As answered by people managing DUMMY DATABASE and SkillHQ.dev.
DUMMY DATABASE's answer
A free, all-in-one data generation platform that builds everything from simple tables to full relational databases with advanced controls, unique event sequences, ERD visualization, built-in SQL querying, and multiple export formats — no limits, no paywalls.
SkillHQ.dev's answer:
SkillHQ is the only paid marketplace for AI agent skills. Every competitor — AgentSkill.sh, Skills.sh, SkillsMP, ClawHub — is a free directory with no quality gate. Anyone can publish anything. SkillHQ validates every skill before listing (structure, content, and security checks), protects creators with invisible fingerprinting and SimHash piracy detection, and lets buyers install with a single CLI command. No other platform combines quality validation, one-command install, anti-piracy, and built-in creator monetization.
DUMMY DATABASE's answer
Unlike other data generators, DUMMY DATABASE gives you full relational database creation, unique event simulations, advanced control over every field, built-in SQL querying, and generous free limits — so you can go from idea to test-ready data without restrictions, subscriptions, or hidden fees
SkillHQ.dev's answer:
If you're buying skills: Free directories list 100,000+ skills with zero validation. That sounds like a lot until you spend three hours finding one that actually works. SkillHQ skills pass automated checks before listing — you're paying for the guarantee that what you install is production-ready. Run "skillhq install name" and it drops directly into your project. No manual copying, no debugging someone else's broken prompt.
If you're selling skills: There's no other platform where you can monetize AI skills with built-in payments. ClawHub creators reportedly earn $600–$20,000/month selling premium versions off-platform through Gumroad — proving the demand exists. SkillHQ closes that loop natively: 85% revenue share, zero listing fees, zero monthly minimums, Stripe Connect payouts to 45+ countries, and anti-piracy protection on every download.
DUMMY DATABASE's answer
SkillHQ.dev's answer:
Developers and small dev teams building with AI agents — specifically Claude Code and Custom GPTs. These are practitioners, not researchers. They want tools that work now, not experiments. On the buyer side, they're tired of filtering through unvalidated GitHub repos and free directories to find skills that actually do what they claim. On the seller side, they've built effective AI skills and want a real revenue path beyond open-source and GitHub stars. Both sides are technical, self-serve, and allergic to unnecessary friction.
DUMMY DATABASE's answer
Began as a project for myself to be able to have custom datasets for testing purpose I've decided that it could be useful for wider audience and finalized it as a full-stack web project
SkillHQ.dev's answer:
SkillHQ was born from a simple frustration: the AI skills ecosystem had no quality standard and no economics. Thousands of developers were building powerful Claude Code skills and Custom GPT configurations, then sharing them for free on GitHub with no feedback loop — no validation, no versioning, no way to know if what you found would actually work. Meanwhile, the best skill creators had no way to earn from their work.
We built SkillHQ to fix both sides. Think of it as npm for AI skills — a marketplace where every package is validated before listing, installable with one command, and worth paying for. Creators get 85% of every sale with zero upfront costs. Buyers get skills they can trust. The model is simple: when creators can earn, they build better skills. When buyers can trust what they install, they buy more. That flywheel is what makes a marketplace work.
