Idlefy flips the default: servers stay off. Your team starts one for exactly as long as they need — from Slack, Telegram, or Web — and it shuts itself down when the timer runs out. No algorithm guessing. Up to 67% off your cloud bill.

Not an idle detector. A different default.
Idlefy is a cloud cost platform built on one rule: development servers stay stopped unless someone actually needs them. Instead of hunting for idle machines after the money is spent, it flips the default — a VM is off until an engineer takes a lease on it. You pick a machine in Slack, Telegram, or the web dashboard, choose how long you need it, and it starts in about a minute. When the lease expires, the server shuts itself down.
Need more time? Extend from the same chat. Idlefy warns you before the timer runs out — and if you're still mid-task at expiry, on Pro the Safety System grants one 30-minute grace period before the force-stop. The timer is always set by a person — Idlefy never decides on its own that a server looks idle. Persistent disks survive every stop, and Idlefy only controls servers you explicitly tag — on AWS that boundary is enforced by the IAM policy itself.
Dev boxes, staging, GPU rigs. Untagged machines stay read-only — never started, never stopped. On AWS the IAM policy itself enforces it.
A managed VM's resting state is stopped. Nobody pays for an idle Friday night again.
A tap in Slack, a message in Telegram — or one click on the web — starts the machine for the hours you choose. Extend anytime.
At expiry the VM stops on its own — still working? On Pro the Safety System grants one 30-minute grace first. Persistent disks stay.
Idlefy creates it in your own AWS account. Lease it and it starts; when the lease ends, it stops itself.
No machine yet? Idlefy builds one for you. Pick a size, an operating system and your SSH keys. Idlefy sets up the subnet and the security group, creates the machine stopped, and puts it on the same lease timer as every other server it manages.
Ready-made sizes for solo work, team work and GPU, or any machine type your organization allows. Ubuntu, Debian or Amazon Linux — with the NVIDIA driver already installed for GPU boxes. A short project? Set a lifetime and the box deletes itself when it is done.
Where and how big, the details, who can reach it, review. By default SSH is open only from your own IP address.
The machine lives in your AWS account and AWS bills you directly. While it is stopped, you pay only for its disk.
Change the type of a stopped box in seconds and see the hourly difference first. The disk stays as it is.
Idlefy never logs in to the machine. Only your public SSH keys go onto it, and Idlefy manages only the resources it created.
AWS only for now. On Pro, create and lease a dev box from Claude Code or Cursor through the Idlefy MCP server.
A free idle audit shows what 24/7 servers really cost you — before you change anything.
One cloud connection. Idlefy sees all instances but can control only the ones you tag — on AWS that's verifiable in the IAM policy, not a promise.
A month of usage history, analyzed read-only from data your cloud already stores. Nothing to install — and the audit never touches a running machine.
Every idle hour, priced. Per instance, per hour of the week. Then put the worst offenders on the lease schedule.
The audit finds the waste. Shutdown stays on the lease timer your team sets — never on a guess.

We don't ask for admin rights. Only the narrow, tag-scoped permissions the product actually needs.
OIDC (Web Identity Federation) on AWS, Workload Identity Federation on GCP — keyless on both, automatic token rotation, no access keys to manage.
On Pro, connect Okta, Auth0, or another compatible OIDC provider and keep joiners and leavers where they already live. Domains are proven by DNS before they grant anything, and SSO can be made mandatory. How it works.
