The repeatable job the product performs
Availability and legality of required data

The achievable core
- A focused, single-user version of Better Stack / UptimeRobot paid'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
- global multi-region probes
- on-call scheduling & escalation policies
- incident timelines and postmortem tooling
- phone-call alerts
- Reliability at the vendor's scale is an operations problem, not a prompt.
- The last 20 percent is sync, migration fidelity, speed, and edge cases.

Build brief — a focused alternative to Better Stack / UptimeRobot paid
Context
**Better Stack / UptimeRobot paid** — A cron loop, a fetch, an alert webhook, and a status page. It currently costs $30/mo.
A cron loop, a fetch, an alert webhook, and a status page. The $30/mo is for the dashboard gloss.
This brief describes a focused, single-operator replacement for the part of Better Stack / UptimeRobot paid 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 Better Stack / UptimeRobot paid'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 an uptime monitor like UptimeRobot. Requirements:
A config file (monitors.json) listing URLs with: name, interval seconds,
timeout, expected status code, and an optional keyword the body must contain.
A single long-running Node or Python process that checks each monitor on its
interval, records results (SQLite: timestamp, status, latency ms), and tracks
state transitions.
On DOWN or RECOVERED transitions (after 2 consecutive fails to avoid flaps):
send a webhook (Discord/Slack/Telegram format, URL from .env) with the monitor
name, error, and duration of the outage.
A public /status page: green/red per monitor, uptime % over 24h/7d/30d, and a
latency sparkline drawn as inline SVG. Auto-refresh every 30s.
Keep 90 days of history, prune older rows daily.
One process, no queue, no Docker required; systemd unit file included.
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:
Global multi-region probes.
On-call scheduling & escalation policies.
Incident timelines and postmortem tooling.
Phone-call alerts.
Reliability at the vendor's scale is an operations problem, not a prompt.
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
**Operational risk.** The code is achievable; dependable data, integrations, and ongoing operations are the real cost.
Editorial confidence in this assessment: high. No independent one-shot implementation is linked yet.
