One package for all trading needs across Web2 and Web3

Every model needs to figure out how to buy and sell. We make it super easy for you so you can focus on building better trading algos. Your models can run on any platform, and on any supported exchange. We make that as easy as just changing one line of code.


Quickly & accurately simulate your models over time.

"What I enjoy most about Blankly is how quickly I can go from an idea to backtesting to then executing on it in live or paper trading. Prior to Blankly, my workflow was disorganized, spanning various notebooks and helper code. With Blankly, I don't have to worry about how to put something into production - just flip a parameter and get going."

- Stefan Hermaneck

Instead of spending months building and testing my own trading engine, I installed the Blankly package and had a trend-following strategy up-and-running within a matter of hours. I was able to use that time to focus on what matters: researching, testing, and iterating on strategies. Additionally, since the package is open source I am able to dig through the code to verify it is performing as expected, or add new features so it fits my specific needs.

- Jake Kalish

  • "This is a incredible piece of work, the website is beautiful, very clear docs, the code is nice and modular. takes the nitty gritty bits out of making algos."

  • This is impressive. Really great work, I love the compatibility with multiple exchanges and the overall structure. Can't even praise the backtesting feature enough. I'm currently diving into the docs to really learn it and hopefully apply to my own strategy.

  • Holy ****, really Nice project!

Frequently asked questions

Why did you create Blankly?
Blankly started out of our own struggles building programmatic trading algorithms. It took us months to just gather the data needed, another month to build the model, and another few months just to figure out how to deploy it. With Blankly, we take that process and make it just a few lines of code. We want to make what we've learned over time and make it available for everyone.
Is Blankly Open-Sourced?
Yes, all of Blankly is open-sourced, definitely check out our Github and submit a PR. We're continuously making more and more improvements as we go. We are the first to support live exchanges as we build out more exchange connections. So definitely check out our github for the latest updates and releases.
What can you do with Blankly?
We're making it super easy for you to build one trading bot that runs LIVE on any exchange. We give you the tools and the ability not only to trade, but also backtest your model and optimize for you to make the best models out there. We're not trying to sell you our specific trading bot. Check out this YouTube Video for an example
So is this just connecting multiple APIs?
We started out just doing that: making it easy to connect to Coinbase Pro and Binance. We soon expanded to multiple assets and exchanges. However, Blankly really shines not just in trade execution, but also model backtesting in one line, with custom data, and deploying to optimized cloud infrastructure. We're streamlinining the entire workflow, and not just the trading.
How do I get started?
All you have to do is install our package and check out our getting started docs! It's as simple as that. Easily run backtests on our Blankly Platform for free (Join the Waitlist).
Can I integrate an existing model?
Yes, Blankly allows for easy and quick iteration. I built a genetic algorithm to trade stocks in the past and integrated it with Blankly within minutes. We make it super easy to integrate for any exchange.
