Log Clusterer - Group Repeated Log Patterns
Paste raw log lines and instantly cluster repeated patterns using TF-IDF and DBSCAN - runs 100% in your browser via WebAssembly.
How to use
- 1
Paste log lines
Paste raw log output or upload a .log/.txt file.
- 2
Click Cluster Logs
The WASM engine groups similar lines using TF-IDF and DBSCAN.
- 3
Inspect clusters
Expand each cluster to see representative lines and sample occurrences.
Why use this tool?
- Groups repetitive log noise into actionable clusters
- Runs entirely client-side - no log data leaves your browser
- Handles thousands of lines in seconds via compiled Rust WASM
Frequently asked questions
- What algorithm does this use?
- TF-IDF vectorization followed by DBSCAN. Epsilon is auto-estimated using a k-nearest-neighbour elbow method - the gap between tight same-pattern lines and scattered noise sets the threshold automatically.
- Is my log data sent anywhere?
- No. All processing runs in a Web Worker using WebAssembly compiled from Rust. Nothing is uploaded.
