Summary

SLAtech LTD is an Israeli software development company, operating since 2004. We help owners of apps built with Replit: we check the database and data handling, how keys are stored and the split between the development and published versions, take the project to production and keep developing it. The code stays in your account and repository. People define the architecture and make the decisions; AI only proposes.

Replit projects

Your Replit project is stuck? We will check it, fix it and take it to production

Replit Agent builds and runs an app from a description in words: interface, server, a PostgreSQL database and publishing in one place. The trouble starts later, when real users, payments and personal data arrive. The published app works with a different database than the development version, keys have to be passed to production separately, and every new request to Agent can break something that used to work. We audit Replit projects, continue their development, or rewrite what is not worth fixing. What we fixed, we stay accountable for.

What Replit does well

The full cycle in one place. Code, server, database and publishing, without separate infrastructure setup.

A real server. A Replit app has a server side where permission checks and keys can live, instead of being handed to the browser.

Database work through an ORM. Agent creates the schema itself and connects the app to PostgreSQL.

Checkpoints. Code and database changes can be rolled back to a saved state.

That is why a Replit project rarely has to be thrown away. More often it is enough to fix the specific places the tool is not responsible for.

Where Replit projects usually get stuck

Two databases

The development version and the published app use different databases. It is easy to test a fix on test data and miss that the schema or data in production are different.

Secrets for publishing

Keys added to the development environment have to be passed to the published app separately. Forget, and it crashes; mix them up, and it runs on test keys.

A rollback is not a backup

Checkpoints are handy during development, but they do not replace regular backups of the production database and a tested recovery plan.

Changes going in circles

The bigger the project, the more often a new request to Agent breaks a neighbouring feature. There are usually no tests to catch the breakage before users do.

Permissions on the server

There is a server, but permission checks are often not written everywhere. One forgotten route exposes other people's data.

Tied to the platform

Hosting, the database and secrets live in Replit. If a move to your own infrastructure is ever needed, it becomes a separate task.

What we check in a Replit project

1

Data access: whether every server route checks who is calling and whose data they want.

2

Keys and secrets: the development environment, publishing and the change history.

3

Development and published versions: how the database, schema and settings differ.

4

Payments and limits: where the decision is made and whether confirmations come straight from the payment provider.

5

Backups: whether the production database is backed up and whether recovery has been tested.

6

User sign-in: email confirmation, password reset, roles and permissions.

7

Third-party libraries: outdated and vulnerable versions.

8

Database queries and load: what slows down first as the number of users grows.

9

Repository and deployment: whether history is kept in Git, whether there are tests for the main scenarios.

The result: a written report in plain language, a list of issues ranked by risk, and a plan of fixes.

Three ways forward

Audit

A check against the list above, a written report and a plan of fixes. A fit if you carry on yourself or with your own team.

More about the audit

Continued development

We take the code from your Replit project or repository, close the critical issues and keep developing the product. What we fixed and wrote, we are accountable for.

Discuss continuing

Rewriting a part

Most often not everything needs rewriting, only what holds the data: permission checks, payments, database work. The rest can usually be kept.

Discuss a rewrite

How we choose between these paths is described in detail on the page about helping vibe-coded projects.

How we use AI ourselves

In Replit, Agent builds and runs the app from a description in words. We work differently. On client projects, people define the architecture and make the decisions. AI proposes a solution to a task a person has set, and we bring it into the project ourselves, after review. The AI agent gets no access to the code, databases, keys or passwords, and there is not a single line in the code that a person does not know about.

Frequently asked questions

Yes. We suggest a move only if it brings a clear benefit. More often it is enough to fix the problems where they are.

While you work on the app, it writes to one database, and the published app writes to another. A fix tested on development data can behave differently on real data. We check that the schema and settings of both versions match where they should.

Agent fixes what it sees in the current task. If the cause is elsewhere, or in the production data, the bug comes back. It takes a person who sees the project as a whole.

Access to the code is enough: an invitation to the project or access to the repository, read-only. We sign an NDA if needed.

It depends on two things: the size of the project and how far it has drifted, that is, how much in it needs changing and fixing. After the initial assessment we name the scope of work and the price, before any work starts.

Other AI tools

We work the same way with projects built on other tools. The general page: help for vibe-coded projects.
