Agent Notifier

Agent Notifier is a push notification service built for people who run AI coding agents. You kick off Claude Code, Codex CLI, Copilot CLI, Gemini CLI or Cursor on a long task, the terminal goes quiet, and you have no idea whether the run shipped, stalled, or is sitting on a question it needs answered. Agent Notifier turns that silence into a live feed on your phone, so every milestone, blocker and approval request lands as a notification instead of getting lost in a tab you stopped watching.

The behaviour it's trying to kill is tab babysitting. Anyone who has handed a twenty minute job to an agent knows the routine, alt-tabbing back every couple of minutes just in case it needs a yes or a no. That check-in loop is cheap on its own and expensive in aggregate, because it keeps you tied to the screen for work you already delegated. The site frames the product as paying for calm rather than for another dashboard, which is a fair description of what it actually sells.

Setup is deliberately small. There's a one-line keyless installer, curl -fsSL https://notifier.aicrew.in/i | sh, which drops a notify.py file into ~/bin and links the machine through a browser approval step. No secret ever touches your clipboard or your shell history, which matters if you've ever pasted a token into a terminal that logs everything. The client is pure Python 3 standard library, so there's no SDK, no daemon and no dependency tree to maintain, and it runs on macOS and mainstream Linux. From there you drop one block into CLAUDE.md or AGENTS.md and the agent reports for itself, or you call the HTTP API directly by posting to /api/v1/messages.

Notifications aren't just text. The service carries progress bars, images, audio, video, PDFs, arbitrary files, deep links and action buttons, so whatever the agent produces can land on the phone rather than staying stuck on the machine. Action buttons show up on the lock screen, which means you can approve, deny or open a run without unlocking, and the answer is recorded against that run so nothing quietly stalls waiting on you. Setting the as_audio flag delivers the update as speech instead, useful when you're driving or walking and would rather hear the summary than read it. Each repo can also get its own channel with a colour, an icon and a separate API key, so work accounts, side projects and CI runners don't step on each other.

The API surface is small enough to read in a sitting. A notification is a single POST to /api/v1/messages carrying a priority, a colour, any attachments and whichever action buttons you want on the lock screen, and the sample call includes a client event id so a retried send can be de-duplicated rather than arriving twice. Per-project keys sit underneath all of that, which is what lets a work account, a side project and a CI runner send through the same phone without their alerts blurring into one stream. The listed callers are GitHub Copilot CLI, Claude Code, Codex CLI, Gemini CLI and Cursor, though in practice anything that can run a shell command or make an HTTP request can send a message.

An optional session watcher goes further than one-off pings. It adds hooks for live agent sessions, approvals, tool-call history and per-session inboxes, which turns the phone into a thin view of what the agent is doing rather than a bell that rings once at the end. That's the part that separates it from generic push, and the site makes the comparison directly, arguing that Pushover, ntfy.sh and Slack webhooks treat an AI agent like a smart-home sensor while this is wired for hook events, threaded sessions and tap-back replies the agent picks up on its next loop. It positions itself as a drop-in upgrade for anyone already on those services and keeps a similar API shape so migrating is short work.

It fits solo developers and small teams who run agents unattended, plus anyone who starts long migrations, builds or CI runs and would rather be told when they finish than sit and watch. The iPhone app is the main client today, with an Android beta open to join and a web feed alongside it. Pricing is freemium and honest about its shape. The free tier opens with three days of unlimited sending, counted from your first notification rather than your signup date, then settles into a daily allowance that never expires, and the API tells you exactly when that allowance resets instead of failing silently. Pro lifts the cap at $9.99 a month or $99.99 a year, billed through Apple and cancellable from iOS subscription settings. Every feature is unlocked on the free tier, including unlimited projects, per-project API keys, all media types and action buttons, so paying buys volume rather than functionality, and teams that need a custom cap can email the team to arrange one.
