What we benchmark
Every comparison hits the same five questions: monthly price, free-tier shape, max file size, free-tier credit-card requirement, and what you actually get for the money. Numbers come from the vendor's pricing page on the day we published — we re-check quarterly.
/alternatives/<vendor>. In the meantime, the existing comparisons live under our blog: Filestack, Bytescale, uploadthing, file.io, transfer.sh, imgbb, Cloudinary.
The framing
Most file-upload APIs are priced for sales decks, not for usage. FilePost is the opposite — flat $9/mo for 5,000 uploads, $29/mo for 25,000. No annual contracts. No "contact us" tier. The competitors we benchmark below all do something well; we tell you what.
When a competitor wins
If you need image transformations server-side, Uploadcare and Cloudinary do it better. If you need OCR/AI features baked in, Filestack. If you need a temporary one-off file share, transfer.sh. If you're already in the Vercel ecosystem, uploadthing. We say so on the page.
