Ask your happy customers for a testimonial, and show the ones you approve
Send one link. Customers write a few lines and tick a box agreeing that you may publish them. You approve or hide each one, and a single script tag shows the approved ones on your site. It runs on your own server with the data in one file, so there are no tiers, no seat fees and no testimonial caps. Read the source or deploy it below.
The wall your visitors would see sample data
These three are invented to show the layout. Nobody said them. Your wall only ever contains what your customers submitted and you approved.
Why use this instead of what you do today
| Today | Catch | Testimonial Keeper |
|---|---|---|
| Testimonial.to, Senja, Shoutout and similar | Paid tiers cap testimonials, forms or the widget; the data lives with them | Unlimited, one JSON file you own, no fee |
| A Google Form and copy-paste | No approval flow, no consent record, no widget | Consent stored per entry, approve/hide, embeddable wall, CSV export |
| Screenshots of emails | No permission on record, awkward to update | Customer-written words shown only after you approve |
Honest limits: text only (no video), one admin key, no import from review sites, and it cannot prove a submitter is a real customer.

Questions
Do customers have to agree before I publish?
Yes. The form has a required consent tick and the agreement is stored with each testimonial. Nothing is public until you approve it, and the text is never edited.
Where does the data live?
In one JSON file on the server you deploy in your own account. The author runs nothing in between and never sees your customers.
Can a testimonial hijack my page?
No. The embed renders inside a shadow root using textContent only, so a testimonial can never inject markup or restyle your page.
Does it support video?
Not yet. It is text and an optional 1-5 rating, which keeps it small enough to read in an evening.
Is it a review site?
No. It collects words from your own customers for your own site. Do not mark them up as independent third-party review ratings.
