DonjaBot

Editions

One engine, wired for your exchange.

Getting started

Buy once, and it's yours.

Your licence key and the download appear together the moment you pay — one page, nothing to hunt for afterwards.

How buying works

Pay once for the edition you want — $30 for Kalshi, $50 for Kraken. No subscription, no account to create.
Your licence key appears on screen, with the download for your machine right beside it.
Install it, paste the key in once, and you're running.

Works on up to three of your own computers. Updates are included and the app installs them itself.

System requirements

macOS 10.15 (Catalina) or later — Apple Silicon or Intel
Windows 10 or later, 64-bit
An internet connection
Your own Kalshi or Kraken account (whichever edition you buy), and an API key you create there

On Windows you may see a warning that the publisher is unrecognised, until enough people have downloaded a release. That warning is expected and we would rather say so than have it surprise you.

Already bought and need the app again — new computer, fresh install? Download DonjaBot for Kalshi for Mac (Apple Silicon), Mac (Intel) or Windows, or DonjaBot for Kraken for Mac (Apple Silicon), Mac (Intel) or Windows. Your existing key still works. Not sure which Mac you have? Apple menu → About This Mac; a chip named M1, M2, M3 or M4 means Apple Silicon.

How it works

Three steps, then it runs on its own.

No account with us, no server of ours in the middle. The app talks directly from your computer to your exchange.

STEP 01

Connect your account

Create an API key at your exchange and paste it in. It stays on your computer — or on your own server, if you choose to use one — and goes only to your exchange, never to us.

STEP 02

Set your rules

Choose which markets to watch, what edge to require, how much to stake, when to take profit and when to cut. Tune it, then apply.

STEP 03

Let it work

It scans, places orders, and manages exits while you're asleep or busy. Pause or stop it from the sidebar at any time.

What you get

You configure it. It doesn't decide for you.

Practice with play money. A built-in simulation mode runs the same engine against the same live data, with a fake balance — so you can try settings before risking anything real.
Every knob, in plain English. Stake size, profit targets, stop levels, which sports or coins to watch, and when it is allowed to act.
Save your own setups. Build a configuration, name it, switch between them.
See what it's doing. Live dashboard, open positions, full trade history, equity curve, and the raw log if you want it.
It tells you when trading breaks. If orders start failing, a banner says so instead of the bot quietly doing nothing.
Updates arrive in the app. When an exchange changes something, the fix reaches you as an update you click, not a download you have to hunt for.
Your keys stay yours. No accounts, no telemetry, no analytics. We never see your balance, your trades, or your key.

Straight talk

The part most sites leave out.

Plenty of trading software is sold with a chart going up and to the right. We would rather you knew exactly what you are buying, and what it cannot do, before you spend anything.

You are in control, not us. We do not know you, your account, or your finances, and nothing in the app is a recommendation. You choose the strategy and the settings — which is the point, and it also means the results are yours.
We do not publish performance numbers. Not here, not anywhere. Any figure quoted for a trading bot is a figure someone chose to show you.
Trading can lose money, and a bot can lose it while you sleep. That is the trade-off for software that works when you are not watching, and it is worth understanding before you switch it on.
Simulation is a rehearsal, not a promise. It assumes fills a live market may not give you, so it can look better than live trading does. Use it to get your settings right, not to predict what you will make.
Software meets the real world. Connections drop, exchanges change their interfaces, and bugs happen. A stop-loss is an instruction to place an order, not a guarantee. That is exactly why the app tells you when trading breaks, and why fixes reach you as an in-app update.
We are not registered as an adviser, broker, or trading advisor, and we do not act as one. This is a tool you operate.

Trade only with money you can afford to lose entirely. That is the one rule that matters. Start small, use simulation to get your settings where you want them, and scale up only when you are comfortable with what it is doing.

Before you buy

System requirements.

There's no free trial, so please check this list first. If it won't run on a supported machine, we'll refund you.

macOS: macOS 10.15 or later. Apple Silicon and Intel.
Windows: Windows 10 or later, 64-bit.
Exchange account: Your own funded account, and an API key you create. Not included. Kraken doesn't serve every US state — check yours before buying the Kraken edition.
Internet: A connection that stays up. The bot can't manage positions while offline.
Left running: The bots trade only while the app is open — or on a server you rent yourself, if you use Run on a server. Nothing runs on ours.

Questions

Fair questions.

Do you ever see my money or my API key?

No. Your key is stored on your computer — or on your own server, if you use one — and sent only to your exchange. Your funds stay in your own exchange account — we never hold, receive, or have access to them. There are no accounts with us at all.

Why does Windows warn me when I install it?

New applications build reputation with Microsoft over time. Until enough people have downloaded a release, Windows may show a warning even for properly signed software. It goes away as the release ages.

Can I try it before buying?

Not before buying, no — each edition is a single purchase: $30 for Kalshi, $50 for Kraken. Simulation mode is included once you own it, so you can test settings with play money before going live. And if it won't run on a supported machine, or doesn't do what this page says, we'll refund you.

What happens when the exchange changes something?

We ship an update and your app offers it to you. That channel exists because it has happened before — an exchange retired an endpoint and trading stopped until it was fixed. Without an update channel, a change like that would have bricked every copy permanently.

Do I need to know how to code?

No. Everything is sliders, number boxes and plain-English labels. You never see or write any code.

Is Kraken available where I live?

Kraken doesn't serve every US state, so check that you can open and use a Kraken account before you buy the Kraken edition — that's where you create the API key the app needs.

Does the Kraken edition trade futures or use leverage?

No. Live trading is spot only: it buys and sells coins in your own account, and never borrows. The futures and leverage settings you'll see in the app work in the simulation only.

Can I run more than one edition at the same time?

Yes. They're separate purchases and separate apps, each with its own licence key, settings and history. A key for one edition doesn't unlock another.

Is this affiliated with Kalshi, Kraken or Polymarket?

No. DonjaBot is an independent product. Those names identify which exchange each edition connects to; nothing here is endorsed by or affiliated with them.
