Verification Standards (NLW-STD-001)

1. Abstract & Scope

The proliferation of mandatory authentication walls, opaque telemetry, and data extraction has degraded the fundamental accessibility of web software. Simple utilities—such as image compressors, SVG editors, regex analyzers, and markdown converters—frequently demand personal identifiers (email addresses, phone numbers, social credentials) as an artificial fee for entry.

This document establishes NLW-STD-001, the definitive technical standard for the No-Login Web. It defines the architectural requirements a web service must fulfill to receive official certification from NoLoginTools.org, the mechanical rules governing automated uptime and compliance crawling, and the semantic specifications for embeddable trust badges.

Terminology (RFC 2119): The key words "MUST", "MUST NOT", "REQUIRED", "SHOULD", and "MAY" in this document are to be interpreted as described in BCP 14, RFC 2119.

2. The Three Core Principles (Normative)

To qualify for No-Login Web certification, a tool MUST satisfy all three foundational principles across its core functional workflow:

Immediate Functional Utility

The primary stated utility of the service MUST be usable immediately upon page load. The service MUST NOT block the primary action behind registration, login, phone verification, credit card input, or email confirmation modals.

Zero Arbitrary Data Retention

User input processed by the tool SHOULD remain client-side (leveraging WebAssembly, Web Workers, Web Crypto, Canvas, or LocalStorage). If transient server processing is computationally mandatory, the system MUST NOT persist user payload data beyond the immediate request-response lifecycle, and MUST NOT correlate payloads with persistent tracking fingerprints.

Absence of Deceptive Coercion

The service MUST NOT employ "bait-and-switch" friction patterns—such as permitting unrestricted file editing or generation, but gating the subsequent export, download, or copy button behind a mandatory sign-up wall.

3. The 3-Tier Trust & Verification Hierarchy

Certification is not a one-time binary badge, but a continuous trust lifecycle spanning three distinct operational tiers:

Tier Level	Designation	Audit Mechanism	Ecosystem Privileges
Level 1	Directory Listed	Initial human UX audit + 7-dimension classification.	Permanent listing in directory, multi-language cataloging.
Level 2	Certified by NoLoginTools.org	Continuous 6-hour health checks, latency & SSL tracking.	Unique Digital Trust Certificate at `/badge/[slug]`.
Level 3	Badge Verified Active	Dual-surface automated crawler verifies badge on site or GitHub.	Green shield icon (🛡️), +10 algorithmic ranking boost, priority indexing.

Moving from Level 2 to Level 3 requires the tool author to embed the official badge into their production web page or public GitHub repository README.md, establishing a verifiable bi-directional link of authority.

4. Badge Technical Specification (v1.2)

Official badges issued by NoLoginTools.org are vector SVGs optimized for sub-millisecond rendering, zero tracking pixels, and universal screen readability.

4.1 Visual Styles & Metrics

The badge engine provides 13 officially certified variations categorized into four groups:

Standard (4): flat (118×20), flat-square (118×20), plastic (116×18), for-the-badge (191×28). Left plate slate (#555), right plate green (#4c1).
Social (1): social (142×20). Pill contour with light left plate (#fafafa) and green badge plate.
Dark (4): flat-dark, flat-square-dark, plastic-dark, for-the-badge-dark. Left plate dark (#2d2d2d), right plate vibrant (#3fb950).
Accent Color (3): flat-blue (#07c), flat-purple (#8957e5), flat-orange (#fe7d37).
Original Legacy (1): High-contrast white background rectangular badge (/badge.svg).

4.2 Required Shield Iconography & Semantics

All modern variants (v1.1+) MUST incorporate the official vector shield insignia:

• Shield Vector: 12×12 viewBox base scale with embedded checkmark stroke.

• Accessibility Tag: aria-label="Verified by NoLoginTools.org"

• Native Tooltip: <title>Verified by NoLoginTools.org</title>

4.3 Canonical Embedding Protocol

Maintainers MUST link the badge directly to their issued certificate URL to enable crawler verification:

Markdown Standard

[![Verified by NoLoginTools.org](https://nologin.tools/badges/flat.svg)](https://nologin.tools/badge/YOUR-TOOL-SLUG)

HTML Standard

<a href="https://nologin.tools/badge/YOUR-TOOL-SLUG" target="_blank" rel="noopener">
  <img src="https://nologin.tools/badges/flat.svg" alt="Verified by NoLoginTools.org" title="Verified by NoLoginTools.org" />
</a>

5. Automated Verification Engine & Crawler Protocol

Compliance is enforced continuously through automated inspection daemons executed via edge workers:

Dual-Surface Discovery

The crawler executes a dual-surface inspection pipeline. First, it analyzes the HTML DOM of the tool's homepage and footer. Second, if a public repository URL is registered, it requests the raw markdown payload of README.md directly from GitHub's raw CDN.

User-Agent Transparency

Crawler User-Agent: NoLoginTools-BadgeChecker/1.0
Health Auditor User-Agent: NoLoginTools-HealthChecker/1.0

All automated requests provide distinct, transparent User-Agents to prevent false bot triggers while adhering to standard web robotics protocols.

Fault-Tolerant Health Intelligence

The health monitoring engine adopts an intelligent reachability model: HTTP responses including 403 (Cloudflare WAF challenges) or 429 (rate limits) confirm server existence and do not register as outages. Only total connection failure, DNS timeouts, or 404/410 not-found errors mark an unreachability event. A sliding window of 5 checks with fast-recovery safeguards prevents temporary network blips from penalizing verified maintainers.

6. Anti-Gaming, Cloaking & Revocation Protocol

To maintain absolute trust integrity, the following practices are strictly prohibited:

User-Agent Cloaking: Serving an account-free interface to NoLoginTools-HealthChecker while serving login walls to real human visitors.
Bait-and-Switch Gating: Updating a previously verified service to introduce compulsory signup steps for essential functionality.
Badge Spoofing: Embedding badge SVGs linking to fraudulent certificate targets, competitor pages, or spoofed URLs.
Tracker Injection: Embedding unauthorized third-party telemetry within badge delivery containers.

Revocation Policy: Tools detected in violation of these rules will immediately have their certification revoked. Their certificate status will update to REVOKED or REJECTED, all directory boosts will be stripped, and the infraction will be permanently recorded in the public git commit audit trail.

7. Public Audit Trail & Archival Footprint

Trust requires radical transparency. All evaluation states and health records maintained by NoLoginTools.org are permanently preserved across redundant public archives:

Open Data Feed: The complete directory database is synced every 6 hours to the public open-source repository awesome-nologin-tools under the CC0 1.0 Universal license.
Wayback Machine Integration: Every newly certified tool submission triggers an automated snapshot request to the Internet Archive Wayback Machine.
Transparent Certificate URIs: Every certified tool possesses an immutable certificate endpoint (https://nologin.tools/badge/[slug]) displaying verification timestamps, uptime records, and audit history.
