Honest Review: Replit Agent

Replit Agent is the most ambitious AI coding tool we've tested. It doesn't just write code — it creates files, installs packages, sets up databases, and deploys. All from a natural language prompt.

What we built

We gave it three tasks: a CRUD app with auth, a data dashboard with charts, and an API with webhook integrations. Each took under an hour to scaffold.

The impressive parts

The initial generation is remarkably complete. It chose sensible defaults, set up proper project structure, and even wrote basic tests. The deploy pipeline worked on first try for two of three projects.

Where it breaks down

Customization is where the experience degrades. Once you need to deviate from the generated patterns, you're fighting the agent's assumptions. Error messages are often unhelpful because the agent made architectural choices you didn't ask for.

The database problem

For the CRUD app, it chose SQLite. Reasonable for prototyping, but migrating to Postgres required reworking the ORM layer the agent had tightly coupled to SQLite-specific features.

Verdict

Excellent for prototypes and demos. Not ready for production software that needs to evolve. Use it to validate ideas, then rebuild with intentional architecture.
