a fast and straightforward NoSQL cloud database service. With restdb.io you get schema, relations, automatic REST API (with MongoDB-like queries), and an efficient multi-user admin UI for working with data.
filess.io is a platform where you can create two databases with up to 10 MB per database of the following DBMS for free: MySQL, MariaDB, MongoDB, and PostgreSQL.
Multi-model cloud database — The 'Start' plan offers 1GB of storage free, forever, and a free compute instance with 0.25 vCPU and 1 GB memory ($0.000/hr). Further instances are available from $0.021/hr.
An agent can create a MongoDB Atlas M0 cluster via the API without an account. A person must sign in to claim the cluster, which then becomes a standard Free cluster with no expiration. Unclaimed clusters pause after 2 days and delete after 7. (From mongodb.com/docs/atlas/tutorial/create-ephemeral-cluster, read 2026-10-22.)
The Flex tier has a monthly base price of $8.00, which includes 5GB storage, 100 operations per second and unlimited data transfer. More operations per second cost extra by tier, and Flex clusters are capped at $30 per month. (From mongodb.com/docs/atlas/billing/atlas-flex-costs, read 2026-10-29.)
Upgrading a Free cluster asks for payment information and starts billing. Changing from a Free cluster to a Flex cluster requires downtime. (From mongodb.com/docs/atlas/scale-cluster, read 2026-10-29.)
