Cinch SQL

Managed SQLite databases. The most deployed engine in the world — now as a cloud service. Scale-to-zero, one database per workload.

terminal

# Create a table

$ curl -X POST https://sql.cinchdb.dev/v1/sql \

-H "Authorization: Bearer cinch_abc123..." \

-d '{"sql": "CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT)"}'

# Insert and query

$ curl -X POST https://sql.cinchdb.dev/v1/sql \

-H "Authorization: Bearer cinch_abc123..." \

-d '{"sql": "INSERT INTO users (name) VALUES ('Alice')"}'

$ curl -X POST https://sql.cinchdb.dev/v1/sql \

-H "Authorization: Bearer cinch_abc123..." \

-d '{"sql": "SELECT * FROM users"}'

{"rows": [[1, "Alice"]]}

ENGINE

The most deployed database in the world. ACID, battle-tested, zero-configuration. Not an emulation — actual SQLite.

ACCESS

Query via HTTP API. Standard SQL syntax. Works from any language, any edge runtime, any serverless function.

ISOLATION

Each database is a separate SQLite file. Physical isolation, not row-level security.

ECONOMICS

No RDS instance running 24/7. Active databases use NVMe. Idle databases archive to cloud storage. Pay for what you use.
