SkillHQ is the first paid marketplace for AI agent skills. Developers buy production-ready Claude Code SKILL.md packages and Custom GPT configurations, then install them with a single CLI command. Skill creators publish their work and keep 85% of every sale.

The problem

The AI tooling ecosystem is fragmented. Developers spend hours searching GitHub for prompts and configurations that may or may not work. Free directories like AgentSkill.sh and Skills.sh list 100,000+ skills with zero quality gates โ€” anyone can publish anything. There's no reliable, curated source for production-ready AI skills, and no way for creators to earn from the skills they build.

Key features

  • One-command CLI install: skillhq install drops the skill directly into your ~/.claude/skills/ folder. Native Claude Code workflow, no workarounds.
  • Automated quality validation: Every listed skill passes structure, content, and security checks before buyers see it. No broken skills, no malicious payloads.
  • Anti-piracy protection: Every download is fingerprinted with invisible watermarks. SimHash paraphrase detection catches copies โ€” even rewritten ones. Full DMCA takedown process included.
  • 85% seller revenue share: The most generous split in the AI tools space. Zero listing fees, zero monthly subscriptions. Stripe Connect handles payouts to 45+ countries.
  • Auto-refund policy: If a buyer never downloads the skill file, they get an automatic refund. Sellers only earn when buyers actually use the skill.

Business model

Transaction-based. SkillHQ takes a 15% commission per sale. No subscription fees for buyers or sellers. Skills are priced between โ‚ฌ2 and โ‚ฌ50. Stripe Connect handles all payment processing and seller payouts.

Possible disadvantages of CodeSandbox

  • Performance Issues
    Some users experience lag and slower performance, particularly with larger projects, compared to local development environments.
  • Limited Customization
    While convenient, the pre-configured environments might limit advanced customization options available in local IDEs.
  • Dependency on Internet
    As an online platform, a stable internet connection is required to use CodeSandbox effectively, which could be a limitation in areas with poor connectivity.
  • Free Tier Limitations
    The free version comes with certain restrictions on resources and functionality, which might not be sufficient for larger or more complex projects.
  • Security Concerns
    Storing code in an online platform can raise security concerns, especially for sensitive or proprietary projects.
  • Learning Curve
    Despite its ease of use, developers new to online IDEs might face a learning curve in adapting from traditional, local development environments.

SkillHQ.dev features and specs

  • Skill-focused approach
    SkillHQ.dev appears to center its platform around specific skill development, which can help users focus on targeted learning outcomes rather than broad, unfocused education.
  • Developer-oriented branding
    The .dev domain and naming convention suggest a platform specifically tailored to developers and technical professionals, which could mean more relevant content for this audience.
  • Potential for structured learning paths
    Platforms with this naming convention often offer structured curricula or learning tracks that guide users through skill acquisition in an organized manner.
  • Niche market targeting
    By focusing on specific skills rather than being a general-purpose platform, SkillHQ.dev may offer deeper, more specialized content in its area of focus.
  • Modern platform positioning
    The branding suggests a modern, up-to-date approach to skill development, potentially incorporating current industry trends and technologies.

Analysis of SkillHQ.dev

Overall verdict

  • SkillHQ.dev appears to be a niche or emerging platform, and without verified, up-to-date information on its features, user base, or track record, it's not possible to confidently confirm its quality. Prospective users should independently verify its offerings, pricing, and reviews before committing.

Why this product is good

  • Specific, verifiable details about SkillHQ.dev's services, pricing, and user feedback are not readily confirmed.
  • As a dev-focused domain name, it likely targets developers or tech professionals seeking skill assessment or learning tools, but core functionality claims should be validated.
  • Lack of widespread reviews or established reputation makes it hard to assess reliability compared to more established competitors.
  • Users should check for transparency in terms of service, data privacy practices, and customer support responsiveness before relying on the platform.

Recommended for

  • Developers or tech professionals curious about niche skill-tracking or assessment tools willing to test a newer platform
  • Early adopters comfortable trying out less-established services
  • Users who conduct their own due diligence (reading recent reviews, checking company registration, testing free tiers) before committing time or money

Questions & Answers

As answered by people managing CodeSandbox and SkillHQ.dev.

What makes your product unique?

SkillHQ.dev's answer:

SkillHQ is the only paid marketplace for AI agent skills. Every competitor โ€” AgentSkill.sh, Skills.sh, SkillsMP, ClawHub โ€” 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.

Why should a person choose your product over its competitors?

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 โ€” 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 $600โ€“$20,000/month selling premium versions off-platform through Gumroad โ€” 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.

How would you describe the primary audience of your product?

SkillHQ.dev's answer:

Developers and small dev teams building with AI agents โ€” 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.

What's the story behind your product?

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 โ€” 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 โ€” 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.
