A good backtest is easy.
An honest one isn't.
Vectaris is a browser-based trading workspace for stocks, options, crypto, futures, and event contracts. Take a strategy from idea, through walk-forward validation, to live execution on your own broker accounts. The code you backtested is the code that trades.
Free tier, no credit card, no install.
Software, not signals.
We don't tell you what to trade. You bring the strategy; Vectaris validates it and runs it. Every rule it follows is one you wrote.
Your account, your credentials.
Orders execute in your own brokerage accounts. Vectaris routes the instruction; your broker holds the money.
Your data stays yours.
No trackers. No ads. Nothing sold. The AI assistant runs on your own API key.
One screen. Every account.
Nine brokers, five asset classes, one portfolio. Paper trading and CSV import included.
The short list.
Live Deployment
Deploy a validated strategy to your own broker account and it trades the exact code you backtested. Paper is the default; going live takes a typed confirmation plus required limits on session loss, position size, and order rate. A kill switch sits on the toolbar, and strategies run while your workspace is open.
Walk-Forward Validation
Backtest against history, then walk forward through data the strategy has never seen. Overfit strategies fail here instead of in your account.
Multi-Broker Trading
Schwab, Tradier, Alpaca, Coinbase, Kraken, Hyperliquid, Tradovate, Kalshi, and Polymarket. One order ticket and one portfolio across stocks, options, crypto, futures, and event contracts.
Options Chain & Greeks
Live delta, gamma, theta, vega, IV, and a volume/OI heatmap, per contract. Build the spread and send the order without leaving the chain.
Free Means Free
DOM, charts, options chain, portfolio, time & sales, order designer, backtest lab, and AI chat are all on the free tier. Nothing to install and no data fees, because it runs in the browser.
Inside the workspace.
Full workspace
Charts, DOM, options chain, portfolio. Arrange them how you trade; the layout holds.
Options chain & Greeks
Live Greeks, IV, and volume/OI heat for every contract in the chain.
Order designer
Single legs, spreads, protected orders. Designed once, routed to your broker.
Live deployment
Mode, status, and session P&L for every running strategy. Pause one, or kill all of them at once.
Analysis, not advice.
An AI assistant sits in the workspace. Ask it about the market in front of you and it answers from real data.
Bring your own key.
The assistant runs on your API key. Prompts go to your AI provider, never through our models, and never into training.
Grounded in market data.
It works from the platform's own market-data tools: the same quotes and history that feed the charts.
You confirm every order.
It can draft an order; it cannot place one without you. Every trade is yours.
Sealed on arrival.
A broker key is the most sensitive thing you can hand a trading platform. Here is exactly what happens to yours.
One credential, end to end
The ciphertext and the key that opens it rest on two different systems. Neither one is enough on its own.
Sealed the moment it lands.
Each credential is encrypted with AES-256-GCM under a nonce of its own and bound to your account, so a copy lifted into another row or another user no longer opens.
Two systems, two secrets.
The ciphertext sits in the database. The key that opens it is injected into the API as a deploy secret on a different provider. Reading the table gets you nothing.
You choose where it lives.
Encrypted in your account and synced across devices, kept in this browser alone, or not saved at all. The trade-off for each is written next to the control.
Every open is written down.
Create, decrypt, and delete each append a row to a log the application cannot rewrite. The secret is never in that log, and never in our process logs either.
Locks on the front door too.
Sign in with a password, Google, or a passkey, and add an authenticator app if you want one. The API checks the second factor itself, so a stolen password alone gets nowhere.
Delete is a delete.
Removing a connection erases the row rather than flagging it. Closing your account takes its credentials and their audit trail with it.
We also ask you to issue broker keys with trading and read permissions only, never withdrawal or transfer, and to start on your broker's paper keys. Setup says so before you paste anything. Read the Privacy Policy.

Direct answers.
Is Vectaris a broker?
No. Vectaris is software. Orders execute at your own broker, under your own credentials.
Do you hold my money?
No. Your funds never leave your brokerage. Vectaris transmits your instructions; your broker executes them.
Do you sell signals or advice?
No. The platform never recommends a position. You author the strategy; Vectaris tests it and routes it. Read the Risk Disclosure.
Can my strategy trade on its own?
Yes. A validated strategy deploys to your own broker account and trades the exact code you backtested. Paper is the default; going live needs a typed confirmation, a session-loss cap, a position cap, and an order-rate cap. Strategies run while your workspace is open, and closing the tab pauses trading.
Can I stop everything at once?
Yes. A kill switch sits on the toolbar whenever a strategy is running. One click pauses every deployment and cancels their working orders.
Is it really free?
Yes — all of it. Every module, all seven brokers, backtesting and paper trading at $0, with no data fees, no time limit, and no feature held back. There is no paid tier to upgrade to. Vectaris is paid for by people who choose to support it.
How is it paid for, then?
Voluntary one-time gifts, from people who find it useful. No subscription, no tiers, nothing to cancel, and giving unlocks nothing — because nothing is locked. Vectaris LLC is a company, not a charity, so it is not tax-deductible.
Does the AI trade for me?
No. The assistant analyzes; you decide. It runs on your own API key, so your prompts belong to you.
What happens to my data?
Nothing. No trackers, no ads, no selling. Broker credentials are encrypted and used only to route your own orders. Read the Privacy Policy.
It's free. All of it.
Not a trial, not a limited tier, not free-until-we-change-our-minds. There is no paid plan to upgrade to, and nothing is held back for one.
So how does it stay alive?
Vectaris is built by one person and paid for by the people who find it useful. If it earns its keep, you can give what you like, once. That is the whole arrangement — no subscription, no tiers, nothing to cancel.
It unlocks nothing, because nothing is locked. Giving lives inside the app, so you can see what you would be supporting before you decide. Vectaris LLC is a company, not a charity — this is not tax-deductible.
