Database · Production data

A database that still exists in production.

Preview has data. Production doesn't — or it does, and the wrong people can read it.

We work with PostgreSQL, Supabase, MySQL, MongoDB, and whatever the Replit already talks to. Architecture, migrations, auth against the database, permissions, queries, and the connection that only works in the editor.

Typical failure: the app used a local or Replit-hosted store in preview, then production has no DATABASE_URL, a stale replica, or migrations Agent never ran. We write the gap, then close it.

If Supabase or Postgres is the whole integration, those pages go deeper. This page is “the data layer is the reason we can't launch.”

What we do

  • 01

    Where the data lives

    Preview vs production, backups, and whether anyone can restore it.

  • 02

    Who can query it

    Keys, RLS, service roles in the client, and Agent shortcuts that skip permissions.

  • 03

    A production connection

    Env, migrations, and queries that survive more than one user.

What we skip

  • We don't dump the database and “start clean” unless the report says the data is already unsafe.
  • We don't put service keys in the frontend to unblock a demo.
  • We don't skip the review.

Frequently Asked Questions

Can you connect Replit with Supabase, PostgreSQL, or other databases?
Yes. We work with PostgreSQL, Supabase, MySQL, MongoDB, and other database systems. We can help with database architecture, migrations, authentication, permissions, queries, API connections, and troubleshooting existing database issues.
Can you improve the security of my Replit application?
Yes. We can review authentication, authorization, API endpoints, secrets and environment variables, database access, user permissions, dependencies, input validation, and other security-sensitive areas. For existing applications, we can also perform a focused security and architecture audit before making changes.
Can you make my Replit app production-ready?
Yes. We can take an existing Replit prototype or MVP and prepare it for real users. Depending on the project, this may include code cleanup, database improvements, authentication, security checks, API integrations, error handling, performance optimization, testing, deployment, and monitoring.
How do I get started with a Replit expert?
Send us a short description of your project, what you have already built, and what you need help with. If you already have a Replit project, you can also share its current status. We'll review your requirements and recommend the best next step, along with an estimated scope, timeline, and cost.
