Upstash Blob adds 1 TB of monthly free egress to pay-as-you-go plan

Upstash Blob now includes 1 TB of egress each month on its pay-as-you-go plan, with charges for bandwidth applying after that limit. Egress is data that leaves a storage bucket, such as files users download. Upstash notes that a single upload can lead to many downloads, so bandwidth use can grow as an app gets more traffic even if its stored data remains small. The company says apps serving less than a terabyte monthly get their bandwidth at no cost under the allowance.

After the first terabyte, egress costs $0.02 per GB. Storage costs $0.02 per GB per month and is calculated using the bucket’s monthly average. Reads are priced at $0.30 per million, while uploads, copies and lists cost $4.50 per million. Upload bandwidth and deletes are free. These charges are separate from the egress allowance, so builders still need to account for storage and operation costs when estimating a bill.

The existing free plan is unchanged, with 1 GB of storage and 10 GB of monthly egress, and signup does not require a credit card. For pay-as-you-go customers, the egress rate is the same whether files are delivered from a CDN cache or from the origin. Public files use Cloudflare’s CDN without additional CDN fees, according to Upstash. Its comparison lists AWS S3 with 100 GB of monthly free egress shared across AWS services, followed by a $0.09-per-GB rate.

Upstash’s example considers an app serving 1,000 GB of files in one month: it says the bandwidth costs $0 on Blob. In the same example, S3 charges $81 for the 900 GB beyond its free tier. Upstash also describes Blob as offering browser uploads and a CDN through one typed SDK. It shares an account and bill with Upstash Redis, QStash and Workflow, and the company gives an example in which an upload callback starts a Workflow job to make thumbnails or index a document. Buckets are S3-compatible, so existing AWS SDK code works with them, according to Upstash.
