Introducing Redenv - A Zero-Knowledge, End-to-End Encrypted Secret Manager Built for the Serverless Era

PRAS Samin — Tue, 25 Nov 2025 15:38:51 +0000

For months, I’ve been quietly building something I felt the JavaScript/TypeScript ecosystem desperately needed… a modern alternative to .env files that isn’t just another wrapper, but a complete rethink of how we manage application secrets.

Today, I’m excited to finally share it publicly.

Redenv - A Zero-Knowledge Secret Management System
A developer-first, fully end-to-end encrypted CLI + runtime client designed so teams can finally stop treating secrets as afterthoughts.

Why I Built This:
Every developer today faces the same pains:
• .env files get out of sync
• Secrets leak in logs, terminals, Git history
• Sharing secrets in teams becomes a mess
• Serverless platforms force the "rebuild to rotate" cycle

Rotating a single API key requires redeploying the entire application
This felt outdated. So I built Redenv around one belief:
Configuration should be dynamic, secure, and completely decoupled from deployment.

What Makes Redenv Different:
• Zero-Knowledge Architecture: All secrets are encrypted using AES-256-GCM with keys derived from PBKDF2-HMAC-SHA256 (310k iterations). Your Redis database never sees plaintext. Not even for a millisecond.
• Redis as a Universal Backend: Built exclusively on Upstash Redis for instant cold starts, global edge performance, serverless pricing, and connectivity from anywhere.

Redenv includes:
— CLI (@redenv/cli)
A polished, full-featured command-line tool with commands like add, edit, view, history, rollback, diff, clone, backup, restore, token create, and so on.

— Runtime Client (@redenv/client)
A lightweight, zero-knowledge client library with:
• In-memory stale-while-revalidate caching
• Instant startup
• Auto population of process.env
• Dynamic updates without redeploying
• Programmatic writes using service tokens

You can rotate an API key and your deployed applications will pick it up automatically, without any rebuild or redeployment. This is a game changer for serverless workflows.

Comparison:
There are many enterprise secret managers and vault systems out there, and they are great for large companies. The difference here is simple: Redenv is fully open-source, developer-first, extremely fast to set up, and gives you maximum control without locking you into a vendor ecosystem.

Final Thoughts:
I believe Redenv can simplify your workflow massively. It’s a fully documented, production-ready open-source project that I’m genuinely proud of.
If you're building:
• Serverless apps
• Edge functions
• SaaS products
• Multi-env systems
• Microservices
• Anything where secrets matter

Thinking of building a modern CLI for managing custom commands - would you use it?

PRAS Samin — Tue, 07 Oct 2025 05:13:58 +0000

Hey 👋
I’m experimenting with an idea for a new command-line tool to enable developers to build, organize and run their own custom commands in JavaScript - it’s like a modern version of hacking together bash scripts.

🧩 The Problem:
Shell scripting is ugly and non-portable (across MacOS, Linux, Windows).
You start hacking up. sh scripts.
Working with personal scripts (so you make them executable, list them, sync your changes) is awkward.

⚡ The Idea:
A CLI that serves as your personal command manager, you can:
Scripting in JavaScript (with a little helper API).
Save them to a place — immediately usable elsewhere as subcommands, e.g., mycli deploy or mycli clean.
Manage them as easily: mycli add, mycli list, mycli remove.

(Later) sync/backup them cloud or even per-project automation through devDependencies.

It's like if npm, bash and VS Code snippets had a baby 😅

🧭 Tech Vision:

Built as a Node. js CLI (via NPM).
Load your JS scripts dynamically at runtime using libraries such as Commander and Yargs.
Each one is run right inside the cli’s fancy, stand-alone JS runtime (fast and also portable).

I’m curious:
👉 Will you would use something like as a replacement of little bash scripts or task runners?

I would like to receive some feedback prior to actively developing it.

I made an open-source, ad-free content downloader that simply works

I made an open-source, ad-free content downloader that simply works

Every time I tried downloading a video online, I ended up on some shady website full of popups, fake buttons, and trackers. All I wanted was a clean, safe way to download content for offline viewing, education, and inspiration - without ads or hidden scripts.

So I created Fetchy an open source ad free content downloader which is fast, privacy-friendly and operates directly from your browser.

Why I built it

I grew tired of fake “Download” links, annoying redirect loops and websites that use your bandwidth to display ads.

Fetchy was created on a premise that transparent and user respectful utilities should be open demoninator.

What's unique about it

🚫 No ads or tracking - first and foremost, privacy.
🌍 Open source - inspect, fork, or contribute to it on GitHub.
⚡ Just works - clean interface, no extensions or sign up needed.
🧱 Modern solutions - lightweight front-end and moderate back-end that doesn't bag down on popular sites.

🌐 Try it

If you find it useful, or just plain interesting, then a ⭐ on GitHub means the world.

And if you have thoughts on making it better, open an issue or get in the discussion - I’d love to collaborate with the community.
