UploadThing

UploadThing is a managed file upload service for modern TypeScript apps that handles the storage, security and client UI in one drop-in SDK. We rate it 84/100 — it is the fastest way to add production-ready uploads to a Next.js app, and the only service that doesn't charge per request or per GB of bandwidth.

What is UploadThing?

UploadThing was built by Theo Browne (creator of the T3 stack) and the team at Ping Labs. The first commit landed on May 10, 2023, and the service was declared production-ready on June 22, 2023. The open-source SDK lives on GitHub at pingdotgg/uploadthing with over 5,100 stars and an MIT license, while the hosted backend (storage, signed URLs, dashboards) is the paid product.

Where competing options like S3, Cloudflare R2, Bunny.net or Uploadcare hand you a bucket and a billing dashboard, UploadThing hands you a typed FileRouter, a React component, and a single endpoint that handles auth, validation, presigned URLs, virus scanning and webhook callbacks. The pitch is simple: you should not have to write 600 lines of S3 boilerplate to let users upload an avatar.

Key Features of UploadThing

• Type-safe FileRouter: Define accepted file types, size limits and middleware in one TypeScript object — the React hooks and components are typed against it end-to-end, so a route change is a compile error on the client.
• Drop-in React components: <UploadButton /> and <UploadDropzone /> ship with sensible defaults, progress UI, retry handling and accessibility baked in — you can wire up uploads in under 50 lines of code.
• Framework coverage: First-class packages for Next.js (App Router and Pages), SolidStart, SvelteKit, Astro, Remix, Vue and Express. The core SDK is framework-agnostic.
• No bandwidth charges: Unlike S3, Cloudinary or Uploadcare, UploadThing does not bill for requests, egress or seats — only the GB you actually keep on disk.
• Resumable large-file uploads: Multi-part presigned URLs handle files up to 1 GB on paid plans, with automatic retry on flaky connections.
• Server-side validation & middleware: Run auth checks, rate limits or DB writes in your onUploadComplete callback — the file is held until your server signs off.

What Users Say About UploadThing

Sentiment on Reddit's r/nextjs and Theo's "Typesafe Cult" Discord is overwhelmingly positive on developer experience — the most-upvoted threads describe shipping a working upload flow in "under an hour" versus "a full afternoon" with raw S3. The recurring complaints are concrete: the middleware on Next.js must explicitly allow /api/uploadthing or callbacks fail silently, edge-runtime deployments break because an edge function cannot fetch itself in dev, and Vercel projects with deployment protection turned on cannot receive UploadThing's webhook unless you configure the x-vercel-protection-bypass header. None of these are dealbreakers, but every one of them has its own GitHub issue with hundreds of comments.

On Hacker News and Product Hunt, the recurring praise is for the pricing change: in February 2025 Ping Labs killed legacy tiers in favour of pure usage-based billing, and developers consistently describe it as "the only file-upload pricing that doesn't punish virality."

UploadThing Pricing

UploadThing's published pricing is unusually simple for a storage product:

Plan	Price	What's Included
Free	$0/month	2 GB storage, unlimited uploads & downloads, 7-day audit log
100GB App	$10/month	100 GB storage, 1 GB max file size, longer retention
Usage Based	$25/month	250 GB storage included, then $0.08 per additional GB — no charge for seats, requests or bandwidth

Who Should Use UploadThing?

Best for: Solo developers and small-to-mid product teams shipping Next.js, SolidStart or SvelteKit apps that need user-generated uploads (avatars, attachments, video clips, course material) without becoming AWS experts. Particularly strong for products that get unpredictable traffic spikes — the no-bandwidth-fee model is a real cost-control feature.

Not ideal for: Apps that need region-pinned data residency for compliance (HIPAA, GDPR data-locality rules), workflows that require server-side image transformations at the CDN edge (Cloudinary territory), or anyone who is already deeply invested in raw S3 + their own auth proxy.

Pros and Cons

Pros:

• Cleanest type-safe upload SDK on the market — provably faster to integrate than DIY S3 according to multiple Reddit and HN threads.
• No per-request, per-seat or per-GB bandwidth charges — pricing is predictable for viral content.
• Open-source MIT SDK on GitHub with 5,100+ stars — you can read every line of the client.
• Drop-in React, Solid, Svelte, Vue and Express components with first-class TypeScript inference.

Cons:

• Production gotchas around Next.js middleware, edge runtime and Vercel deployment protection are common — the docs help, but you will read GitHub issues.
• No built-in image transformations or video transcoding — you bring your own pipeline.
• The hosted backend is closed-source, so self-hosting is not on the table.
• Free tier (2 GB) is small compared to the legacy 10 GB tier some older articles still mention.

Alternatives to UploadThing

The closest comparables are Uploadcare (more expensive, but ships built-in image CDN transformations), Cloudinary (the heavyweight for media-heavy apps that need transcoding and adaptive video), and rolling your own on Cloudflare R2 or AWS S3 with presigned URLs (cheapest, most painful to wire up).

Verdict: Is UploadThing Worth It?

Yes, with one caveat. If you are building a TypeScript web app and you need users to upload files, UploadThing is the fastest path from zero to production and the pricing model genuinely outclasses every other hosted option. The caveat is that you should be prepared to read a few GitHub issues the first time you deploy — the Next.js middleware and edge-runtime gotchas are real. We rate it 84/100: outstanding ergonomics, fair pricing, with rough edges that show up at the integration boundary rather than in the core product.

Frequently Asked Questions

Is UploadThing free?

Yes. The free tier includes 2 GB of storage with unlimited uploads and downloads. Paid plans start at $10/month for the 100 GB App plan, or $25/month for usage-based billing with 250 GB included.

What frameworks does UploadThing support?

Next.js (App Router and Pages), React, SolidStart, SvelteKit, Astro, Remix, Vue and Express, plus a framework-agnostic core SDK for any other Node.js or Bun environment.

Is UploadThing open source?

The client SDKs and React/Solid/Svelte components are open source and MIT-licensed on GitHub. The hosted backend — storage, signed URL signing, dashboards — is closed-source SaaS.

How does UploadThing compare to S3 and Cloudflare R2?

UploadThing is built on top of object storage and trades raw cost for developer time. S3 and R2 are cheaper per GB but require you to wire up presigned URLs, auth, validation and a webhook pipeline yourself. UploadThing handles all of that and bills only on storage, not bandwidth.

Does UploadThing charge for bandwidth?

No. UploadThing does not charge for requests, downloads, bandwidth or team seats — only for the GB you keep on disk. This is the main pricing differentiator from Uploadcare, Cloudinary and DIY S3 setups.
