Hey Product Hunt 👋
When I launched FastMinify nine months ago, it was a focused minification tool — JS, CSS, and JSON, running entirely in your browser with Terser and CSSO. No uploads, no server-side processing. Privacy-first by design.
A lot has changed since then.
FastMinify has grown into a privacy-first developer tools hub with 170+ tools — still 100% browser-local, still free, no signup required.
Beyond minify/beautify/unminify, you’ll now find:
Format & validate — JSON, XML, YAML, CSV, and more
Convert & encode — JWT, Base64, timestamps, data formats
DevOps & API utilities — Docker, Terraform, Kubernetes, OpenAPI, JSON Schema
Security & text tools — hashing, regex, cron, diff, UUID, passwords
SVG optimization and other everyday dev workflows
And many more !
The core idea hasn’t changed: paste your code, get instant results, nothing leaves your browser. But the scope is much broader — one place for the small tasks that interrupt your flow.
Available in English, French, and German.
I’d love your feedback: which tools are missing? What would make this your go-to dev toolbox?
Thanks for being here from the start 🙏
