Compute must run in the home region; capacity may be unavailable and idle instances may be reclaimed. Payment card required for account verification. Boot volumes use the shared 200 GB allowance; paid account overages can incur charges. Verify tenancy-specific A1 limits.

Free e2-micro usage only in us-west1, us-central1 or us-east1. The VM allowance is pooled by running hours across those regions, not one free VM in every region. GPUs/TPUs, other disk types, excess egress, IP addresses and other billable resources are not covered. An active Cloud Billing account is required.

IPv6-only (no included IPv4); connection throttled to 1 Mbit/s after 1 TB/month. One-month contract requires manual renewal; account verification and capacity/order availability apply. Paid IPv4, extras and licensed operating systems may cost money. Card and commercial-use terms not explicitly confirmed.

CloudStack software is open source, not a provider-hosted free VPS or pre-funded compute credit. You must provide and operate your own hypervisors/physical compute hosts, networking, storage and associated cloud infrastructure; commercial support is optional and separate.

You must supply and pay for your own GCP/AWS instances, storage, networking, DNS, or bare-metal hosts; this is NOT free hosted compute. Above 16 total worker-host vCPUs, existing machines continue running but the cluster refuses new machines until capacity is reduced or a paid license key is installed. Installer code is Apache-2.0, but downloaded boxd binaries/images are separately licensed under PolyForm Internal Use with restrictions: personal use and a company's internal operations are permitted; redistribution is prohibited. Workers require KVM/nested virtualization; clusters send hourly usage telemetry.

Requires your own VPS/server, Docker 24+, Docker Compose 2+, domain/DNS for public apps and open ports; VPS, storage, bandwidth and optional NVIDIA AI API costs are not included. Protect privileged Docker and database access.

Requires your own compatible bare-metal servers, disks, networking and operations: Harvester does NOT provide any free hosted virtual machine, bandwidth or cloud credits. Enterprise services/support, hardware and hosting incur separate costs; Apache-2.0 license terms apply.

This is self-hosted virtualization software, NOT a free hosted VPS or cloud compute allowance. Supply and pay for host hardware, storage, networking and operations. Protect daemon socket and remote API because local socket access grants host-level control. Optional commercial support is paid.

Free software only: no VPS, VM, hosting, storage or bandwidth included. Requires your own Docker/Compose host, PostgreSQL and HTTPS reverse proxy; infrastructure costs apply. Change seeded default credentials and secrets before deployment. Upstream README says MIT but actual LICENSE file is GPL-3.0; follow LICENSE and review obligations before redistribution or commercial integration. Monitoring and integrations include roadmap items, not all shipped features.

KubeVirt is a self-hosted VM orchestration component, NOT a free public VPS or a hosted cloud allocation. Requires an operational Kubernetes cluster, virtualization-capable nodes, storage, networking and platform expertise; those costs remain yours.

Requires your own physical servers, CPU, RAM, storage, networking and administration; this is NOT a free cloud-hosted VPS. The no-subscription repository lacks the tested Enterprise Repository, and commercial support and enterprise updates require paid subscriptions. AGPLv3 license obligations apply.

Free software only: no VPS, compute, bandwidth or hosting is included. Requires an existing Linux server and SSH credentials; remote infrastructure and any third-party services may incur charges. Project is early-stage; validate security and compatibility before production use.
