Node Binance Trader NBT
Cryptocurrency trading strategy & portfolio management development
By default the trader tries to trade with margin, so you need to have at least 0.001 BTC in your spot as well as your margin account. Also, to cover trading fees, you'll need a small amount of BNB in both your spot and margin wallets. While the Bitcoin vs. Altcoins website itself is closed source, the automated trading bot called Node Binance Trader (NBT) is open source. It connects to your Binance account via the Binance API and executes the trades on your behalf. Choose any unique name you like and enter a region. You will then need to retrieve your Binance API keys from Binance. They will need to allow trading and margin wallet access. Heroku only gives dyno's on its free tier 550 hours of run time per month. This is just short of what you will need to keep your new trading bot up and running 24/7. But by simply adding your credit card to your Heroku account your allowance is extended to 1000 hours, which is plenty. -

Jesse
An advanced crypto trading bot written in Python
Jesse is an open-source AI agent framework designed to help developers build and orchestrate intelligent workflows that combine large language models (LLMs) with external tools, automation logic, and real-world actions. It acts as an agent manager where you can define tasks, contexts, and tool integrations so that AI reasoning is reliably connected to deterministic procedures like API calls, data retrieval, and task execution. Jesse emphasizes structured outputs, safety boundaries, and explainable reasoning, helping users design agents that don’t just hallucinate responses but can coordinate steps, validate conditions, and interact with systems predictably. It also includes built-in support for evaluation, logging, and orchestration so developers can monitor, test, and improve agent behavior over time. Because it’s framework-agnostic with respect to model providers, Jesse can work with different LLM backends, giving teams flexibility in cost and capability trade-offs. -

TradingVue.js
Hackable charting lib for traders. You can draw literally anything
TradingVue.js was a hackable charting lib for traders. You could draw literally ANYTHING on top of candlestick charts. If you create trading software, this lib is probably for you. If you like to make custom indicators and think out of the box, this lib is most likely for you. And if you miss the usability of TradingView.com in other open-source libraries and can't stand it, you are definitely in the right place! The process of adding a new indicator is simple, first you define your own data format (should be timestamped though) and display settings. Customizable colors and fonts. Quite fast (works even with 3 mil candles). Scripts (make your own indicators). Simple API for making new overlays. Custom drawing tools. Non-time based charts (e.g. Renko). -

Blockstack Browser
The Blockstack Browser allows you to explore the Blockstack internet
Today we are proud to announce the Blockstack browser, which allows developers everywhere to access a whole new internet. This new internet changes the dynamic and brings the power back to the people. Developers can build apps on this new internet by downloading the Blockstack Mac or Linux app (Windows coming soon) and by using nothing more than existing browsers like Chrome or Safari or Firefox. Blockchain technology powers this new internet. For the first time ever, you’ll be able to access people, communities, apps, and services built on the blockchain from your browser. This new internet reflects how people interact with each other naturally, as they have for thousands of years. In open marketplaces and societies, people transact directly with other people to offer advice, goods, and services. Human interaction has never needed a middleman. The internet should work how real life works.
