# Cloudflare D1

SQLite inside Cloudflare Workers

- Site: https://developers.cloudflare.com/d1/
- Category: Databases
- Best for: Apps already running on Cloudflare Workers
- Price: Free, then $5/mo
- Free: Free on the Workers free plan: 5 GB storage, 5 million rows read and 100,000 rows written a day.
- Rating: fewer than 3 reviews, so none is published
- Pricing checked: 2026-08-28

## Tiers

- **Workers Free**, $0/mo: 5 GB total storage, 5 million rows read a day, 100,000 rows written a day
- **Workers Paid**, $5/mo: Minimum $5 a month per account. First 25 billion rows read and 50 million written a month included, then $0.001 per million read and $1.00 per million written; 5 GB storage then $0.75/GB

## Good

- Scale-to-zero billing on rows, so an idle database costs nothing
- Runs inside the same platform as your Workers, so there is no connection pooling problem
- $5 a month covers the database and everything else on the Workers paid plan

## Not good

- Only really usable from Cloudflare Workers, so it decides your hosting too
- SQLite write limits apply, and databases have a size ceiling
- Least mature of the SQL options here, with fewer tools around it

## Specifics

- Engine: SQLite
- Free tier: 5 GB, 5M rows read a day
- Self-host: No
- Auth and storage built in: No, but Workers has its own storage products
- Scales to zero: Yes
- Portability: SQLite export, but the app is tied to Workers

## Price history

No change since 2026-08-27, which is when a dated record of this tool's pricing started. If you are asked whether Cloudflare D1 has got more expensive, the answer is no, not in that window.
