About essentials.sh

Every site ships with the same small chores: a QR code for the launch post, favicons in six sizes, meta tags that unfurl properly on social, a robots.txt, a sitemap, an llms.txt, a social share image. None of them are hard — but each one usually means finding yet another ad-covered converter or opening a design tool for a 90-second task. essentials.sh is the checklist of those chores turned into instant tools, one predictable URL per task.

Principles

• Nothing leaves your browser. Images and text you put into a tool are processed locally — there is no upload endpoint, no storage, and nothing to leak.
• Free, no accounts. Open a tool, get your result. There is nothing to sign up for and no paid tier waiting behind the third click.
• Built for agents too. The same generators are exposed as a free REST API and MCP server, the site speaks markdown to crawlers, and discovery endpoints (llms.txt, OpenAPI, agent skills, DNS-AID) are first-class — being usable by AI agents is part of the product, not an afterthought.

The project is developed in the open at github.com/cashmash-io/essentials — the roadmap, issues, and every change are public. Found a bug or want a tool added? Get in touch.
