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. -

Crypto Arbitrage
A cryptocurrency arbitrage opportunity calculator
A cryptocurrency arbitrage opportunity calculator and trading bot. Over 800 currencies and 50 markets. In short, it collects JSON from multiple different cryptocurrency markets, goes through the results, and finds the highest and lowest price for each coin. The script will find the highest price (chbtc.com), and lowest price (Bittrex), and divide the two: 51.8/38.23 = ~1.35 (~35% profit margin) and then push these results to the browser. It will also find the next highest market pairs, e.g. chbtc / jubi is the second-highest pair and chbtc/Bittrex the third, jubi/Bittrex the fourth and so on until every possible combination has been computed. Currently you will have to add a market object with the correct settings in the array markets, situated in the settings.js file. I am updating the project every day and this will change soon. You can temporarily stop loading a market from the frontend, or remove the market by deleting the object in settings.js. -
