Lifetime Deal
Our take: Worth a look for agencies and SaaS teams that collect video testimonials and want to avoid a monthly subscription. Skip it if you need lots of video storage on a low budget, or if you want a proven, long-established platform. The cheapest tier shows a powered-by badge and has tight caps.

testimonials.ltd is a tool for collecting customer testimonials, in text, photo and video form, and putting them to use. According to the listing, you set up “brand spaces” and collect reviews through a no-login link. You can also use embeddable widgets inside your app or emails on the higher tiers.

It is sold as a lifetime deal on AppSumo in five tiers, from $69 to $999. The listing does not include a product video, so what follows comes from the listing text alone. We have not tried the tool ourselves.
Here is what the listing says the product does:
The basic flow, as the listing describes it, is simple. You create a brand space and send customers a collection link. They submit a text or video testimonial without needing to log in.
On higher tiers you can instead embed a widget in your product or an email. If someone starts a review and drops off, the partial answer is saved so you can follow up.
Video is the one metered resource. If you go over your slot cap, extra videos are locked rather than deleted. You can then free up space, upgrade, or buy more slots at $5 a month per 50.
The listing mentions “walls” and “share pages” for displaying testimonials, but gives no detail on layouts, embed options or design controls. Check the live product for these before buying.

There are five lifetime tiers: $69, $149, $299, $599 and $999. All include lifetime access, all future plan updates, and the ability to switch between tiers. You must activate your license within 60 days, and refunds are available through AppSumo within 60 days for any reason.
The feature table lists five columns. From the listing’s FAQ, they appear to run from Max down to Solo, with Pro, Agency and Studio in between. The listing does not state which price matches which column, so confirm this on the AppSumo page before you pick. The differences between columns are large:
The lowest column gives you one space, five video slots, no widgets and a visible badge. That is enough to try the product, but a business that relies on video will hit the cap fast.
Existing testimonials.ltd users can add the AppSumo plan to their account, and later upgrades or downgrades on AppSumo move the account to the matching tier automatically.
A good fit:
Think twice:

The 60-day refund window lowers the risk. A sensible approach is to buy the tier that matches your real video volume, test the collection flow with a few real customers, and decide before the window closes. Remember that you can switch tiers later, but the video cap is the limit most likely to affect you.
According to the listing, yes. You pay once on AppSumo and keep your tier's features and limits with no renewal. The only optional recurring cost is extra video slots at $5 a month per 50.
Text testimonials are unlimited on every plan. Video is the metered resource, with a set number of slots shared across your spaces. Videos over your cap are locked but not deleted.
The listing says you can get a refund through AppSumo within 60 days of purchase, for any reason. You must also activate your license within 60 days.
