DebugKit — Swiss-army knife for scraping

JWT, Base64, regex, and JSON debugging in one fully offline panel

Problem

A developer with years of scraping experience complained about constantly bouncing between random online tools: decoding a JWT returned by an endpoint, cleaning up Base64 hashes, testing regexes against a page structure that changes every other month. The biggest frustration was not knowing where the pasted data went. Existing debug tools are either online or scattered.

Solution

A fully local browser-based developer panel that combines decoders, formatters, regex testers, and field extractors into composable workspaces. Users can save the current page structure as a debug sample and reuse it next time without re-pasting. Everything runs client-side.

Users

Indie developers doing web scraping, data engineers, and crawler developers who frequently handle API responses.

MVP

JWT decode, Base64 encode/decode, JSON pretty-print and diff, live regex tester; all processing in-browser with zero upload; paste or drag-and-drop files; save tool combinations as workspaces; local history.

Revenue

Free local version as lead magnet; paid one-time or subscription for workspace sync, team-shared snippets, CLI version, and batch processing.

Why now

Scraping and API debugging remain daily high-frequency work, yet generic online tools have privacy concerns and are fragmented. Client-side compute is now fast enough for a privacy-first, no-signup debug panel.
