Definition
What is a Supabase agency?
A Supabase agency is an engineering team that designs, builds and maintains applications on Supabase, the open source Postgres platform. Its work covers database schema, Row Level Security policies, authentication, storage, Edge Functions and realtime features, plus the migrations, backups and monitoring a project needs to run safely in production.
Teams usually look for a Supabase development agency, or a Supabase consultant, when a build has stalled: the app works in a demo but is not safe or fast enough to launch.
- Platform
- Supabase, built on Postgres
- Licence
- Apache 2.0, self-hostable
- Hosting
- Supabase cloud or self-hosted
Where builds stall
Three faults that keep apps from launch
These are the faults Supabase experts see most often. Each one is documented, and each one is fixable.
- 01
Tables open to anyone
A table in an exposed schema without Row Level Security can be read and written with the public key. AI-generated apps often ship this way, and nothing fails until someone looks.
What we do: We audit every table, write tested policies, and move secret keys to the server.
- 02
Queries that slow as data grows
Policies run on every row. Without indexes on the filtered columns and cached auth calls, a query that was instant in the demo takes seconds with real data.
What we do: We profile the slow queries, add indexes, and rewrite policies the way Supabase documents.
- 03
No safe path to production
Schema changes made in the dashboard leave no migration history. There is no staging copy, auth email still uses the test sender, and no restore has ever been tried.
What we do: We put the schema in migrations, then add staging, custom SMTP and tested backups.
What we fix and build
The work that gets you live
Four areas of work. We start with the one that carries the most risk for you.
Security review and RLS
Every table, view, function and bucket checked against Supabase’s security advisors. Policies written per role and tested with real user sessions before release.
Migrations and environments
Your schema moves into version-controlled migrations. Staging and preview branches mirror production, so a change is tested before it touches live data.
Performance and connections
Indexes, query plans and policy rewrites for the slow paths. Connection pooling set up correctly for serverless, so traffic spikes do not exhaust the database.
Auth, email and recovery
Providers, MFA and rate limits configured. Custom SMTP for auth email. Backups and point-in-time recovery enabled, with a restore you have watched succeed.
How it runs
From a blocked build to a live release
Small steps, each with a visible result. You can stop after any of them.
- 01Call
Free 30-minute call
You show us the project and what blocks it. We agree the scope and the price of a pilot before any work starts.
- 02Pilot
Paid pilot, one deliverable
An engineer joins your Slack and repository within five working days. The pilot delivers one agreed result, usually the audit and the most urgent fixes.
- 03Build
Fix, test, demo
Work ships in small pull requests to your repository. You get a demo every week and a written update you can forward.
- 04Handover
Go live and hand over
We release with you, then hand over docs, runbooks and training. Your team can run the project without us.
Repair or replace
Keep Supabase, or move off it
Most stalled projects need repair, not a rewrite. Sometimes the platform is the wrong tool, and we say so.
The platformSupabase
Supabase is an open source Postgres development platform. Each project is a full Postgres database with authentication, file storage, Edge Functions, realtime subscriptions, vector search and auto-generated APIs, offered as a managed cloud service or self-hosted.
Where it is strong
- Standard Postgres: SQL, extensions, no proprietary language
- Auth, storage, APIs and realtime wired to one database
- Open source, self-hostable, documented migration paths
Where it stops
- Tables without Row Level Security are exposed through the API
- Edge Functions cap memory, CPU time and run duration
- Self-hosted lacks branching, managed backups and PITR
Supabase is the right tool when
- Your data is relational and your team can work in SQL
- You need auth, storage and APIs without building each one
- You want standard Postgres you can move elsewhere later
We would say no when
- Long or CPU-heavy jobs that exceed Edge Function limits
- Large analytical workloads better served by a warehouse
- Self-hosting with no team to run backups and upgrades
If another tool fits better, you hear it on the free call, before you pay for anything.
Two ways to work
A scoped fix, or an engineer on your team
Both start the same way: a free call, then a paid pilot with one deliverable.
A fixed scope, taken to production
We agree one outcome, such as a secured and launched app, and deliver it. Scope and price are set on the call.
- One agreed deliverable per pilot
- Weekly demo and written update
- Code in your repository and accounts
- Docs, runbooks and training at handover
A senior engineer on your team
A senior Supabase engineer works inside your Slack, repository and standups, for as long as the work needs.
- In your Slack within five working days
- Senior only, no juniors learning
- Works in English, in any timezone
- You own the code, IP and docs
FAQ
Questions about fixing a build
Straight answers, each complete on its own.
Can you fix a Supabase app built with Lovable or an AI tool?
Yes. We review the generated schema, enable Row Level Security where it is missing, write policies per role, and move secret keys out of the client. The app stays in your accounts and your repository throughout.
How do I know if my Supabase database is exposed?
Check that every table in an exposed schema has Row Level Security enabled, with policies that match your roles. Supabase’s security advisor flags the common gaps. We run that review and test the policies with real sessions.
Why is my Supabase app slow?
The usual causes are missing indexes, policies that call a function on every row, and serverless code that opens too many connections. We profile the queries, fix the policies, and set up pooling for your runtime.
Do you need access to our production data?
We work in your repository and your Supabase organization, with the access you grant. Where possible we work on a staging branch with seed data. An NDA is signed on request before any access.
How much does a Supabase agency cost?
We do not publish a price because the scope decides it. On the free 30-minute call we agree one deliverable and its price. No work starts until you have agreed both.
How fast can we hire Supabase developers from you?
An engineer can join your Slack and repository within five working days of the free call. The work begins with a paid pilot and one agreed deliverable, so you see results before committing to more.
Who owns the code and the Supabase project?
You do. The code, the IP and the docs are yours. Everything lives in your repository and your Supabase organization. At handover you receive docs, runbooks and training so your team can run it.

We worked with Seif on the React Native app for our vehicle-appraisal platform. What stood out most was how much ownership he takes: he thinks a feature through, raises edge cases before they turn into bugs, and delivers something that actually works. And then there is one more thing why I wanted to work with Seif after our very first call: Exceptional clear and consistent communication. It is a pleasure to work with him and his team!
