RenewHelper

RenewHelper sends its reminders through Telegram, ntfy, Gotify, Bark, Resend email, webhooks or several Chinese chat and push services. A Cron Trigger checks every item twice an hour, and all data sits in one KV namespace in your account.

RenewHelper calculates each item's next due date by day, month or year, and can follow lunar calendar cycles between 1900 and 2100. Every item uses one of three modes: cycle subscription, expiration reset or fixed repeat. When an item comes due, the app can roll its due date forward by one cycle, or mark it disabled after it has been overdue for a set number of days. Reminder channels are set per item, and batch actions assign them to many items at once. Each item also sets how many days ahead to notify and at which times of day. A spending dashboard charts the past 12 months and the last three years, converts currencies at current exchange rates, and separates each bill amount from the actual cost recorded in renewal history. Upcoming renewals appear in a calendar view and in an .ics feed for iOS Calendar, Google Calendar or Outlook. The Vue 3 and Element Plus interface has dark and light themes and switches between English and Chinese. The whole app is a single Worker script, _worker.js. Login uses JWT sessions, and the Worker rate-limits login attempts in memory and in KV. Besides the Deploy to Cloudflare button, the README covers pasting _worker.js into the dashboard editor, a GitHub Actions workflow that redeploys after each Sync fork, and a Docker image that runs the same code under Miniflare.

Built for: Solo founders, freelancers and small teams who pay for many domains, servers and SaaS subscriptions and want a reminder before each renewal.
