If you build client websites for a living, the comparison that matters between Duda and Seedly Sites is not just price, it is what you get and what you keep. Straight about both, including where Duda wins.

The honest version
Duda's Agency plan is $52 a month for four sites, then $17 per additional site. A 50-site roster is $52 plus 46 more at $17, about $834 a month, so roughly $10,000 a year, recurring.
Seedly Sites is a one-time $1,199 license plus flat hosting, free to start and about $200 a month for unlimited sites, with no quota.

You own it
Competitor pricing and feature availability verified September 2026; plans vary and change often, so confirm current details on each vendor's site. Seedly Sites is a one-time license plus your own flat hosting.
The math that matters
Duda is genuinely built with agencies in mind, but it charges quotas and per-site fees, with no platform ownership and only a stripped-down site export.
Seedly Sites has no site quota, flat hosting, and the full source you own and host yourself.
The whole point
Duda is genuinely built for agencies, but it still charges quotas and per-site fees, and you never own the platform; the site export it does offer strips the dynamic features. As your roster grows past its tiers, you are renting harder every month for something you cannot keep.
Own it instead: one license for unlimited tenants with no quotas, a real multi-tenant CMS, portable static output your clients own, and the source code itself. Same agency focus, none of the metered rent.
Don't take our word for it. Take theirs.
Every review 5 out of 5 on Trustpilot. These are Seedly owners on the code they were handed and whether I stood behind it. I build Seedly Sites the same way.
Read every review →Getting out
Because you own and host the platform, you bring client sites over from Duda in batches and run Seedly Sites alongside it while you rebuild, then point each domain across when it is ready. There is no per-site clock and no monthly bill ticking while you migrate.
The porting tools reproduce an existing site to near 1:1 inside the builder, and any URL that changes gets a 301 through the managed redirect workflow, so the client keeps the rankings you were paid to protect. You switch on your timeline, not a vendor's.

The verdict
Duda is one of the few platforms actually built for agencies, and I respect that. But it still charges quotas and per-site fees, and you never own the platform or the output. As the roster grows, owning it just wins.
Choose Seedly Sites if
your client count is growing and you want unlimited sites on one license you own.
Choose Duda if
you want a hosted agency platform with built-in client billing and don't need to own it.
