What is sem?
sem is a semantic version control tool that works on top of Git. It parses code with tree-sitter across 28 languages and diffs at the level of functions, methods and classes instead of lines, with blame and impact analysis. It works in any Git repo with no setup and offers an MCP integration for coding agents.

Pros: what sem does well
- Shows which functions and classes changed, not just lines
- Works in any Git repo with no setup
- Apache-2.0 licensed with 3,000+ stars
Cons: where it falls short
- Cloud-backed queries are optional and opt-in
- Command-line tool; takes some learning
Who sem is for
Developers and coding-agent users who want clearer diffs and impact analysis.
Who can skip it
People who rarely use Git.
