Why this hub
Evaluate the catalog before you commit
Start with the use case, then move into the product that actually fits the job.
Built around real work
Spreadsheet cleanup, payload transforms, manifests, steganalysis — tasks developers actually do, not demo scenarios.
Discovery without noise
The hub tells you what exists, who it's for, and when to use it. Then it gets out of your way.
The catalog
Products in the arena
Each tool has its own public surface, product focus, and place in the broader catalog.
How it works
Three steps, zero friction
Find your fit
Start from the use case, not a product name. The catalog explains what each tool does and when to reach for it.
Open the subdomain
Each tool lives on its own subdomain with its own interface. One click from the catalog and you're in — no account needed.
Work locally
Browser-only tools process your data on your device. Close the tab and nothing is left behind.
Solutions
Positioned around real use cases
The hub is organized around workflows instead of forcing every tool into one generic dashboard.
Solo Developers
Fast utilities for debugging, data cleanup, privacy-safe experiments, and one-off tasks.
Replace throwaway local scripts with purpose-built browser tools.Small Product Teams
Shared workflows for support, QA, and operations without sending internal files to random SaaS tools.
Keep routine operational tooling consistent across the team.Security-Minded Users
Privacy-first tools where local execution matters and network dependency should be minimized.
Prefer local-first processing when the file itself is sensitive.Structure
One domain family, many products
The root site handles discovery and navigation. The tools themselves stay decoupled on subdomains — each with its own interface and release cycle.
