About DevKitBase
DevKitBase is a local-first paste bench for developers: JSON, encode/decode, hashes, regex, timestamps, and related utilities in an IDE-style shell — light or dark, six languages, no signup.
What it is
Pick a tool from the sidebar, paste input, get output. Transforms run entirely in your browser tab using Web APIs and small client-side helpers.
Nothing you paste is uploaded as part of the tool workflow. Theme and language preferences may use localStorage on your device.
Who it is for
Engineers, QA, and anyone who needs a quick formatter, decoder, or checksum without opening a throwaway SaaS paste site.
What it is not
Not a security product. JWT decode does not verify signatures. Hashes are for debugging and checksums — not password storage advice.
Not affiliated with other *Base money or insurance calculator sites that may share a similar naming pattern.
Runs in your browser. Nothing is uploaded. Not a security product —hashes and JWT decode are for debugging, not password storage or auth advice.
