Monitor Stripe payments from your Mac's notch

What CoIsland watches in Stripe

Each monitor kind brings its own query and its own card in the notch.

• Failed payments

  A charge is declined or fails, with the decline reason the bank gave.

• New disputes

  A customer disputes a payment, with the date to respond by.

• Subscriptions

  A subscription starts, or is canceled now or at the end of its period.

• Failed payouts

  A payout to your bank fails, with Stripe's reason.

• Low balance

  The available balance of a currency drops below the amount you set.

Connect it in three steps

1. 1

   In the Stripe Dashboard, create a restricted key under Developers › API keys with Read on the resources you watch and None on the rest.

2. 2

   Add a Stripe connector with the key. Test connector shows live or test mode and what the key can read.

3. 3

   Pick a monitor kind or an example, choose how far back it looks, and choose when it alerts.

Built for Stripe

Then hand it to an agent

A click on the alert opens the agent in a terminal under it, with the whole alert as its first message.

• Claude Code

  Anthropic's coding agent, in its own CLI.

• Codex

  OpenAI's coding agent, in its own CLI.

• Cortex Code

  Snowflake's coding agent, in its own CLI.

Other connectors

• Gmail

  Hear about the emails that matter, not every email. Unread mail, chosen senders, labels, Drive comments and invitations reach your Mac's notch, and nothing is marked read.

• Calendar

  The calendars Calendar.app already shows (iCloud, Google, Exchange, subscriptions), or a calendar's secret ICS feed, in your Mac's notch. A countdown to your next meeting, a warning before it starts with one click to join, and news of invitations and changes.

• Dock badges

  One watch over every app that badges its Dock icon. Slack, Microsoft Teams, Outlook, Mail, Messages, Discord, WhatsApp or any other app tells the notch when its count goes up, with no account or token for any of them.

• Apple Mail

  Every account Mail already has, iCloud, Exchange, Gmail or any IMAP, in your Mac's notch. New unread mail in your inboxes, or only from the people and domains you pick, with no password given to CoIsland.

• GitHub

  Monitor GitHub for what needs you, not everything that moves. Reviews, failed Actions runs, releases and security alerts, on github.com or GitHub Enterprise.

• Vercel

  Watch Vercel deployments, stuck builds and project domains. A failed build reaches your Mac's notch with its error, and the alert shows the failing step and the end of the build log.

• GitLab

  Watch GitLab on gitlab.com or a self-managed instance. A review request, a failed pipeline or a new to-do reaches your Mac's notch, and the alert shows the merge request with its description and comments, or the jobs that failed.

• Cloudflare

  Watch Cloudflare Pages deployments, Worker errors and your zones. A failed build reaches your Mac's notch with its failing step, and the alert shows the end of the build log.

• Render

  Watch the deploys of your Render services and whether they are suspended. A failed deploy reaches your Mac's notch with its commit, and a suspended service says who suspended it.

• Jira

  Monitor Jira with the JQL you already write. New matches, status changes, comments, SLAs near a breach and sprint scope reach your Mac's notch, from Jira Cloud or Data Center.

• Linear

  Monitor Linear with its own issue filters. New matches, status changes, issues in triage, SLAs at risk, your mentions and projects going off track reach your Mac's notch.

• Confluence

  Monitor Confluence Cloud without the email digest. Mentions, page edits, new comments, your tasks and any CQL reach your Mac's notch, signed in with the same API token as Jira.

• Asana

  Know what landed on your plate and what is late. Tasks assigned to you, due dates, new tasks in a project and comments on your tasks reach your Mac's notch, read with your own Asana token.

• ClickUp

  Know what is yours and what is late. Tasks assigned to you, their status and due dates, and new tasks in a list reach your Mac's notch, read with your own ClickUp token.

• Todoist

  Know what is due before it is late. Tasks due today or overdue, new tasks in a project, or any filter you already use reach your Mac's notch, read with your own Todoist token.

• Notion

  Know when a Notion row lands on you, a page you care about changes, or someone comments. Read with your own personal access token, straight from your Mac.

• Shortcut

  Know when a story lands on you, moves to review, or an iteration is about to end with work still open. Read with your own Shortcut API token.

• Airtable

  Know when a record starts matching a formula, or someone edits one, without keeping the base open. Read with a personal access token scoped to the bases you pick.

• Reminders

  The reminders Reminders.app already has, iCloud or Exchange, in your Mac's notch. A warning before one is due, another when it is overdue, and news when someone adds to a list you share.

  Monitor Sentry with the searches you already write. New errors, regressions, issues assigned to you, failing crons, sites down and new releases reach your Mac's notch, from sentry.io or your own Sentry.

• PagerDuty

  Know at a glance whether you have to move. Incidents assigned to you, your teams' incidents and your on-call shifts reach your Mac's notch, read with your own PagerDuty token.

• Datadog

  Know when a Datadog monitor fires without living in the dashboard. Monitors in alert, incidents and metric thresholds reach your Mac's notch, read with your own application key.

• New Relic

  Run the NRQL you already trust, and see New Relic's alert issues the moment they open, in your Mac's notch, with your own User key.

• Langfuse

  Your LLM app fails, overspends or gets a thumbs down, and the notch says so. Langfuse's errors, cost, latency and scores reach your Mac, read with a project's key pair on Langfuse Cloud or your own Langfuse.

• Snowflake

  Monitor Snowflake with read-only SQL. A failed task, a row that breaks a rule or a sudden spike reaches your Mac's notch, and Cortex Code, Claude Code or Codex can take it from there.

• Databricks

  Monitor Databricks from your Mac's notch. A failed job run, a failed pipeline update or a triggered SQL alert reaches you for free, and read-only SQL on a warehouse watches the data itself.

  Monitor dbt from your Mac's notch. A job run that fails, a run that takes too long or a source that goes stale reaches you, with the failing step's log one click away.

• PostHog

  Monitor PostHog from your Mac's notch. A HogQL query that finds something, an insight crossing a number or an exception seen for the first time reaches you without opening a dashboard.

• Supabase

  Monitor Supabase from your Mac's notch. A paused or unhealthy project, a new security lint or a row your SQL finds reaches you, with nothing but a personal access token.

• PostgreSQL

  Monitor PostgreSQL from your Mac's notch. A read-only query checks your database on a schedule, and each new row it finds reaches you once.

  Monitor MySQL and MariaDB from your Mac's notch. A read-only query checks your database on a schedule, and each new row it finds reaches you once.

• ClickHouse

  Monitor ClickHouse from your Mac's notch. A read-only query, or a health check on the system tables, runs on a schedule, and each new problem reaches you once.

• HTTP / JSON

  Point CoIsland at any address. A JSON value that changes or crosses a threshold, a new element of a JSON list, or a page that goes down or starts saying "In stock" reaches your Mac's notch.

• RSS / Atom

  Watch any feed. A new GitHub release, a new post on a blog, or a Hacker News story that says your keyword reaches your Mac's notch, with the article one click away.

• Status pages

  Know when a service you depend on is down before your users tell you. Incidents, their updates, components going down and the page's overall status reach your Mac's notch.

• Shell command

  Run a command or a script on your Mac on a schedule. A new line it prints, a new object in its JSON, or a failure reaches the notch once.
