Developer Tools

The ToolsPix Developer Tools collection is built around the small, repetitive jobs that punctuate a developer's day — the ten-second tasks that interrupt flow but don't justify writing a script. Pretty-printing an API response before pasting it into a ticket. Stripping whitespace from a config file before committing. Decoding a Bearer token to see which user the request came from. Generating a fresh UUID for a database fixture.

Every tool here follows the same three rules: do one job well, load instantly, and never send your data anywhere. The whole site is static HTML behind a CDN, with each tool implemented as a single self-contained page. There's no build pipeline, no telemetry, no third-party scripts — just JavaScript running locally in your tab.

Common workflows

• Debugging APIs — paste a response into the JSON Formatter to spot missing fields, or into the JWT Decoder to inspect token claims
• Code review prep — beautify a colleague's minified bundle with the JS Beautifier or CSS Beautifier before reading
• Data wrangling — flip CSV exports to JSON for ad-hoc analysis with CSV to JSON, or convert YAML configs with YAML to JSON
• Schema authoring — round-trip XML through the XML Formatter to catch unclosed tags before shipping
• Identity & security — generate UUIDs, strong passwords, or content hashes without leaving the browser

Privacy by design

None of these tools have a backend. There is no server that receives your input, no log file recording your activity, no analytics endpoint counting your clicks. This isn't a marketing claim — it's the architecture. Open the network tab in DevTools while you use any tool on this page and you'll see requests for fonts and the favicon, and nothing else.
