PerSQL / Render

PerSQL for Render

Edge SQLite for your Render services.

An isolated database per service, a branch per preview environment. Provision one, set three environment variables, and query with the SDK.

How it works

1

Connect

Sign in and provision an isolated SQLite database in your namespace.

2

Set three vars

Paste PERSQL_TOKEN, PERSQL_DATABASE, PERSQL_API_URL into the service's Environment, or an Env Group.

3

Query

Read the vars with @persql/sdk and run SQL. Preview environments get their own branch.

Then query it

import { PerSQL } from "@persql/sdk";

const db = new PerSQL({
  token: process.env.PERSQL_TOKEN,
  baseURL: process.env.PERSQL_API_URL,
}).database(process.env.PERSQL_DATABASE);

const { data } = await db.query("SELECT 1 AS ok");

A database per preview

Point a coding agent at the Render MCP. preview_recipe returns the CI snippet that spawns a preview-pr-<n> branch when a preview environment opens and deletes it on close.
