ToolEka

ToolEka is a collection of 14 free browser-based utilities for finance, developer, health, text, and date tasks. It addresses the need for quick calculations and conversions that run entirely client-side without accounts, data uploads, or external servers.

The finance section includes an EMI calculator that produces an amortization schedule for loans, a loan calculator showing total interest and repayment timelines for fixed-rate loans, and a VAT calculator that adds or removes tax using custom or standard rates. Developer utilities comprise a cron expression generator with human-readable previews and systemd timer conversion, a JWT decoder and generator for inspecting and creating signed tokens, an API request tester supporting GET, POST, PUT, and DELETE methods with full response inspection, and a JSON to YAML converter for bidirectional instant transformation. Additional categories cover health metrics, percentage calculations, text formatting tools, and date and time utilities. All processing occurs 100 percent in the browser, delivering instant results with no installation required.

The tools are designed for developers and general users seeking privacy-focused utilities. Delivery is exclusively through the web at tooleka.com, where each utility loads and executes locally. The service is always free with no accounts or tracking.
