Square Online Review: The Square Website Builder, Documented

Ask for the Square website builder and what you get is Square Online — the ecommerce arm of Block, Inc., assembled on the bones of the $365 million Weebly acquisition of April 2018. This Square Online review documents the one product on our register that behaves like an actual business tool: a genuinely free online store with a real checkout. No other big-tech side product we cover can generate that sentence, which is why this one sits at the top of the ladder.

It is also the entry with the most fine print, because free here is collected per sale — and the per-sale price went up in January 2026. The full documentation follows.

What Square Online is

Square Online is the website side of the Square commerce stack: the same account that runs a seller's card reader and point of sale also publishes their store, with one catalog and one inventory behind both. The builder descends directly from Weebly, which Square bought for $365 million in April 2018 and gradually digested. What survives of that acquisition is a competent drag-and-drop editor grafted onto a serious commerce engine — a real editor with a decade of lineage, not a page tool improvised by a payments company. The result reviews less like a side project than anything else on our register, which the score reflects.

October 2025: eighteen subscriptions become three

On October 6, 2025, Square consolidated eighteen à la carte subscriptions — including the standalone Square Online Plus and Premium plans — into three unified plans: Square Free at $0, Square Plus at $49 per month per location, and Square Premium at $149 per month per location. There is no longer a website-only paid plan. You subscribe to Square the platform, and the website rides along with the rest of it. The unification also retired an FAQ that had grown baroque — which subscription covered which feature at which counter. Three plans, one price page.

Legacy Square Online subscribers migrate through a self-serve process whose help-page description is briskly candid about what happens to the old plan:

“…automatically cancels your Square Online hosting plan and issues a pro-rated refund.” — Square Support, plan-migration documentation, retrieved August 2026

One consequence deserves its own paragraph. The legacy Square Online Plus was $29 per month billed annually, flat, regardless of how many locations a seller ran. The plan that replaced it bills per location — and multi-location sellers on Square's own community boards have done that arithmetic loudly and unhappily. At the time of checking, Plus and Premium appear to bill monthly with no advertised annual discount, but Square's public pages are quiet on billing-cycle details, so treat that as unconfirmed rather than documented.

What $0 actually buys

The free tier is not a demo. It includes a full store: unlimited products, real checkout, order pickup, local delivery and shipping options, selling across search and social surfaces, and SEO tools — at zero monthly cost. That list would be a mid-tier paid plan almost anywhere else. Square's pitch is that it monetizes the payments rather than the software, with the free store as the funnel — and unusually for this genre, the documentation supports the pitch.

The catch is presentation. Your store lives at yourname.square.site and carries Square's branding, and moving to a custom domain requires a paid plan; domains themselves run from around $19.95 per year after the first year. Whether paid plans still bundle a free first year of domain registration was unclear at the time of checking, so we do not promise it. We audit the free tier line by line in is Square Online actually free — the short answer is yes, with an asterisk shaped like a processing rate.

January 2026: the quiet rate hike

On January 13, 2026, Square raised its online processing rates. The free plan's online and invoice rate moved from 2.9% + 30¢ to 3.3% + 30¢; the paid plans' discounted online rate moved from 2.6% + 30¢ to 2.9% + 30¢. In-person rates did not change: 2.6% + 15¢ on Free, 2.5% + 15¢ on Plus, 2.4% + 15¢ on Premium. Keyed and card-on-file transactions run 3.5% + 15¢ across the board, and ACH costs 1% — with a $1 minimum on Free and a $10 cap on the paid plans.

The structural read is simple: the free store's rent is collected at checkout, and in January the rent went up. The 0.4-point spread between Free and the paid plans is the actual price tag on the word free, printed in a font small enough that most sellers will read it for the first time on a settlement report.

The math: when Plus beats Free

That spread makes the upgrade decision computable, so we compute it. Plus costs $49 per month and saves 0.4 points on every online sale; the fixed 30¢ per transaction is identical on both plans, so it cancels out of the comparison. Forty-nine dollars divided by 0.004 is $12,250: clear about $12,250 in monthly online sales, and the rate discount alone covers the subscription. A store doing $5,000 a month online saves $20 in fees and pays $49 for the privilege; a store doing $25,000 saves $100 and comes out $51 ahead before counting features.

In-person sellers get a further 0.1-point discount on Plus, which lowers the true break-even for mixed businesses somewhat. Below those volumes, you are buying Plus for its features — QR ordering, subscriptions, the better online rate as a side effect — which is a perfectly legitimate purchase, as long as you know that is the purchase being made.

Ecommerce depth, documented

This is where Square Online stops resembling everything else we review. Inventory syncs with Square POS, so the shelf and the website agree without ceremony. Plus adds QR-code ordering and subscriptions. Premium adds real-time shipping rates, advanced reporting and 24/7 phone support, and sellers processing above $250,000 a year can negotiate custom pricing. No other big-tech side product on our register has a feature list in this genre at all — the nearest neighbor sells nothing whatsoever. The current plan lineup and free signup live at Square Online.

The Weebly ghost

Weebly — the platform underneath all of this — is not shut down. Sunset language that alarmed users in 2025 was removed, and existing Weebly sites remain live. But the platform is unmistakably frozen: new users are steered to Square Online, and the Weebly mobile apps were pulled from the app stores on December 1, 2025, leaving desktop-only management. As acquisitions go, this is the dignified version — the product was absorbed rather than executed, and its editor lives on inside the new brand. The community threads asking whether Weebly is closing have accumulated for years now, and the honest answer has not changed: not closing, not growing. If you still run a legacy Weebly site, the direction of travel is documented, and it points one way.

Verdict: the best of the side doors

Square Online closes at 8.1, scored as an actual website builder — the top of our ladder. The free tier is real, the commerce is real, and the costs are at least printed where a careful seller can read them: 3.3% + 30¢ per online sale on Free, $49 per month per location to improve the rate. Honesty about pricing is a low bar, and it is remarkable how few products in this category clear it. It is also, not coincidentally, the only product here whose parent visibly wants it to succeed.

See how it ranks against the other four side doors on our big-tech website builders register. If your ambitions have outgrown a subdomain with somebody else's logo in the footer, when you've outgrown them maps the exits, and the hidden limits of free big-tech builders catalogs the fine print across the whole field — Square's is the most honest of the set, which is the nicest thing this site says about anyone.
