Best AI agent skill marketplaces in 2026

The best AI agent skill marketplace depends on what you need. Use skills.sh for install-led open-source discovery, SkillsMP for broad GitHub search, Anthropic's repository for first-party examples, Agensi for paid SKILL.md packages, and Capabase for free and paid specialist AI setup products. These are different kinds of destination, so one winner would be misleading.

This comparison was checked on September 15, 2026. It covers public evidence about source access, updates, review, and creator payments. It does not treat install counts, catalog size, or a scan badge as proof that a skill is good.

The five destinations are not the same kind of product

The open Agent Skills specification defines the common artifact: a directory with a required SKILL.md file and optional scripts, references, and assets. Distribution is outside that standard. One site may index public GitHub folders. Another may sell private archives with checkout and support.

• skills.sh is an open registry and install leaderboard for public repository skills. It suits fast discovery with a direct GitHub trail.
• SkillsMP is a broad GitHub index with public source previews and downloads. It suits searches across occupations, creators, and repositories.
• Anthropic skills is a first-party source collection with free access and mixed licenses. It suits learning from official examples.
• Agensi is a commercial SKILL.md marketplace with free, paid, and subscription listings. It suits buying or selling packaged skills.
• Capabase is a commercial marketplace for free and paid AI setup products. It suits buyers who need listing and delivery context.

That distinction should shape the choice. A public index is easier to inspect. A commercial marketplace can add payment, delivery, licensing, updates, and creator support. Neither removes the need to read the package.

skills.sh for install-led open-source discovery

skills.sh is the cleanest starting point when you want a public skill and a direct install command. Its listing pages show the repository owner, source link, SKILL.md preview, install count, first-seen date, and available security-audit results. The open skills CLI installs from the named repository.

The ranking comes from aggregated install telemetry. That makes it a popularity signal, not a quality score. skills.sh says it runs routine audits and also says it cannot guarantee the quality or security of every listing. Use the leaderboard to find candidates, then follow the repository link and inspect the actual files and commit history.

Versioning is repository-led. On the listing audited for this article, skills.sh showed when the skill first appeared but no separate package version. If controlled releases matter, check the source repository for tags, commits, and a changelog.

SkillsMP for broad GitHub search

SkillsMP describes itself as an open map of public SKILL.md files. You can search by task, creator, repository, category, occupation, or keyword. A listing can expose the source repository, last source activity, companion files, a read-only preview, an install command, and a ZIP of the files currently available to SkillsMP.

This is useful when the job is obscure and a popularity leaderboard keeps returning the same familiar repositories. It is also noisy by design. SkillsMP says its popular picks are not a live ranking, quality certificate, or safety review. The site brings you back to the source; it does not replace source review.

There is no commercial support promise attached to an indexed GitHub file. Check its license, maintainer activity, dependencies, and issue history yourself.

Anthropic's repository for first-party examples

The Anthropic skills repository is the best reference here for seeing how the company behind Claude structures its own examples. Each skill has a folder and SKILL.md. The repository also includes a template and Claude Code plugin installation paths.

It is not a neutral marketplace. The collection shows Anthropic's implementation and selected partner work. Many folders use Apache 2.0, while the document skills are source-available under different terms. Read the license in the package you plan to reuse.

Anthropic also labels the repository as demonstration and educational material. It warns that behavior in Claude may differ and tells users to test skills in their own environment. That is a useful standard for every source in this list.

Agensi for paid SKILL.md packages

Agensi is a commercial marketplace focused on zipped SKILL.md packages. Its public browse page separates free, paid, subscription, deal, and bundle listings. The creator page says paid source files stay hidden from public listing pages and that buyers receive versioned updates.

Agensi says each submission gets an eight-point automated scan, an AI safety and intent review, and a human check. Treat that as the marketplace's review description, not independent proof. A buyer still needs to check required tools, network calls, scripts, permissions, and support terms.

For creators, the current seller page states a 70% share of net revenue, paid through Stripe or USDC, with a 30% platform fee. Check the current terms before listing. The audited seller and browse pages displayed conflicting catalog totals, so this article does not repeat either number.

Capabase for specialist AI setup products

Capabase is a commercial marketplace for AI setup products. The current browse page exposes free and paid AI skill listings with a creator name, price, purchase count, rating state, and updated date. Capabase also supports other product formats in its product model, but the audited browse result currently contains AI skills only.

Archive products go through review. The Capabase terms define that review carefully: it may include automated and manual checks for provenance, suspicious tool use, secrets, malware indicators, and listing accuracy. It is not a guarantee that a product is safe or suitable for every environment.

Current terms state that creators receive an 85% gross share of the product price excluding taxes, before refunds, disputes, and other listed deductions. Buyers should choose Capabase when commercial delivery, creator identity, listing context, and support expectations matter. Buyers who want a fully public repository should use a source-first directory instead.

Choose the marketplace by what you need to verify

Start with the question the destination must answer.

• For public source and a quick install path, start with skills.sh.
• For broad discovery across GitHub, use SkillsMP.
• For first-party Claude examples, inspect Anthropic's repository.
• For paid SKILL.md packages and creator commerce, compare Agensi listings.
• For specialist AI setup products with commercial listing and delivery context, browse Capabase.

Then evaluate the individual skill. Our guide to choosing an AI skill covers scope, creator evidence, sample output, dependencies, permissions, support, updates, and license. The free versus paid comparison explains what a paid package should add beyond a public folder.

A marketplace can reduce search and transaction work. It cannot prove that a package fits your environment. Read SKILL.md, inspect every script, note external services and credentials, and test with low-risk inputs before using it on important work.

Common questions

What is the safest AI skill marketplace?

No public directory or marketplace can guarantee that every skill is safe. Prefer visible provenance, inspectable files where available, precise review wording, current update signals, and clear disclosure of scripts, network access, and permissions. A clean automated scan is useful evidence, but it is not a security guarantee.

Are paid AI skills better than free skills?

Price does not prove quality. Free skills work well for common methods and open-source tooling. A paid skill should justify its price with specialist judgment, stronger examples, documented limits, updates, support, or a commercial license. If the listing only paraphrases a generic prompt, keep your money.

Can the same skill work in Claude Code, Codex, and Cursor?

A standards-compliant folder can be portable, but the host still controls discovery paths, tools, permissions, and runtime behavior. Check the listing's compatibility claim, then test the skill in each agent you plan to use. Do not assume one successful run proves cross-agent support.

You can browse current AI skills on Capabase. Inspect the listing, package requirements, creator evidence, and review notes before buying or installing.
