Documentation · Version 1.0

Everything you need to use and understand Ergastírio.

A complete guide to the workshop, its tools, privacy model, architecture, design language, and development workflow.

01 · Introduction

A workshop, not a product suite.

Ergastírio (Εργαστήριο) means workshop. It is a collection of focused utilities that solve one job well, share one visual system, and avoid unnecessary accounts, subscriptions, and data collection.

02 · Getting started

Use the tools directly. No setup required.

Open a tool from the hub or navigate directly to its route. Every tool works without an account and remembers lightweight preferences in your browser.

01

Choose a tool

Start from the hub or use a direct route.

02

Do the work

Enter a URL, generate a QR, or test typography.

03

Export or act

Download the result or apply the recommended fixes.

03 · Argus

Website intelligence with actionable fixes.

Argus analyzes a public webpage, produces an overall score, groups findings by category and priority, then explains why each issue matters and how to fix it.

01

Technical SEO

Titles, descriptions, canonical URLs, headings, robots, sitemap signals, and social metadata.

02

Performance

Markup heuristics for render blocking, image optimization, Core Web Vitals risks, and delivery quality.

03

Accessibility

Alt text, form labels, semantic structure, heading order, ARIA usage, and interaction concerns.

04

Security

HTTPS and response header checks including CSP, HSTS, frame protection, MIME protection, and referrer policy.

05

AI readiness

Schema, semantic structure, summaries, question headings, lists, tables, and entity clarity.

How to use
  1. 1. Enter a complete public URL.
  2. 2. Wait while the server proxy fetches the page.
  3. 3. Review the score and category breakdown.
  4. 4. Open an issue to see its explanation and fix.
  5. 5. Re-analyze after applying changes.
Important limits
  • • The page must be publicly reachable.
  • • Private IPs and localhost are blocked for security.
  • • Some hosts may block automated requests.
  • • Results are guidance, not a replacement for a full lab audit.
04 · Kýklos

Permanent QR codes generated in your browser.

Kýklos creates QR codes locally. The code itself has no expiry because it directly stores the provided content rather than depending on a redirect service.

Size and margin controls
Error correction
PNG/SVG export
Local generation
No expiry
Zero tracking
Recommended workflow

Enter the destination, choose contrast-safe colors, select the required size and error-correction level, test the preview with a phone, then export PNG for general use or SVG for print and scalable artwork.

05 · Grámma

A practical typography workspace.

Grámma helps you discover, test, compare, pair, favorite, and export type specimens without leaving the tool.

Live specimen text
Font search and filters
Favorites
Font pairing
Side-by-side comparison
PNG/PDF export
Theme persistence
Responsive preview controls
Preview

Write your own specimen text and apply it to the selected font. Adjust preview settings to judge real content rather than a fixed sample.

Compare & export

Compare several fonts side by side, explore suggested pairings, and export the final specimen as PNG or PDF.

06 · Privacy & data

Local by default, transparent when a server is required.

The tools avoid accounts, analytics, and behavioral tracking. Browser storage is only used to preserve preferences and useful local history.

07 · Architecture

A focused Next.js application.

The project uses the App Router, TypeScript, Tailwind CSS, Motion, and Lucide icons. Each tool has a direct route and keeps its domain logic close to its UI.

Development

npm install
npm run dev

Validation

npm run lint
npm run build
08 · Design system

Quiet, precise, and intentionally restrained.

Every page shares the same visual foundation: near-black surfaces, translucent panels, compact controls, mono-led typography, restrained accents, and purposeful motion.

Color tokens

Backgroundvar(--background)
Panelvar(--panel-solid)
Controlvar(--control)
Accentvar(--accent)

Interaction rules

  • • Controls remain compact and clearly clickable.
  • • Motion explains state, never distracts.
  • • Focus and hover states are always visible.
  • • Dark and light themes share the same hierarchy.
09 · Troubleshooting

Common issues and what they mean.

Most issues are caused by unreachable websites, browser extensions, stale development bundles, or invalid input.

Argus cannot reach a website

Confirm the URL is public and uses HTTP or HTTPS. Some providers block automated server requests; try another public page to verify.

Hydration warning in development

Browser extensions can modify body attributes before React loads. Test in a private window with extensions disabled before changing application code.

A route returns 404

Use the documented routes exactly. Paths such as /workspace/home are not application routes.

Theme looks incorrect

Clear the ergastirio-theme value in localStorage or use the theme toggle to reset the preference.

Export is blocked

Allow downloads for the site and make sure the browser supports canvas and Blob-based downloads.

10 · Contributing

Keep changes focused and consistent.

Contributions should solve a clear problem, preserve privacy, reuse the existing visual language, and include validation before submission.

Before opening a PR
  • 1. Keep the scope small and intentional.
  • 2. Match existing component patterns.
  • 3. Avoid unnecessary dependencies.
  • 4. Run lint and a production build.
  • 5. Explain behavior changes clearly.
Project links

That is the complete workshop.

Use the navigation to revisit a section, open a tool to begin working, or view the repository to inspect the implementation.
