What is CapyToolkit?
CapyToolkit is a collection of 45 free browser tools engineered to run entirely client-side. All operations execute locally via native browser APIs, Web Workers, and WASM, ensuring that data, logs, and cryptographic keys never reach an external server.
The catalog covers:
- Hardware Diagnostics: Fullscreen dead-pixel checking, gamepad drift inspection, mouse polling rate testing, and audio latency measurement.
- Developer Parsers: Local JSON formatting, JWT decoding, regex debugging, and running offline SQL queries over local Parquet or CSV files using DuckDB WASM.
- Security Utilities: EXIF metadata removal, automated PII scrubbing, and offline document text redaction via Tesseract WASM.
The platform requires no user accounts, is fully functional offline as a PWA, and explicitly blocks analytics scripts within all tool areas.
