VERDICT

Should I use Antfu?

Anthony Fu @ antfu.me - antfu.me

Depends. This is not a product — it is a developer's personal site, and the valuable pieces are free open-source tools (ESLint config, AI agent skills) best suited to Vue/TypeScript developers. If you are shopping for supported, purchasable software with a vendor behind it, stop here; there is nothing to buy.

Confidence

Medium. Based on ~30 public sources. Note: antfu.me is a personal website of an open-source maintainer, not a commercial product, so pricing, vendor, and support dimensions are inherently thin.

Gotchas - check before you buy

Lock-in risk: adopting 2,291 opinionated rules is easy; unwinding them later is a large refactor.

CVE-2023-2972 hit @antfu/utils' set() function — pin an updated version if you depend on it.

Everything is free; 'payment' is donations via OpenCollective — no invoices, contracts, or support guarantees.

Agent-skills ecosystem is young; one user admitted not fully testing how well the skills work.
