🤖 Robots Sitemap Validator

by JustHandled Labs

Free

Check your robots.txt and sitemap.xml for the mistakes that quietly block crawlers. Flags a site-wide Disallow: /, malformed directives, a missing Sitemap: line, sitemap XML that is not well-formed, <loc> URLs missing a scheme, mixed http and https, and sitemaps over the 50,000-URL or 50MB limits. Reads local files or pasted text and never touches the live site.

🩺 llms.txt Doctor

by JustHandled Labs

$9

Generate an llms.txt for your site and validate an existing one against the spec. The generator turns your sitemap.xml or docs folder into a clean, sectioned llms.txt with one-line descriptions. The validator flags a missing H1 title, a missing summary blockquote, malformed link entries, links with no description, relative URLs that should be absolute, and a referenced llms-full.txt that is not present.

📏 Handle Rules Linter

by JustHandled Labs

$9

Check a desired handle against every platform's username rules and find the form that works everywhere. Flags handles that break a platform's length limits, use a disallowed character (like a period on YouTube or TikTok), or start with a disallowed character, and recommends the safe consistent form (4 to 15 lowercase alphanumeric). Covers X, Instagram, TikTok, YouTube, Twitch, GitHub, and Bluesky. It checks the rules, not availability.

factur x france

by Nex AI

$9/mo

Generate and validate Factur-X/ZUGFeRD hybrid e-invoices compliant with the French EN16931 mandate.

🕵️ Confusable Handle Detector

by JustHandled Labs

$5

Flag the hidden and look-alike characters lurking in a handle or brand string. Catches zero-width characters, mixed-script look-alikes (a Cyrillic "а" passing as a Latin "a"), right-to-left and bidi override characters, unexpected non-ASCII, and stacked combining marks. These are the spoofing tricks and display bugs you cannot catch by reading.

📚 Reference Grounding Checker

by JustHandled Labs

$15

Before an agent acts on a plan, verify that the things it named actually exist. Checks each referenced file path, function or method, import or package, environment variable, and CLI command against your repo, and flags the ones that do not resolve. Catches the hallucinated function and the phantom package before the edit, not after the build breaks. Resolves Python and JavaScript/TypeScript.

🔳 QR Payload Auditor

by JustHandled Labs

$5

Audit the decoded text a QR code carries before you print it on something. Flags URLs that are not absolute, link shorteners that hide the real destination, unsafe schemes (javascript:, data:, file:), payloads too long to scan reliably, malformed Wi-Fi or contact payloads, and exposed credentials like a Wi-Fi password or a token sitting in a URL. It audits the decoded payload you paste; it does not read images.

Redis Cache Architect

by Arnstein Larsen

$8.99

A cache without an invalidation story isn't an optimization — it's a stale-data generator with good latency numbers

by Nex AI

$9

Scaffold legal entity formation, VAT validation, and compliance documentation for the Netherlands, Belgium, and Luxembourg.

Gutenberg Block Pattern Generator

by Arnstein Larsen

$8.99

Convert existing HTML sections or plain descriptions into production-ready Gutenberg block patterns that inherit your theme's design system — no hardcoded colors, no inline styles, no editor validation errors.

🩹 Customer Pain Extractor

by JustHandled Labs

$12

Pull the real pain points out of your customer feedback so you build what people actually want. Paste a dump of comments, reviews, forum threads, or support tickets and it extracts the complaints, wishes, churn signals, and pricing objections, clusters them into ranked themes, and shows the example quotes behind each one. The "pull ten pains, tag by theme" validation step founders skip, done in one pass.

API Contract Tester

by Arnstein Larsen

$5

Turns an OpenAPI/Swagger spec into an exhaustive, framework-ready test suite — happy-path, validation, contract-conformance, auth, and defensive security tests — with a coverage matrix mapping every endpoint, status code, and schema constraint to a test.
