KVdb.io review
A focused REST key-value service with useful controls, but a paid entry point and 16 KB value limit.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
KVdb.io is a hosted key-value database and REST API for application developers who need to store arbitrary key-value data without managing infrastructure. Its feature set covers bucket-based organization, access policies, per-key and bucket-level expiration, scoped access tokens, atomic multi-key transactions, numeric counters, Lua-based bucket scripting, and a web interface for updating keys. It is suited to small REST-based projects, serverless applications, prototypes, metrics, and similar developer workloads.
Pricing is structured around a 14-day trial, Pro, and Enterprise. The trial includes 10 MB of storage, 10,000 operations, three-month key expiration, and no credit card requirement. After the trial, buckets become read-only. Pro costs $19 per month and includes 1 GB of storage, 1 million operations, keys that never expire, and custom bucket scripts. Enterprise costs $499 per month and adds unlimited storage, unlimited operations, encryption at rest, and on-premises deployment through Kubernetes or Docker.
The platform is available through the web and API, with HTTP REST API and JavaScript/CommonJS API support. Access controls, TTL handling, transactions, counters, scripts, and the web interface give small application teams several ways to manage data without building those functions around a basic store. The documented 16 KB maximum value size makes it a focused option for compact records rather than larger payloads, while the $19 monthly starting price leaves less room for very small projects than an unlimited free plan would. Choose KVdb.io for a compact REST-centered workload with optional enterprise deployment; consider an alternative if larger individual values or broader integration coverage are central requirements.
