Zenhook
Read full descriptionHide full description
Your app, live. On your phone. A sale, a new player, a sign-up, an error, a site that goes down. Zenhook puts what happens in what you build on your phone, as it happens. 1,000 events a month, free. No SDK. INBOX - Every event of your workspace, newest first, one line each. Tap a line to read its message, fields and link. - While you were away: the top line adds up what came in, with the unread count, the money received and the errors. - Errors and warnings are marked. A deploy shows its steps and the one that failed. - Mark all as read in one tap. Long press an event to ask the Assistant about it. MONITORS - Add a URL and Zenhook checks it every minute from outside your servers (every 30 seconds on Pro). - Each site shows its response time now, its latency over the last 24 hours and 24 bars, one per hour, with its uptime over 24 hours. - When a site goes down, you get an alert, and its tile turns red and says for how long. You get another alert when it is back up. - A failure counts only when a second check confirms it, so one network blip does not wake you up. - For a service on a private network (VPN, LAN, localhost), a command you run inside the network reports each check. ASSISTANT - Ask about your events in plain words: βWhat happened this week?β, βAny errors in the last 24 hours?β, βWho signed up?β - It answers from your workspace's events. Your conversations are kept, grouped by day, with search. HOW IT WORKS 1. Create a channel: sign-ups, payments, errors, deploys. 2. Copy its webhook URL. 3. POST JSON to it from your code, your CI, a cron job or a no-code tool. 4. Your phone pings. That's it. An event can carry a title, a message, a level (info, success, warning, error), an emoji, fields, a link and the person it is about. If it can send an HTTP request, it works with Zenhook. NOTIFICATIONS - Push on your phone and, if you want it, email, set per workspace and per channel. - When the same event keeps coming, you get the first few, then at most one notification an hour with each event and its count. The Inbox still shows everything. FREE TO START Free: 1,000 events a month, 3 channels, 3 monitors and 50 questions to the Assistant. Pro raises the limits to 50,000 events a month, unlimited channels, 20 monitors and 5 members. In English, French and Portuguese.

Waiting on your own code is a waste of your attention. A deploy that takes ten minutes. An AI coding agent grinding through a task. A cron job, a webhook, a scraper, a long build. Lert buzzes your phone the second any of them finishes β so you can walk away from the screen and get on with your day. No sign-up. No API keys. No SDK. Download the app, copy your unique URL, and POST to it from anywhere. That's the entire integration: fetch("https://lert.dev/p/your-id", { method: "POST", body: JSON.stringify({ title: "Deploy finished", body: "production - 2m 14s" }) }) No headers. No auth token. No library. The URL is the authentication β which is exactly what removes the accounts, keys, and config every other tool makes you set up. BUILT FOR β’ AI coding agents β get buzzed when your agent finishes a task, breaks, or needs your input β’ Automations β cron, webhooks, and no-code automation tools β’ Dashboards & monitoring β fire an alert the moment something crosses a line β’ Deploys & CI β done, failed, or waiting on you β’ Your own apps β an order lands, a payment clears, stock runs low CONNECT YOUR AI ASSISTANT Lert ships an MCP server β add one URL and your AI coding assistant can notify your phone directly, no code required. Just tell it "notify my phone when the tests pass." FEATURES β’ Unique endpoint URL, ready the moment you open the app β’ One-tap copy, plus a paste-ready code snippet β’ Channels β a separate URL per project, each named with an emoji β’ History β your recent notifications β’ Regenerate β if a URL ever leaks, kill it instantly and get a new one β’ Plain text or JSON β send whichever you like β’ Works with anything that can make an HTTP request Notifications are optional. Lert asks for permission the first time you open it, and if you decline you can still explore the app, read the documentation, and manage your subscription β you can turn notifications on later at any time in Settings. LERT PRO β SUBSCRIPTION Lert Pro Monthly gives you unlimited channels, unlimited notifications (fair-use cap of 10,000/day), and 30-day history. β’ Title: Lert Pro Monthly β’ Length: 1 month (auto-renewing subscription) β’ Price: US$2.99 per month (or the local equivalent) Payment is charged to your Apple ID at confirmation of purchase.
