On public evidence, the best SvelteKit agencies right now are Mainmatter, which employs a Svelte core team member, and Okupter, a one-person SvelteKit studio with a published price. After those two, the evidence thins out fast. Most firms at the top of Clutch’s Svelte category show no Svelte project we could find.
We wrote this guide, so weigh that. We left ourselves out of the ranking. Where we fit is in a box at the end.
Who this is for: a business that has picked Svelte or SvelteKit, or is leaning that way, and needs an outside team. Who should look elsewhere: if you haven’t picked a framework yet, the pool of React and Next.js agencies is far bigger. See our Next.js agency list and our comparison of Svelte 5 runes and React hooks.
Why Svelte share is the first thing we checked
Svelte is a small category, and agencies know buyers search for it. So many firms list Svelte next to six other frameworks. We read the pages that rank for “best Svelte development company”: Clutch’s Svelte category, the DevsData list, GoodFirms, and SelectedFirms. DevsData ranks itself first and names no Svelte project of its own. Clutch notes that it “may earn a fee for some placements”.
So for each agency we counted the work we could open, and how much of it names Svelte or SvelteKit. Where the agency declares a Svelte share on Clutch, we put that number next to ours.
| Agency | What we counted | Names Svelte | Share | Svelte share declared on Clutch |
|---|---|---|---|---|
| Okupter | Named projects and client testimonials on its homepage | 4 of 14 | 29% | No Clutch profile |
| Mainmatter | Client entries on its work page | 4 of 48 | 8% | Not listed |
| Wonder Makers | Clutch reviews | 1 of 12 | 8% | 15% |
| Dipa Inhouse | Clutch reviews | 0 of 27 | 0% | 10% |
| Sketch Development | Clutch reviews | 0 of 23 | 0% | 10% |
| Notix | Clutch reviews | 0 of 13 | 0% | 30% |
| Increasio | Portfolio projects | 0 of 13 | 0% | 10% |
Counted 2026-10-14. Clutch pages were sometimes cut off when we read them, so a later review could mention Svelte. If you run one of these firms and we missed a Svelte project, send the link.
How we scored them
Each agency gets 0, 1, or 2 points on five criteria, for a total out of 10. We only counted what we could open on a public page. A low score means we found little public evidence. It doesn’t mean the work is bad.
| Criterion | 2 points | 1 point | 0 points |
|---|---|---|---|
| Svelte share of work | Half or more of the work we could check names Svelte | 10% to 49% | Under 10% |
| Named Svelte projects | 3 or more named projects, client or own, that use Svelte | 1 or 2 | None |
| Community depth | Maintains Svelte or runs a major Svelte community project | Public Svelte writing, a course, or talks | Nothing found |
| Budget shown | A price on the agency’s own site | A minimum or package price on Clutch | Nothing found |
| Independent reviews | 10 or more on Clutch or a similar platform | 1 to 9 | None found |
Ties are ordered by named client work, then by review count.

1. Mainmatter: best for a serious SvelteKit build with expert review
- Share (0): 4 of the 48 clients on their work page name Svelte. Most of their work is Ember.js (21 entries) and Rust (8). Svelte is newer for them, not their main line.
- Projects (2): four named Svelte clients: Rillet, Morphic (“Svelte 5 upgrade”), Copley, and Rail Europe, where they started “building a new B2C offering using Svelte and SvelteKit” (case study).
- Community (2): their Svelte page says “Our team is led by Paolo Ricciuti, Svelte maintainer and co-author of SvelteLab.” They also say they co-organize Svelte Summit.
- Budget (1): $10,000+ minimum on Clutch, $100 to $149 an hour.
- Reviews (2): 4.8 from 12 reviews on Clutch, based in Munich. One review, from a travel company, names Svelte and SvelteKit.
Pick them when you want people who work on Svelte itself to design or review your app. They’re the only firm here with a core team member on staff.
2. Okupter: best for a small SvelteKit app at a known price
- Share (1): on okupter.com, 2 of 14 named projects are stated SvelteKit builds, and 2 client testimonials are about Svelte work. The rest don’t name a stack. The studio presents itself as SvelteKit only, and its own site runs on SvelteKit, so the real share is likely higher than we could count.
- Projects (2): Cyfrin Updraft (“SvelteKit frontend”, “100K+ monthly users” by Okupter’s count), WhatIsThatBook (“SvelteKit and AI”), and auth work for Lefroy Brooks, whose owner says Justin “knows Svelte/kit inside out”. When we loaded updraft.cyfrin.io on 2026-10-14, its homepage served Next.js files, so that site may have changed since. whatisthatbook.com served SvelteKit files.
- Community (1): a SvelteKit course and a blog with posts on Svelte 5 migration and SvelteKit auth.
- Budget (2): the clearest prices on this list: “$6,000 per two-week sprint”, “$149” per consulting session, and “$349” per month for async help (checked 2026-10-14).
- Reviews (0): we found no Clutch profile. The site has client testimonials, but they aren’t on an independent platform.
Pick Okupter for an MVP or a focused feature where one senior SvelteKit engineer is enough. It’s a one-person studio, so plan for holidays and for what happens after handover.
3. Wonder Makers: best for a visual, animated site with a SvelteKit tool inside
- Share (0): 1 of 12 Clutch reviews names Svelte. They declare 15% Svelte on Clutch. Their own site runs on Astro.
- Projects (1): a Clutch review from Revolgy describes a “Full-stack build (SvelteKit + PocketBase)” for an AI cloud assessment tool. Their homepage lists Revolgy among seven projects.
- Community (0): nothing found.
- Budget (1): $25,000+ minimum on Clutch, $100 to $149 an hour.
- Reviews (2): 5.0 from 12 reviews on Clutch, based in Prague.
Pick them when design and motion matter as much as the code. Their portfolio leans to immersive and game sites.
4. Dipa Inhouse: best for low-cost design and front-end work
- Share (0): 0 of 27 Clutch reviews name Svelte. They declare 10% Svelte and 20% Next.js on Clutch.
- Projects (0): none found. Their reviews mostly name Figma and Webflow.
- Community (0): nothing found.
- Budget (1): $5,000+ minimum on Clutch, $25 to $49 an hour, the lowest rate here.
- Reviews (2): 4.9 from 27 reviews on Clutch, based in Malang, Indonesia.
Pick them for UI design and front-end work on a tight budget. Ask for a Svelte sample before you assume Svelte depth.
5. Sketch Development: best for custom software with AI work
- Share (0): 0 of 23 Clutch reviews name Svelte. They declare Svelte at 10%, alongside eight other frameworks at 10% each, on Clutch.
- Projects (0): none found. The frameworks named in reviews include React.
- Community (0): nothing found.
- Budget (1): $10,000+ minimum, $150 to $199 an hour, the highest rate here.
- Reviews (2): 5.0 from 23 reviews on Clutch, based in Missouri. They rank first in Clutch’s Svelte category.
Pick them for US-based custom software and AI work. Their place at the top of the Svelte category comes from their reviews, not from Svelte work we could see.
6. Notix: best for React Native apps, with Svelte on the side
- Share (0): 0 of 13 unique Clutch reviews name Svelte, though they declare 30% Svelte and 70% React Native on Clutch.
- Projects (0): none found.
- Community (0): nothing found.
- Budget (1): $10,000+ minimum, $50 to $99 an hour.
- Reviews (2): 5.0 from 14 reviews on Clutch. Belgrade, Serbia, and Wyoming.
Pick them for a mobile app. If Svelte matters, ask them to show it.
7. Increasio: claims the most Svelte, shows the least
- Share (0): their Svelte page claims “30+ Svelte projects”, but none of the 13 projects on their portfolio names Svelte. Several name Next.js or Gatsby, and their own site runs on Next.js.
- Projects (0): none found.
- Community (0): nothing found.
- Budget (1): Clutch lists packages from $1,990, with a $5,000+ minimum.
- Reviews (0): no reviews on Clutch.
They appear on several “best Svelte” lists. We couldn’t confirm the Svelte work behind that.
Checked and left off
- DevsData ranks itself first on its own Svelte list and names no Svelte project of its own.
- Other firms in Clutch’s Svelte category, such as iConcept, Cruxlab, and Lifted Solutions, list Svelte among many services. We didn’t score them, because their profiles showed no Svelte detail beyond the listing.
How to choose a Svelte development company
- Ask for a SvelteKit app you can open. Then check it yourself: a SvelteKit site loads files from
/_app/immutable/. If you see/_next/, it’s Next.js. - Ask whether they’ve shipped Svelte 5. Svelte 5 replaced
export letand$:with runes such as$propsand$derived. A team that only knows Svelte 4 will write older code. Our runes post shows the difference. - Ask what share of their work is Svelte. A firm that does Svelte once a year will reach for React habits.
- Ask who maintains it after launch. The Svelte hiring pool is smaller than React’s. Make sure the code is plain enough for the next developer.
- Check the minimum and the rate. On this list, rates run from $25 to $199 an hour on Clutch.
- Read reviews for the framework, not the stars. Every rated firm here is between 4.8 and 5.0. Search the review text for “Svelte”. Our guide to vetting an offshore team covers the rest.

Where Dawloom fits
We write Svelte 5 every week, but we have no public Svelte client project. Our named client work, such as FurnitureAxis, is built in Next.js. This site is Astro with Svelte 5 islands, and our free tools, such as the AI crawler checker, are Svelte 5 components. That is our own product, not client work.
We bill $30 an hour, or by milestone, and don’t publish a minimum. Our reviews are 4.9 from 343 on Fiverr, 5.0 from 156 on Freelancer.com, and a 4.9 average across 13 jobs on Upwork. They cover all our work, not only Svelte.
We fit interactive Svelte islands or tools inside a fast content site. Pick Mainmatter or Okupter if you need to see a shipped SvelteKit client app first.
FAQ
Is Svelte good for a business app?
Yes, for teams that know it. It compiles to small, fast code, and SvelteKit handles routing, server rendering, and forms. The trade-off is a smaller hiring pool and fewer ready-made component libraries than React.
How much does a SvelteKit developer cost?
On this list, Clutch rates run from $25 to $49 an hour (Dipa Inhouse) to $150 to $199 (Sketch Development), and Okupter publishes $6,000 per two-week sprint, checked 2026-10-14.
How can I tell if a site is built with SvelteKit?
View the page source. SvelteKit sites load scripts from a path containing /_app/immutable/ and usually include __sveltekit in the HTML. Next.js sites load from /_next/.
Why is Mainmatter first when only 8% of its work is Svelte?
Because it scores well on everything else: four named Svelte clients, a Svelte core team member on staff, and independent reviews. The share criterion is there so you know Svelte is a newer line for them.
