Stow vs Vercel Blob

At a glance

Topic	Stow	Vercel Blob
What it is	A hosted library for the files and data your apps and AI agents use, with one HTTP API.	Object storage from Vercel, cached by Vercel’s CDN, in one of 19 regions.
Getting started	Sign up, add an app, and use its key. No buckets or access policies to set up.	Create a store and connect it to a Vercel project; connected projects sign in automatically, with no long-lived secrets.
Uploading	One request with a file or with text as JSON. The file type is detected from its contents. Up to 25 MB per file.	SDKs for JavaScript and Python and a CLI, uploads straight from the browser with client tokens, and multipart for large files.
Finding files	Built-in search by tags (including key:value tags), text, folder and file type.	List by path prefix, and read one file’s details. No tag or text search is documented; the docs suggest organizing by prefix.
Private files	Upload with visibility set to private: the file gets no link at all, and only your keys can read it.	Chosen per store when it’s created. Private stores serve files through your functions with a token; signed URLs last up to 7 days.
Public links	Every public file gets a permanent link, cached for up to a year.	In a public store, anyone who has a file’s URL can open it.
Automatic analysis	On Pro and Scale: audio transcripts, summaries and tags, written automatically.	None in Blob.
AI agents	A plain HTTPS API any agent can call. A Stow MCP server is in early access.	Vercel’s official MCP server can create and look up Blob stores, but not upload, list or read files.
