    The open source Firebase alternative. Follow to stay updated about our public Beta.

    That can be solved with RLS. The JWT usually contains the application user id(Customer) and assuming Document has an ownerId column, the SELECT policy for Document would contain the `ownerId = auth.uid()`[1] condition - this would ensure customers can't access documents that they don't own.

    This looks more fit to be discussed in. I'd recommend opening a discussion there.

    [1]: `auth.uid()` is just a wrapper over the `current_setting('', true)` mentioned in

  • protobuf-rules-gen

    This is an experimental protoc plugin that generates Firebase Rules for Cloud Firestore based on Google's Protocol Buffer format. This allows you to easily validate your data in a platform independent manner.

    A long time ago, I was the PM on Firestore security rules, which was intended to solve both of those issues. was the closest we got: declaring types as protobufs (because Google, of course) and then generating both security rules to guarantee validity as well as client types that would match. I wanted to add proto annotations to do additional validity (e.g. add a regex to validate the phone number string was correct, do length checks on strings, etc.).

    The short answer is that backend rules engines, either in their own DSL or bolted on to e.g. SQL, are pretty tough to get right, and have a super steep learning curve. IMO, AWS API Gateway with Lambda Authorizers get this most correct.

  • Appwrite

    Appwrite - The Open Source Firebase alternative introduces iOS support . Appwrite is an open source backend server that helps you build native iOS applications much faster with realtime APIs for authentication, databases, files storage, cloud functions and much more!

  • postgraphile

    Execute one command (or mount one Node.js middleware) and get an instant high-performance GraphQL API for your PostgreSQL database!

    I've personally found Postgraphile to be fantastic. Nicer to use than Hasura and fully OSS:

  • hippo

    The WebAssembly Platform

  • colorcal

    A travel planning tool that lets you color code and label the days of your trip.

    Using thin-backend has been one of the most delightful experiences I've had making an SPA with a simple backend. The developer experience with the generated TypeScript types is particularly great, the DB migrations remind me of Prisma, and knowing I have a standard Postgres db under the hood is comforting. It isn't a large or complex app, but Marc has been super responsive to bugs and feature suggestions so it has been fun to iterate on. You can find the code at

  • parse-server

    Parse Server for Node.js / Express

    And there are still some sites that host it for you for free (limited), but you can always self host it yourself...

  • OPA (Open Policy Agent)

    An open source, general-purpose policy engine.

    With regards to authorization – have y'all looked any at Open Policy Agent[1]? I think it could potentially be a good fit for the Supabase stack to implement policies not just in the database but also the gateway and potentially other components as well.

    It'd be super cool to be able to implement custom policies in rego code that could be re-used in several parts of the stack, and tested/verified/evolved independently from the stack.


  • Sonar

    Write Clean JavaScript Code. Always.. Sonar helps you commit clean code every time. With over 300 unique rules to find JavaScript bugs, code smells & vulnerabilities, Sonar finds the issues while you focus on the work.
