What KVdb.io is
KVdb.io is a key-value database and web API for serverless applications, prototypes, metrics, and other uses. Its REST API stores arbitrary key-value data and can read, delete, and list keys or update numeric counters. A single atomic transaction can set or delete multiple keys. Buckets can also contain HTTP-executable Lua scripts that access their keys and values. Developers can use the HTTP API or a JavaScript module from a browser, Node.js, or another CommonJS-compatible runtime. Cryptographically signed tokens can give time-limited access to keys matching a chosen prefix. Values are limited to 16 KB and names to 128 bytes. The documented limit is 1,000 requests per IP address per hour, with higher allowances on paid plans. A 14-day trial includes 10 MB of storage and 10,000 operations; after it ends, buckets become read-only and data remains for up to three months unless the account upgrades to Pro. Pro costs $19 a month; Enterprise costs $499 a month and includes on-premises deployment via Kubernetes or Docker.
Who it suits
KVdb.io suits developers building serverless apps or prototypes that need a key-value store accessible through HTTP or JavaScript. Teams needing on-premises deployment can consider its Enterprise plan.
What it does well
- REST API supports key operations and numeric counters.
- Multiple key changes can run in one atomic transaction.
- Lua scripts can execute over HTTP within buckets.
- Signed tokens can grant time-limited, prefix-based access.
- Enterprise includes on-premises deployment.
What to know first
- Values are limited to 16 KB.
- Names are limited to 128 bytes.
- Trial buckets become read-only after two weeks.
- Pro starts at $19 a month.
