The achievable core
- A focused, single-user version of Senja / Testimonial.to's main workflow.
- Build a focused single-user workflow with real persistence, search, and export.
- A responsive interface with real empty, loading, success, and error states.
The parts a prompt cannot buy
- video testimonial recording in-browser
- imported reviews from other platforms
- their widget templates gallery
- a hosted collection URL that isn't yours
- The last 20 percent is sync, migration fidelity, speed, and edge cases.

The brief
Context, requirements, acceptance criteria, non-goals, and the full production standard — as Markdown, ready for any coding agent.
Build brief — a focused alternative to Senja / Testimonial.to
Context
**Senja / Testimonial.to** — A form, an embed widget, and a wall page. It currently costs $25/mo.
A form, an embed widget, and a wall page. $300/yr for what is essentially a guestbook.
This brief describes a focused, single-operator replacement for the part of Senja / Testimonial.to that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.
What you are building
A focused, single-user version of Senja / Testimonial.to's main workflow.
Build a focused single-user workflow with real persistence, search, and export.
A responsive interface with real empty, loading, success, and error states.
Requirements
Non-functional
Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
Security: server-side secrets, validated input, and no credentials in the client bundle.
Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
Portability: the operator can export their data and leave without losing it.
Implementation brief
Build me a testimonial collection and display tool like Senja. Requirements:
A public /submit page: name, role/company, avatar upload (or auto-fetch from a
provided URL), star rating, and the testimonial text. Store submissions in SQLite
with an approved flag defaulting to false.
An /admin page (basic-auth from .env) listing submissions with approve/delete
buttons · nothing shows publicly until approved.
A public /wall page: masonry grid of approved testimonials, clean cards with
avatar, name, stars, and text. Mobile-friendly, dark mode support.
An embeddable widget: /embed.js renders the wall into any page via one script
tag + a div, iframe-free, styled to inherit the host page's font.
Image uploads resized server-side to 128px avatars, stored on disk.
Node or Python, single small server, deploy instructions for a VPS.
Delivery standard
Inspect the repository first, then write a short implementation plan before writing code.
Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
Add structured logs around every external call and return actionable errors without leaking sensitive details.
Write unit tests for the core logic and one automated test of the main user journey.
Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.
Acceptance criteria
A clean install starts the app using only the README and .env.example.
The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
Tests, type checking, linting, and a production build all pass with no ignored failures.
No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.
Non-goals
Do not build these, and do not claim to have replaced them:
Video testimonial recording in-browser.
Imported reviews from other platforms.
Their widget templates gallery.
A hosted collection URL that isn't yours.
The last 20 percent is sync, migration fidelity, speed, and edge cases.
What you still own after launch
Run migrations, backups, restores, and dependency updates.
Test the critical journey after every model, API, or hosting change.
Monitor failures and fix the edge cases a first prompt will miss.
Risk
**Manageable.** A personal version is realistic if you test the critical journey and keep reliable backups.
Editorial confidence in this assessment: high. No independent one-shot implementation is linked yet.
