🚀 Launch Readiness Checklist Generator

by JustHandled Labs

$9

Generate a personalized before-you-ship checklist for your app, with the things you already have checked off. Pick your app type (web app, SaaS, store, or content) and it builds a tailored list covering security, legal basics (privacy policy, terms, cookie consent), social preview, payments and refunds, accessibility, analytics, and backups, then scans your repo and pre-checks what is already there. Every item says why it matters in plain English.

Developers waste time re-explaining their project to AI agents every session.

Accessibility Scanner

$7

🧪 Test Quality Auditor

by JustHandled Labs

$15

Find the unit tests that pass without testing anything. Flags tests with no assertions, trivial existence-only checks (toBeDefined, assertIsNotNone), tests that assert the exact value they just mocked, snapshot-only tests, tautological assertions (expect(true).toBe(true)), empty placeholders, and over-mocked tests with more setup than assertions. Works on Jest/Vitest and pytest/unittest.

✅ AI Code Verification Gate

by JustHandled Labs

$19

One-line summary description Stop your agent from claiming "done" before it's proven. A verification gate that classifies each change by risk (payment, auth, database, user-facing), picks the tests that actually cover it, demands evidence, maps regression risk, and outputs an honest pass/fail report. Turns "looks good to me" into "here's what I ran, and here's what's still unverified."
