Back4App and Parse Alternatives: Where Parse Apps Go Next

If you run a Parse app on Back4App and want to move, you have two kinds of Back4App alternatives: keep Parse and host Parse Server yourself, or move to a different backend such as StitchDB, Supabase, Firebase or Appwrite. Keeping Parse is the least code change. Moving to a Postgres backend means more work up front but removes request-count pricing and gives you SQL. This guide covers both, with a concrete map from Parse concepts to Postgres.

#Back4App plans (as of November 2026)

From back4app.com/pricing/backend-as-a-service:

Back4App's value is that it runs Parse Server for you, with its dashboard, Cloud Code and SDKs. The usual reasons people look elsewhere are request caps (25K a month on Free is small for an active app), database sizes measured in single gigabytes, and wanting SQL rather than Parse queries.

#The two paths

#Path A: keep Parse, change the host

Parse Server is open source (Apache 2.0) and runs anywhere Node.js runs, with MongoDB or PostgreSQL as the database. Your client SDK code, Cloud Code and class-level permissions stay the same; you change the server URL and app keys.

Good for: large apps with lots of Cloud Code, teams with ops skills, anyone who wants zero client changes.

What you take on: a Node.js server, a database, file storage, push configuration, backups, upgrades and monitoring. Running Parse Server on PostgreSQL is supported, but Parse still owns the schema shape, so you don't get a hand-designed relational model for free.

#Path B: move to a different backend

Moving off Parse is a rewrite of the data layer in your clients. In return you get a backend that does not price by request count and, with a Postgres backend, a schema you control.

#Back4App alternatives compared

#Mapping Parse to Postgres

Most Parse concepts have a direct Postgres equivalent:

A Parse ACL that gives the owner read and write access becomes a policy:

create table public.posts (
  id text primary key,               -- old Parse objectId
  author_id uuid not null references auth.users on delete cascade,
  title text not null,
  created_at timestamptz not null default now()
);
alter table public.posts enable row level security;
create policy "authors manage posts" on public.posts
  for all to authenticated
  using (author_id = auth.uid()) with check (author_id = auth.uid());
create policy "anyone reads posts" on public.posts
  for select to anon, authenticated using (true);

A Cloud Code function like Parse.Cloud.define('postCount', ...) becomes a SQL function you call from the client:

create function public.post_count(author uuid) returns bigint
language sql stable as $$
  select count(*) from public.posts where author_id = author
$$;

const { data: count } = await stitchdb.rpc('post_count', { author: userId })

Scheduled Cloud Code jobs map to cron:

select cron.schedule('nightly-cleanup', '0 3 * * *',
  $$ delete from public.sessions_log where created_at < now() - interval '30 days' $$);

#The alternatives in detail

#StitchDB

StitchDB is the most "Parse-like" of the Postgres options in scope: besides the database, Auth, REST, GraphQL, Realtime and Storage, it has push notifications with an in-app inbox, in-app purchase verification, cron and queues, and SDKs for JavaScript, Flutter, Swift, Kotlin, C# (including Unity) and Python. Parse apps often rely on push, so this saves adding a separate vendor.

Plans as of November 2026: Free $0 (2 projects, 500 MB database, 1 GB files, 25 GB egress, 50 API requests per second), Pro $15.99/month (10 GB database, 100 GB files, 1 TB egress, 1,000 requests per second), Scale $49/month. Plans limit requests per second, not requests per month. See pricing.

Trade-offs: no self-hosting and no Parse API compatibility, so client code changes. Regions are in the EU only (Germany and Finland). It is a younger platform than Parse.

#Supabase

The open source Postgres backend with 17 AWS regions and self-hosting. Free projects pause after a week of inactivity; Pro from $25/month (as of November 2026). Check how you will send push notifications before you commit.

#Firebase

If you want to stay with an object/document model, Firestore is the natural target, and FCM covers push. Cloud Functions and Cloud Storage require the Blaze plan. See Firebase alternatives.

#Appwrite

Open source and self-hostable like Parse, with documents, a Messaging service, and functions in many runtimes. A good fit if you liked Parse's object model and want an actively developed project with a cloud option.

#Migration steps (to a Postgres backend)

1. Export data class by class, for example by paging through each class with the Parse REST API or SDK using the master key and saving JSON.
2. Create tables using the mapping above; keep objectId values so pointers resolve.
3. Load rows with a script that reads the JSON and inserts through the REST API with the service_role key, or with \copy into a staging jsonb table and an insert ... select.
4. Move users. If you cannot bring password hashes over, use magic links or a reset e-mail on first login, and keep the old objectId on the profile.
5. Move files from Parse Files into buckets.
6. Rewrite Cloud Code as SQL functions, triggers and Edge Functions.
7. Swap the client SDK screen by screen.

#FAQ

#Is Back4App the same as Parse?

Back4App hosts the open source Parse Server and adds its own dashboard and plans. You can run Parse Server yourself with Node.js and MongoDB or PostgreSQL.

#Can Parse Server use Postgres?

Yes. Parse Server supports MongoDB and PostgreSQL.

#What is the cheapest Back4App alternative?

Self-hosting Parse Server on a small VPS costs only the server. Among managed backends, free tiers exist on StitchDB, Supabase, Firebase and Appwrite; StitchDB Pro is $15.99/month as of November 2026.

#Do I have to rewrite my app to leave Parse?

Not if you self-host Parse Server. Moving to any non-Parse backend means changing the data and auth calls in your clients.

Move your Parse app to Postgres with push and cron included: start free on StitchDB.
