The CoIsland film. Requests from its users appear one by one, each marked as added: Cursor, Mistral Vibe, a choice of screen, a folder and agents for each monitor. GitHub Actions and Sentry fill up, and the island at the edge of the screen keeps only what needs you. A failed deploy goes from the Inbox to an agent, one of Claude Code, Codex, Cortex Code, Mistral Vibe and Cursor; it finds the undefined price, gets the build passing, and asks before it acts. One key moves through the Inbox, from CI to errors to questions, until each is resolved. Your keys stay on your Mac, with no CoIsland server and no account. CoIsland: work with AI, stay in control.
Your whole engineering stack. One island.
Builds, deploys, pipelines, pull requests, incidents: only what needs you, on one small island at the edge of your screen.
No server and no account: CoIsland talks to your tools straight from your Mac.

Work. Side projects. School. Three islands. So I brought them all to one island.
I'm an Applied AI Engineer in Montréal. I'm also a software engineering student, and I build side projects most nights. That's three workspaces, each with its own Jira, GitHub, deployments and inbox. Nothing was hard on its own. Keeping track of all of it was.
So I built the one place I was missing: a single view of every workspace, where I already look, at the top of my screen. Every alert, issue and deployment says where it comes from: my job, my project or my coursework. One glance tells me what broke and where, and I act on it right there, or hand it to an AI agent while I keep the final say. For the experience, and even this website, I took a lot of inspiration from Codenotch and One.
I've run my days from the island for more than two months. Nothing slips between workspaces anymore, and I no longer pay the tab-switching tax. If it does the same for you, or doesn't, write to me. I read every message.
On my own island every day since July 2026
Free for good. Or pay once.
CoIsland Community monitors all your agents, plus 2 monitors on your dev tools, with no card and no account. Lifetime runs every monitor, paid once.

Questions
Which tools does CoIsland connect to?
35+ today, each through its own connector: your data (Snowflake, Databricks, dbt), your code and deploys (GitHub, Vercel), your issues (Jira, Linear, Notion), your on-call (Sentry, PagerDuty, Datadog), and your mail and calendar. The full list is on the Connectors page; more are on the way.
Can I ask for a connector?
Yes: write to hello@coisland.app with the tool you use and what you would watch in it.
Can an AI agent act on an alert?
Hand an alert to Claude Code, Codex or Cortex Code: the agent opens in a terminal under the alert, with the whole alert as its first message. Claude Code and Codex run in their auto mode, doing what is safe and asking you for the rest; Cortex Code asks before it acts. No agent closes an alert: you do.
Does my data go through a CoIsland server?
No. There is no CoIsland server: the app talks to your tools directly from your Mac. When you hand an alert to an agent, that agent's own service receives it.
Where are my credentials stored?
Every connector's token is kept in the macOS Keychain. Snowflake connections can be imported from ~/.snowflake, the files the Snowflake CLI and Cortex Code use, which CoIsland never writes.
How often does a monitor check?
Each monitor runs on its own schedule, such as every 30 seconds or every 5 minutes.
What do I need?
A Mac with Apple Silicon (M1 or later) running macOS 14 or later. It does not run on Intel Macs.
What is free?
CoIsland Community monitors all your agents, whoever started them, and runs 2 monitors on your dev tools, for good, with no card and no account; with more monitors, the 2 you created first run. The island, dashboards and the Inbox work without a licence too. Lifetime runs every monitor.
How much does it cost?
CoIsland Community is free for good and monitors all your agents, plus 2 monitors on your dev tools; Lifetime runs every monitor, paid once, from $29, with every update for good, for up to 2 Macs and no subscription. Within 30 days, you can get a full refund, for any reason.
Work with AI. Stay in control.
