FallKard turns the tools you use into something you actually own. Get a kard, open it, and your own workspace appears — on your machine, in a look you choose. No account. No monthly rent. If the company behind it vanishes, your kard still opens.

Software you own, not software you rent
Almost every tool you use — your dashboard, your CRM, your forms, your workspace — was built once and then rented to you: the same look for everyone, running on someone else's server you pay for every month. FallKard flips it. The tool is still built once — but your copy is yours.
What you get
Your workspace. Your world. Your rules.
Your kard is like a save file for a tool that's yours. Open it and the whole workspace loads on your own machine, in a look you picked, remembering your stuff. It never has to be rebuilt or re-hosted for each person — one build, worn a thousand ways. Sign in to nothing; nothing phones home.
You're not a tenant on someone's platform
You hold the key. The tool opens for the identity your kard names — and only that identity can sign it.
Change the whole look in one click
The tool underneath stays the same; the skin over it is entirely yours to swap. See it live in the locker below.
The expensive half this deletes
An alternative to the costly parts
FallKard is an alternative to the parts of software that cost the most and add the least:
The bespoke front-end rebuilt from scratch for every client or brand — what agencies charge a fortune for.
"White-label" theming sold as a premium add-on, per tenant.
Per-seat hosted tools billed every month whether you use them or not.
The stack of separate subscriptions that each do one small thing.
Per-customer hosting and uptime you pay for so a vendor doesn't have to.
One build. Skinned per person. Hosted by no one but the owner.
For agencies & solo builders
Build the tool once. Hand each client their own skinned copy that opens on their machine. No rebuild, no re-host, no per-tenant theming bill — the skin is a file, not a project.
For individuals & owners
Your own tools that look like yours and outlive any vendor. Everything runs on your device. If the company behind it disappears, your kard still opens and your workspace is still there.
01
The loop, for real
This isn't a mock-up. Pull a kard and it's forged in your browser, right now. Open it and your node wakes up. Try to cheat its spending cap and watch the wall hold. Everything here runs on your device.

1
Pull your kard
mint · a signed identity is forged
Forge a brand-new kard, signed only to you. Nobody else can make this one.
2
Open it → your node wakes up
open · verify the signature, summon the node
Opening checks the kard is really yours and untouched, then brings your node online. Try tampering with it first — the check catches it.
3
A cap that can't be crossed
budget wall · enforced, not decorative
Every kard carries a hard spending cap. No trick, no re-sign, no caller can push a node past it.
4
It runs light
cheap · a counted number, not a claim
Your node only draws what you're actually looking at, and reuses what stays on screen. Here's the saving, counted over a real usage path.
02
Pick your look
Here is the same workspace — the exact same node — wearing two different skins. Not a colour swap: a whole world each. Change the type, the layout, the mood in a click. Konomi builds what the workspace is; the skin over it is entirely yours. Set each side to any world and see for yourself.
Face A—
Face B—
Sample workspace + demo data, rendered live in your browser — no backend, nothing sent anywhere. The conversation replies are scripted, not a live model.
03
Every piece is one system
FallKard isn't one app — it's the front door to a whole estate of tools, each an organ of the same flow. The kard is the spine; a re-runnable trust rail runs underneath all of it. Every stage below is live — open its organ.
00
Prove it
Nothing here is taken on trust — every claim is re-runnable proof, checked by a machine, not an opinion from a model. This rail runs under every stage below.
Your look, your memory that learns from your work, your workspace shape. The tool bends to you — not you to a fixed interface.
It runs light
It draws only what you're looking at and reuses what stays on screen, on your own hardware. Tailored and cheap at once — usually a trade-off, here both.
It's yours
Signed to you, owned by you, verifiable by anyone. No account, no lock-in, no server holding your data hostage.
It joins up
Each kard is a node. Many kards make a personal network you enter one kard at a time. FallKard is the on-ramp.
Straight about what's real
The pieces exist — FallKard composes real organs of the estate, live and linked below.
"Runs light" is measured, not claimed — the number above is counted work, with the trick vs without.
The spending cap is real and enforced. Selling kards or skins waits until the money side is set up properly.
The full network is the next layer. Today a kard is a real, verifiable node you own; node-to-node federation is being built on top.
Under the hood · for builders
Ed25519 — each kard is a self-sovereign signed identity; only the key it names can sign it.
spendGate — the uncrossable budget wall, enforced in the gated kernel.
Witness-gated — kard + flow kernels, mutation-proven, no LLM judge.
Kernel-backed page — this page inlines the exact gated kernels; the logic you run is the logic the gate proves.
cheapVerdict — counts render operations over a real usage path, with vs without. Reproducible.
Client-side — no backend, no accounts; every keypair and render happens on your device.

Questions
What is FallKard, in plain terms?
A kard is like a save file for a tool that is yours. You get one, open it, and your own workspace appears — on your machine, in a look you choose. No account, no monthly rent, and nothing leaves your device.
What does it replace?
The expensive half of software: the bespoke front-end rebuilt per client, per-tenant white-label theming, per-seat hosted subscriptions, the stack of monthly tools, and per-customer hosting. One build, skinned per person, hosted by the owner.
Who is it for?
Agencies and solo builders who rebuild the same tool for every client — build once, hand each client a skinned copy, no re-host — and individuals who want tools that look like theirs and outlive any vendor.
Is my data sent anywhere?
No. Everything runs client-side in your browser: every keypair and every render happens on your device. There is no backend and no account.
What is a kard, technically?
A portable, signed identity: an Ed25519 owner key plus a skin reference, a structure reference, a capability set and an uncrossable budget. Opening it instantiates your node, and only the identity it names can sign it.
How is "runs light" measured?
By counting render operations over a real usage path — rendering only what is in view and reusing what stays, versus rendering everything every step. The number on the page is that count: reproducible, with no LLM judge.
Can a node spend past its budget?
No. The budget wall is enforced in the witness-gated kernel — no capability, no signature and no caller can raise the ceiling a kard was minted with. Selling kards or skins waits behind counsel.
