DevTooling brings everyday developer utilities into one free workspace. Run XSLT 1.0–3.0 transformations; format, validate, convert and compare XML, JSON, YAML, CSV and EDI; work with PDFs; and build cron expressions. No signup or installation required. Most tools run entirely in your browser, keeping your data on your device.
Hey Product Hunt! I built DevTooling.net, because I kept bouncing between a dozen different sketchy single-purpose converter sites for XML/JSON/EDI work, most stuffed with ads or quietly uploading data to who-knows-where.
DevTooling is 23 tools in one place — formatters, viewers, XML↔JSON↔CSV↔YAML converters, diff tools, an XSLT compiler with precise error reporting, an EDI viewer, JWT decoder, cron generator, and a lossless PDF toolbox. Every tool except the XSLT compiler runs entirely client-side — your data never touches a server.
Would love feedback on which tool is most/least useful, and what's missing from the suite!
