Three developer tools worth your attention today
Oak: Version control built for AI agents
Oak is a new project that scored 148 points on Hacker News. Its pitch is straightforward: a version control system designed specifically for AI coding agents, replacing Git.
Why do agents need their own VCS? Git was designed for humans — interactive rebases, complex merge strategies, commit message conventions. AI agents don't need any of that. Oak strips out the human interaction layer and keeps what agents actually need: auto-commit, branch management, and code collaboration.

DELN: An interactive atlas of AI training datasets
DELN does one thing well: it visualizes the training data sources, scale, and composition of major AI models in an interactive atlas.
Researchers often need to understand what data a model was trained on, but this information is scattered across papers and technical reports. DELN consolidates it into a single browsable interface. You can filter by model, data type, or source institution and compare training data differences between models.
Two types of people will find this useful: researchers doing model evaluations who want to understand the data behind benchmarks, and enterprise users assessing model data quality during vendor selection.

FastAPI Cloud: Official cloud deployment from the FastAPI team
FastAPI is one of the most popular Python backend frameworks. Now its creator Sebastián Ramírez has launched FastAPI Cloud, an official deployment platform currently in public beta.
Before this, deploying a FastAPI app meant setting up servers, configuring reverse proxies, and handling scaling yourself. FastAPI Cloud takes care of all that — push your code and it handles deployment and operations automatically. Small teams and solo developers save a lot of hassle.
The public beta is open for signups at fastapicloud.com. If you're already using FastAPI for your backend, this is worth keeping an eye on.
