How lean-ctx
Compares
No marketing spin. A straightforward look at what lean-ctx does better, what it does the same, and when you don't need it at all.
Feature Comparison
See how lean-ctx stacks up against working without tools or with manual context rules.
| Feature | No Tool | Manual Rules | lean-ctx |
|---|---|---|---|
| Token Savings | None | Low (static rules) | 60–95% (cached: 99%) |
| Setup Effort | None | Manual per-project | One command |
| Agent Support | N/A | One agent only | 29+ agents |
| Caching | None | None | Automatic + delta |
| Shell Compression | None | None | 95+ patterns |
| Code Analysis | None | None | Tree-sitter AST |
| Maintenance | None | Manual updates | Automatic |
When lean-ctx Shines
lean-ctx delivers the most value in these scenarios.
Large Codebases
Projects with hundreds or thousands of files benefit most. The more context there is to manage, the bigger the savings.
Multi-Agent Workflows
When multiple AI agents work on the same project, lean-ctx provides consistent, compressed context across all of them.
Iterative Development
Long coding sessions with repeated file reads hit the cache - re-reads cost just ~13 tokens instead of thousands.
When You Don't Need It
We believe in honest tooling. lean-ctx is designed for projects with substantial codebases - not everything.
- Single-file scripts or small utilities
- Projects under 50 files
- One-off prompts without file context
In these cases, the overhead of a context layer isn't justified. lean-ctx shines when your projects grow and context management becomes a bottleneck.
Measured Performance
These numbers come from real-world usage across projects of varying sizes.
