelte community's job channels, or a development company like ours. The pool is smaller than React's, so a full-time search often takes months. If you want to hire Svelte.js developers for a short run of work, a scoped sprint is the quickest start.
Yes. Svelte 5's runes make state explicit, which helps as an app grows, and SvelteKit adds routing, data loading, and server code. The bigger risk in a large Svelte app is hiring, not performance, so we document patterns as we build and keep tests on every change.
Svelte 5, released in October 2024, introduced runes: $state, $derived, $effect, and $props replace the older reactive syntax. Runes make reactivity explicit and work in .svelte.js files too. Svelte 5 still runs most Svelte 4 components, so you can migrate gradually instead of all at once.
We migrate component by component. The official tool, run with npx sv migrate svelte-5, converts most syntax automatically, and we fix the rest by hand. Because old and new syntax can live side by side, your features keep shipping while the migration happens in the background.
Yes, when they're built as form actions. The form posts to the server like a classic HTML form, so it works on slow connections or when scripts fail. Adding use:enhance then gives the smooth, no-reload version on top. We build every form this way unless there's a reason not to.
Almost anywhere, through adapters. SvelteKit has official adapters for Node.js servers, static hosting, Vercel, Netlify, and Cloudflare, so the same code can move between hosts. We pick the adapter by your traffic, your budget, and whether your pages need a server at all. Static hosting suits sites with no server logic and is usually the cheapest option.
Rich Harris created Svelte and released it in November 2016, and it's open source under the MIT license. He joined Vercel in 2021 to work on Svelte full time, and a core team of maintainers runs the project. That backing is one reason Svelte development is a safe long-term choice.
You do. Your repository, hosting, and database stay in your name, and you can cut our access at any time. At handover, you get component patterns, deploy notes, and a list of any Svelte 4 syntax left in place. Your plan covers fixes and small changes for 30 to 90 days.
