How I built a 100% client-side suite of 109+ web tools with $0 server costs
Hey Indie Hackers!
I just launched the product page for OmniDeck (https://omnideck.cc), and I wanted to share a bit about why and how I built it.
The Problem
Like many developers and makers, I use quick web utilities daily—formatting JSON, decoding JWTs, checking regex, or inspecting network data. But most popular online tools have become terribly bloated, covered in aggressive ads, or worse: they process your sensitive payloads on remote servers with unknown logging policies.
The Solution
I built OmniDeck as a zero-friction, privacy-first utility hub. Every tool runs 100% locally in your browser's memory—no backend database, no user tracking, no signups, and no intrusive pop-ups or paywalls blocking your workflow.
The Architecture
Frontend: Pure Vanilla JS, HTML, and a single global CSS file.
Edge Layer: A single Cloudflare Worker handling routing and using
HTMLRewriterto dynamically inject localized Open Graph tags, canonical URLs, and structured JSON-LD schemas (WebApplication&FAQPage) on the fly.Performance: Instant global load times with practically $0/month in infrastructure costs.
It currently features 109+ tools across categories like Dev, Crypto, Network, Image, PDF, and AI (using a Bring-Your-Own-Key model).
I’d love to get feedback from fellow makers here. What daily utilities do you find missing in your workflow, or what would you improve?
The privacy-first angle makes sense for utility tools where users often paste sensitive data without thinking twice.
The interesting challenge is discoverability — with 100+ tools, the hard part may be helping users find the one they need at the exact moment they have the problem.
