No signup: two free calculators and priced AWS & GCP instance pages to check idle cloud waste before you provision.
One team saved $42,983 in 5 months
Your dev servers run 24/7.
Your team uses them 8h a day.
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.

How does Idlefy work?
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.

- 1
Tag the VMs you hand over
Dev boxes, staging, GPU rigs. Untagged machines stay read-only — never started, never stopped. On AWS the IAM policy itself enforces it.
- 2
They sleep by default
A managed VM's resting state is stopped. Nobody pays for an idle Friday night again.
- 3
Lease when you need it
A tap in Slack, a message in Telegram — or one click on the web — starts the machine for the hours you choose. Extend anytime.
- 4
It shuts itself down
At expiry the VM stops on its own — still working? On Pro the Safety System grants one 30-minute grace first. Persistent disks stay.
See the burn in 5 minutes
A free idle audit shows what 24/7 servers really cost you — before you change anything.
1. Connect, read-safe
One cloud connection. Idlefy sees all instances but can control only ones YOU tag — on AWS that's verifiable in the IAM policy, not a promise.
2. Scan 30 days
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.
3. See the burn
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.
For the people who start servers — and the people who pay for them
For engineers
- Start a VM straight from Slack or Telegram — no tickets, no consoles.
- Extend or release from the same app when plans change.
- Your workflow stays yours: SSH, IDE, CI — the machine is simply on when you need it.
- You decide what Idlefy can touch. The tag is the boundary, and you set the tag.
For engineering leaders
- A bill that tracks usage, not calendar time — leased hours are the only running hours.
- The free Idle Audit prices every wasted hour before you commit to anything.
- Full audit trail: who started what, when, and for how long.
- Budgets and roles per team, so savings survive the next quarter too.
Teams typically waste $2,000–5,000/mo on idle servers. Idlefy starts at $50/mo — up to a 100× return.

Your security is Priority #1
Least-privilege access
We don't ask for admin rights. Only the narrow, tag-scoped permissions the product actually needs.
Keyless cloud federation
OIDC (Web Identity Federation) on AWS, Workload Identity Federation on GCP — keyless on both, automatic token rotation, no access keys to manage.
Sign in with your own identity provider
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.
