Voltage
Lightning nodes and Bitcoin infrastructure as a service — spin up a node without running hardware.
Voltage runs Lightning nodes and Bitcoin infrastructure as a service, so developers and businesses can spin up a production node in minutes instead of provisioning and maintaining hardware. It handles the operational side — uptime, updates, backups — behind an API and dashboard.
The appeal is speed to a reliable node for apps, payment flows and experiments; the trade-off is that a hosted node is not the same as running your own metal, so sovereignty maximalists will still self-host. For teams whose product is the app on top of Lightning, letting Voltage own the plumbing is often the right call.
