"string-database" names no specific product, so the request is ambiguous: it could mean a string-keyed or key-value store, a text/search database, or a general database. Ask which kind of string storage or search you need before picking a tool. Supabase 1 is a Postgres platform with an official SDK, and Elastic 3 is a search database; both are offered as candidates below.
A question back: Do you mean a key-value or string-keyed store, a full-text search engine, or a relational database for storing strings? Which language or platform will you use?
