  • •JSON literal-preservation preserves exact formatting and key order
Weaknesses
  • •No novel techniques beyond privacy, commodity functions available elsewhere
  • •No tool chaining or advanced workflows like CyberChef offers
Target Audience

Post Description

I got tired of spammy data formatting tools, so I built my own. There's no backend, uploads, ads, analytics. Everything runs locally in the browser and works offline after first load. You can verify this using DevTools → Network tab.

I put in everything I could think of: formatter, validator, JWT decoder, Base64, hash, CSV/Excel/YAML/TOML converters, protobuf decoder, and a whole bunch more.

Feedback welcome on what's missing or what's broken.

Upload App Store Screenshots Directly from Figma to App Store Connect

It removes the boring middle step — pick frames in Figma, validate sizes, preview store pages and push straight to App Store Connect with smart ordering and multi-locale support. Not groundbreaking if you're already scripting with Fastlane, but the one-click Figma → App Store UX is genuinely useful for small teams and marketers who hate manual exports; I’d want clarity on API limits and how it handles complex localization pipelines before buying.

API-pilot – deterministic API key resolution with runtime validation

Deterministic fallback order (ENV → .env → vault) plus an opt-in validation mode and a strict CI-friendly option is a practical combo I wish I'd had in several projects. The doctor CLI that lists found keys and minimal provider probes (e.g., GET /v1/models for OpenAI) is a nice touch — useful for catching bad tokens before a pipeline runs. It’s not reinventing secret managers, but the zero-deps, stdlib-only approach and CI strictness make it an immediately usable tool for small teams.
