AI-driven website builder with integrated business tools.
Solo tradespeople and small service businesses that need a website, a simple CRM and invoicing without assembling three tools.
Durable builds a website for a small business from a short description, then keeps going into the parts most website builders leave out. The same subscription carries a CRM, automatic lead replies, a booking calendar and invoicing. The pitch is that a one-person service business should not need three products to get online and get paid.

The target customer is obvious from the templates. Handymen, cleaners, landscapers, photographers, car detailers and coaches, rather than startups or online stores.

Sites come out looking like this: a clear service description, a booking prompt and contact details, structured the way a local customer expects. Nothing here will win a design award, and that is the correct trade for a tradesperson who needs a working site this afternoon.

Free gets a real website on a durable.site subdomain, logo and ad generation, five images a month, ten AI chat messages and a CRM holding up to ten customers. That is enough to run a very small business rather than a demo designed to frustrate you into upgrading.
The limits that will push you to pay are the subdomain and the ten-customer CRM. Both are the right constraints to charge for, since a business that has outgrown either is a business making money.
Launch at $22 a month billed yearly, or $25 monthly, adds a custom domain that Durable says is worth up to $20, advanced SEO with weekly visibility ranking, automatic lead capture and replies for up to 20 leads, and 50 images a month.
Grow at $41 yearly or $49 monthly lifts the lead replies to unlimited, adds unlimited team members and 500 images, and includes a one to one onboarding call. That call is worth more than it sounds for the audience this targets, since the people buying it are often setting up their first website.

The lead cap on Launch is the number to watch. Twenty captured leads a month sounds generous until a single advertising campaign lands, and the jump to Grow is where the pricing stops being cheap.
There is no API, so this does not connect to anything you already run. That is consistent with the audience but rules Durable out if you have existing systems.
Bundling also cuts both ways. Replacing a website builder, a CRM and an invoicing tool with one subscription is genuinely cheaper, and it means everything lives with one vendor. Moving away later takes your website, customer records and invoice history with it, so the low monthly price buys convenience at the cost of switching freely.
