FALLEN-8 CLOUD · PRICING

Free is not a tier. It is the whole engine.

Fallen-8 is MIT licensed and free to self-host, with nothing held back: the same engine, the same REST API, the same MCP server, the same F8 Studio, and the full C# query surface. Fallen-8 Cloud is the managed offering for teams who would rather not run it themselves. It is in development, so what follows is what the tiers will include, not an order form.

Nothing on this page is billable yet. There is no checkout, and no account to create.

TALK TO US

The instance runs where you need it to run, and we still operate it.

  • Everything in Team
  • Placement of your choosing: sovereign European cloud, your own data centre, air-gapped
  • A dedicated model sidecar on request, so document text never reaches a shared process
  • Data processing agreement, service level agreement, named support
  • Federated sign-in from your own identity provider

HOW BILLING WILL WORK

Priced on RAM, because that is what a graph in memory costs.

Fallen-8 keeps the whole graph in memory. RAM is therefore the only honest size dimension, and it is the one you will be charged for. The rest is deliberately not metered.

Size is RAM, billed by the hour the instance runs
You pick an instance size and pay for the hours it exists. Stop it and the meter stops.
Queries are not metered
No charge per traversal, per analytics run, or per agent tool call. Your queries are bounded by the RAM you already paid for, and metering the fastest thing the engine does would be a strange way to price it.
Namespaces are included, up to a stated cap
One instance holds many isolated graphs, each with its own indexes, subgraphs and change feed. That is a capability, not an upsell. It is capped rather than unlimited, because each namespace is a real engine with its own writer thread, and we would rather tell you the number than pretend there is not one.
Quoted in EUR, with VAT where it applies
Prices will be published before the console opens. Nothing will be charged before you have seen them.
WHY THERE IS NO FREE HOSTED TIER

Because the free version is better than one would be.

A free tier on our servers would have to be small, shared with strangers, and locked down: no C# fragments, because a Fallen-8 query is C# compiled and run inside the server process, and that is only safe when the process belongs to one tenant. Self-hosting has none of those limits. You get the whole engine, on your own machine, with no account and nothing reporting back.

So free stays where it is already unbeatable, and Fallen-8 Cloud sells the part self-hosting cannot give you: somebody else runs it, backs it up, restores it, and answers when it breaks.

Want to try the engine without installing anything? The playground runs Fallen-8 compiled to WebAssembly, entirely inside your browser tab. No account, no server allocated to you, and your data cannot leave your machine because there is nothing to send it to.

FALLEN-8 CLOUD · COMING SOON

Tell us to tell you.

The console is where you will create and manage instances, and it is not live yet. Sign-in, instance management and billing ship together with the hosted offering. Fallen-8 Cloud is how the project sustains itself; the engine stays MIT licensed and free to self-host either way.
