Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

An infinite canvas for code exploration
It's unclear what the superpowers would be? Video doesn't show anything I can't do with an IDE or decent code editor, and there I also have refactoring tools, metadata like indicators for usages that can be used for navigating and so on.
Reminds me of UML-like diagrams over relational databases, except that it's generated one piece at a time. In practice I generate diagrams showing cyclomatic complexity much more often, and for code exploration outside the IDE I'd use ast-grep.

How I build a chatbot for my OSS project, for free, without code!
ast-grep is a command-line tool that lets you search and transform code written in many programming languages using abstract syntax trees (ASTs). ASTs are data structures that capture the syntactic and semantic structure of source code. With ast-grep, you can write patterns as if you are writing ordinary code, and it will match all code that has the same syntactical structure. And if you need more power, you can use YAML, a rule system that allows you to write more sophisticated linting rules or code modifications.

AST-grep(sg) is a CLI tool for code structural search, lint, and rewriting
I really like this - it means the tool is available to people with familiarity of any of those four distribution mechanisms.
You can also download pre-built binaries from their releases page: https://github.com/ast-grep/ast-grep/releases/tag/0.14.2
On top of that, they offer API bindings for it in three different languages:
- Rust (not yet stable): https://docs.rs/ast-grep-core/latest/ast_grep_core/
- JavaScript/TypeScript: https://ast-grep.github.io/guide/api-usage/js-api.html
- Python: https://ast-grep.github.io/guide/api-usage/py-api.html
It's rare to see a tool/library offer this depth of language support out of the box.
