Community Spotlight: Flux Hub, a Marketplace for Flux Nodes

Fluxers! Running a Flux node takes two things: FLUX locked as collateral, and a machine that meets the benchmarks of its tier. Plenty of people in this community have one and not the other. Some hold the collateral and have no wish to run a server at home. Others have a rack of Proxmox hardware with slots sitting idle.

Community member w2vy built something for both of them. It is called Flux Hub, and it is a marketplace for Flux nodes, made by the community, for the community.

A marketplace, not a host

Flux Hub connects people who hold FLUX collateral with independent operators who run Proxmox hardware. Operators list Cumulus, Nimbus and Stratus slots at their own price. A renter picks one, and gets a managed node.

The money never passes through the middle. The renter pays the operator directly, on the operator's own Stripe account, and Flux Hub takes no cut of a rental. The operator keeps all of what they charge.

If you hold collateral

Renting a node takes three steps:

• Pick an operator and a tier. Every card on the marketplace shows live availability and 90 day benchmarks: EPS, disk write and uptime.
• Sign in with your wallet. ZelID or SSP, with no password to create. You enter your node configuration, and the operator's agent builds an ArcaneOS virtual machine for it.
• Run it from one dashboard. Flux Hub starts the node and watches it. Status, benchmarks and billing are in one place.

Your collateral never leaves your wallet. Neither the operator nor Flux Hub takes custody of it, or of your wallet keys. What the operator's agent does receive is the node configuration you submit, identity key included, because that is what a node needs to start. It is the same for any hosted node, and the Flux Hub terms say so plainly.

Billing is a monthly subscription that you can cancel from the dashboard. Every rental starts with a trial of at least one day, so the node is built and running before the first charge.

What it costs

Operators set their own prices, so there is no single price list. These were the lowest listings on the marketplace on 30 September 2026:

• Cumulus, 1,000 FLUX collateral: 4 vCPU, 8 GB of memory, 220 GB SSD, from $3 a month
• Nimbus, 12,500 FLUX collateral: 8 vCPU, 32 GB of memory, 440 GB SSD, from $9 a month
• Stratus, 40,000 FLUX collateral: 16 vCPU, 64 GB of memory, 880 GB SSD, from $17 a month

The tier page shows the benchmark floor of each tier next to what the nodes on the marketplace measured over the last 90 days. If you are new to the tiers themselves, we covered them in what actually makes a machine a Flux node.

If you own hardware

There are two ways in, and the first one is free.

A Supporter needs no Stripe account and lists nothing for sale. You run your own nodes, and Flux Hub places Foundation nodes on the slots you are not using. It is the recommended first step, because it proves the parts that can go wrong, the Proxmox token, the agent and a node that boots, before any money is involved.

An Operator does all of that and also rents slots out. You add Stripe, set your prices and list. You are the merchant of record and the customers are yours. When a paid rental arrives, a Foundation node on that slot is moved out automatically.

The design is careful about what it asks of you. The toolkit and the agent run on your side and only ever call out. Flux Hub never holds your Proxmox or Stripe credentials, and never opens a connection into your network. You sign once with your wallet. The operator console shows your fleet, your rentals and the health of each node, with alerts about a version or a benchmark problem before a node drops tier.

Flux Hub's own income comes from operator plans, sized by how many customer rentals an operator runs at once. The entry plan is free.

Early days, and what is planned

Flux Hub is new. Today the listings come from the hardware of the team behind it, in Florida, and the whole point of a marketplace is that more operators join. If you have Proxmox capacity to spare, this is a good moment to be early.

Three things are planned, with no dates yet: token hours, to rent in blocks of hours instead of months, rentals between operators for a maintenance window or a burst, and host telemetry in the console.

A community project

Flux Hub is independent. It is operated by MoltenTech LLC, not by the Flux team, and a rental is an agreement between you and the operator you choose. Read the terms before you subscribe, as you would with any host.

We are writing about it because this is what we like to see: a member of the community noticing a gap and building the thing that fills it. The more ways there are to put a node on the network, the stronger the network gets.
