What makes it different to all the other generic “run Claude Code while you sleep” ideas is the insight that every developer works differently, and rather than a generic agent or plan that gives you mediocre, generic results, the manager/supervisor AI should behave the way you would’ve behaved and tried to continue like you to focus on the things you would’ve cared about.
The first time you run Overnight, it’ll try to scrape all your Claude Code chat history from that project and build up a profile of you as well as your work patterns. As you use Overnight and Claude Code more, you will build up a larger and more accurate profile of how you prompt, design and engineer, and this serves as rich prediction data for Overnight to learn from execute better on your behalf. It’s designed so that you can always work on the project in the day to bring things back on track if need be and to supplement your workflow.
The code is completely open source and you can bring your own Anthropic or OpenAI compatible API keys. If people like this project, I’ll create a subscription model for people who want to run this on the cloud or don’t want to manage another API key.
All of overnights work are automatically committed to new Git branches so when you wake up, you can choose to merge or just throwaway its progress.
It is designed with 4 modes you can Shift Tab through depending on how adventurous you are feeling:
1. tidy — cleanup only, no functional changes. Dead code, formatting, linting. 2. refine — structural improvement. Design patterns, coupling, test architecture. Same features, better code. 3. build — product engineering. Reads the README, understands the value prop, derives the next feature from the business case. 4. radical — unhinged product visionary. "What if this product could...?" Bold bets with good engineering. You wake up delighted or terrified. Hope you like this project and find it useful!
