# Spot.io vs ZopNight: Rightsizing > Spot.io vs ZopNight, focused on rightsizing. Where each is strong, and where ZopNight acts on waste a dashboard only reports. Source: https://zop.dev/compare/spot-io-vs-zopnight/right-sizing Published: 2026-07-01 · Author: avinash-gaurav · Tags: zopnight, comparison, spot-io, right-sizing --- Spot.io focuses on compute cost optimization through spot/preemptible instance management and elasticity. ZopNight takes a different approach, scheduling non-production resources to stop running when nobody uses them. Narrowed to rightsizing, the difference between the two comes into focus. Both operate in the cloud-cost space, but rightsizing is where the gap between reporting waste and removing it matters most. ## Where Spot.io is strong Credit where it is due: - Excellent spot instance management. - Ocean for Kubernetes cost optimization. - Automated compute scaling. - Good for production workload optimization. If those are what you are shopping for, it is a serious option. ## Where ZopNight does rightsizing differently ZopNight is built to act on the waste, not just chart it: - Covers databases, storage, ML, and more, not just compute. - Non-production scheduling is the biggest quick win. - Works across VMs, databases, K8s, and serverless. - Simpler setup with broader resource coverage. For rightsizing specifically, ZopNight acts rather than reports: it schedules non-production on your hours, rightsizes the oversized, and cleans up the idle, all measured against real usage. Spot.io pricing is based on savings achieved. ZopNight charges per scheduled resource. See it on [AWS EC2](https://zop.dev/zopnight/aws/ec2) and the discipline behind it in [FinOps](https://zop.dev/learn/finops). ## How ZopNight schedules non-production resources The loop that does this is deliberately mechanical, and it starts read-only. You connect your cloud provider with a read-only role, and ZopNight discovers every non-production resources across your regions and accounts. It records a per-action permission verdict for each one, so you can see where it can list a resource but not yet stop it, and you review that inventory, filter it by status or type, and search for the specific resources you care about before anything is scheduled. Scheduling itself is a cron you write once in plain terms, stop at 7 PM, start at 8 AM on weekdays, pinned to your timezone so the jobs fire at local business hours rather than UTC. A weekly 24-hour grid shows the schedule visually so you catch gaps and overlaps before you save, and an estimate of active versus inactive hours appears before you commit. Resources attach individually or bundle into groups like "dev-cluster" or "staging-db" so a whole environment follows one cadence. Actions run in dependency order, so a database comes up before the app server that depends on it. When something needs to stay up, an override forces a non-production resources ON or OFF for a defined window, carries a reason so teammates understand why it exists, and expires automatically so nothing is left running by accident. If a start or stop fails, ZopNight retries up to three times and falls back to a dead-letter queue rather than silently dropping the action, and every state change lands in an audit trail that records whether a schedule, an override, or a specific user triggered it. ## Getting started Getting started is intentionally low-stakes: - Connect your cloud provider with a read-only role. Nothing is scheduled or changed at this stage. - Let ZopNight discover your non-production resources and review exactly what it found, filtered by account, region, and status. - Create a schedule in your timezone and attach the non-production resources or groups you want it to cover. - Watch the first cycle run, with Slack, Teams, or Google Chat notifications on every start, stop, and failure, then layer in idle cleanup and guided rightsizing. Production stays excluded by default throughout, and because discovery and recommendations are read-only, you can prove the value before you enable a single action. ## Frequently asked questions ### Does ZopNight replace Spot.io for rightsizing? They solve different halves. Many teams keep Spot.io for what it is good at and add ZopNight to act on the waste, scheduling, rightsizing, and idle cleanup. ### Can I run both? Yes. ZopNight connects read-only, so you can evaluate it alongside Spot.io without disrupting anything.
